Print mode (`-p`) skips the dialog entirely. +3. **`--max-budget-usd` minimum is ~$0.05** — system prompt cache creation alone costs this much. Setting lower will error immediately. +4. **`--max-turns` is print-mode only** — ignored in interactive sessions. +5. **Claude may use `python` instead of `python`** — on systems without a `python` symlink, Claude's bash commands will fail on first try but it self-corrects. +6. **Session resumption requires same directory** — `--continue` finds the most recent session for the current working directory. +7. **`--json-schema` needs enough `--max-turns`** — Claude must read files before producing structured output, which takes multiple turns. +8. **Trust dialog only appears once per directory** — first-time only, then cached. +9. **Background tmux sessions persist** — always clean up with `tmux kill-session -t ` when done. +10. **Slash commands (like `/commit`) only work in interactive mode** — in `-p` mode, describe the task in natural language instead. +11. **`--bare` skips OAuth** — requires `ANTHROPIC_API_KEY` env var or an `apiKeyHelper` in settings. +12. **Context degradation is real** — AI output quality measurably degrades above 70% context window usage.

Audio, video, images, text, or pure math in, MP4/GIF/PNG sequence out. Full RGB color per character cell, 1080p 24fps default. No GPU. + +Built for [Hermes Agent](https://github.com/NousResearch/hermes-agent). Usable in any coding agent.

The agent gets the full pipeline: grid system, font rasterization, effect library, shader chain, audio analysis, parallel encoding. It writes the renderer, runs it, gets video. + +The output is actual video. Not terminal escape codes. Frames are computed as grids of colored characters, composited onto pixel canvases with pre-rasterized font bitmaps, post-processed through shaders, piped to ffmpeg. + +## Modes + +| Mode | Input | Output | +|------|-------|--------| +| Video-to-ASCII | A video file | ASCII recreation of the footage | +| Audio-reactive | An audio file | Visuals driven by frequency bands, beats, energy | +| Generative | Nothing | Procedural animation from math | +| Hybrid | Video + audio | ASCII video with audio-reactive overlays | +| Lyrics/text | Audio + timed text (SRT) | Karaoke-style text with effects | +| TTS narration | Text quotes + API key | Narrated video with typewriter text and generated speech | + +## Pipeline + +Every mode follows the same 6-stage path: + +``` +INPUT --> ANALYZE --> SCENE_FN --> TONEMAP --> SHADE --> ENCODE +``` + +1. **Input** loads source material (or nothing for generative). +2. **Analyze** extracts per-frame features. Audio gets 6-band FFT, RMS, spectral centroid, flatness, flux, beat detection with exponential decay. Video gets luminance, edges, motion. +3. **Scene function** returns a pixel canvas directly. Composes multiple character grids at different densities, value/hue fields, pixel blend modes. This is where the visuals happen. +4. **Tonemap** does adaptive percentile-based brightness normalization with per-scene gamma. ASCII on black is inherently dark. Linear multipliers don't work. This does. +5. **Shade** runs a `ShaderChain` (38 composable shaders) plus a `FeedbackBuffer` for temporal recursion with spatial transforms. +6. **Encode** pipes raw RGB frames to ffmpeg for H.264 encoding.

Two 50% gray layers screen to 75%. The go-to safe blend. +- `add` — simple addition, clips at white. Good for sparkles, glows, particle overlays. +- `colordodge` — extreme brightening at overlap zones. Can blow out. Use low opacity (0.3-0.5). +- `linearlight` — aggressive brightening. Similar to add but with offset. + +**Modes that darken** (avoid with dark inputs): +- `multiply` — darkens everything. Only use when both layers are already bright. +- `overlay` — darkens when base < 0.5, brightens when base > 0.5. Crushes dark inputs: `2 * 0.12 * 0.12 = 0.03`. Use `screen` instead for dark material. +- `colorburn` — extreme darkening at overlap zones. + +**Modes that create contrast**: +- `softlight` — gentle contrast. Good for subtle texture overlay. +- `hardlight` — strong contrast. Like overlay but keyed on the top layer. +- `vividlight` — very aggressive contrast. Use sparingly. + +**Modes that create color effects**: +- `difference` — XOR-like patterns. Two identical layers difference to black; offset layers create wild colors. Great for psychedelic looks. +- `exclusion` — softer version of difference. Creates complementary color patterns. +- `hard_mix` — posterizes to pure black/white/saturated color at intersections. + +**Modes for texture blending**: +- `grain_extract` / `grain_merge` — extract a texture from one layer, apply it to another. + +### Multi-Layer Chaining + +```python +# Pattern: render layers -> blend sequentially +canvas_a = _render_vf(r, "md", vf_plasma, hf_angle(0.0), PAL_DENSE, f, t, S) +canvas_b = _render_vf(r, "sm", vf_vortex, hf_time_cycle(0.1), PAL_RUNE, f, t, S) +canvas_c = _render_vf(r, "lg", vf_rings, hf_distance(), PAL_BLOCKS, f, t, S) + +result = blend_canvas(canvas_a, canvas_b, "screen", 0.8) +result = blend_canvas(result, canvas_c, "difference", 0.6) +``` + +Order matters: `screen(A, B)` is commutative, but `difference(screen(A,B), C)` differs from `difference(A, screen(B,C))`. + +### Linear-Light Blend Modes + +Standard `blend_canvas()` operates in sRGB space — the raw byte values.

If you use a lambda or closure, you get: + +``` +_pickle.PicklingError: Can't pickle at 0x...> +``` + +**Fix**: Define all scene functions at module top level. Lambdas used inside `_render_vf()` as val_fn/hue_fn are fine because they execute within the worker process — they're not pickled across process boundaries. + +### macOS spawn vs Linux fork + +On macOS, `multiprocessing` defaults to `spawn` (full serialization). On Linux, it defaults to `fork` (copy-on-write). This means: + +- **macOS**: Feature arrays are serialized per worker (~57KB for 30s video, but scales with duration). Each worker re-imports the entire module. +- **Linux**: Feature arrays are shared via COW. Workers inherit the parent's memory. + +**Impact**: On macOS, module-level code (like `detect_hardware()`) runs in every worker process.

Check for accidental Python loops in effects (should be numpy only) + +--- + +## Common Mistakes + +### Using `r.S` vs the `S` Parameter + +The v2 scene protocol passes `S` (the state dict) as an explicit parameter. But `S` IS `r.S` — they're the same object. Both work: + +```python +def fx_scene(r, f, t, S): + S["counter"] = S.get("counter", 0) + 1 # via parameter (preferred) + r.S["counter"] = r.S.get("counter", 0) + 1 # via renderer (also works) +``` + +Use the `S` parameter for clarity. The explicit parameter makes it obvious that the function has persistent state. + +### Forgetting to Handle Empty Feature Values + +Audio features default to 0.0 if the audio is silent. Use `.get()` with sensible defaults: + +```python +energy = f.get("bass", 0.3) # default to 0.3, not 0 +``` + +If you default to 0, effects go blank during silence. + +### Writing New Files Instead of Editing Existing State + +A common bug in particle systems: creating new arrays every frame instead of updating persistent state. + +```python +# WRONG — particles reset every frame +S["px"] = [] +for _ in range(100): + S["px"].append(random.random()) + +# RIGHT — only initialize once, update each frame +if "px" not in S: + S["px"] = [] +# ... emit new particles based on beats +# ... update existing particles +``` + +### Not Clipping Value Fields + +Value fields should be [0, 1]. If they exceed this range, `val2char()` produces index errors: + +```python +# WRONG — vf_plasma() * 1.5 can exceed 1.0 +val = vf_plasma(g, f, t, S) * 1.5 + +# RIGHT — clip after scaling +val = np.clip(vf_plasma(g, f, t, S) * 1.5, 0, 1) +``` + +The `_render_vf()` helper clips automatically, but if you're building custom scenes, clip explicitly. + +## Brightness Best Practices + +- Dense animated backgrounds — never flat black, always fill the grid +- Vignette minimum clamped to 0.15 (not 0.12) +- Bloom threshold 130 (not 170) so more pixels contribute to glow +- Use `screen` blend mode (not `overlay`) for dark ASCII layers — overlay squares dark values: `2 * 0.12 * 0.12 = 0.03` +- FeedbackBuffer decay minimum 0.5 — below that, feedback disappears too fast to see +- Value field floor: `vf * 0.8 + 0.05` ensures no cell is truly zero +- Per-scene gamma overrides: default 0.75, solarize 0.55, posterize 0.50, bright scenes 0.85 +- Test frames early: render single frames at key timestamps before committing to full render + +**Quick checklist before full render:** +1.

Never manipulate DOM in `draw()`. See `references/troubleshooting.md` § Performance. + +### Seeded Randomness — Always + +Every generative sketch must be reproducible. Same seed, same output. + +```javascript +function setup() { + randomSeed(CONFIG.seed); + noiseSeed(CONFIG.seed); + // All random() and noise() calls now deterministic +} +``` + +Never use `Math.random()` for generative content — only for performance-critical non-visual code. Always `random()` for visual elements. If you need a random seed: `CONFIG.seed = floor(random(99999))`. + +### Generative Art Platform Support (fxhash / Art Blocks) + +For generative art platforms, replace p5's PRNG with the platform's deterministic random: + +```javascript +// fxhash convention +const SEED = $fx.hash; // unique per mint +const rng = $fx.rand; // deterministic PRNG +$fx.features({ palette: 'warm', complexity: 'high' }); + +// In setup(): +randomSeed(SEED); // for p5's noise() +noiseSeed(SEED); + +// Replace random() with rng() for platform determinism +let x = rng() * width; // instead of random(width) +``` + +See `references/export-pipeline.md` § Platform Export. + +### Color Mode — Use HSB + +HSB (Hue, Saturation, Brightness) is dramatically easier to work with than RGB for generative art: + +```javascript +colorMode(HSB, 360, 100, 100, 100); +// Now: fill(hue, sat, bri, alpha) +// Rotate hue: fill((baseHue + offset) % 360, 80, 90) +// Desaturate: fill(hue, sat * 0.3, bri) +// Darken: fill(hue, sat, bri * 0.5) +``` + +Never hardcode raw RGB values. Define a palette object, derive variations procedurally. See `references/color-systems.md`. + +### Noise — Multi-Octave, Not Raw + +Raw `noise(x, y)` looks like smooth blobs. Layer octaves for natural texture: + +```javascript +function fbm(x, y, octaves = 4) { + let val = 0, amp = 1, freq = 1, sum = 0; + for (let i = 0; i < octaves; i++) { + val += noise(x * freq, y * freq) * amp; + sum += amp; + amp *= 0.5; + freq *= 2; + } + return val / sum; +} +``` + +For flowing organic forms, use **domain warping**: feed noise output back as noise input coordinates. See `references/visual-effects.md`. + +### createGraphics() for Layers — Not Optional + +Flat single-pass rendering looks flat. Use offscreen buffers for composition: + +```javascript +let bgLayer, fgLayer, trailLayer; +function setup() { + createCanvas(1920, 1080); + bgLayer = createGraphics(width, height); + fgLayer = createGraphics(width, height); + trailLayer = createGraphics(width, height); +} +function draw() { + renderBackground(bgLayer); + renderTrails(trailLayer); // persistent, fading + renderForeground(fgLayer); // cleared each frame + image(bgLayer, 0, 0); + image(trailLayer, 0, 0); + image(fgLayer, 0, 0); +} +``` + +### Performance — Vectorize Where Possible + +p5.js draw calls are expensive. For thousands of particles: + +```javascript +// SLOW: individual shapes +for (let p of particles) { + ellipse(p.x, p.y, p.size); +} + +// FAST: single shape with beginShape() +beginShape(POINTS); +for (let p of particles) { + vertex(p.x, p.y); +} +endShape(); + +// FASTEST: pixel buffer for massive counts +loadPixels(); +for (let p of particles) { + let idx = 4 * (floor(p.y) * width + floor(p.x)); + pixels[idx] = r; pixels[idx+1] = g; pixels[idx+2] = b; pixels[idx+3] = 255; +} +updatePixels(); +``` + +See `references/troubleshooting.md` § Performance. + +### Instance Mode for Multiple Sketches + +Global mode pollutes `window`. For production, use instance mode: + +```javascript +const sketch = (p) => { + p.setup = function() { + p.createCanvas(800, 800); + }; + p.draw = function() { + p.background(0); + p.ellipse(p.mouseX, p.mouseY, 50); + }; +}; +new p5(sketch, 'canvas-container'); +``` + +Required when embedding multiple sketches on one page or integrating with frameworks. + +### WebGL Mode Gotchas + +- `createCanvas(w, h, WEBGL)` — origin is center, not top-left +- Y-axis is inverted (positive Y goes up in WEBGL, down in P2D) +- `translate(-width/2, -height/2)` to get P2D-like coordinates +- `push()`/`pop()` around every transform — matrix stack overflows silently +- `texture()` before `rect()`/`plane()` — not after +- Custom shaders: `createShader(vert, frag)` — test on multiple browsers + +### Export — Key Bindings Convention + +Every sketch should include these in `keyPressed()`: + +```javascript +function keyPressed() { + if (key === 's' || key === 'S') saveCanvas('output', 'png'); + if (key === 'g' || key === 'G') saveGif('output', 5); + if (key === 'r' || key === 'R') { randomSeed(millis()); noiseSeed(millis()); } + if (key === ' ') CONFIG.paused = !CONFIG.paused; +} +``` + +### Headless Video Export — Use noLoop() + +For headless rendering via Puppeteer, the sketch **must** use `noLoop()` in setup. Without it, p5's draw loop runs freely while screenshots are slow — the sketch races ahead and you get skipped/duplicate frames. + +```javascript +function setup() { + createCanvas(1920, 1080); + pixelDensity(1); + noLoop(); // capture script controls frame advance + window._p5Ready = true; // signal readiness to capture script +} +``` + +The bundled `scripts/export-frames.js` detects `_p5Ready` and calls `redraw()` once per capture for exact 1:1 frame correspondence. See `references/export-pipeline.md` § Deterministic Capture. + +For multi-scene videos, use the per-clip architecture: one HTML per scene, render independently, stitch with `ffmpeg -f concat`.

Blend selectively — keep mappings that produce interesting emergent visuals +4. Code the blend as a unified system, not two systems side-by-side + +### SCAMPER Transformation +Take a known generative pattern (flow field, particle system, L-system, cellular automata) and systematically transform it: +- **Substitute**: replace circles with text characters, lines with gradients +- **Combine**: merge two patterns (flow field + voronoi) +- **Adapt**: apply a 2D pattern to a 3D projection +- **Modify**: exaggerate scale, warp the coordinate space +- **Purpose**: use a physics sim for typography, a sorting algorithm for color +- **Eliminate**: remove the grid, remove color, remove symmetry +- **Reverse**: run the simulation backward, invert the parameter space + +### Distance Association +1. Anchor on the user's concept (e.g., "loneliness") +2. Generate associations at three distances: + - Close (obvious): empty room, single figure, silence + - Medium (interesting): one fish in a school swimming the wrong way, a phone with no notifications, the gap between subway cars + - Far (abstract): prime numbers, asymptotic curves, the color of 3am +3. Develop the medium-distance associations — they're specific enough to visualize but unexpected enough to be interesting diff --git a/skills/creative/p5js/references/animation.md b/skills/creative/p5js/references/animation.md new file mode 100644 index 0000000..ab3d69c --- /dev/null +++ b/skills/creative/p5js/references/animation.md @@ -0,0 +1,439 @@ +# Animation + +## Frame-Based Animation + +### The Draw Loop + +```javascript +function draw() { + // Called ~60 times/sec by default + // frameCount — integer, starts at 1 + // deltaTime — ms since last frame (use for framerate-independent motion) + // millis() — ms since sketch start +} +``` + +### Time-Based vs Frame-Based + +```javascript +// Frame-based (speed varies with framerate) +x += speed;

Build bloom: downsample → blur → upscale + bloomBuf.clear(); + bloomBuf.image(scene, 0, 0, width / 4, height / 4); // 4x downsample + bloomBuf.filter(BLUR, 6); // blur the small version + + // 3. Composite: scene + additive bloom + background(0); + image(scene, 0, 0); // base layer + blendMode(ADD); // additive = glow + tint(255, 80); // control bloom intensity (0-255) + image(bloomBuf, 0, 0, width, height); // upscale back to full size + noTint(); + blendMode(BLEND); // ALWAYS reset blend mode +} +``` + +**Tuning:** +- Downsample ratio (1/4 is standard, 1/8 for softer, 1/2 for tighter) +- Blur radius (4-8 typical, higher = wider glow) +- Tint alpha (40-120, controls glow intensity) +- Update bloom every N frames to save perf: `if (frameCount % 2 === 0) { ... }` + +**Common mistake:** Forgetting `blendMode(BLEND)` after the ADD pass — everything drawn after will be additive. + +### Trail Buffer Brightness + +Trail accumulation via `createGraphics()` + semi-transparent fade rect is the standard technique for particle trails, but **trails are always dimmer than you expect**. The fade rect's alpha compounds multiplicatively every frame. + +```javascript +// The fade rect alpha controls trail length AND brightness: +trailBuf.fill(0, 0, 0, alpha); +trailBuf.rect(0, 0, width, height); + +// alpha=5 → very long trails, very dim (content fades to 50% in ~35 frames) +// alpha=10 → long trails, dim +// alpha=20 → medium trails, visible +// alpha=40 → short trails, bright +// alpha=80 → very short trails, crisp +``` + +**The trap:** You set alpha=5 for long trails, but particle strokes at alpha=30 are invisible because they fade before accumulating enough density. Either: +- **Boost stroke alpha** to 80-150 (not the intuitive 20-40) +- **Reduce fade alpha** but accept shorter trails +- **Use additive blending** for the strokes: bright particles accumulate, dim ones stay dark + +```javascript +// WRONG: low fade + low stroke = invisible +trailBuf.fill(0, 0, 0, 5); // long trails +trailBuf.rect(0, 0, W, H); +trailBuf.stroke(255, 30); // too dim to ever accumulate +trailBuf.line(px, py, x, y); + +// RIGHT: low fade + high stroke = visible long trails +trailBuf.fill(0, 0, 0, 5); +trailBuf.rect(0, 0, W, H); +trailBuf.stroke(255, 100); // bright enough to persist through fade +trailBuf.line(px, py, x, y); +``` + +### Reaction-Diffusion (Gray-Scott) + +```javascript +class ReactionDiffusion { + constructor(w, h) { + this.w = w;

Visual Theme & Atmosphere + +Airbnb's website is a warm, photography-forward marketplace that feels like flipping through a travel magazine where every page invites you to book. The design operates on a foundation of pure white (`#ffffff`) with the iconic Rausch Red (`#ff385c`) — named after Airbnb's first street address — serving as the singular brand accent. The result is a clean, airy canvas where listing photography, category icons, and the red CTA button are the only sources of color. + +The typography uses Airbnb Cereal VF — a custom variable font that's warm and approachable, with rounded terminals that echo the brand's "belong anywhere" philosophy. The font operates in a tight weight range: 500 (medium) for most UI, 600 (semibold) for emphasis, and 700 (bold) for primary headings. Slight negative letter-spacing (-0.18px to -0.44px) on headings creates a cozy, intimate reading experience rather than the compressed efficiency of tech companies. + +What distinguishes Airbnb is its palette-based token system (`--palette-*`) and multi-layered shadow approach. The primary card shadow uses a three-layer stack (`rgba(0,0,0,0.02) 0px 0px 0px 1px, rgba(0,0,0,0.04) 0px 2px 6px, rgba(0,0,0,0.1) 0px 4px 8px`) that creates a subtle, warm lift. Combined with generous border-radius (8px–32px), circular navigation controls (50%), and a category pill bar with horizontal scrolling, the interface feels tactile and inviting — designed for browsing, not commanding. + +**Key Characteristics:** +- Pure white canvas with Rausch Red (`#ff385c`) as singular brand accent +- Airbnb Cereal VF — custom variable font with warm, rounded terminals +- Palette-based token system (`--palette-*`) for systematic color management +- Three-layer card shadows: border ring + soft blur + stronger blur +- Generous border-radius: 8px buttons, 14px badges, 20px cards, 32px large elements +- Circular navigation controls (50% radius) +- Photography-first listing cards — images are the hero content +- Near-black text (`#222222`) — warm, not cold +- Luxe Purple (`#460479`) and Plus Magenta (`#92174d`) for premium tiers + +## 2.

Visual Theme & Atmosphere + +Apple's website is a masterclass in controlled drama — vast expanses of pure black and near-white serve as cinematic backdrops for products that are photographed as if they were sculptures in a gallery. The design philosophy is reductive to its core: every pixel exists in service of the product, and the interface itself retreats until it becomes invisible. This is not minimalism as aesthetic preference; it is minimalism as reverence for the object. + +The typography anchors everything. San Francisco (SF Pro Display for large sizes, SF Pro Text for body) is Apple's proprietary typeface, engineered with optical sizing that automatically adjusts letterforms depending on point size. At display sizes (56px), weight 600 with a tight line-height of 1.07 and subtle negative letter-spacing (-0.28px) creates headlines that feel machined rather than typeset — precise, confident, and unapologetically direct. At body sizes (17px), the tracking loosens slightly (-0.374px) and line-height opens to 1.47, creating a reading rhythm that is comfortable without ever feeling slack. + +The color story is starkly binary. Product sections alternate between pure black (`#000000`) backgrounds with white text and light gray (`#f5f5f7`) backgrounds with near-black text (`#1d1d1f`). This creates a cinematic pacing — dark sections feel immersive and premium, light sections feel open and informational. The only chromatic accent is Apple Blue (`#0071e3`), reserved exclusively for interactive elements: links, buttons, and focus states. This singular accent color in a sea of neutrals gives every clickable element unmistakable visibility. + +**Key Characteristics:** +- SF Pro Display/Text with optical sizing — letterforms adapt automatically to size context +- Binary light/dark section rhythm: black (`#000000`) alternating with light gray (`#f5f5f7`) +- Single accent color: Apple Blue (`#0071e3`) reserved exclusively for interactive elements +- Product-as-hero photography on solid color fields — no gradients, no textures, no distractions +- Extremely tight headline line-heights (1.07-1.14) creating compressed, billboard-like impact +- Full-width section layout with centered content — the viewport IS the canvas +- Pill-shaped CTAs (980px radius) creating soft, approachable action buttons +- Generous whitespace between sections allowing each product moment to breathe + +## 2.

Display versions have wider letter spacing and thinner strokes optimized for large sizes; Text versions are tighter and sturdier for small sizes. This means the font literally changes its DNA based on context. +- **Weight restraint**: The scale spans 300 (light) to 700 (bold) but most text lives at 400 (regular) and 600 (semibold). Weight 300 appears only on large decorative text. Weight 700 is rare, used only for bold card titles. +- **Negative tracking at all sizes**: Unlike most systems that only track headlines, Apple applies subtle negative letter-spacing even at body sizes (-0.374px at 17px, -0.224px at 14px, -0.12px at 12px). This creates universally tight, efficient text. +- **Extreme line-height range**: Headlines compress to 1.07 while body text opens to 1.47, and some button contexts stretch to 2.41. This dramatic range creates clear visual hierarchy through rhythm alone. + +## 4.

This allows precise micro-adjustments for typography and icon alignment. + +### Grid & Container +- Max content width: approximately 980px (the recurring "980px radius" in pill buttons echoes this width) +- Hero: full-viewport-width sections with centered content block +- Product grids: 2-3 column layouts within centered container +- Single-column for hero moments — one product, one message, full attention +- No visible grid lines or gutters — spacing creates implied structure + +### Whitespace Philosophy +- **Cinematic breathing room**: Each product section occupies a full viewport height (or close to it). The whitespace between products is not empty — it is the pause between scenes in a film. +- **Vertical rhythm through color blocks**: Rather than using spacing alone to separate sections, Apple uses alternating background colors (black, `#f5f5f7`, white). Each color change signals a new "scene." +- **Compression within, expansion between**: Text blocks are tightly set (negative letter-spacing, tight line-heights) while the space surrounding them is vast. This creates a tension between density and openness. + +### Border Radius Scale +- Micro (5px): Small containers, link tags +- Standard (8px): Buttons, product cards, image containers +- Comfortable (11px): Search inputs, filter buttons +- Large (12px): Feature panels, lifestyle image containers +- Full Pill (980px): CTA links ("Learn more", "Shop"), navigation pills +- Circle (50%): Media controls (play/pause, arrows) + +## 6.

The primary shadow (`3px 5px 30px` with 0.22 opacity) is soft, wide, and offset — mimicking a diffused studio light casting a natural shadow beneath a physical object. This reinforces the "product as physical sculpture" metaphor. Most elements have NO shadow at all; elevation comes from background color contrast (dark card on darker background, or light card on slightly different gray). + +### Decorative Depth +- Navigation glass: the translucent, blurred navigation bar is the most recognizable depth element, creating a sense of floating UI above scrolling content +- Section color transitions: depth is implied by the alternation between black and light gray sections rather than by shadows +- Product photography shadows: the products themselves cast shadows in their photography, so the UI doesn't need to add synthetic ones + +## 7.

Visual Theme & Atmosphere + +BMW's website is automotive engineering made visual — a design system that communicates precision, performance, and German industrial confidence. The page alternates between deep dark hero sections (featuring full-bleed automotive photography) and clean white content areas, creating a cinematic rhythm reminiscent of a luxury car showroom where vehicles are lit against darkness. The BMW CI2020 design language (their corporate identity refresh) defines every element. + +The typography is built on BMWTypeNextLatin — a proprietary typeface in two variants: BMWTypeNextLatin Light (weight 300) for massive uppercase display headings, and BMWTypeNextLatin Regular for body and UI text. The 60px uppercase headline at weight 300 is the defining typographic gesture — light-weight type that whispers authority rather than shouting it. The fallback stack includes Helvetica and Japanese fonts (Hiragino, Meiryo), reflecting BMW's global presence. + +What makes BMW distinctive is its CSS variable-driven theming system. Context-aware variables (`--site-context-highlight-color: #1c69d4`, `--site-context-focus-color: #0653b6`, `--site-context-metainfo-color: #757575`) suggest a design system built for multi-brand, multi-context deployment where colors can be swapped globally. The blue highlight color (`#1c69d4`) is BMW's signature blue — used sparingly for interactive elements and focus states, never decoratively. Zero border-radius was detected — BMW's design is angular, sharp-cornered, and uncompromisingly geometric. + +**Key Characteristics:** +- BMWTypeNextLatin Light (weight 300) uppercase for display — whispered authority +- BMW Blue (`#1c69d4`) as singular accent — used only for interactive elements +- Zero border-radius detected — angular, sharp-cornered, industrial geometry +- Dark hero photography + white content sections — showroom lighting rhythm +- CSS variable-driven theming: `--site-context-*` tokens for brand flexibility +- Weight 900 for navigation emphasis — extreme contrast with 300 display +- Tight line-heights (1.15–1.30) throughout — compressed, efficient, German engineering +- Full-bleed automotive photography as primary visual content + +## 2.

Visual Theme & Atmosphere + +Cal.com's website is a masterclass in monochromatic restraint — a grayscale world where boldness comes not from color but from the sheer confidence of black text on white space. Inspired by Uber's minimal aesthetic, the palette is deliberately stripped of hue: near-black headings (`#242424`), mid-gray secondary text (`#898989`), and pure white surfaces. Color is treated as a foreign substance — when it appears (a rare blue link, a green trust badge), it feels like a controlled accent in an otherwise black-and-white photograph. + +Cal Sans, the brand's custom geometric display typeface designed by Mark Davis, is the visual centerpiece. Letters are intentionally spaced extremely close at large sizes, creating dense, architectural headlines that feel like they're carved into the page. At 64px and 48px, Cal Sans headings sit at weight 600 with a tight 1.10 line-height — confident, compressed, and immediately recognizable. For body text, the system switches to Inter, providing "rock-solid" readability that complements Cal Sans's display personality. The typography pairing creates a clear division: Cal Sans speaks, Inter explains. + +The elevation system is notably sophisticated for a minimal site — 11 shadow definitions create a nuanced depth hierarchy using multi-layered shadows that combine ring borders (`0px 0px 0px 1px`), soft diffused shadows, and inset highlights. This shadow-first approach to depth (rather than border-first) gives surfaces a subtle three-dimensionality that feels modern and polished. Built on Framer with a border-radius scale from 2px to 9999px (pill), Cal.com balances geometric precision with soft, rounded interactive elements. + +**Key Characteristics:** +- Purely grayscale brand palette — no brand colors, boldness through monochrome +- Cal Sans custom geometric display font with extremely tight default letter-spacing +- Multi-layered shadow system (11 definitions) with ring borders + diffused shadows + inset highlights +- Cal Sans for headings, Inter for body — clean typographic division +- Wide border-radius scale from 2px to 9999px (pill) — versatile rounding +- White canvas with near-black (#242424) text — maximum contrast, zero decoration +- Product screenshots as primary visual content — the scheduling UI sells itself +- Built on Framer platform + +## 2.

Visual Theme & Atmosphere + +Claude's interface is a literary salon reimagined as a product page — warm, unhurried, and quietly intellectual. The entire experience is built on a parchment-toned canvas (`#f5f4ed`) that deliberately evokes the feeling of high-quality paper rather than a digital surface. Where most AI product pages lean into cold, futuristic aesthetics, Claude's design radiates human warmth, as if the AI itself has good taste in interior design. + +The signature move is the custom Anthropic Serif typeface — a medium-weight serif with generous proportions that gives every headline the gravitas of a book title. Combined with organic, hand-drawn-feeling illustrations in terracotta (`#c96442`), black, and muted green, the visual language says "thoughtful companion" rather than "powerful tool." The serif headlines breathe at tight-but-comfortable line-heights (1.10–1.30), creating a cadence that feels more like reading an essay than scanning a product page. + +What makes Claude's design truly distinctive is its warm neutral palette. Every gray has a yellow-brown undertone (`#5e5d59`, `#87867f`, `#4d4c48`) — there are no cool blue-grays anywhere. Borders are cream-tinted (`#f0eee6`, `#e8e6dc`), shadows use warm transparent blacks, and even the darkest surfaces (`#141413`, `#30302e`) carry a barely perceptible olive warmth.

Deliberately earthy and un-tech. +- **Coral Accent** (`#d97757`): A lighter, warmer variant of the brand color used for text accents, links on dark surfaces, and secondary emphasis. + +### Secondary & Accent +- **Error Crimson** (`#b53333`): A deep, warm red for error states — serious without being alarming. +- **Focus Blue** (`#3898ec`): Standard blue for input focus rings — the only cool color in the entire system, used purely for accessibility. + +### Surface & Background +- **Parchment** (`#f5f4ed`): The primary page background — a warm cream with a yellow-green tint that feels like aged paper. The emotional foundation of the entire design. +- **Ivory** (`#faf9f5`): The lightest surface — used for cards and elevated containers on the Parchment background. Barely distinguishable but creates subtle layering. +- **Pure White** (`#ffffff`): Reserved for specific button surfaces and maximum-contrast elements. +- **Warm Sand** (`#e8e6dc`): Button backgrounds and prominent interactive surfaces — a noticeably warm light gray. +- **Dark Surface** (`#30302e`): Dark-theme containers, nav borders, and elevated dark elements — warm charcoal. +- **Deep Dark** (`#141413`): Dark-theme page background and primary dark surface. + +### Neutrals & Text +- **Charcoal Warm** (`#4d4c48`): Button text on light warm surfaces — the go-to dark-on-light text. +- **Olive Gray** (`#5e5d59`): Secondary body text — a distinctly warm medium-dark gray. +- **Stone Gray** (`#87867f`): Tertiary text, footnotes, and de-emphasized metadata. +- **Dark Warm** (`#3d3d3a`): Dark text links and emphasized secondary text. +- **Warm Silver** (`#b0aea5`): Text on dark surfaces — a warm, parchment-tinted light gray. + +### Semantic & Accent +- **Border Cream** (`#f0eee6`): Standard light-theme border — barely visible warm cream, creating the gentlest possible containment. +- **Border Warm** (`#e8e6dc`): Prominent borders, section dividers, and emphasized containment on light surfaces. +- **Border Dark** (`#30302e`): Standard border on dark surfaces — maintains the warm tone. +- **Ring Warm** (`#d1cfc5`): Shadow ring color for button hover/focus states. +- **Ring Subtle** (`#dedc01`): Secondary ring variant for lighter interactive surfaces. +- **Ring Deep** (`#c2c0b6`): Deeper ring for active/pressed states. + +### Gradient System +- Claude's design is **gradient-free** in the traditional sense.

Anthropic Sans handles all functional UI text — buttons, labels, navigation — with quiet efficiency. +- **Single weight for serifs**: All Anthropic Serif headings use weight 500 — no bold, no light. This creates a consistent "voice" across all headline sizes, as if the same author wrote every heading. +- **Relaxed body line-height**: Most body text uses 1.60 line-height — significantly more generous than typical tech sites (1.4–1.5).

The signature `0px 0px 0px 1px` pattern creates a border-like halo that's softer than an actual border — it's a shadow pretending to be a border, or a border that's technically a shadow.

Visual Theme & Atmosphere + +Clay's website is a warm, playful celebration of color that treats B2B data enrichment like a craft rather than an enterprise chore. The design language is built on a foundation of warm cream backgrounds (`#faf9f7`) and oat-toned borders (`#dad4c8`, `#eee9df`) that give every surface the tactile quality of handmade paper. Against this artisanal canvas, a vivid swatch palette explodes with personality — Matcha green, Slushie cyan, Lemon gold, Ube purple, Pomegranate pink, Blueberry navy, and Dragonfruit magenta — each named like flavors at a juice bar, not colors in an enterprise UI kit. + +The typography is anchored by Roobert, a geometric sans-serif with character, loaded with an extensive set of OpenType stylistic sets (`"ss01"`, `"ss03"`, `"ss10"`, `"ss11"`, `"ss12"`) that give the text a distinctive, slightly quirky personality. At display scale (80px, weight 600), Roobert uses aggressive negative letter-spacing (-3.2px) that compresses headlines into punchy, billboard-like statements. Space Mono serves as the monospace companion for code and technical labels, completing the craft-meets-tech duality. + +What makes Clay truly distinctive is its hover micro-animations: buttons on hover rotate slightly (`rotateZ(-8deg)`), translate upward (`translateY(-80%)`), change background to a contrasting swatch color, and cast a hard offset shadow (`rgb(0,0,0) -7px 7px`). This playful hover behavior — where a button literally tilts and jumps on interaction — creates a sense of physical delight that's rare in B2B software. Combined with generously rounded containers (24px–40px radius), dashed borders alongside solid ones, and a multi-layer shadow system that includes inset highlights, Clay feels like a design system that was made by people who genuinely enjoy making things. + +**Key Characteristics:** +- Warm cream canvas (`#faf9f7`) with oat-toned borders (`#dad4c8`) — artisanal, not clinical +- Named swatch palette: Matcha, Slushie, Lemon, Ube, Pomegranate, Blueberry, Dragonfruit +- Roobert font with 5 OpenType stylistic sets — quirky geometric character +- Playful hover animations: rotateZ(-8deg) + translateY(-80%) + hard offset shadow +- Space Mono for code and technical labels +- Generous border radius: 24px cards, 40px sections, 1584px pills +- Mixed border styles: solid + dashed in the same interface +- Multi-layer shadow with inset highlight: `0px 1px 1px` + `-1px inset` + `-0.5px` + +## 2.

Visual Theme & Atmosphere + +ClickHouse's interface is a high-performance cockpit rendered in acid yellow-green on obsidian black — a design that screams "speed" before you read a single word. The entire experience lives in darkness: pure black backgrounds (`#000000`) with dark charcoal cards (`#414141` borders) creating a terminal-grade aesthetic where the only chromatic interruption is the signature neon yellow-green (`#faff69`) that slashes across CTAs, borders, and highlighted moments like a highlighter pen on a dark console. + +The typography is aggressively heavy — Inter at weight 900 (Black) for the hero headline at 96px creates text blocks that feel like they have physical mass. This "database for AI" site communicates raw power through visual weight: thick type, high-contrast neon accents, and performance stats displayed as oversized numbers. There's nothing subtle about ClickHouse's design, and that's entirely the point — it mirrors the product's promise of extreme speed and performance. + +What makes ClickHouse distinctive is the electrifying tension between the near-black canvas and the neon yellow-green accent. This color combination (`#faff69` on `#000000`) creates one of the highest-contrast pairings in any tech brand, making every CTA button, every highlighted card, and every accent border impossible to miss. Supporting this is a forest green (`#166534`) for secondary CTAs that adds depth to the action hierarchy without competing with the neon. + +**Key Characteristics:** +- Pure black canvas (#000000) with neon yellow-green (#faff69) accent — maximum contrast +- Extra-heavy display typography: Inter at weight 900 (Black) up to 96px +- Dark charcoal card system with #414141 borders at 80% opacity +- Forest green (#166534) secondary CTA buttons +- Performance stats as oversized display numbers +- Uppercase labels with wide letter-spacing (1.4px) for navigation structure +- Active/pressed state shifts text to pale yellow (#f4f692) +- All links hover to neon yellow-green — unified interactive signal +- Inset shadows on select elements creating "pressed into the surface" depth + +## 2. Color Palette & Roles + +### Primary +- **Neon Volt** (`#faff69`): The signature brand color — a vivid acid yellow-green that's the sole chromatic accent on the black canvas. Used for primary CTAs, accent borders, link hovers, and highlighted moments. +- **Forest Green** (`#166534`): Secondary CTA color — a deep, saturated green for "Get Started" and primary action buttons that need distinction from the neon. +- **Dark Forest** (`#14572f`): A darker green variant for borders and secondary accents. + +### Secondary & Accent +- **Pale Yellow** (`#f4f692`): Active/pressed state text color — a softer, more muted version of Neon Volt for state feedback. +- **Border Olive** (`#4f5100`): A dark olive-yellow for ghost button borders — the neon's muted sibling. +- **Olive Dark** (`#161600`): The darkest neon-tinted color for subtle brand text. + +### Surface & Background +- **Pure Black** (`#000000`): The primary page background — absolute black for maximum contrast. +- **Near Black** (`#141414`): Button backgrounds and slightly elevated dark surfaces. +- **Charcoal** (`#414141`): The primary border color at 80% opacity — the workhorse for card and container containment. +- **Deep Charcoal** (`#343434`): Darker border variant for subtle division lines. +- **Hover Gray** (`#3a3a3a`): Button hover state background — slightly lighter than Near Black. + +### Neutrals & Text +- **Pure White** (`#ffffff`): Primary text on dark surfaces. +- **Silver** (`#a0a0a0`): Secondary body text and muted content. +- **Mid Gray** (`#585858` at 28%): Subtle gray overlay for depth effects. +- **Border Gray** (`#e5e7eb`): Light border variant (used in rare light contexts). + +### Gradient System +- **None in the traditional sense.** ClickHouse uses flat color blocks and high-contrast borders. The "gradient" is the contrast itself — neon yellow-green against pure black creates a visual intensity that gradients would dilute. + +## 3.

Combined with 96px size, this creates text with a physical, almost architectural presence. +- **Full weight spectrum**: The system uses 400, 500, 600, 700, and 900 — covering the full gamut. Weight IS hierarchy. +- **Uppercase with maximum tracking**: Section overlines use 1.4px letter-spacing — wider than most systems — creating bold structural labels that stand out against the dense dark background. +- **Dual sans-serif**: Inter handles display and body; Basier handles feature section headings at 600 weight.

Visual Theme & Atmosphere + +Cohere's interface is a polished enterprise command deck — confident, clean, and designed to make AI feel like serious infrastructure rather than a consumer toy. The experience lives on a bright white canvas where content is organized into generously rounded cards (22px radius) that create an organic, cloud-like containment language. This is a site that speaks to CTOs and enterprise architects: professional without being cold, sophisticated without being intimidating. + +The design language bridges two worlds with a dual-typeface system: CohereText, a custom display serif with tight tracking, gives headlines the gravitas of a technology manifesto, while Unica77 Cohere Web handles all body and UI text with geometric Swiss precision.

Visual Theme & Atmosphere + +Composio's interface is a nocturnal command center — a dense, developer-focused darkness punctuated by electric cyan and deep cobalt signals. The entire experience is built on an almost-pure-black canvas (`#0f0f0f`) where content floats within barely-visible containment borders, creating the feeling of a high-tech control panel rather than a traditional marketing page. It's a site that whispers authority to developers who live in dark terminals. + +The visual language leans heavily into the aesthetic of code editors and terminal windows. JetBrains Mono appears alongside the geometric precision of abcDiatype, reinforcing the message that this is a tool built *by* developers *for* developers. Decorative elements are restrained but impactful — subtle cyan-blue gradient glows emanate from cards and sections like bioluminescent organisms in deep water, while hard-offset shadows (`4px 4px`) on select elements add a raw, brutalist edge that prevents the design from feeling sterile. + +What makes Composio distinctive is its tension between extreme minimalism and strategic bursts of luminous color. The site never shouts — headings use tight line-heights (0.87) that compress text into dense, authoritative blocks. Color is rationed like a rare resource: white text for primary content, semi-transparent white (`rgba(255,255,255,0.5-0.6)`) for secondary, and brand blue (`#0007cd`) or electric cyan (`#00ffff`) reserved exclusively for interactive moments and accent glows. + +**Key Characteristics:** +- Pitch-black canvas with near-invisible white-border containment (4-12% opacity) +- Dual-font identity: geometric sans-serif (abcDiatype) for content, monospace (JetBrains Mono) for technical credibility +- Ultra-tight heading line-heights (0.87-1.0) creating compressed, impactful text blocks +- Bioluminescent accent strategy — cyan and blue glows that feel like they're emitting light from within +- Hard-offset brutalist shadows (`4px 4px`) on select interactive elements +- Monochrome hierarchy with color used only at the highest-signal moments +- Developer-terminal aesthetic that bridges marketing and documentation + +## 2.

The hard-offset brutalist shadow is the signature — it breaks the sleek darkness with a raw, almost retro-computing feel. The soft diffuse shadow is reserved for truly floating elements. Most depth is communicated through border opacity gradations rather than shadows. + +### Decorative Depth +- **Cyan Glow Halos**: Radial gradient halos using Electric Cyan at low opacity behind feature cards and images.

Do's and Don'ts + +### Do +- Use Void Black (`#0f0f0f`) as the primary page background — never pure white for main surfaces +- Keep heading line-heights ultra-tight (0.87-1.0) for compressed, authoritative text blocks +- Use white-opacity borders (4-12%) for containment — they're more important than shadows here +- Reserve Electric Cyan (`#00ffff`) for high-signal moments only — CTAs, glows, interactive accents +- Pair abcDiatype with JetBrains Mono to reinforce the developer-tool identity +- Use the hard-offset shadow (`4px 4px`) intentionally on select elements for brutalist personality +- Keep button text dark (`oklch(0.145 0 0)`) even on the darkest backgrounds — buttons carry their own surface +- Layer opacity-based borders to create subtle depth without shadows +- Use uppercase + letter-spacing only for tiny overline labels (12px or smaller) + +### Don't +- Don't use bright backgrounds or light surfaces as primary containers +- Don't apply heavy shadows everywhere — depth comes from border opacity, not box-shadow +- Don't use Composio Cobalt (`#0007cd`) as a text color — it's too dark on dark and too saturated on light +- Don't increase heading line-heights beyond 1.2 — the compressed feel is core to the identity +- Don't use bold (700) weight for body or heading text — 400-500 is the ceiling +- Don't mix warm colors — the palette is strictly cool (blue, cyan, white, black) +- Don't use border-radius larger than 4px on content cards — the precision of near-square corners is intentional +- Don't place Electric Cyan at full opacity on large surfaces — it's an accent, used at 12% max for backgrounds +- Don't use decorative serif or handwritten fonts — the entire identity is geometric sans + monospace +- Don't skip the monospace font for technical content — JetBrains Mono is not decorative, it's a credibility signal + +## 8.

Visual Theme & Atmosphere + +Cursor's website is a study in warm minimalism meets code-editor elegance. The entire experience is built on a warm off-white canvas (`#f2f1ed`) with dark warm-brown text (`#26251e`) -- not pure black, not neutral gray, but a deeply warm near-black with a yellowish undertone that evokes old paper, ink, and craft. This warmth permeates every surface: backgrounds lean toward cream (`#e6e5e0`, `#ebeae5`), borders dissolve into transparent warm overlays using `oklab` color space, and even the error state (`#cf2d56`) carries warmth rather than clinical red. The result feels more like a premium print publication than a tech website. + +The custom CursorGothic font is the typographic signature -- a gothic sans-serif with aggressive negative letter-spacing at display sizes (-2.16px at 72px) that creates a compressed, engineered feel. As a secondary voice, the jjannon serif font (with OpenType `"cswh"` contextual swash alternates) provides literary counterpoint for body copy and editorial passages. The monospace voice comes from berkeleyMono, a refined coding font that connects the marketing site to Cursor's core identity as a code editor. This three-font system (gothic display, serif body, mono code) gives Cursor one of the most typographically rich palettes in developer tooling. + +The border system is particularly distinctive -- Cursor uses `oklab()` color space for border colors, applying warm brown at various alpha levels (0.1, 0.2, 0.55) to create borders that feel organic rather than mechanical. The signature border color `oklab(0.263084 -0.00230259 0.0124794 / 0.1)` is not a simple rgba value but a perceptually uniform color that maintains visual consistency across different backgrounds. + +**Key Characteristics:** +- CursorGothic with aggressive negative letter-spacing (-2.16px at 72px, -0.72px at 36px) for compressed display headings +- jjannon serif for body text with OpenType `"cswh"` (contextual swash alternates) +- berkeleyMono for code and technical labels +- Warm off-white background (`#f2f1ed`) instead of pure white -- the entire system is warm-shifted +- Primary text color `#26251e` (warm near-black with yellow undertone) +- Accent orange `#f54e00` for brand highlight and links +- oklab-space borders at various alpha levels for perceptually uniform edge treatment +- Pill-shaped elements with extreme radius (33.5M px, effectively full-pill) +- 8px base spacing system with fine-grained sub-8px increments (1.5px, 2px, 2.5px, 3px, 4px, 5px, 6px) + +## 2.

First, borders use perceptually uniform oklab color space rather than rgba, ensuring warm brown borders look consistent across different background tones. Second, elevation shadows use dramatically large blur values (28px, 70px) with moderate opacity (0.14, 0.1), creating a diffused, atmospheric lift rather than hard-edged drop shadows. Cards don't feel like they float above the page -- they feel like the page has gently opened a space for them. + +### Decorative Depth +- Warm cream surface variations create subtle tonal depth without shadows +- oklab borders at 10% and 20% create a spectrum of edge definition +- No harsh divider lines -- section separation through background tone shifts and spacing + +## 7.

Visual Theme & Atmosphere + +ElevenLabs' website is a study in restrained elegance — a near-white canvas (`#ffffff`, `#f5f5f5`) where typography and subtle shadows do all the heavy lifting. The design feels like a premium audio product brochure: clean, spacious, and confident enough to let the content speak (literally, given ElevenLabs makes voice AI). There's an almost Apple-like quality to the whitespace strategy, but warmer — the occasional warm stone tint (`#f5f2ef`, `#777169`) prevents the purity from feeling clinical. + +The typography system is built on a fascinating duality: Waldenburg at weight 300 (light) for display headings creates ethereal, whisper-thin titles that feel like sound waves rendered in type — delicate, precise, and surprisingly impactful at large sizes. This light-weight display approach is the design's signature — where most sites use bold headings to grab attention, ElevenLabs uses lightness to create intrigue. Inter handles all body and UI text with workmanlike reliability, using slight positive letter-spacing (0.14px–0.18px) that gives body text an airy, well-spaced quality. WaldenburgFH appears as a bold uppercase variant for specific button labels. + +What makes ElevenLabs distinctive is its multi-layered shadow system. Rather than simple box-shadows, elements use complex stacks: inset border-shadows (`rgba(0,0,0,0.075) 0px 0px 0px 0.5px inset`), outline shadows (`rgba(0,0,0,0.06) 0px 0px 0px 1px`), and soft elevation shadows (`rgba(0,0,0,0.04) 0px 4px 4px`) — all at remarkably low opacities. The result is a design where surfaces seem to barely exist, floating just above the page with the lightest possible touch. Pill-shaped buttons (9999px) with warm-tinted backgrounds (`rgba(245,242,239,0.8)`) and warm shadows (`rgba(78,50,23,0.04)`) add a tactile, physical quality. + +**Key Characteristics:** +- Near-white canvas with warm undertones (`#f5f5f5`, `#f5f2ef`) +- Waldenburg weight 300 (light) for display — ethereal, whisper-thin headings +- Inter with positive letter-spacing (0.14–0.18px) for body — airy readability +- Multi-layered shadow stacks at sub-0.1 opacity — surfaces barely exist +- Pill buttons (9999px) with warm stone-tinted backgrounds +- WaldenburgFH bold uppercase for specific CTA labels +- Warm shadow tints: `rgba(78, 50, 23, 0.04)` — shadows have color, not just darkness +- Geist Mono / ui-monospace for code snippets + +## 2.

Visual Theme & Atmosphere + +Expo's interface is a luminous, confidence-radiating developer platform built on the premise that tools for building apps should feel as polished as the apps themselves. The entire experience lives on a bright, airy canvas — a cool-tinted off-white (`#f0f0f3`) that gives the page a subtle technological coolness without the starkness of pure white. This is a site that breathes: enormous vertical spacing between sections creates a gallery-like pace where each feature gets its own "room." + +The design language is decisively monochromatic — pure black (`#000000`) headlines against the lightest possible backgrounds, with a spectrum of cool blue-grays (`#60646c`, `#b0b4ba`, `#555860`) handling all secondary communication. Color is almost entirely absent from the interface itself; when it appears, it's reserved for product screenshots, app icons, and the React universe illustration — making the actual content burst with life against the neutral canvas. + +What makes Expo distinctive is its pill-shaped geometry. Buttons, tabs, video containers, and even images use generously rounded or fully pill-shaped corners (24px–9999px), creating an organic, approachable feel that contradicts the typical sharp-edged developer tool aesthetic. Combined with tight letter-spacing on massive headlines (-1.6px to -3px at 64px), the result is a design that's simultaneously premium and friendly — like an Apple product page reimagined for developers. + +**Key Characteristics:** +- Luminous cool-white canvas (`#f0f0f3`) with gallery-like vertical spacing +- Strictly monochromatic: pure black headlines, cool blue-gray body text, no decorative color +- Pill-shaped geometry everywhere — buttons, tabs, containers, images (24px–9999px radius) +- Massive display headlines (64px) with extreme negative letter-spacing (-1.6px to -3px) +- Inter as the sole typeface, used at weights 400–900 for full expressive range +- Whisper-soft shadows that barely lift elements from the surface +- Product screenshots as the only source of color in the interface + +## 2. Color Palette & Roles + +### Primary +- **Expo Black** (`#000000`): The absolute anchor — used for primary headlines, CTA buttons, and the brand identity. Pure black on cool white creates maximum contrast without feeling aggressive. +- **Near Black** (`#1c2024`): The primary text color for body content — a barely perceptible blue-black that's softer than pure #000 for extended reading. + +### Secondary & Accent +- **Link Cobalt** (`#0d74ce`): The standard link color — a trustworthy, saturated blue that signals interactivity without competing with the monochrome hierarchy. +- **Legal Blue** (`#476cff`): A brighter, more saturated blue for legal/footer links — slightly more attention-grabbing than Link Cobalt. +- **Widget Sky** (`#47c2ff`): A light, friendly cyan-blue for widget branding elements — the brightest accent in the system. +- **Preview Purple** (`#8145b5`): A rich violet used for "preview" or beta feature indicators — creating clear visual distinction from standard content. + +### Surface & Background +- **Cloud Gray** (`#f0f0f3`): The primary page background — a cool off-white with the faintest blue-violet tint. Not warm, not sterile — precisely technological. +- **Pure White** (`#ffffff`): Card surfaces, button backgrounds, and elevated content containers. Creates a clear "lifted" distinction from Cloud Gray. +- **Widget Dark** (`#1a1a1a`): Dark surface for dark-theme widgets and overlay elements. +- **Banner Dark** (`#171717`): The darkest surface variant, used for promotional banners and high-contrast containers. + +### Neutrals & Text +- **Slate Gray** (`#60646c`): The workhorse secondary text color (305 instances). A cool blue-gray that's authoritative without being heavy. +- **Mid Slate** (`#555860`): Slightly darker than Slate, used for emphasized secondary text. +- **Silver** (`#b0b4ba`): Tertiary text, placeholders, and de-emphasized metadata. Comfortably readable but clearly receded. +- **Pewter** (`#999999`): Accordion icons and deeply de-emphasized UI elements in dark contexts. +- **Light Silver** (`#cccccc`): Arrow icons and decorative elements in dark contexts. +- **Dark Slate** (`#363a3f`): Borders on dark surfaces, switch tracks, and emphasized containment. +- **Charcoal** (`#333333`): Dark mode switch backgrounds and deep secondary surfaces. + +### Semantic & Accent +- **Warning Amber** (`#ab6400`): A warm, deep amber for warning states — deliberately not bright yellow, conveying seriousness. +- **Destructive Rose** (`#eb8e90`): A soft pink-coral for disabled destructive actions — gentler than typical red, reducing alarm fatigue. +- **Border Lavender** (`#e0e1e6`): Standard card/container borders — a cool lavender-gray that's visible without being heavy. +- **Input Border** (`#d9d9e0`): Button and form element borders — slightly warmer/darker than card borders for interactive elements. +- **Dark Focus Ring** (`#2547d0`): Deep blue for keyboard focus indicators in dark theme contexts. + +### Gradient System +- The design is notably **gradient-free** in the interface layer. Visual richness comes from product screenshots, the React universe illustration, and careful shadow layering rather than color gradients. This absence IS the design decision — gradients would undermine the clinical precision. + +## 3.

This gives the design a unified voice while still achieving dramatic contrast between whisper-light body text and thundering display headlines. +- **Extreme negative tracking at scale**: Headlines at 64px use -1.6px to -3px letter-spacing, creating ultra-dense text blocks that feel like logotypes. This aggressive compression is the signature typographic move. +- **Weight as hierarchy**: 700–900 for display, 600 for headings, 500 for emphasis, 400 for body. The jumps are decisive — no ambiguous in-between weights. +- **Consistent 1.40 body line-height**: Nearly all body and UI text shares 1.40 line-height, creating a rhythmic vertical consistency. + +## 4.

Visual Theme & Atmosphere + +Figma's interface is the design tool that designed itself — a masterclass in typographic sophistication where a custom variable font (figmaSans) modulates between razor-thin (weight 320) and bold (weight 700) with stops at unusual intermediates (330, 340, 450, 480, 540) that most type systems never explore. This granular weight control gives every text element a precisely calibrated visual weight, creating hierarchy through micro-differences rather than the blunt instrument of "regular vs bold." + +The page presents a fascinating duality: the interface chrome is strictly black-and-white (literally only `#000000` and `#ffffff` detected as colors), while the hero section and product showcases explode with vibrant multi-color gradients — electric greens, bright yellows, deep purples, hot pinks. This separation means the design system itself is colorless, treating the product's colorful output as the hero content. Figma's marketing page is essentially a white gallery wall displaying colorful art. + +What makes Figma distinctive beyond the variable font is its circle-and-pill geometry. Buttons use 50px radius (pill) or 50% (perfect circle for icon buttons), creating an organic, tool-palette-like feel. The dashed-outline focus indicator (`dashed 2px`) is a deliberate design choice that echoes selection handles in the Figma editor itself — the website's UI language references the product's UI language. + +**Key Characteristics:** +- Custom variable font (figmaSans) with unusual weight stops: 320, 330, 340, 450, 480, 540, 700 +- Strictly black-and-white interface chrome — color exists only in product content +- figmaMono for uppercase technical labels with wide letter-spacing +- Pill (50px) and circular (50%) button geometry +- Dashed focus outlines echoing Figma's editor selection handles +- Vibrant multi-color hero gradients (green, yellow, purple, pink) +- OpenType `"kern"` feature enabled globally +- Negative letter-spacing throughout — even body text at -0.14px to -0.26px + +## 2.

This creates hierarchy through subtle weight differences rather than dramatic jumps. The difference between 330 and 340 is nearly imperceptible but structurally significant. +- **Light as the base**: Most body text uses 320–340 (lighter than typical 400 "regular"), creating an ethereal, airy reading experience that matches the design-tool aesthetic. +- **Kern everywhere**: Every text element enables OpenType `"kern"` feature — kerning is not optional, it's structural. +- **Negative tracking by default**: Even body text uses -0.1px to -0.26px letter-spacing, creating universally tight text. Display text compresses further to -0.96px and -1.72px. +- **Mono for structure**: figmaMono in uppercase with positive letter-spacing (0.54px–0.6px) creates technical signpost labels. + +## 4.

The entire experience is drenched in pure black — not a warm charcoal or a cozy dark gray, but an absolute void (`#000000`) that makes every element, every screenshot, every typographic flourish feel like it's floating in deep space. This is a website that treats its own product UI as the hero art, embedding full-fidelity screenshots and interactive demos directly into the narrative flow. + +The typography is the signature move: GT Walsheim with aggressively tight letter-spacing (as extreme as -5.5px on 110px display text) creates headlines that feel compressed, kinetic, almost spring-loaded — like words under pressure that might expand at any moment. The transition to Inter for body text is seamless, with extensive OpenType feature usage (`cv01`, `cv05`, `cv09`, `cv11`, `ss03`, `ss07`) that gives even small text a refined, custom feel. Framer Blue (`#0099ff`) is deployed sparingly but decisively — as link color, border accents, and subtle ring shadows — creating a cold, electric throughline against the warm-less black. + +The overall effect is a nightclub for web designers: dark, precise, seductive, and unapologetically product-forward.

Visual Theme & Atmosphere + +HashiCorp's website is enterprise infrastructure made tangible — a design system that must communicate the complexity of cloud infrastructure management while remaining approachable. The visual language splits between two modes: a clean white light-mode for informational sections and a dramatic dark-mode (`#15181e`, `#0d0e12`) for hero areas and product showcases, creating a day/night duality that mirrors the "build in light, deploy in dark" developer workflow. + +The typography is anchored by a custom brand font (HashiCorp Sans, loaded as `__hashicorpSans_96f0ca`) that carries substantial weight — literally. Headings use 600–700 weights with tight line-heights (1.17–1.19), creating dense, authoritative text blocks that communicate enterprise confidence. The hero headline at 82px weight 600 with OpenType `"kern"` enabled is not decorative — it's infrastructure-grade typography. + +What distinguishes HashiCorp is its multi-product color system. Each product in the portfolio has its own brand color — Terraform purple (`#7b42bc`), Vault yellow (`#ffcf25`), Waypoint teal (`#14c6cb`), Vagrant blue (`#1868f2`) — and these colors appear throughout as accent tokens via a CSS custom property system (`--mds-color-*`). This creates a design system within a design system: the parent brand is black-and-white with blue accents, while each child product injects its own chromatic identity. + +The component system uses the `mds` (Markdown Design System) prefix, indicating a systematic, token-driven approach where colors, spacing, and states are all managed through CSS variables. Shadows are remarkably subtle — dual-layer micro-shadows using `rgba(97, 104, 117, 0.05)` that are nearly invisible but provide just enough depth to separate interactive surfaces from the background. + +**Key Characteristics:** +- Dual-mode: clean white sections + dramatic dark (`#15181e`) hero/product areas +- Custom HashiCorp Sans font with 600–700 weights and `"kern"` feature +- Multi-product color system via `--mds-color-*` CSS custom properties +- Product brand colors: Terraform purple, Vault yellow, Waypoint teal, Vagrant blue +- Uppercase letter-spaced captions (13px, weight 600, 1.3px letter-spacing) +- Micro-shadows: dual-layer at 0.05 opacity — depth through whisper, not shout +- Token-driven `mds` component system with semantic variable names +- Tight border radius: 2px–8px, nothing pill-shaped or circular +- System-ui fallback stack for secondary text + +## 2.

Visual Theme & Atmosphere + +IBM's website is the digital embodiment of enterprise authority built on the Carbon Design System — a design language so methodically structured it reads like an engineering specification rendered as a webpage. The page operates on a stark duality: a bright white (`#ffffff`) canvas with near-black (`#161616`) text, punctuated by a single, unwavering accent — IBM Blue 60 (`#0f62fe`). This isn't playful tech-startup minimalism; it's corporate precision distilled into pixels. Every element exists within Carbon's rigid 2x grid, every color maps to a semantic token, every spacing value snaps to the 8px base unit. + +The IBM Plex type family is the system's backbone. IBM Plex Sans at light weight (300) for display headlines creates an unexpectedly airy, almost delicate quality at large sizes — a deliberate counterpoint to IBM's corporate gravity. At body sizes, regular weight (400) with 0.16px letter-spacing on 14px captions introduces the meticulous micro-tracking that makes Carbon text feel engineered rather than designed. IBM Plex Mono serves code, data, and technical labels, completing the family trinity alongside the rarely-surfaced IBM Plex Serif. + +What defines IBM's visual identity beyond monochrome-plus-blue is the reliance on Carbon's component token system. Every interactive state maps to a CSS custom property prefixed with `--cds-` (Carbon Design System). Buttons don't have hardcoded colors; they reference `--cds-button-primary`, `--cds-button-primary-hover`, `--cds-button-primary-active`. This tokenized architecture means the entire visual layer is a thin skin over a deeply systematic foundation — the design equivalent of a well-typed API. + +**Key Characteristics:** +- IBM Plex Sans at weight 300 (Light) for display — corporate gravitas through typographic restraint +- IBM Plex Mono for code and technical content with consistent 0.16px letter-spacing at small sizes +- Single accent color: IBM Blue 60 (`#0f62fe`) — every interactive element, every CTA, every link +- Carbon token system (`--cds-*`) driving all semantic colors, enabling theme-switching at the variable level +- 8px spacing grid with strict adherence — no arbitrary values, everything aligns +- Flat, borderless cards on `#f4f4f4` Gray 10 surface — depth through background-color layering, not shadows +- Bottom-border inputs (not boxed) — the signature Carbon form pattern +- 0px border-radius on primary buttons — unapologetically rectangular, no softening + +## 2.

Sections are tightly packed compared to consumer design systems — this reflects IBM's enterprise DNA. +- **Background-color zoning**: Instead of massive padding between sections, IBM uses alternating background colors (white → gray 10 → white) to create visual separation with minimal vertical space. +- **Consistent 48px rhythm**: Major section transitions use 48px vertical spacing. Hero sections may use 80px–96px. + +### Border Radius Scale +- **0px**: Primary buttons, inputs, tiles, cards — the dominant treatment. Carbon is fundamentally rectangular. +- **2px**: Occasionally on small interactive elements (tags) +- **24px**: Tags/labels (pill shape — the sole rounded exception) +- **50%**: Avatar circles, icon containers + +## 6.

IBM achieves depth primarily through background-color layering — stacking surfaces of progressively darker grays rather than adding box-shadows. This creates a flat, print-inspired aesthetic where hierarchy is communicated through color value, not simulated light. Shadows are reserved exclusively for floating elements (dropdowns, tooltips, modals) where the element genuinely overlaps content. This restraint gives the rare shadow meaningful impact — when something floats in Carbon, it matters. + +## 7.

Visual Theme & Atmosphere + +Linear's website is a masterclass in dark-mode-first product design — a near-black canvas (`#08090a`) where content emerges from darkness like starlight. The overall impression is one of extreme precision engineering: every element exists in a carefully calibrated hierarchy of luminance, from barely-visible borders (`rgba(255,255,255,0.05)`) to soft, luminous text (`#f7f8f8`). This is not a dark theme applied to a light design — it is darkness as the native medium, where information density is managed through subtle gradations of white opacity rather than color variation. + +The typography system is built entirely on Inter Variable with OpenType features `"cv01"` and `"ss03"` enabled globally, giving the typeface a cleaner, more geometric character. Inter is used at a remarkable range of weights — from 300 (light body) through 510 (medium, Linear's signature weight) to 590 (semibold emphasis). The 510 weight is particularly distinctive: it sits between regular and medium, creating a subtle emphasis that doesn't shout. At display sizes (72px, 64px, 48px), Inter uses aggressive negative letter-spacing (-1.584px to -1.056px), creating compressed, authoritative headlines that feel engineered rather than designed. Berkeley Mono serves as the monospace companion for code and technical labels, with fallbacks to ui-monospace, SF Mono, and Menlo. + +The color system is almost entirely achromatic — dark backgrounds with white/gray text — punctuated by a single brand accent: Linear's signature indigo-violet (`#5e6ad2` for backgrounds, `#7170ff` for interactive accents). This accent color is used sparingly and intentionally, appearing only on CTAs, active states, and brand elements. The border system uses ultra-thin, semi-transparent white borders (`rgba(255,255,255,0.05)` to `rgba(255,255,255,0.08)`) that create structure without visual noise, like wireframes drawn in moonlight. + +**Key Characteristics:** +- Dark-mode-native: `#08090a` marketing background, `#0f1011` panel background, `#191a1b` elevated surfaces +- Inter Variable with `"cv01", "ss03"` globally — geometric alternates for a cleaner aesthetic +- Signature weight 510 (between regular and medium) for most UI text +- Aggressive negative letter-spacing at display sizes (-1.584px at 72px, -1.056px at 48px) +- Brand indigo-violet: `#5e6ad2` (bg) / `#7170ff` (accent) / `#828fff` (hover) — the only chromatic color in the system +- Semi-transparent white borders throughout: `rgba(255,255,255,0.05)` to `rgba(255,255,255,0.08)` +- Button backgrounds at near-zero opacity: `rgba(255,255,255,0.02)` to `rgba(255,255,255,0.05)` +- Multi-layered shadows with inset variants for depth on dark surfaces +- Radix UI primitives as the component foundation (6 detected primitives) +- Success green (`#27a644`, `#10b981`) used only for status indicators + +## 2.

The near-black background IS the whitespace, and content emerges from it. +- **Compressed headlines, expanded surroundings**: Display text at 72px with -1.584px tracking is dense and compressed, but sits within vast dark padding. The contrast between typographic density and spatial generosity creates tension. +- **Section isolation**: Each feature section is separated by generous vertical padding (80px+) with no visible dividers — the dark background provides natural separation. + +### Border Radius Scale +- Micro (2px): Inline badges, toolbar buttons, subtle tags +- Standard (4px): Small containers, list items +- Comfortable (6px): Buttons, inputs, functional elements +- Card (8px): Cards, dropdowns, popovers +- Panel (12px): Panels, featured cards, section containers +- Large (22px): Large panel elements +- Full Pill (9999px): Chips, filter pills, status tags +- Circle (50%): Icon buttons, avatars, status dots + +## 6.

Linear solves this by using semi-transparent white borders as the primary depth indicator. Elevation isn't communicated through shadow darkness but through background luminance steps — each level slightly increases the white opacity of the surface background (`0.02` → `0.04` → `0.05`), creating a subtle stacking effect. The inset shadow technique (`rgba(0,0,0,0.2) 0px 0px 12px 0px inset`) creates a unique "sunken" effect for recessed panels, adding dimensional depth that traditional dark themes lack. + +## 7.

Visual Theme & Atmosphere + +Lovable's website radiates warmth through restraint. The entire page sits on a creamy, parchment-toned background (`#f7f4ed`) that immediately separates it from the cold-white conventions of most developer tool sites. This isn't minimalism for minimalism's sake — it's a deliberate choice to feel approachable, almost analog, like a well-crafted notebook. The near-black text (`#1c1c1c`) against this warm cream creates a contrast ratio that's easy on the eyes while maintaining sharp readability. + +The custom Camera Plain Variable typeface is the system's secret weapon. Unlike geometric sans-serifs that signal "tech company," Camera Plain has a humanist warmth — slightly rounded terminals, organic curves, and a comfortable reading rhythm. At display sizes (48px–60px), weight 600 with aggressive negative letter-spacing (-0.9px to -1.5px) compresses headlines into confident, editorial statements. The font uses `ui-sans-serif, system-ui` as fallbacks, acknowledging that the custom typeface carries the brand personality. + +What makes Lovable's visual system distinctive is its opacity-driven depth model. Rather than using a traditional gray scale, the system modulates `#1c1c1c` at varying opacities (0.03, 0.04, 0.4, 0.82–0.83) to create a unified tonal range. Every shade of gray on the page is technically the same hue — just more or less transparent. This creates a visual coherence that's nearly impossible to achieve with arbitrary hex values. The border system follows suit: `1px solid #eceae4` for light divisions and `1px solid rgba(28, 28, 28, 0.4)` for stronger interactive boundaries. + +**Key Characteristics:** +- Warm parchment background (`#f7f4ed`) — not white, not beige, a deliberate cream that feels hand-selected +- Camera Plain Variable typeface with humanist warmth and editorial letter-spacing at display sizes +- Opacity-driven color system: all grays derived from `#1c1c1c` at varying transparency levels +- Inset shadow technique on buttons: `rgba(255,255,255,0.2) 0px 0.5px 0px 0px inset, rgba(0,0,0,0.2) 0px 0px 0px 0.5px inset` +- Warm neutral border palette: `#eceae4` for subtle, `rgba(28,28,28,0.4)` for interactive elements +- Full-pill radius (`9999px`) used extensively for action buttons and icon containers +- Focus state uses `rgba(0,0,0,0.1) 0px 4px 12px` shadow for soft, warm emphasis +- shadcn/ui + Radix UI component primitives with Tailwind CSS utility styling + +## 2.

Body text stays at normal tracking for comfortable reading. +- **Two weights, clear roles**: 400 (body/UI/links/buttons) and 600 (headings/emphasis).

The warm cream background makes these expanses feel cozy rather than empty. +- **Content-driven rhythm**: Tight internal spacing within cards (12–24px) contrasts with wide section gaps, creating a reading rhythm that alternates between focused content and visual rest. +- **Section separation**: Footer uses `1px solid #eceae4` border and 16px radius container. Sections defined by generous spacing rather than border lines. + +### Border Radius Scale +- Micro (4px): Small buttons, interactive elements +- Standard (6px): Buttons, inputs, navigation menu +- Comfortable (8px): Compact cards, divs +- Card (12px): Standard cards, image containers, templates +- Container (16px): Large containers, footer sections +- Full Pill (9999px): Action pills, icon buttons, toggles + +## 6.

Instead of floating cards with dramatic drop-shadows, the system relies on warm borders (`#eceae4`) against the cream surface to create gentle containment. The only notable shadow pattern is the inset shadow on dark buttons — a subtle multi-layer technique where a white highlight line sits at the top edge while a dark ring and soft drop handle the bottom. This creates a tactile, pressed-into-surface feeling rather than a hovering-above-surface feeling. The warm focus shadow (`rgba(0,0,0,0.1) 0px 4px 12px`) is deliberately diffused and large, creating a soft glow rather than a sharp outline. + +### Decorative Depth +- Hero: soft, warm multi-color gradient wash (pinks, oranges, blues) behind hero — atmospheric, barely visible +- Footer: gradient background with warm tones transitioning to the bottom +- No harsh section dividers — spacing and background warmth handle transitions + +## 7.

Visual Theme & Atmosphere + +MiniMax's website is a clean, product-showcase platform for a Chinese AI technology company that bridges consumer-friendly appeal with technical credibility. The design language is predominantly white-space-driven with a light, airy feel — pure white backgrounds (`#ffffff`) dominate, letting colorful product cards and AI model illustrations serve as the visual anchors. The overall aesthetic sits at the intersection of Apple's product marketing clarity and a playful, rounded design language that makes AI technology feel approachable. + +The typography system is notably multi-font: DM Sans serves as the primary UI workhorse, Outfit handles display headings with geometric elegance, Poppins appears for mid-tier headings, and Roboto handles data-heavy contexts. This variety reflects a brand in rapid growth — each font serves a distinct communicative purpose rather than competing for attention. The hero heading at 80px weight 500 in both DM Sans and Outfit with a tight 1.10 line-height creates a bold but not aggressive opening statement. + +What makes MiniMax distinctive is its pill-button geometry (9999px radius) for navigation and primary actions, combined with softer 8px–24px radiused cards for product showcases. The product cards themselves are richly colorful — vibrant gradients in pink, purple, orange, and blue — creating a "gallery of AI capabilities" feel. Against the white canvas, these colorful cards pop like app icons on a phone home screen, making each AI model/product feel like a self-contained creative tool. + +**Key Characteristics:** +- White-dominant layout with colorful product card accents +- Multi-font system: DM Sans (UI), Outfit (display), Poppins (mid-tier), Roboto (data) +- Pill buttons (9999px radius) for primary navigation and CTAs +- Generous rounded cards (20px–24px radius) for product showcases +- Brand blue spectrum: from `#1456f0` (brand-6) through `#3b82f6` (primary-500) to `#60a5fa` (light) +- Brand pink (`#ea5ec1`) as secondary accent +- Near-black text (`#222222`, `#18181b`) on white backgrounds +- Purple-tinted shadows (`rgba(44, 30, 116, 0.16)`) creating subtle brand-colored depth +- Dark footer section (`#181e25`) with product/company links + +## 2.

Visual Theme & Atmosphere + +Mintlify's website is a study in documentation-as-product design — a white, airy, information-rich surface that treats clarity as its highest aesthetic value. The page opens with a luminous white (`#ffffff`) background, near-black (`#0d0d0d`) text, and a signature green brand accent (`#18E299`) that signals freshness and intelligence without dominating the palette. The overall mood is calm, confident, and engineered for legibility — a design system that whispers "we care about your developer experience" in every pixel. + +The Inter font family carries the entire typographic load. At display sizes (40–64px), it uses tight negative letter-spacing (-0.8px to -1.28px) and semibold weight (600), creating headlines that feel focused and compressed like well-written documentation headers. Body text at 16–18px with 150% line-height provides generous reading comfort. Geist Mono appears exclusively for code and technical labels — uppercase, tracked-out, small — the voice of the terminal inside the marketing page. + +What distinguishes Mintlify from other documentation platforms is its atmospheric gradient hero. A soft, cloud-like green-to-white gradient wash behind the hero content creates a sense of ethereal intelligence — documentation that floats above the noise. Below the hero, the page settles into a disciplined alternation of white sections separated by subtle 5% opacity borders. Cards use generous padding (24px+) with large radii (16px–24px) and whisper-thin borders, creating containers that feel open rather than boxed. + +**Key Characteristics:** +- Inter with tight negative tracking at display sizes (-0.8px to -1.28px) — compressed yet readable +- Geist Mono for code labels: uppercase, 12px, tracked-out, the terminal voice +- Brand green (`#18E299`) used sparingly — CTAs, hover states, focus rings, and accent touches +- Atmospheric gradient hero with cloud-like green-white wash +- Ultra-round corners: 16px for containers, 24px for featured cards, full-round (9999px) for buttons and pills +- Subtle 5% opacity borders (`rgba(0,0,0,0.05)`) creating barely-there separation +- 8px base spacing system with generous section padding (48px–96px) +- Clean white canvas — no gray backgrounds, no color sections, depth through borders and whitespace alone + +## 2.

Mintlify sells documentation, so the marketing page itself demonstrates reading comfort. +- **Sections as chapters**: Each feature section is a self-contained unit with 48px–96px vertical padding, creating clear "chapter breaks." +- **Content density is low**: Unlike developer tools that pack the page, Mintlify uses 1–2 key messages per section with supporting imagery. + +### Border Radius Scale +- Small (4px): Inline code, small tags, tooltips +- Medium (8px): Nav buttons, transparent buttons, small containers +- Standard (16px): Cards, content containers, image wrappers +- Large (24px): Featured cards, hero containers, section panels +- Full Pill (9999px): Buttons, inputs, badges, pills — the signature shape + +## 6.

The depth system is almost entirely border-driven — ultra-subtle 5% opacity borders create separation without visual weight. When shadows appear, they're atmospheric whispers (`0.03 opacity, 2px blur, 4px spread`) that add the barest sense of lift. This restraint keeps the page feeling flat and paper-like — appropriate for a documentation company whose product is about clarity and readability. + +### Decorative Depth +- Hero gradient: atmospheric green-white cloud gradient behind hero content +- No background color alternation — white on white throughout +- Depth comes from border opacity variation (5% → 8%) and whitespace + +## 7.

Visual Theme & Atmosphere + +Mistral AI's interface is a sun-drenched landscape rendered in code — a warm, bold, unapologetically European design that trades the typical blue-screen AI aesthetic for golden amber, burnt orange, and the feeling of late-afternoon light in southern France. Every surface glows with warmth: backgrounds fade from pale cream to deep amber, shadows carry golden undertones (`rgba(127, 99, 21, ...)`), and the brand's signature orange (`#fa520f`) burns through the page like a signal fire. + +The design language is maximalist in its warmth but minimalist in its structure. Huge display headlines (82px) crash into the viewport with aggressive negative tracking (-2.05px), creating text blocks that feel like billboards or protest posters — declarations rather than descriptions. The typography uses Arial (likely a custom font with Arial as fallback) at extreme sizes, creating a raw, unadorned voice that says "we build frontier AI" with no decoration needed. + +What makes Mistral distinctive is the complete commitment to a warm color temperature. The signature "block" identity — a gradient system flowing from bright yellow (`#ffd900`) through amber (`#ffa110`) to burnt orange (`#fa520f`) — creates a visual identity that's immediately recognizable. Even the shadows are warm, using amber-tinted blacks instead of cool grays. Combined with dramatic landscape photography in golden tones, the design feels less like a tech company and more like a European luxury brand that happens to build language models. + +**Key Characteristics:** +- Golden-amber color universe: every tone from pale cream (#fffaeb) to burnt orange (#fa520f) +- Massive display typography (82px) with aggressive negative letter-spacing (-2.05px) +- Warm golden shadow system using amber-tinted rgba values +- The Mistral "M" block identity — a gradient from yellow to orange +- Dramatic landscape photography in warm golden tones +- Uppercase typography used strategically for section labels and CTAs +- Near-zero border-radius — sharp, architectural geometry +- French-European confidence: bold, warm, declarative + +## 2. Color Palette & Roles + +### Primary +- **Mistral Orange** (`#fa520f`): The core brand color — a vivid, saturated orange-red that anchors the entire identity. Used for primary emphasis, the brand block, and the highest-signal moments. +- **Mistral Flame** (`#fb6424`): A slightly warmer, lighter variant of the brand orange used for secondary brand moments and hover states. +- **Block Orange** (`#ff8105`): A pure orange used in the gradient block system — warmer and less red than Mistral Orange. + +### Secondary & Accent +- **Sunshine 900** (`#ff8a00`): Deep golden amber — the darkest sunshine tone, used for strong accent moments. +- **Sunshine 700** (`#ffa110`): Warm amber-gold — the core sunshine accent for backgrounds and interactive elements. +- **Sunshine 500** (`#ffb83e`): Medium golden — balanced warmth for mid-level emphasis. +- **Sunshine 300** (`#ffd06a`): Light golden — for subtle warm tints and secondary backgrounds. +- **Block Gold** (`#ffe295`): Pale gold — soft background accents and gentle warmth. +- **Bright Yellow** (`#ffd900`): The brightest tone in the gradient — used at the "top" of the block identity. + +### Surface & Background +- **Warm Ivory** (`#fffaeb`): The lightest page background — barely tinted with warmth, the foundation canvas. +- **Cream** (`#fff0c2`): The primary warm surface and secondary button background — noticeably golden. +- **Pure White** (`#ffffff`): Used for maximum contrast elements and popover surfaces. +- **Mistral Black** (`#1f1f1f`): The primary dark surface for buttons, text, and dark sections. +- **Accent Orange** (defined as `hsl(17, 96%, 52%)`): The functional accent color for interactive states. + +### Neutrals & Text +- **Mistral Black** (`#1f1f1f`): Primary text color and dark button backgrounds — a near-black that's warmer than pure #000. +- **Black Tint** (defined as `hsl(0, 0%, 24%)`): A medium dark gray for secondary text on light backgrounds. +- **Pure White** (`#ffffff`): Text on dark surfaces and CTA labels. + +### Semantic & Accent +- **Input Border** (defined as `hsl(240, 5.9%, 90%)`): A cool-tinted light gray for form borders — one of the few cool tones in the system. +- **White Overlay** (`oklab(1, 0, 0 / 0.088–0.1)`): Semi-transparent white for frosted glass effects and button overlays. + +### Gradient System +- **Mistral Block Gradient**: The signature identity — a multi-step gradient flowing through Yellow (`#ffd900`) → Gold (`#ffe295`) → Amber (`#ffa110`) → Orange (`#ff8105`) → Flame (`#fb6424`) → Mistral Orange (`#fa520f`). This gradient appears in the logo blocks, section backgrounds, and decorative elements. +- **Golden Landscape Wash**: Photography and backgrounds use warm amber overlays creating a consistent golden temperature across the page. +- **Warm Shadow Cascade**: Multi-layered golden shadows that build depth with amber-tinted transparency rather than gray. + +## 3. Typography Rules + +### Font Family +- **Primary**: Likely a custom font (Font Source detected) with `Arial` as fallback, and extended stack: `ui-sans-serif, system-ui, Apple Color Emoji, Segoe UI Emoji, Segoe UI Symbol, Noto Color Emoji` + +### Hierarchy + +| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes | +|------|------|------|--------|-------------|----------------|-------| +| Display / Hero | Arial (custom) | 82px (5.13rem) | 400 | 1.00 (tight) | -2.05px | Maximum impact, billboard scale | +| Section Heading | Arial (custom) | 56px (3.5rem) | 400 | 0.95 (ultra-tight) | normal | Feature section anchors | +| Sub-heading Large | Arial (custom) | 48px (3rem) | 400 | 0.95 (ultra-tight) | normal | Secondary section titles | +| Sub-heading | Arial (custom) | 32px (2rem) | 400 | 1.15 (tight) | normal | Card headings, feature names | +| Card Title | Arial (custom) | 30px (1.88rem) | 400 | 1.20 (tight) | normal | Mid-level headings | +| Feature Title | Arial (custom) | 24px (1.5rem) | 400 | 1.33 | normal | Small headings | +| Body / Button | Arial (custom) | 16px (1rem) | 400 | 1.50 | normal | Standard body, button text | +| Button Uppercase | Arial (custom) | 16px (1rem) | 400 | 1.50 | normal | Uppercase CTA labels | +| Caption / Link | Arial (custom) | 14px (0.88rem) | 400 | 1.43 | normal | Metadata, secondary links | + +### Principles +- **Single weight, maximum impact**: The entire system uses weight 400 (regular) — even at 82px. This creates a surprisingly elegant effect where the size alone carries authority without needing bold weight. +- **Ultra-tight at scale**: Line-heights of 0.95–1.00 at display sizes create text blocks where ascenders nearly touch descenders from the line above — creating dense, poster-like composition. +- **Aggressive tracking on display**: -2.05px letter-spacing at 82px compresses the hero text into a monolithic block. +- **Uppercase as emphasis**: Strategic `text-transform: uppercase` on button labels and section markers creates a formal, European signage quality. +- **No weight variation**: Unlike most systems that use 300–700 weight range, Mistral uses 400 everywhere. Hierarchy comes from size and color, never weight. + +## 4.

Depth & Elevation + +| Level | Treatment | Use | +|-------|-----------|-----| +| Flat (Level 0) | No shadow | Page backgrounds, text blocks | +| Golden Float (Level 1) | Multi-layer warm shadow (5 layers, 12%→0% opacity, amber-tinted) | Feature cards, product showcases, elevated content | + +**Shadow Philosophy**: Mistral uses a single but extraordinarily complex shadow — **five cascading layers** of amber-tinted shadow (`rgba(127, 99, 21, ...)`) that build from a close 16px offset to a distant 400px offset. The result is a rich, warm, "golden hour" lighting effect that makes elevated elements look like they're bathed in afternoon sunlight. This is the most distinctive shadow system in any major AI brand. + +## 7.

Visual Theme & Atmosphere + +MongoDB's website is a deep-forest-meets-terminal experience — a design system rooted in the darkest teal-black (`#001e2b`) that evokes both the density of a database and the depth of a forest canopy. Against this near-black canvas, a striking neon green (`#00ed64`) pulses as the brand accent — bright enough to feel electric, organic enough to feel alive. This isn't the cold neon of cyberpunk; it's the bioluminescent green of something growing in the dark. + +The typography system is architecturally ambitious: MongoDB Value Serif for massive hero headlines (96px) creates an editorial, authoritative presence — serif type at database-company scale is a bold choice that says "we're not just another tech company." Euclid Circular A handles the heavy lifting of body and UI text with an unusually wide weight range (300–700), while Source Code Pro serves as the code and label font with distinctive uppercase treatments featuring very wide letter-spacing (1px–3px). This three-font system creates a hierarchy that spans editorial elegance → geometric professionalism → engineering precision. + +What makes MongoDB distinctive is its dual-mode design: a dark hero/feature section world (`#001e2b` with neon green accents) and a light content world (white with teal-gray borders `#b8c4c2`). The transition between these modes creates dramatic contrast. The shadow system uses teal-tinted dark shadows (`rgba(0, 30, 43, 0.12)`) that maintain the forest-dark atmosphere even on light surfaces.

Visual Theme & Atmosphere + +Notion's website embodies the philosophy of the tool itself: a blank canvas that gets out of your way. The design system is built on warm neutrals rather than cold grays, creating a distinctly approachable minimalism that feels like quality paper rather than sterile glass. The page canvas is pure white (`#ffffff`) but the text isn't pure black -- it's a warm near-black (`rgba(0,0,0,0.95)`) that softens the reading experience imperceptibly. The warm gray scale (`#f6f5f4`, `#31302e`, `#615d59`, `#a39e98`) carries subtle yellow-brown undertones, giving the interface a tactile, almost analog warmth. + +The custom NotionInter font (a modified Inter) is the backbone of the system. At display sizes (64px), it uses aggressive negative letter-spacing (-2.125px), creating headlines that feel compressed and precise. The weight range is broader than typical systems: 400 for body, 500 for UI elements, 600 for semi-bold labels, and 700 for display headings. OpenType features `"lnum"` (lining numerals) and `"locl"` (localized forms) are enabled on larger text, adding typographic sophistication that rewards close reading. + +What makes Notion's visual language distinctive is its border philosophy. Rather than heavy borders or shadows, Notion uses ultra-thin `1px solid rgba(0,0,0,0.1)` borders -- borders that exist as whispers, barely perceptible division lines that create structure without weight. The shadow system is equally restrained: multi-layer stacks with cumulative opacity never exceeding 0.05, creating depth that's felt rather than seen. + +**Key Characteristics:** +- NotionInter (modified Inter) with negative letter-spacing at display sizes (-2.125px at 64px) +- Warm neutral palette: grays carry yellow-brown undertones (`#f6f5f4` warm white, `#31302e` warm dark) +- Near-black text via `rgba(0,0,0,0.95)` -- not pure black, creating micro-warmth +- Ultra-thin borders: `1px solid rgba(0,0,0,0.1)` throughout -- whisper-weight division +- Multi-layer shadow stacks with sub-0.05 opacity for barely-there depth +- Notion Blue (`#0075de`) as the singular accent color for CTAs and interactive elements +- Pill badges (9999px radius) with tinted blue backgrounds for status indicators +- 8px base spacing unit with an organic, non-rigid scale + +## 2. Color Palette & Roles + +### Primary +- **Notion Black** (`rgba(0,0,0,0.95)` / `#000000f2`): Primary text, headings, body copy. The 95% opacity softens pure black without sacrificing readability. +- **Pure White** (`#ffffff`): Page background, card surfaces, button text on blue. +- **Notion Blue** (`#0075de`): Primary CTA, link color, interactive accent -- the only saturated color in the core UI chrome. + +### Brand Secondary +- **Deep Navy** (`#213183`): Secondary brand color, used sparingly for emphasis and dark feature sections. +- **Active Blue** (`#005bab`): Button active/pressed state -- darker variant of Notion Blue. + +### Warm Neutral Scale +- **Warm White** (`#f6f5f4`): Background surface tint, section alternation, subtle card fill.

The compression creates density at headlines while maintaining readability at body sizes. +- **Four-weight system**: 400 (body/reading), 500 (UI/interactive), 600 (emphasis/navigation), 700 (headings/display). The broader weight range compared to most systems allows nuanced hierarchy. +- **Warm scaling**: Line height tightens as size increases -- 1.50 at body (16px), 1.23-1.27 at sub-headings, 1.00-1.04 at display. This creates denser, more impactful headlines. +- **Badge micro-tracking**: The 12px badge text uses positive letter-spacing (0.125px) -- the only positive tracking in the system, creating wider, more legible small text. + +## 4.

The 4-layer card shadow spans from 1.04px to 18px blur, creating a gradient of depth rather than a single hard shadow. The 5-layer deep shadow extends to 52px blur at 0.05 opacity, producing ambient occlusion that feels like natural light rather than computer-generated depth. This layered approach makes elements feel embedded in the page rather than floating above it. + +### Decorative Depth +- Hero section: decorative character illustrations (playful, hand-drawn style) +- Section alternation: white to warm white (`#f6f5f4`) background shifts +- No hard section borders -- separation comes from background color changes and spacing + +## 7.

Visual Theme & Atmosphere + +NVIDIA's website is a high-contrast, technology-forward experience that communicates raw computational power through design restraint. The page is built on a stark black (`#000000`) and white (`#ffffff`) foundation, punctuated by NVIDIA's signature green (`#76b900`) -- a color so specific it functions as a brand fingerprint. This is not the lush green of nature; it's the electric, lime-shifted green of GPU-rendered light, a color that sits between chartreuse and kelly green and immediately signals "NVIDIA" to anyone in technology. + +The custom NVIDIA-EMEA font family (with Arial and Helvetica fallbacks) creates a clean, industrial typographic voice. Headings at 36px bold with tight 1.25 line-height create dense, authoritative blocks of text. The font lacks the geometric playfulness of Silicon Valley sans-serifs -- it's European, pragmatic, and engineering-focused. Body text runs at 15-16px, comfortable for reading but not generous, maintaining the sense that screen real estate is optimized like GPU memory. + +What distinguishes NVIDIA's design from other dark-background tech sites is the disciplined use of the green accent. The `#76b900` appears in borders (`2px solid #76b900`), link underlines (`underline 2px rgb(118, 185, 0)`), and CTAs -- but never as backgrounds or large surface areas on the main content. The green is a signal, not a surface. Combined with a deep shadow system (`rgba(0, 0, 0, 0.3) 0px 0px 5px`) and minimal border radius (1-2px), the overall effect is of precision engineering hardware rendered in pixels. + +**Key Characteristics:** +- NVIDIA Green (`#76b900`) as pure accent -- borders, underlines, and interactive highlights only +- Black (`#000000`) dominant background with white (`#ffffff`) text on dark sections +- NVIDIA-EMEA custom font with Arial/Helvetica fallback -- industrial, European, clean +- Tight line-heights (1.25 for headings) creating dense, authoritative text blocks +- Minimal border radius (1-2px) -- sharp, engineered corners throughout +- Green-bordered buttons (`2px solid #76b900`) as primary interactive pattern +- Font Awesome 6 Pro/Sharp icon system at weight 900 for sharp iconography +- Multi-framework architecture (PrimeReact, Fluent UI, Element Plus) enabling rich interactive components + +## 2.

There is essentially one shadow value -- a 5px ambient blur at 30% opacity -- used sparingly for cards and modals. The primary depth signal is not shadow but _color contrast_: black backgrounds next to white sections, green borders on black surfaces. This creates hardware-like visual layering where depth comes from material difference, not simulated light. + +### Decorative Depth +- Green gradient washes behind hero content +- Dark-to-darker gradients (black to near-black) for section transitions +- No glassmorphism or blur effects -- clarity over atmosphere + +## 7.

Visual Theme & Atmosphere + +Ollama's interface is radical minimalism taken to its logical conclusion — a pure-white void where content floats without decoration, shadow, or color. The design philosophy mirrors the product itself: strip away everything unnecessary until only the essential tool remains. This is the digital equivalent of a Dieter Rams object — every pixel earns its place, and the absence of design IS the design. + +The entire page exists in pure grayscale. There is zero chromatic color in the interface — no brand blue, no accent green, no semantic red. The only colors that exist are shades between pure black (`#000000`) and pure white (`#ffffff`), creating a monochrome environment that lets the user's mental model of "open models" remain uncolored by brand opinion. The Ollama llama mascot, rendered in simple black line art, is the only illustration — and even it's monochrome. + +What makes Ollama distinctive is the combination of SF Pro Rounded (Apple's rounded system font) with an exclusively pill-shaped geometry (9999px radius on everything interactive).

The rounded font IS the brand expression. +- **Weight restraint**: Only two weights matter — 400 (regular) for body and 500 (medium) for headings. No bold, no light, no black weight. This extreme restraint reinforces the minimal philosophy. +- **Tight display, comfortable body**: Headlines compress to 1.0 line-height, while body text relaxes to 1.43–1.56. The contrast creates clear hierarchy without needing weight contrast. +- **Monospace for developer identity**: Code blocks and terminal commands appear throughout as primary content, using the system monospace stack. + +## 4.

Visual Theme & Atmosphere + +OpenCode's website embodies a terminal-native, monospace-first aesthetic that reflects its identity as an open source AI coding agent. The entire visual system is built on a stark dark-on-light contrast using a near-black background (`#201d1d`) with warm off-white text (`#fdfcfc`). This isn't a generic dark theme -- it's a warm, slightly reddish-brown dark that feels like a sophisticated terminal emulator rather than a cold IDE. The warm undertone in both the darks and lights (notice the subtle red channel in `#201d1d` -- rgb(32, 29, 29)) creates a cohesive, lived-in quality. + +Berkeley Mono is the sole typeface, establishing an unapologetic monospace identity. Every element -- headings, body text, buttons, navigation -- shares this single font family, creating a unified "everything is code" philosophy. The heading at 38px bold with 1.50 line-height is generous and readable, while body text at 16px with weight 500 provides a slightly heavier-than-normal reading weight that enhances legibility on screen. The monospace grid naturally enforces alignment and rhythm across the layout. + +The color system is deliberately minimal. The primary palette consists of just three functional tones: the warm near-black (`#201d1d`), a medium warm gray (`#9a9898`), and a bright off-white (`#fdfcfc`). Semantic colors borrow from the Apple HIG palette -- blue accent (`#007aff`), red danger (`#ff3b30`), green success (`#30d158`), orange warning (`#ff9f0a`) -- giving the interface familiar, trustworthy signal colors without adding brand complexity. Borders use a subtle warm transparency (`rgba(15, 0, 0, 0.12)`) that ties into the warm undertone of the entire system. + +**Key Characteristics:** +- Berkeley Mono as the sole typeface -- monospace everywhere, no sans-serif or serif voices +- Warm near-black primary (`#201d1d`) with reddish-brown undertone, not pure black +- Off-white text (`#fdfcfc`) with warm tint, not pure white +- Minimal 4px border radius throughout -- sharp, utilitarian corners +- 8px base spacing system scaling up to 96px +- Apple HIG-inspired semantic colors (blue, red, green, orange) +- Transparent warm borders using `rgba(15, 0, 0, 0.12)` +- Email input with generous 20px padding and 6px radius -- the most generous component radius +- Single button variant: dark background, light text, tight vertical padding (4px 20px) +- Underlined links as default link style, reinforcing the text-centric identity + +## 2. Color Palette & Roles + +### Primary +- **OpenCode Dark** (`#201d1d`): Primary background, button fills, link text. A warm near-black with subtle reddish-brown warmth -- rgb(32, 29, 29). +- **OpenCode Light** (`#fdfcfc`): Primary text on dark surfaces, button text. A barely-warm off-white that avoids clinical pure white. +- **Mid Gray** (`#9a9898`): Secondary text, muted links. A neutral warm gray that bridges dark and light. + +### Secondary +- **Dark Surface** (`#302c2c`): Slightly lighter than primary dark, used for elevated surfaces and subtle differentiation. +- **Border Gray** (`#646262`): Stronger borders, outline rings on interactive elements. +- **Light Surface** (`#f1eeee`): Light mode surface, subtle background variation. + +### Accent +- **Accent Blue** (`#007aff`): Primary accent, links, interactive highlights. Apple system blue. +- **Accent Blue Hover** (`#0056b3`): Darker blue for hover states. +- **Accent Blue Active** (`#004085`): Deepest blue for pressed/active states. + +### Semantic +- **Danger Red** (`#ff3b30`): Error states, destructive actions. Apple system red. +- **Danger Hover** (`#d70015`): Darker red for hover on danger elements. +- **Danger Active** (`#a50011`): Deepest red for pressed danger states. +- **Success Green** (`#30d158`): Success states, positive feedback. Apple system green. +- **Warning Orange** (`#ff9f0a`): Warning states, caution signals. Apple system orange. +- **Warning Hover** (`#cc7f08`): Darker orange for hover on warning elements. +- **Warning Active** (`#995f06`): Deepest orange for pressed warning states. + +### Text Scale +- **Text Muted** (`#6e6e73`): Muted labels, disabled text, placeholder content. +- **Text Secondary** (`#424245`): Secondary text on light backgrounds, captions. + +### Border +- **Border Warm** (`rgba(15, 0, 0, 0.12)`): Primary border color, warm transparent black with red tint. +- **Border Tab** (`#9a9898`): Tab underline border, 2px solid bottom. +- **Border Outline** (`#646262`): 1px solid outline border for containers. + +## 3. Typography Rules + +### Font Family +- **Universal**: `Berkeley Mono`, with fallbacks: `IBM Plex Mono, ui-monospace, SFMono-Regular, Menlo, Monaco, Consolas, Liberation Mono, Courier New, monospace` + +### Hierarchy + +| Role | Size | Weight | Line Height | Notes | +|------|------|--------|-------------|-------| +| Heading 1 | 38px (2.38rem) | 700 | 1.50 | Hero headlines, page titles | +| Heading 2 | 16px (1.00rem) | 700 | 1.50 | Section titles, bold emphasis | +| Body | 16px (1.00rem) | 400 | 1.50 | Standard body text, paragraphs | +| Body Medium | 16px (1.00rem) | 500 | 1.50 | Links, button text, nav items | +| Body Tight | 16px (1.00rem) | 500 | 1.00 (tight) | Compact labels, tab items | +| Caption | 14px (0.88rem) | 400 | 2.00 (relaxed) | Footnotes, metadata, small labels | + +### Principles +- **One font, one voice**: Berkeley Mono is used exclusively. There is no typographic variation between display, body, and code -- everything speaks in the same monospace register. Hierarchy is achieved through size and weight alone. +- **Weight as hierarchy**: 700 for headings, 500 for interactive/medium emphasis, 400 for body text. Three weight levels create the entire hierarchy. +- **Generous line-height**: 1.50 as the standard line-height gives text room to breathe within the monospace grid. The relaxed 2.00 line-height on captions creates clear visual separation. +- **Tight for interaction**: Interactive elements (tabs, compact labels) use 1.00 line-height for dense, clickable targets. + +## 4.

Line-heights of 1.50 and 2.00 maintain consistent rhythm. +- **Narrow and focused**: Content is constrained to a narrow column, creating generous side margins that focus attention on the text. +- **Sections through spacing**: No decorative dividers. Sections are separated by generous vertical spacing (48-96px) rather than borders or background changes. + +### Border Radius Scale +- Micro (4px): Default for all elements -- buttons, containers, badges +- Input (6px): Form inputs get slightly more roundness +- The entire system uses just two radius values, reinforcing the utilitarian aesthetic + +## 6. Depth & Elevation + +| Level | Treatment | Use | +|-------|-----------|-----| +| Flat (Level 0) | No shadow, no border | Default state for most elements | +| Border Subtle (Level 1) | `1px solid rgba(15, 0, 0, 0.12)` | Section dividers, input borders, horizontal rules | +| Border Tab (Level 2) | `2px solid #9a9898` bottom only | Active tab indicator | +| Border Outline (Level 3) | `1px solid #646262` | Container outlines, elevated elements | + +**Shadow Philosophy**: OpenCode's depth system is intentionally flat. There are no box-shadows in the extracted tokens -- zero shadow values were detected. Depth is communicated exclusively through border treatments and background color shifts. This flatness is consistent with the terminal aesthetic: terminals don't have shadows, and neither does OpenCode. The three border levels (transparent warm, tab indicator, solid outline) create sufficient visual hierarchy without any elevation illusion. + +### Decorative Depth +- Background color shifts between `#201d1d` and `#302c2c` create subtle surface differentiation +- Transparent borders at 12% opacity provide barely-visible structure +- The warm reddish tint in border colors (`rgba(15, 0, 0, 0.12)`) ties borders to the overall warm dark palette +- No gradients, no blurs, no ambient effects -- pure flat terminal aesthetic + +## 7. Interaction & Motion + +### Hover States +- Links: color shift from default to accent blue (`#007aff`) or underline style change +- Buttons: subtle background lightening or border emphasis +- Accent blue provides a three-stage hover sequence: `#007aff` → `#0056b3` → `#004085` (default → hover → active) +- Danger red: `#ff3b30` → `#d70015` → `#a50011` +- Warning orange: `#ff9f0a` → `#cc7f08` → `#995f06` + +### Focus States +- Border-based focus: increased border opacity or solid border color +- No shadow-based focus rings -- consistent with the flat, no-shadow aesthetic +- Keyboard focus likely uses outline or border color shift to accent blue + +### Transitions +- Minimal transitions expected -- terminal-inspired interfaces favor instant state changes +- Color transitions: 100-150ms for subtle state feedback +- No scale, rotate, or complex transform animations + +## 8.

Borders use `rgba(15, 0, 0, 0.12)` -- a warm transparent dark, not neutral gray. This ties borders to the warm palette. +8. Spacing follows an 8px grid: 8, 16, 24, 32, 40, 48, 64, 80, 96px.

Visual Theme & Atmosphere + +Pinterest's website is a warm, inspiration-driven canvas that treats visual discovery like a lifestyle magazine. The design operates on a soft, slightly warm white background with Pinterest Red (`#e60023`) as the singular, bold brand accent. Unlike the cool blues of most tech platforms, Pinterest's neutral scale has a distinctly warm undertone — grays lean toward olive/sand (`#91918c`, `#62625b`, `#e5e5e0`) rather than cool steel, creating a cozy, craft-like atmosphere that invites browsing. + +The typography uses Pin Sans — a custom proprietary font with a broad fallback stack including Japanese fonts, reflecting Pinterest's global reach. At display scale (70px, weight 600), Pin Sans creates large, inviting headlines. At smaller sizes, the system is compact: buttons at 12px, captions at 12–14px. The CSS variable naming system (`--comp-*`, `--sema-*`, `--base-*`) reveals a sophisticated three-tier design token architecture: component-level, semantic-level, and base-level tokens. + +What distinguishes Pinterest is its generous border-radius system (12px–40px, plus 50% for circles) and warm-tinted button backgrounds. The secondary button (`#e5e5e0`) has a distinctly warm, sand-like tone rather than cold gray. The primary red button uses 16px radius — rounded but not pill-shaped. Combined with warm badge backgrounds (`hsla(60,20%,98%,.5)` — a subtle yellow-warm wash) and photography-dominant layouts, the result is a design that feels handcrafted and personal, not corporate and sterile. + +**Key Characteristics:** +- Warm white canvas with olive/sand-toned neutrals — cozy, not clinical +- Pinterest Red (`#e60023`) as singular bold accent — never subtle, always confident +- Pin Sans custom font with global fallback stack (including CJK) +- Three-tier token architecture: `--comp-*` / `--sema-*` / `--base-*` +- Warm secondary surfaces: sand gray (`#e5e5e0`), warm badge (`hsla(60,20%,98%,.5)`) +- Generous border-radius: 16px standard, up to 40px for large containers +- Photography-first content — pins/images are the primary visual element +- Dark near-purple text (`#211922`) — warm, with a hint of plum + +## 2.

Visual Theme & Atmosphere + +Raycast's marketing site feels like the dark interior of a precision instrument — a Swiss watch case carved from obsidian. The background isn't just dark, it's an almost-black blue-tint (`#07080a`) that creates a sense of being inside a macOS native application rather than a website. Every surface, every border, every shadow is calibrated to evoke the feeling of a high-performance desktop utility: fast, minimal, trustworthy. + +The signature move is the layered shadow system borrowed from macOS window chrome: multi-layer box-shadows with inset highlights that simulate physical depth, as if cards and buttons are actual pressed or raised glass elements on a dark desk. Combined with Raycast Red (`#FF6363`) — deployed almost exclusively in the hero's iconic diagonal stripe pattern — the palette creates a brand that reads as "powerful tool with personality." The red doesn't dominate; it punctuates. + +Inter is used everywhere — headings, body, buttons, captions — with extensive OpenType features (`calt`, `kern`, `liga`, `ss03`) creating a consistent, readable typographic voice. The positive letter-spacing (0.2px–0.4px on body text) is unusual for a dark UI and gives the text an airy, breathable quality that counterbalances the dense, dark surfaces. GeistMono appears for code elements, reinforcing the developer-tool identity. + +**Key Characteristics:** +- Near-black blue-tinted background (`#07080a`) — not pure black, subtly blue-shifted +- macOS-native shadow system with multi-layer inset highlights simulating physical depth +- Raycast Red (`#FF6363`) as a punctuation color — hero stripes, not pervasive +- Inter with positive letter-spacing (0.2px) for an airy, readable dark-mode experience +- Radix UI component primitives powering the interaction layer +- Subtle rgba white borders (0.06–0.1 opacity) for containment on dark surfaces +- Keyboard shortcut styling with gradient key caps and heavy shadows + +## 2.

Visual Theme & Atmosphere + +Replicate's interface is a developer playground crackling with creative energy — a bold, high-contrast design that feels more like a music festival poster than a typical API platform. The hero section explodes with a vibrant orange-red-magenta gradient that immediately signals "this is where AI models come alive," while the body of the page grounds itself in a clean white canvas where code snippets and model galleries take center stage. + +The design personality is defined by two extreme choices: **massive display typography** (up to 128px) using the custom rb-freigeist-neue face, and **exclusively pill-shaped geometry** (9999px radius on everything). The display font is thick, bold, and confident — its heavy weight at enormous sizes creates text that feels like it's shouting with joy rather than whispering authority. Combined with basier-square for body text (a clean geometric sans) and JetBrains Mono for code, the system serves developers who want power and playfulness in equal measure. + +What makes Replicate distinctive is its community-powered energy. The model gallery with AI-generated images, the dotted-underline links, the green status badges, and the "Imagine what you can build" closing manifesto all create a space that feels alive and participatory — not a corporate product page but a launchpad for creative developers. + +**Key Characteristics:** +- Explosive orange-red-magenta gradient hero (#ea2804 brand anchor) +- Massive display typography (128px) in heavy rb-freigeist-neue +- Exclusively pill-shaped geometry: 9999px radius on EVERYTHING +- High-contrast black (#202020) and white palette with red brand accent +- Developer-community energy: model galleries, code examples, dotted-underline links +- Green status badges (#2b9a66) for live/operational indicators +- Bold/heavy font weights (600-700) creating maximum typographic impact +- Playful closing manifesto: "Imagine what you can build." + +## 2.

Visual Theme & Atmosphere + +Resend's website is a dark, cinematic canvas that treats email infrastructure like a luxury product. The entire page is draped in pure black (`#000000`) with text that glows in near-white (`#f0f0f0`), creating a theater-like experience where content performs on a void stage. This isn't the typical developer-tool darkness — it's the controlled darkness of a photography gallery, where every element is lit with intention and nothing competes for attention. + +The typography system is the star of the show. Three carefully chosen typefaces create a hierarchy that feels both editorial and technical: Domaine Display (a Klim Type Foundry serif) appears at massive 96px for hero headlines with barely-there line-height (1.00) and negative tracking (-0.96px), creating display text that feels like a magazine cover. ABC Favorit (by Dinamo) handles section headings with an even more aggressive letter-spacing (-2.8px at 56px), giving a compressed, engineered quality to mid-tier text. Inter takes over for body and UI, providing the clean readability that lets the display fonts shine. Commit Mono rounds out the family for code blocks. + +What makes Resend distinctive is its icy, blue-tinted border system. Instead of neutral gray borders, Resend uses `rgba(214, 235, 253, 0.19)` — a frosty, slightly blue-tinted line at 19% opacity that gives every container and divider a cold, crystalline quality against the black background.

The display type feels compressed, urgent, and designed — like a magazine masthead. +- **Positive tracking on nav**: ABC Favorit nav links use +0.35px letter-spacing — the only positive tracking in the system. This creates airy, spaced-out navigation text that contrasts with the compressed headings. +- **OpenType as identity**: The `"ss01"`, `"ss03"`, `"ss04"`, `"ss11"` stylistic sets are enabled on all ABC Favorit and Domaine text, activating alternate glyphs that give Resend's typography its unique character. +- **Commit Mono as design element**: The monospace font isn't hidden in code blocks — it's used prominently for code examples and technical content, treated as a first-class visual element. + +## 4.

Generous vertical spacing (80px–120px+) between sections creates a scroll-through-darkness experience where each section emerges like a scene. +- **Tight content, vast surrounds**: Text blocks and cards are compact internally, but float in vast dark space — creating isolated "islands" of content. +- **Typography-led rhythm**: The massive display fonts (96px) create their own vertical rhythm — each headline is a visual event that anchors the surrounding space. + +### Border Radius Scale +- Sharp (4px): Buttons (ghost), inputs, small interactive elements +- Subtle (6px): Menu panels, navigation items +- Standard (8px): Tabs, content blocks +- Comfortable (10px): Accent elements +- Card (12px): Clipboard buttons, medium containers +- Large (16px): Feature cards, images, main buttons +- Section (24px): Large panels, section containers +- Pill (9999px): Primary CTAs, tags, badges + +## 6.

On a pure black background, traditional shadows are invisible — you can't cast a shadow into the void. Instead, Resend creates depth through its signature frost borders (`rgba(214, 235, 253, 0.19)`) — thin, icy blue-tinted lines that catch light against the darkness. This creates a "glass panel floating in space" aesthetic where borders are the primary depth mechanism. + +### Decorative Depth +- Subtle warm gradient glows behind hero content (orange/amber tints) +- Product screenshots create visual depth through their own internal UI +- No gradient backgrounds — depth comes from border luminance and content contrast + +## 7.

Visual Theme & Atmosphere + +Revolut's website is fintech confidence distilled into pixels — a design system that communicates "your money is in capable hands" through massive typography, generous whitespace, and a disciplined neutral palette. The visual language is built on Aeonik Pro, a geometric grotesque that creates billboard-scale headlines at 136px with weight 500 and aggressive negative tracking (-2.72px). This isn't subtle branding; it's fintech at stadium scale. + +The color system is built on a comprehensive `--rui-*` (Revolut UI) token architecture with semantic naming for every state: danger (`#e23b4a`), warning (`#ec7e00`), teal (`#00a87e`), blue (`#494fdf`), deep-pink (`#e61e49`), and more. But the marketing surface itself is remarkably restrained — near-black (`#191c1f`) and pure white (`#ffffff`) dominate, with the colorful semantic tokens reserved for the product interface, not the marketing page. + +What distinguishes Revolut is its pill-everything button system. Every button uses 9999px radius — primary dark (`#191c1f`), secondary light (`#f4f4f4`), outlined (`transparent + 2px solid`), and ghost on dark (`rgba(244,244,244,0.1) + 2px solid`). The padding is generous (14px 32px–34px), creating large, confident touch targets. Combined with Inter for body text at various weights and positive letter-spacing (0.16px–0.24px), the result is a design that feels both premium and accessible — banking for the modern era. + +**Key Characteristics:** +- Aeonik Pro display at 136px weight 500 — billboard-scale fintech headlines +- Near-black (`#191c1f`) + white binary with comprehensive `--rui-*` semantic tokens +- Universal pill buttons (9999px radius) with generous padding (14px 32px) +- Inter for body text with positive letter-spacing (0.16px–0.24px) +- Rich semantic color system: blue, teal, pink, yellow, green, brown, danger, warning +- Zero shadows detected — depth through color contrast only +- Tight display line-heights (1.00) with relaxed body (1.50–1.56) + +## 2.

Visual Theme & Atmosphere + +Runway's interface is a cinematic reel brought to life as a website — a dark, editorial, film-production-grade design where full-bleed photography and video ARE the primary UI elements. This is not a typical tech product page; it's a visual manifesto for AI-powered creativity. Every section feels like a frame from a film: dramatic lighting, sweeping landscapes, and intimate human moments captured in high-quality imagery that dominates the viewport. + +The design language is built on a single typeface — abcNormal — a clean, geometric sans-serif that handles everything from 48px display headlines to 11px uppercase labels. This single-font commitment creates an extreme typographic uniformity that lets the visual content speak louder than the text. Headlines use tight line-heights (1.0) with negative letter-spacing (-0.9px to -1.2px), creating compressed text blocks that feel like film titles rather than marketing copy. + +What makes Runway distinctive is its complete commitment to visual content as design. Rather than illustrating features with icons or diagrams, Runway shows actual AI-generated and AI-enhanced imagery — cars driving through cinematic landscapes, artistic portraits, architectural renders. The interface itself retreats into near-invisibility: minimal borders, zero shadows, subtle cool-gray text, and a dark palette that puts maximum focus on the photography. + +**Key Characteristics:** +- Cinematic full-bleed photography and video as primary UI elements +- Single typeface system: abcNormal for everything from display to micro labels +- Dark-dominant palette with cool-toned neutrals (#767d88, #7d848e) +- Zero shadows, minimal borders — the interface is intentionally invisible +- Tight display typography (line-height 1.0) with negative tracking (-0.9px to -1.2px) +- Uppercase labels with positive letter-spacing for navigational structure +- Weight 450 (unusual intermediate) for small uppercase text — precision craft +- Editorial magazine layout with mixed-size image grids + +## 2.

The design achieves variety through size, weight, case, and letter-spacing rather than font-family switching. +- **Tight everywhere**: Nearly every size uses line-height 1.0–1.30 — even body text is relatively compressed. This creates a dense, editorial feel. +- **Weight 450 — the precision detail**: Some small uppercase labels use weight 450, an uncommon intermediate between regular (400) and medium (500). This micro-craft signals typographic sophistication. +- **Negative tracking as default**: Even body text uses -0.16px to -0.26px letter-spacing, keeping everything slightly tighter than default. +- **Uppercase as structure**: Labels at 14px and 11px use `text-transform: uppercase` with positive letter-spacing (0.35px) to create navigational signposts that contrast with the tight lowercase text. + +## 4.

Visual Theme & Atmosphere + +Sanity's website is a developer-content platform rendered as a nocturnal command center -- dark, precise, and deeply structured. The entire experience sits on a near-black canvas (`#0b0b0b`) that reads less like a "dark mode toggle" and more like the natural state of a tool built for people who live in terminals. Where most CMS marketing pages reach for friendly pastels and soft illustration, Sanity leans into the gravity of its own product: structured content deserves a structured stage. + +The signature typographic voice is waldenburgNormal -- a distinctive, slightly geometric sans-serif with tight negative letter-spacing (-0.32px to -4.48px at display sizes) that gives headlines a compressed, engineered quality. At 112px hero scale with -4.48px tracking, the type feels almost machined -- like precision-cut steel letterforms. This is paired with IBM Plex Mono for code and technical labels, creating a dual-register voice: editorial authority meets developer credibility. + +What makes Sanity distinctive is the interplay between its monochromatic dark palette and vivid, saturated accent punctuation. The neutral scale runs from pure black through a tightly controlled gray ramp (`#0b0b0b` -> `#212121` -> `#353535` -> `#797979` -> `#b9b9b9` -> `#ededed` -> `#ffffff`) with no warm or cool bias -- just pure, achromatic precision. Against this disciplined backdrop, a neon green accent (display-p3 green) and electric blue (`#0052ef`) land with the impact of signal lights in a dark control room.

Within sections, spacing is tighter (16-32px), creating dense information clusters separated by generous voids. This rhythm gives the page a "slides" quality -- each section feels like its own focused frame. + +### Border Radius Scale + +| Token | Value | Usage | +|-------|-------|-------| +| radius-xs | 3px | Inputs, textareas, subtle rounding | +| radius-sm | 4-5px | Secondary buttons, small cards, tags | +| radius-md | 6px | Standard cards, containers | +| radius-lg | 12px | Large cards, feature containers, forms | +| radius-pill | 99999px | Primary buttons, badges, nav pills | + +## 6. Depth & Elevation + +### Shadow System + +| Level | Value | Usage | +|-------|-------|-------| +| Level 0 (Flat) | none | Default state for most elements -- dark surfaces create depth through color alone | +| Level 1 (Subtle) | 0px 0px 0px 1px `#212121` | Border-like shadow for minimal containment without visible borders | +| Level 2 (Focus) | 0 0 0 2px `var(--color-blue-500)` | Focus ring for inputs and interactive elements | +| Level 3 (Overlay) | Backdrop blur + semi-transparent dark | Navigation overlay, modal backgrounds | + +### Depth Philosophy +Sanity's depth system is almost entirely **colorimetric** rather than shadow-based. Elevation is communicated through surface color shifts: `#0b0b0b` (ground) -> `#212121` (elevated) -> `#353535` (prominent) -> `#ffffff` (inverted/highest). This approach is native to dark interfaces where traditional drop shadows would be invisible. The few shadows that exist are ring-based (0px 0px 0px Npx) or blur-based (backdrop-filter) rather than offset shadows, maintaining the flat, precision-engineered aesthetic. + +Border-based containment (1px solid `#212121` or `#353535`) serves as the primary spatial separator, with the border darkness calibrated to be visible but not dominant. The system avoids "floating card" aesthetics -- everything feels mounted to the surface rather than hovering above it. + +## 7. Do's and Don'ts + +### Do +- Use the achromatic gray scale as the foundation -- maintain pure neutral discipline with no warm/cool tinting +- Apply Electric Blue (`#0052ef`) consistently as the universal hover/active state across all interactive elements +- Use extreme negative letter-spacing (-2px to -4.48px) on display headings 48px and above +- Keep primary CTAs as full-pill shapes (99999px radius) with the coral-red (`#f36458`) +- Use IBM Plex Mono uppercase for technical labels, tags, and system metadata +- Communicate depth through surface color (dark-to-light) rather than shadows +- Maintain generous vertical section spacing (64-120px) on the dark canvas +- Use `"cv01", "cv11", "cv12", "cv13", "ss07"` OpenType features for display typography + +### Don't +- Don't introduce warm or cool color tints to the neutral scale -- Sanity's grays are pure achromatic +- Don't use drop shadows for elevation -- dark interfaces demand colorimetric depth +- Don't apply border-radius between 13px and 99998px -- the system jumps from 12px (large card) directly to pill (99999px) +- Don't mix the coral-red CTA with the electric blue interactive color in the same element +- Don't use heavy font weights (700+) -- the system maxes out at 600 and only for 11px uppercase labels +- Don't place light text on light surfaces or dark text on dark surfaces without checking the gray-on-gray contrast ratio +- Don't use traditional offset box-shadows -- ring shadows (0 0 0 Npx) or border-based containment only +- Don't break the tight line-height on headings -- 1.00-1.24 is the range, never go to 1.5+ for display text + +## 8.

Visual Theme & Atmosphere + +Sentry's website is a dark-mode-first developer tool interface that speaks the language of code editors and terminal windows. The entire aesthetic is rooted in deep purple-black backgrounds (`#1f1633`, `#150f23`) that evoke the late-night debugging sessions Sentry was built for. Against this inky canvas, a carefully curated set of purples, pinks, and a distinctive lime-green accent (`#c2ef4e`) create a visual system that feels simultaneously technical and vibrant. + +The typography pairing is deliberate: "Dammit Sans" appears at hero scale (88px, weight 700) as a display font with personality and attitude that matches Sentry's irreverent brand voice ("Code breaks. Fix it faster."), while Rubik serves as the workhorse UI font across all functional text — headings, body, buttons, captions, and navigation. Monaco provides the monospace layer for code snippets and technical content, completing the developer-tool trinity. + +What makes Sentry distinctive is its embrace of the "dark IDE" aesthetic without feeling cold or sterile. Warm purple tones replace the typical cool grays of developer tools, and bold illustrative elements (3D characters, colorful product screenshots) punctuate the dark canvas. The button system uses a signature muted purple (`#79628c`) with inset shadows that creates a tactile, almost physical quality — buttons feel like they could be pressed into the surface. + +**Key Characteristics:** +- Dark purple-black backgrounds (`#1f1633`, `#150f23`) — never pure black +- Warm purple accent spectrum: from deep (`#362d59`) through mid (`#79628c`, `#6a5fc1`) to vibrant (`#422082`) +- Lime-green accent (`#c2ef4e`) for high-visibility CTAs and highlights +- Pink/coral accents (`#ffb287`, `#fa7faa`) for focus states and secondary highlights +- "Dammit Sans" display font for brand personality at hero scale +- Rubik as primary UI font with uppercase letter-spaced labels +- Monaco monospace for code elements +- Inset shadows on buttons creating tactile depth +- Frosted glass effects with `blur(18px) saturate(180%)` + +## 2.

Visual Theme & Atmosphere + +SpaceX's website is a full-screen cinematic experience that treats aerospace engineering like a film — every section is a scene, every photograph is a frame, and the interface disappears entirely behind the imagery. The design is pure black (`#000000`) with photography of rockets, space, and planets occupying 100% of the viewport. Text overlays sit directly on these photographs with no background panels, cards, or containers — just type on image, bold and unapologetic. + +The typography system uses D-DIN, an industrial geometric typeface with DIN heritage (the German industrial standard). The defining characteristic is that virtually ALL text is uppercase with positive letter-spacing (0.96px–1.17px), creating a military/aerospace labeling system where every word feels stenciled onto a spacecraft hull. D-DIN-Bold at 48px with uppercase and 0.96px tracking for the hero creates headlines that feel like mission briefing titles. Even body text at 16px maintains the uppercase/tracked treatment at smaller scales. + +What makes SpaceX distinctive is its radical minimalism: no shadows, no borders (except one ghost button border at `rgba(240,240,250,0.35)`), no color (only black and a spectral near-white `#f0f0fa`), no cards, no grids. The only visual element is photography + text. The ghost button with `rgba(240,240,250,0.1)` background and 32px radius is the sole interactive element — barely visible, floating over the imagery like a heads-up display. This isn't a design system in the traditional sense — it's a photographic exhibition with a type system and a single button. + +**Key Characteristics:** +- Pure black canvas with full-viewport cinematic photography — the interface is invisible +- D-DIN / D-DIN-Bold — industrial DIN-heritage typeface +- Universal uppercase + positive letter-spacing (0.96px–1.17px) — aerospace stencil aesthetic +- Near-white spectral text (`#f0f0fa`) — not pure white, a slight blue-violet tint +- Zero shadows, zero cards, zero containers — text on image only +- Single ghost button: `rgba(240,240,250,0.1)` background with spectral border +- Full-viewport sections — each section is a cinematic "scene" +- No decorative elements — every pixel serves the photography + +## 2.

The design philosophy is "content-first darkness" — the UI recedes into shadow so that music, podcasts, and playlists can glow. Every surface is a shade of charcoal, creating a theater-like environment where the only true color comes from the iconic Spotify Green (`#1ed760`) and the album artwork itself. + +The typography uses SpotifyMixUI and SpotifyMixUITitle — proprietary fonts from the CircularSp family (Circular by Lineto, customized for Spotify) with an extensive fallback stack that includes Arabic, Hebrew, Cyrillic, Greek, Devanagari, and CJK fonts, reflecting Spotify's global reach. The type system is compact and functional: 700 (bold) for emphasis and navigation, 600 (semibold) for secondary emphasis, and 400 (regular) for body. Buttons use uppercase with positive letter-spacing (1.4px–2px) for a systematic, label-like quality. + +What distinguishes Spotify is its pill-and-circle geometry. Primary buttons use 500px–9999px radius (full pill), circular play buttons use 50% radius, and search inputs are 500px pills. Combined with heavy shadows (`rgba(0,0,0,0.5) 0px 8px 24px`) on elevated elements and a unique inset border-shadow combo (`rgb(18,18,18) 0px 1px 0px, rgb(124,124,124) 0px 0px 0px 1px inset`), the result is an interface that feels like a premium audio device — tactile, rounded, and built for touch. + +**Key Characteristics:** +- Near-black immersive dark theme (`#121212`–`#1f1f1f`) — UI disappears behind content +- Spotify Green (`#1ed760`) as singular brand accent — never decorative, always functional +- SpotifyMixUI/CircularSp font family with global script support +- Pill buttons (500px–9999px) and circular controls (50%) — rounded, touch-optimized +- Uppercase button labels with wide letter-spacing (1.4px–2px) +- Heavy shadows on elevated elements (`rgba(0,0,0,0.5) 0px 8px 24px`) +- Semantic colors: negative red (`#f3727f`), warning orange (`#ffa42b`), announcement blue (`#539df5`) +- Album art as the primary color source — the UI is achromatic by design + +## 2.

Visual Theme & Atmosphere + +Stripe's website is the gold standard of fintech design -- a system that manages to feel simultaneously technical and luxurious, precise and warm. The page opens on a clean white canvas (`#ffffff`) with deep navy headings (`#061b31`) and a signature purple (`#533afd`) that functions as both brand anchor and interactive accent. This isn't the cold, clinical purple of enterprise software; it's a rich, saturated violet that reads as confident and premium. The overall impression is of a financial institution redesigned by a world-class type foundry. + +The custom `sohne-var` variable font is the defining element of Stripe's visual identity. Every text element enables the OpenType `"ss01"` stylistic set, which modifies character shapes for a distinctly geometric, modern feel. At display sizes (48px-56px), sohne-var runs at weight 300 -- an extraordinarily light weight for headlines that creates an ethereal, almost whispered authority. This is the opposite of the "bold hero headline" convention; Stripe's headlines feel like they don't need to shout. The negative letter-spacing (-1.4px at 56px, -0.96px at 48px) tightens the text into dense, engineered blocks. At smaller sizes, the system also uses weight 300 with proportionally reduced tracking, and tabular numerals via `"tnum"` for financial data display. + +What truly distinguishes Stripe is its shadow system. Rather than the flat or single-layer approach of most sites, Stripe uses multi-layer, blue-tinted shadows: the signature `rgba(50,50,93,0.25)` combined with `rgba(0,0,0,0.1)` creates shadows with a cool, almost atmospheric depth -- like elements are floating in a twilight sky. The blue-gray undertone of the primary shadow color (50,50,93) ties directly to the navy-purple brand palette, making even elevation feel on-brand. + +**Key Characteristics:** +- sohne-var with OpenType `"ss01"` on all text -- a custom stylistic set that defines the brand's letterforms +- Weight 300 as the signature headline weight -- light, confident, anti-convention +- Negative letter-spacing at display sizes (-1.4px at 56px, progressive relaxation downward) +- Blue-tinted multi-layer shadows using `rgba(50,50,93,0.25)` -- elevation that feels brand-colored +- Deep navy (`#061b31`) headings instead of black -- warm, premium, financial-grade +- Conservative border-radius (4px-8px) -- nothing pill-shaped, nothing harsh +- Ruby (`#ea2261`) and magenta (`#f96bee`) accents for gradient and decorative elements +- `SourceCodePro` as the monospace companion for code and technical labels + +## 2.

Where others use 600-700 to command attention, Stripe uses lightness as luxury -- the text is so confident it doesn't need weight to be authoritative. +- **ss01 everywhere**: The `"ss01"` stylistic set is non-negotiable. It modifies specific glyphs (likely alternate `a`, `g`, `l` forms) to create a more geometric, contemporary feel across all sohne-var text. +- **Two OpenType modes**: `"ss01"` for display/body text, `"tnum"` for tabular numerals in financial data. These never overlap -- a number in a paragraph uses ss01, a number in a data table uses tnum. +- **Progressive tracking**: Letter-spacing tightens proportionally with size: -1.4px at 56px, -0.96px at 48px, -0.64px at 32px, -0.26px at 26px, normal at 16px and below. +- **Two-weight simplicity**: Primarily 300 (body and headings) and 400 (UI/buttons). No bold (700) in the primary font -- SourceCodePro uses 500/700 for code contrast. + +## 4.

Every gap is a deliberate typographic choice. +- **Dense data, generous chrome**: Financial data displays (tables, charts) are tightly packed, but the UI chrome around them is generously spaced. This creates a sense of controlled density -- like a well-organized spreadsheet in a beautiful frame. +- **Section rhythm**: White sections alternate with dark brand sections (`#1c1e54`), creating a dramatic light/dark cadence that prevents monotony without introducing arbitrary color. + +### Border Radius Scale +- Micro (1px): Fine-grained elements, subtle rounding +- Standard (4px): Buttons, inputs, badges, cards -- the workhorse +- Comfortable (5px): Standard card containers +- Relaxed (6px): Navigation, larger interactive elements +- Large (8px): Featured cards, hero elements +- Compound: `0px 0px 6px 6px` for bottom-rounded containers (tab panels, dropdown footers) + +## 6.

Where most design systems use neutral gray or black shadows, Stripe's primary shadow color (`rgba(50,50,93,0.25)`) is a deep blue-gray that echoes the brand's navy palette. This creates shadows that don't just add depth -- they add brand atmosphere. The multi-layer approach pairs this blue-tinted shadow with a pure black secondary layer (`rgba(0,0,0,0.1)`) at a different offset, creating a parallax-like depth where the branded shadow sits farther from the element and the neutral shadow sits closer. The negative spread values (-30px, -18px) ensure shadows don't extend beyond the element's footprint horizontally, keeping elevation vertical and controlled. + +### Decorative Depth +- Dark brand sections (`#1c1e54`) create immersive depth through background color contrast +- Gradient overlays with ruby-to-magenta transitions for hero decorations +- Shadow color `rgba(0,55,112,0.08)` (`--hds-color-shadow-sm-top`) for top-edge shadows on sticky elements + +## 7.

Visual Theme & Atmosphere + +Supabase's website is a dark-mode-native developer platform that channels the aesthetic of a premium code editor — deep black backgrounds (`#0f0f0f`, `#171717`) with emerald green accents (`#3ecf8e`, `#00c573`) that reference the brand's open-source, PostgreSQL-green identity. The design system feels like it was born in a terminal window and evolved into a sophisticated marketing surface without losing its developer soul. + +The typography is built on "Circular" — a geometric sans-serif with rounded terminals that softens the technical edge. At 72px with a 1.00 line-height, the hero text is compressed to its absolute minimum vertical space, creating dense, impactful statements that waste nothing. The monospace companion (Source Code Pro) appears sparingly for uppercase technical labels with 1.2px letter-spacing, creating the "developer console" markers that connect the marketing site to the product experience. + +What makes Supabase distinctive is its sophisticated HSL-based color token system. Rather than flat hex values, Supabase uses HSL with alpha channels for nearly every color (`--colors-crimson4`, `--colors-purple5`, `--colors-slateA12`), enabling a nuanced layering system where colors interact through transparency. This creates depth through translucency — borders at `rgba(46, 46, 46)`, surfaces at `rgba(41, 41, 41, 0.84)`, and accents at partial opacity all blend with the dark background to create a rich, dimensional palette from minimal color ingredients. + +The green accent (`#3ecf8e`) appears selectively — in the Supabase logo, in link colors (`#00c573`), and in border highlights (`rgba(62, 207, 142, 0.3)`) — always as a signal of "this is Supabase" rather than as a decorative element. Pill-shaped buttons (9999px radius) for primary CTAs contrast with standard 6px radius for secondary elements, creating a clear visual hierarchy of importance. + +**Key Characteristics:** +- Dark-mode-native: near-black backgrounds (`#0f0f0f`, `#171717`) — never pure black +- Emerald green brand accent (`#3ecf8e`, `#00c573`) used sparingly as identity marker +- Circular font — geometric sans-serif with rounded terminals +- Source Code Pro for uppercase technical labels (1.2px letter-spacing) +- HSL-based color token system with alpha channels for translucent layering +- Pill buttons (9999px) for primary CTAs, 6px radius for secondary +- Neutral gray scale from `#171717` through `#898989` to `#fafafa` +- Border system using dark grays (`#2e2e2e`, `#363636`, `#393939`) +- Minimal shadows — depth through border contrast and transparency +- Radix color primitives (crimson, purple, violet, indigo, yellow, tomato, orange, slate) + +## 2.

Weight 500 appears only for navigation links and button labels. There is no bold (700) in the detected system — hierarchy is created through size, not weight. +- **1.00 hero line-height**: The hero text is compressed to absolute zero leading. This is the defining typographic gesture — text that feels like a terminal command: dense, efficient, no wasted vertical space. +- **Negative tracking on cards**: Card titles use -0.16px letter-spacing, a subtle tightening that differentiates them from body text without being obvious. +- **Monospace as ritual**: Source Code Pro in uppercase with 1.2px letter-spacing is the "developer console" voice — used sparingly for technical labels that connect to the product experience. +- **Geometric personality**: Circular's rounded terminals create warmth in what could otherwise be a cold, technical interface. The font is the humanizing element. + +## 4.

In a dark-mode-native design, shadows are nearly invisible and serve no purpose. Instead, depth is communicated through a sophisticated border hierarchy — from `#242424` (barely visible) through `#2e2e2e` (standard) to `#393939` (prominent). The green accent border (`rgba(62, 207, 142, 0.3)`) at 30% opacity is the "elevated" state — the brand color itself becomes the depth signal. + +## 7. Do's and Don'ts + +### Do +- Use near-black backgrounds (`#0f0f0f`, `#171717`) — depth comes from the gray border hierarchy +- Apply Supabase green (`#3ecf8e`, `#00c573`) sparingly — it's an identity marker, not a decoration +- Use Circular at weight 400 for nearly everything — 500 only for buttons and nav +- Set hero text to 1.00 line-height — the zero-leading is the typographic signature +- Create depth through border color differences (`#242424` → `#2e2e2e` → `#363636`) +- Use pill shape (9999px) exclusively for primary CTAs and tabs +- Employ HSL-based colors with alpha for translucent layering effects +- Use Source Code Pro uppercase labels for developer-context markers + +### Don't +- Don't add box-shadows — they're invisible on dark backgrounds and break the border-defined depth system +- Don't use bold (700) text weight — the system uses 400 and 500 only +- Don't apply green to backgrounds or large surfaces — it's for borders, links, and small accents +- Don't use warm colors (crimson, orange) as primary design elements — they exist as semantic tokens for states +- Don't increase hero line-height above 1.00 — the density is intentional +- Don't use large border radius (16px+) on buttons — pills (9999px) or standard (6px), nothing in between +- Don't lighten the background above `#171717` for primary surfaces — the darkness is structural +- Don't forget the translucent borders — `rgba` border colors are the layering mechanism + +## 8.

Visual Theme & Atmosphere + +Superhuman's website feels like opening a luxury envelope — predominantly white, immaculately clean, with a single dramatic gesture of color that commands attention. The hero section is a cinematic purple gradient, a deep twilight wash of `#1b1938` that evokes the moment just before dawn, overlaid with confident white typography. Below this dramatic entrance, the rest of the site is almost entirely white canvas with dark charcoal text, creating a stark but refined reading experience. + +The typography is the true signature: Super Sans VF, a custom variable font with unconventional weight stops (460, 540, 600, 700) that sit between traditional font weight categories. Weight 460 — slightly heavier than regular but lighter than medium — is the workhorse, creating text that feels more confident than typical 400-weight but never aggressive. The tight line-heights (0.96 on display text) compress headlines into dense, powerful blocks, while generous 1.50 line-height on body text provides airy readability. This tension between compressed power and breathing room defines the Superhuman typographic voice. + +The design philosophy is maximum confidence through minimum decoration. Warm cream buttons (`#e9e5dd`) instead of bright CTAs, a near-absence of borders and shadows, and lavender purple (`#cbb7fb`) as the sole accent color. It's a productivity tool that markets itself like a luxury brand — every pixel earns its place, nothing is merely decorative. The brand naming convention extends to colors: the primary purple is called "Mysteria," straddling blue and purple with deliberate ambiguity. + +**Key Characteristics:** +- Deep purple gradient hero (`#1b1938`) contrasting against a predominantly white content body +- Super Sans VF variable font with non-standard weight stops (460, 540, 600, 700) — sits between conventional weight categories +- Ultra-tight display line-height (0.96) creating compressed, powerful headlines +- Warm Cream (`#e9e5dd`) buttons instead of bright/saturated CTAs — understated luxury +- Lavender Purple (`#cbb7fb`) as the singular accent color — a soft, approachable purple +- Minimal border-radius scale: only 8px and 16px — no micro-rounding, no pill shapes +- Product screenshots dominate the content — the UI sells itself with minimal surrounding decoration + +## 2.

Visual Theme & Atmosphere + +Together AI's interface is a pastel-gradient dreamscape built for enterprise AI infrastructure — a design that somehow makes GPU clusters and model inference feel light, airy, and optimistic. The hero section blooms with soft pink-blue-lavender gradients and abstract, painterly illustrations that evoke clouds and flight, establishing a visual metaphor for the "AI-Native Cloud" proposition. Against this softness, the typography cuts through with precision: "The Future" display font at 64px with aggressive negative tracking (-1.92px) creates dense, authoritative headline blocks. + +The design straddles two worlds: a bright, white-canvas light side where pastel gradients and stats cards create an approachable platform overview, and a dark navy universe (`#010120` — not gray-black but a deep midnight blue) where research papers and technical content live. This dual-world approach elegantly separates the "business" messaging (light, friendly, stat-driven) from the "research" messaging (dark, serious, academic). + +What makes Together AI distinctive is its type system. "The Future" handles all display and body text with a geometric modernist aesthetic, while "PP Neue Montreal Mono" provides uppercase labels with meticulous letter-spacing — creating a "technical infrastructure company with taste" personality. The brand accents — magenta (`#ef2cc1`) and orange (`#fc4c02`) — appear sparingly in the gradient and illustrations, never polluting the clean UI. + +**Key Characteristics:** +- Soft pastel gradients (pink, blue, lavender) against pure white canvas +- Deep midnight blue (`#010120`) for dark/research sections — not gray-black +- Custom "The Future" font with aggressive negative letter-spacing throughout +- PP Neue Montreal Mono for uppercase technical labels +- Sharp geometry (4px, 8px radius) — not rounded, not pill +- Magenta (#ef2cc1) + orange (#fc4c02) brand accents in illustrations only +- Lavender (#bdbbff) as a soft secondary accent +- Enterprise stats prominently displayed (2x, 60%, 90%) +- Dark-blue-tinted shadows (rgba(1, 1, 32, 0.1)) + +## 2. Color Palette & Roles + +### Primary +- **Brand Magenta** (`#ef2cc1`): The primary brand accent — a vivid pink-magenta used in gradient illustrations and the highest-signal brand moments. Never used as UI chrome. +- **Brand Orange** (`#fc4c02`): The secondary brand accent — a vivid orange for gradient endpoints and warm accent moments. +- **Dark Blue** (`#010120`): The primary dark surface — a deep midnight blue-black used for research sections, footer, and dark containers. Not gray, not black — distinctly blue. + +### Secondary & Accent +- **Soft Lavender** (`#bdbbff`): A gentle blue-violet used for subtle accents, secondary indicators, and soft UI highlights. +- **Black 40** (`#00000066`): Semi-transparent black for de-emphasized overlays and secondary text. + +### Surface & Background +- **Pure White** (`#ffffff`): The primary light-section page background. +- **Dark Blue** (`#010120`): Dark-section backgrounds — research, footer, technical content. +- **Glass Light** (`rgba(255, 255, 255, 0.12)`): Frosted glass button backgrounds on dark sections. +- **Glass Dark** (`rgba(0, 0, 0, 0.08)`): Subtle tinted surfaces on light sections. + +### Neutrals & Text +- **Pure Black** (`#000000`): Primary text on light surfaces. +- **Pure White** (`#ffffff`): Primary text on dark surfaces. +- **Black 8%** (`rgba(0, 0, 0, 0.08)`): Borders and subtle containment on light surfaces. +- **White 12%** (`rgba(255, 255, 255, 0.12)`): Borders and containment on dark surfaces. + +### Gradient System +- **Pastel Cloud Gradient**: Soft pink → lavender → soft blue gradients in hero illustrations. These appear in abstract, painterly forms — clouds, feathers, flowing shapes — that create visual warmth without literal meaning. +- **Hero Gradient**: The hero background uses soft pastel tints layered over white, creating a dawn-like atmospheric effect. + +## 3.

Visual Theme & Atmosphere + +Uber's design language is a masterclass in confident minimalism -- a black-and-white universe where every pixel serves a purpose and nothing decorates without earning its place. The entire experience is built on a stark duality: jet black (`#000000`) and pure white (`#ffffff`), with virtually no mid-tone grays diluting the message. This isn't the sterile minimalism of a startup that hasn't finished designing -- it's the deliberate restraint of a brand so established it can afford to whisper. + +The signature typeface, UberMove, is a proprietary geometric sans-serif with a distinctly square, engineered quality. Headlines in UberMove Bold at 52px carry the weight of a billboard -- authoritative, direct, unapologetic. The companion face UberMoveText handles body copy and buttons with a slightly softer, more readable character at medium weight (500). Together, they create a typographic system that feels like a transit map: clear, efficient, built for scanning at speed. + +What makes Uber's design truly distinctive is its use of full-bleed photography and illustration paired with pill-shaped interactive elements (999px border-radius). Navigation chips, CTA buttons, and category selectors all share this capsule shape, creating a tactile, thumb-friendly interface language that's unmistakably Uber. The illustrations -- warm, slightly stylized scenes of drivers, riders, and cityscapes -- inject humanity into what could otherwise be a cold, monochrome system. The site alternates between white content sections and a full-black footer, with card-based layouts using the gentlest possible shadows (rgba(0,0,0,0.12-0.16)) to create subtle lift without breaking the flat aesthetic. + +**Key Characteristics:** +- Pure black-and-white foundation with virtually no mid-tone grays in the UI chrome +- UberMove (headlines) + UberMoveText (body/UI) -- proprietary geometric sans-serif family +- Pill-shaped everything: buttons, chips, nav items all use 999px border-radius +- Warm, human illustrations contrasting the stark monochrome interface +- Card-based layout with whisper-soft shadows (0.12-0.16 opacity) +- 8px spacing grid with compact, information-dense layouts +- Bold photography integrated as full-bleed hero backgrounds +- Black footer anchoring the page with a dark, high-contrast environment + +## 2. Color Palette & Roles + +### Primary +- **Uber Black** (`#000000`): The defining brand color -- used for primary buttons, headlines, navigation text, and the footer. Not "near-black" or "off-black," but true, uncompromising black. +- **Pure White** (`#ffffff`): The primary surface color and inverse text. Used for page backgrounds, card surfaces, and text on black elements. + +### Interactive & Button States +- **Hover Gray** (`#e2e2e2`): White button hover state -- a clean, cool light gray that provides clear feedback without warmth. +- **Hover Light** (`#f3f3f3`): Subtle hover for elevated white buttons -- barely-there gray for gentle interaction feedback. +- **Chip Gray** (`#efefef`): Background for secondary/filter buttons and navigation chips -- a neutral, ultra-light gray. + +### Text & Content +- **Body Gray** (`#4b4b4b`): Secondary text and footer links -- a true mid-gray with no warm or cool bias. +- **Muted Gray** (`#afafaf`): Tertiary text, de-emphasized footer links, and placeholder content. + +### Borders & Separation +- **Border Black** (`#000000`): Thin 1px borders for structural containment -- used sparingly on dividers and form containers. + +### Shadows & Depth +- **Shadow Light** (`rgba(0, 0, 0, 0.12)`): Standard card elevation -- a featherweight lift for content cards. +- **Shadow Medium** (`rgba(0, 0, 0, 0.16)`): Slightly stronger elevation for floating action buttons and overlays. +- **Button Press** (`rgba(0, 0, 0, 0.08)`): Inset shadow for active/pressed states on secondary buttons. + +### Link States +- **Default Link Blue** (`#0000ee`): Standard browser blue for text links with underline -- used in body content. +- **Link White** (`#ffffff`): Links on dark surfaces -- used in footer and dark sections. +- **Link Black** (`#000000`): Links on light surfaces with underline decoration. + +### Gradient System +- Uber's design is **entirely gradient-free**.

Visual Theme & Atmosphere + +Vercel's website is the visual thesis of developer infrastructure made invisible — a design system so restrained it borders on philosophical. The page is overwhelmingly white (`#ffffff`) with near-black (`#171717`) text, creating a gallery-like emptiness where every element earns its pixel. This isn't minimalism as decoration; it's minimalism as engineering principle. The Geist design system treats the interface like a compiler treats code — every unnecessary token is stripped away until only structure remains. + +The custom Geist font family is the crown jewel. Geist Sans uses aggressive negative letter-spacing (-2.4px to -2.88px at display sizes), creating headlines that feel compressed, urgent, and engineered — like code that's been minified for production. At body sizes, the tracking relaxes but the geometric precision persists. Geist Mono completes the system as the monospace companion for code, terminal output, and technical labels. Both fonts enable OpenType `"liga"` (ligatures) globally, adding a layer of typographic sophistication that rewards close reading. + +What distinguishes Vercel from other monochrome design systems is its shadow-as-border philosophy. Instead of traditional CSS borders, Vercel uses `box-shadow: 0px 0px 0px 1px rgba(0,0,0,0.08)` — a zero-offset, zero-blur, 1px-spread shadow that creates a border-like line without the box model implications. This technique allows borders to exist in the shadow layer, enabling smoother transitions, rounded corners without clipping, and a subtler visual weight than traditional borders. The entire depth system is built on layered, multi-value shadow stacks where each layer serves a specific purpose: one for the border, one for soft elevation, one for ambient depth. + +**Key Characteristics:** +- Geist Sans with extreme negative letter-spacing (-2.4px to -2.88px at display) — text as compressed infrastructure +- Geist Mono for code and technical labels with OpenType `"liga"` globally +- Shadow-as-border technique: `box-shadow 0px 0px 0px 1px` replaces traditional borders throughout +- Multi-layer shadow stacks for nuanced depth (border + elevation + ambient in single declarations) +- Near-pure white canvas with `#171717` text — not quite black, creating micro-contrast softness +- Workflow-specific accent colors: Ship Red (`#ff5b4f`), Preview Pink (`#de1d8d`), Develop Blue (`#0a72ef`) +- Focus ring system using `hsla(212, 100%, 48%, 1)` — a saturated blue for accessibility +- Pill badges (9999px) with tinted backgrounds for status indicators + +## 2.

This creates text that feels _minified_, like code optimized for production. The tracking progressively relaxes as size decreases: -1.28px at 32px, -0.96px at 24px, -0.32px at 16px, and normal at 14px. +- **Ligatures everywhere**: Every Geist text element enables OpenType `"liga"`. Ligatures aren't decorative — they're structural, creating tighter, more efficient glyph combinations. +- **Three weights, strict roles**: 400 (body/reading), 500 (UI/interactive), 600 (headings/emphasis). No bold (700) except for tiny micro-badges. This narrow weight range creates hierarchy through size and tracking, not weight. +- **Mono for identity**: Geist Mono in uppercase with `"tnum"` or `"liga"` serves as the "developer console" voice — compact technical labels that connect the marketing site to the product. + +## 4.

The white space IS the design — it communicates that Vercel has nothing to prove and nothing to hide. +- **Compressed text, expanded space**: The aggressive negative letter-spacing on headlines is counterbalanced by generous surrounding whitespace. The text is dense; the space around it is vast. +- **Section rhythm**: White sections alternate with white sections — there's no color variation between sections. Separation comes from borders (shadow-borders) and spacing alone. + +### Border Radius Scale +- Micro (2px): Inline code snippets, small spans +- Subtle (4px): Small containers +- Standard (6px): Buttons, links, functional elements +- Comfortable (8px): Cards, list items +- Image (12px): Featured cards, image containers (top-rounded) +- Large (64px): Tab navigation pills +- XL (100px): Large navigation links +- Full Pill (9999px): Badges, status pills, tags +- Circle (50%): Menu toggle, avatar containers + +## 6.

Rather than using shadows for elevation in the traditional Material Design sense, Vercel uses multi-value shadow stacks where each layer has a distinct architectural purpose: one creates the "border" (0px spread, 1px), another adds ambient softness (2px blur), another handles depth at distance (8px blur with negative spread), and an inner ring (`#fafafa`) creates the subtle highlight that makes the card "glow" from within. This layered approach means cards feel built, not floating. + +### Decorative Depth +- Hero gradient: soft, pastel multi-color gradient wash behind hero content (barely visible, atmospheric) +- Section borders: `1px solid #171717` (full dark line) between major sections +- No background color variation — depth comes entirely from shadow layering and border contrast + +## 7. Do's and Don'ts + +### Do +- Use Geist Sans with aggressive negative letter-spacing at display sizes (-2.4px to -2.88px at 48px) +- Use shadow-as-border (`0px 0px 0px 1px rgba(0,0,0,0.08)`) instead of traditional CSS borders +- Enable `"liga"` on all Geist text — ligatures are structural, not optional +- Use the three-weight system: 400 (body), 500 (UI), 600 (headings) +- Apply workflow accent colors (Red/Pink/Blue) only in their workflow context +- Use multi-layer shadow stacks for cards (border + elevation + ambient + inner highlight) +- Keep the color palette achromatic — grays from `#171717` to `#ffffff` are the system +- Use `#171717` instead of `#000000` for primary text — the micro-warmth matters + +### Don't +- Don't use positive letter-spacing on Geist Sans — it's always negative or zero +- Don't use weight 700 (bold) on body text — 600 is the maximum, used only for headings +- Don't use traditional CSS `border` on cards — use the shadow-border technique +- Don't introduce warm colors (oranges, yellows, greens) into the UI chrome +- Don't apply the workflow accent colors (Ship Red, Preview Pink, Develop Blue) decoratively +- Don't use heavy shadows (> 0.1 opacity) — the shadow system is whisper-level +- Don't increase body text letter-spacing — Geist is designed to run tight +- Don't use pill radius (9999px) on primary action buttons — pills are for badges/tags only +- Don't skip the inner `#fafafa` ring in card shadows — it's the glow that makes the system work + +## 8.

Visual Theme & Atmosphere + +VoltAgent's interface is a deep-space command terminal for the AI age — a developer-facing darkness built on near-pure-black surfaces (`#050507`) where the only interruption is the electric pulse of emerald green energy. The entire experience evokes the feeling of staring into a high-powered IDE at 2am: dark, focused, and alive with purpose. This is not a friendly SaaS landing page — it's an engineering platform that announces itself through code snippets, architectural diagrams, and raw technical confidence. + +The green accent (`#00d992`) is used with surgical precision — it glows from headlines, borders, and interactive elements like a circuit board carrying a signal. Against the carbon-black canvas, this green reads as "power on" — a deliberate visual metaphor for an AI agent engineering platform. The supporting palette is built entirely from warm-neutral grays (`#3d3a39`, `#8b949e`, `#b8b3b0`) that soften the darkness without introducing color noise, creating a cockpit-like warmth that pure blue-grays would lack. + +Typography leans on the system font stack for headings — achieving maximum rendering speed and native-feeling authority — while Inter carries the body and UI text with geometric precision. Code blocks use SFMono-Regular, the same font developers see in their terminals, reinforcing the tool's credibility at every scroll. + +**Key Characteristics:** +- Carbon-black canvas (`#050507`) with warm-gray border containment (`#3d3a39`) — not cold or sterile +- Single-accent identity: Emerald Signal Green (`#00d992`) as the sole chromatic energy source +- Dual-typography system: system-ui for authoritative headings, Inter for precise UI/body text, SFMono for code credibility +- Ultra-tight heading line-heights (1.0–1.11) creating dense, compressed power blocks +- Warm neutral palette (`#3d3a39`, `#8b949e`, `#b8b3b0`) that prevents the dark theme from feeling clinical +- Developer-terminal aesthetic where code snippets ARE the hero content +- Green glow effects (`drop-shadow`, border accents) that make UI elements feel electrically alive + +## 2. Color Palette & Roles + +### Primary +- **Emerald Signal Green** (`#00d992`): The core brand energy — used for accent borders, glow effects, and the highest-signal interactive moments. This is the "power-on" indicator of the entire interface. +- **VoltAgent Mint** (`#2fd6a1`): The button-text variant of the brand green — slightly warmer and more readable than pure Signal Green, used specifically for CTA text on dark surfaces. +- **Tailwind Emerald** (`#10b981`): The ecosystem-standard green used at low opacity (30%) for subtle background tints and link defaults. Bridges VoltAgent's custom palette with Tailwind's utility classes. + +### Secondary & Accent +- **Soft Purple** (`#818cf8`): A cool indigo-violet used sparingly for secondary categorization, code syntax highlights, and visual variety without competing with green. +- **Cobalt Primary** (`#306cce`): Docusaurus primary dark — used in documentation contexts for links and interactive focus states. +- **Deep Cobalt** (`#2554a0`): The darkest primary shade, reserved for pressed/active states in documentation UI. +- **Ring Blue** (`#3b82f6`): Tailwind's ring color at 50% opacity — visible only during keyboard focus for accessibility compliance. + +### Surface & Background +- **Abyss Black** (`#050507`): The landing page canvas — a near-pure black with the faintest warm undertone, darker than most "dark themes" for maximum contrast with green accents. +- **Carbon Surface** (`#101010`): The primary card and button background — one shade lighter than Abyss, creating a barely perceptible elevation layer. Used across all contained surfaces. +- **Warm Charcoal Border** (`#3d3a39`): The signature containment color — not a cold gray but a warm, almost brownish dark tone that prevents borders from feeling harsh against the black canvas. + +### Neutrals & Text +- **Snow White** (`#f2f2f2`): The primary text color on dark surfaces — not pure white (`#ffffff`) but a softened, eye-friendly off-white. The most-used color on the site (1008 instances). +- **Pure White** (`#ffffff`): Reserved for the highest-emphasis moments — ghost button text and maximum-contrast headings. Used at low opacity (5%) for subtle overlay effects. +- **Warm Parchment** (`#b8b3b0`): Secondary body text — a warm light gray with a slight pinkish undertone that reads as "paper" against the dark canvas. +- **Steel Slate** (`#8b949e`): Tertiary text, metadata, timestamps, and de-emphasized content. A cool blue-gray that provides clear hierarchy below Warm Parchment. +- **Fog Gray** (`#bdbdbd`): Footer links and supporting navigation text — brightens on hover to Pure White. +- **Mist Gray** (`#dcdcdc`): Slightly brighter than Fog, used for secondary link text that transitions to bright green on hover. +- **Near White** (`#eeeeee`): Highest-contrast secondary text, one step below Snow White. + +### Semantic & Accent +- **Success Emerald** (`#008b00`): Deep green for success states and positive confirmations in documentation contexts. +- **Success Light** (`#80d280`): Soft pastel green for success backgrounds and subtle positive indicators. +- **Warning Amber** (`#ffba00`): Bright amber for warning alerts and caution states. +- **Warning Pale** (`#ffdd80`): Softened amber for warning background fills. +- **Danger Coral** (`#fb565b`): Vivid red for error states and destructive action warnings. +- **Danger Rose** (`#fd9c9f`): Softened coral-pink for error backgrounds. +- **Info Teal** (`#4cb3d4`): Cool teal-blue for informational callouts and tip admonitions. +- **Dashed Border Slate** (`#4f5d75` at 40%): A muted blue-gray used exclusively for decorative dashed borders in workflow diagrams. + +### Gradient System +- **Green Signal Glow**: `drop-shadow(0 0 2px #00d992)` animating to `drop-shadow(0 0 8px #00d992)` — creates a pulsing "electric charge" effect on the VoltAgent bolt logo and interactive elements.

On macOS it's SF Pro, on Windows it's Segoe UI. The design accepts this variability as a feature, not a bug. +- **Tight compression creates density**: Hero line-heights are extremely compressed (1.0) with negative letter-spacing (-0.65px to -0.9px), creating text blocks that feel like dense technical specifications rather than airy marketing copy. +- **Weight gradient, not weight contrast**: The system uses a gentle 300→400→500→600→700 weight progression. Bold (700) is reserved for sub-headings and code-button emphasis. Most body text lives at 400–500, creating subtle rather than dramatic hierarchy. +- **Uppercase is earned and wide**: When uppercase appears, it's always paired with generous letter-spacing (0.45px–2.52px), transforming dense words into spaced-out overline labels. This treatment is never applied to headings. +- **OpenType by default**: Both system-ui and Inter enable `"calt"` and `"rlig"` features, ensuring contextual character adjustments and ligature rendering throughout. + +## 4.

Information is concentrated, not spread thin. +- **Border-defined separation**: Rather than relying solely on whitespace, VoltAgent uses the Warm Charcoal border system (`#3d3a39`) to delineate content zones. The border IS the whitespace signal. +- **Hero-first hierarchy**: The top of the page commands the most space — the "AI Agent Engineering Platform" headline and npm command get maximum vertical runway before the first content section appears. + +### Border Radius Scale +- Nearly squared (4px): Small inline elements, SVG containers, code spans — the sharpest treatment, conveying technical precision +- Subtly rounded (6px): Buttons, links, clipboard actions — the workhorse radius for interactive elements +- Code-specific (6.4px): Code blocks, `pre` elements, clipboard copy targets — a deliberate micro-distinction from standard 6px +- Comfortably rounded (8px): Content cards, feature containers, emphasized buttons — the standard containment radius +- Pill-shaped (9999px): Tags, badges, status indicators, pill-shaped navigation elements — the roundest treatment for small categorical labels + +## 6.

The standard `1px solid #3d3a39` border IS the elevation — adding a `3px` border weight or switching to green (`#00d992`) communicates importance more than adding shadow does. When shadows do appear, they're either warm and diffused (Level 4) or cinematic and dramatic (Level 5) — never medium or generic. + +### Decorative Depth +- **Green Signal Glow**: The VoltAgent bolt logo pulses with a `drop-shadow` animation cycling between 2px and 8px blur radius in Emerald Signal Green. This is the most distinctive decorative element — it makes the logo feel "powered on." +- **Warm Charcoal Containment Lines**: The warm tone of `#3d3a39` borders creates a subtle visual warmth against the cool black, as if the cards are faintly heated from within. +- **Dashed Workflow Lines**: `1px dashed rgba(79, 93, 117, 0.4)` creates a blueprint-like aesthetic for architecture diagrams, visually distinct from solid content borders. + +## 7. Do's and Don'ts + +### Do +- Use Abyss Black (`#050507`) as the landing page background and Carbon Surface (`#101010`) for all contained elements — the two-shade dark system is essential +- Reserve Emerald Signal Green (`#00d992`) exclusively for high-signal moments: active borders, glow effects, and the most important interactive accents +- Use VoltAgent Mint (`#2fd6a1`) for button text on dark surfaces — it's more readable than pure Signal Green +- Keep heading line-heights compressed (1.0–1.11) with negative letter-spacing for dense, authoritative text blocks +- Use the warm gray palette (`#3d3a39`, `#8b949e`, `#b8b3b0`) for borders and secondary text — warmth prevents the dark theme from feeling sterile +- Present code snippets as primary content — they're hero elements, not supporting illustrations +- Use border weight (1px → 2px → 3px) and color shifts (`#3d3a39` → `#00d992`) to communicate depth and importance, rather than relying on shadows +- Pair system-ui for headings with Inter for body text — the speed/authority of native fonts combined with the precision of a geometric sans +- Use SFMono-Regular for all code content — it's the developer credibility signal +- Apply `"calt"` and `"rlig"` OpenType features across all text + +### Don't +- Don't use bright or light backgrounds as primary surfaces — the entire identity lives on near-black +- Don't introduce warm colors (orange, red, yellow) as decorative accents — the palette is strictly green + warm neutrals on black. Warm colors are reserved for semantic states (warning, error) only +- Don't use Emerald Signal Green (`#00d992`) on large surfaces or as background fills — it's an accent, never a surface +- Don't increase heading line-heights beyond 1.33 — the compressed density is core to the engineering-platform identity +- Don't use heavy shadows generously — depth comes from border treatment, not box-shadow. Shadows are reserved for Level 4–5 elevation only +- Don't use pure white (`#ffffff`) as default body text — Snow White (`#f2f2f2`) is the standard. Pure white is reserved for maximum-emphasis headings and button text +- Don't mix in serif or decorative fonts — the entire system is geometric sans + monospace +- Don't use border-radius larger than 8px on content cards — 9999px (pill) is only for small tags and badges +- Don't skip the warm-gray border system — cards without `#3d3a39` borders lose their containment and float ambiguously on the dark canvas +- Don't animate aggressively — animations are slow and subtle (25–100s durations for marquee, gentle glow pulses).

Visual Theme & Atmosphere + +Warp's website feels like sitting at a campfire in a deep forest — warm, dark, and alive with quiet confidence. Unlike the cold, blue-tinted blacks favored by most developer tools, Warp wraps everything in a warm near-black that feels like charred wood or dark earth. The text isn't pure white either — it's Warm Parchment (`#faf9f6`), a barely-perceptible cream that softens every headline and makes the dark canvas feel inviting rather than austere. + +The typography is the secret weapon: Matter, a geometric sans-serif with distinctive character, deployed at Regular weight across virtually all text. The font choice is unusual for a developer tool — Matter has a softness and humanity that signals "this terminal is for everyone, not just greybeards." Combined with tight line-heights and controlled negative letter-spacing on headlines, the effect is refined and approachable simultaneously. Nature photography is woven between terminal screenshots, creating a visual language that says: this tool brings you closer to flow, to calm productivity. + +The overall design philosophy is restraint through warmth.

The design operates on a warm off-white canvas with near-black text (`#0e0f0c`) and a signature Wise Green (`#9fe870`) — a fresh, lime-bright color that feels alive and optimistic, unlike the corporate blues of traditional banking. + +The typography uses Wise Sans — a proprietary font used at extreme weight 900 (black) for display headings with a remarkably tight line-height of 0.85 and OpenType `"calt"` (contextual alternates).

Visual Theme & Atmosphere + +xAI's website is a masterclass in dark-first, monospace-driven brutalist minimalism -- a design system that feels like it was built by engineers who understand that restraint is the ultimate form of sophistication. The entire experience is anchored to an almost-black background (`#1f2228`) with pure white text (`#ffffff`), creating a high-contrast, terminal-inspired aesthetic that signals deep technical credibility. There are no gradients, no decorative illustrations, no color accents competing for attention. This is a site that communicates through absence. + +The typographic system is split between two carefully chosen typefaces. `GeistMono` (Vercel's monospace font) handles display-level headlines at an extraordinary 320px with weight 300, and also serves as the button typeface in uppercase with tracked-out letter-spacing (1.4px). `universalSans` handles all body and secondary heading text with a clean, geometric sans-serif voice. The monospace-as-display-font choice is the defining aesthetic decision -- it positions xAI not as a consumer product but as infrastructure, as something built by people who live in terminals. + +The spacing system operates on an 8px base grid with values concentrated at the small end (4px, 8px, 24px, 48px), reflecting a dense, information-focused layout philosophy. Border radius is minimal -- the site barely rounds anything, maintaining sharp, architectural edges. There are no decorative shadows, no gradients, no layered elevation. Depth is communicated purely through contrast and whitespace. + +**Key Characteristics:** +- Pure dark theme: `#1f2228` background with `#ffffff` text -- no gray middle ground +- GeistMono at extreme display sizes (320px, weight 300) -- monospace as luxury +- Uppercase monospace buttons with 1.4px letter-spacing -- technical, commanding +- universalSans for body text at 16px/1.5 and headings at 30px/1.2 -- clean contrast +- Zero decorative elements: no shadows, no gradients, no colored accents +- 8px spacing grid with a sparse, deliberate scale +- Heroicons SVG icon system -- minimal, functional +- Tailwind CSS with arbitrary values -- utility-first engineering approach + +## 2. Color Palette & Roles + +### Primary +- **Pure White** (`#ffffff`): The singular text color, link color, and all foreground elements. In xAI's system, white is not a background -- it is the voice. +- **Dark Background** (`#1f2228`): The canvas. A warm near-black with a subtle blue undertone (not pure black, not neutral gray). This specific hue prevents the harsh eye strain of `#000000` while maintaining deep darkness. + +### Interactive +- **White Default** (`#ffffff`): Link and interactive element color in default state. +- **White Muted** (`rgba(255, 255, 255, 0.5)`): Hover state for links -- a deliberate dimming rather than brightening, which is unusual and distinctive. +- **White Subtle** (`rgba(255, 255, 255, 0.2)`): Borders, dividers, and subtle surface treatments. +- **Ring Blue** (`rgb(59, 130, 246) / 0.5`): Tailwind's default focus ring color (`--tw-ring-color`), used for keyboard accessibility focus states. + +### Surface & Borders +- **Surface Elevated** (`rgba(255, 255, 255, 0.05)`): Subtle card backgrounds and hover surfaces -- barely visible lift. +- **Surface Hover** (`rgba(255, 255, 255, 0.08)`): Slightly more visible hover state for interactive containers. +- **Border Default** (`rgba(255, 255, 255, 0.1)`): Standard border for cards, dividers, and containers. +- **Border Strong** (`rgba(255, 255, 255, 0.2)`): Emphasized borders for active states and button outlines. + +### Functional +- **Text Primary** (`#ffffff`): All headings, body text, labels. +- **Text Secondary** (`rgba(255, 255, 255, 0.7)`): Descriptions, captions, supporting text. +- **Text Tertiary** (`rgba(255, 255, 255, 0.5)`): Muted labels, placeholder text, timestamps. +- **Text Quaternary** (`rgba(255, 255, 255, 0.3)`): Disabled text, very subtle annotations. + +## 3. Typography Rules + +### Font Family +- **Display / Buttons**: `GeistMono`, with fallback: `ui-monospace, SFMono-Regular, Roboto Mono, Menlo, Monaco, Liberation Mono, DejaVu Sans Mono, Courier New` +- **Body / Headings**: `universalSans`, with fallback: `universalSans Fallback` + +### Hierarchy + +| Role | Font | Size | Weight | Line Height | Letter Spacing | Transform | Notes | +|------|------|------|--------|-------------|----------------|-----------|-------| +| Display Hero | GeistMono | 320px (20rem) | 300 | 1.50 | normal | none | Extreme scale, monospace luxury | +| Section Heading | universalSans | 30px (1.88rem) | 400 | 1.20 (tight) | normal | none | Clean sans-serif contrast | +| Body | universalSans | 16px (1rem) | 400 | 1.50 | normal | none | Standard reading text | +| Button | GeistMono | 14px (0.88rem) | 400 | 1.43 | 1.4px | uppercase | Tracked monospace, commanding | +| Label / Caption | universalSans | 14px (0.88rem) | 400 | 1.50 | normal | none | Supporting text | +| Small / Meta | universalSans | 12px (0.75rem) | 400 | 1.50 | normal | none | Timestamps, footnotes | + +### Principles +- **Monospace as display**: GeistMono at 320px is not a gimmick -- it is the brand statement. The fixed-width characters at extreme scale create a rhythmic, architectural quality that no proportional font can achieve. +- **Light weight at scale**: Weight 300 for the 320px headline prevents the monospace from feeling heavy or brutish at extreme sizes. It reads as precise, not overwhelming. +- **Uppercase buttons**: All button text is uppercase GeistMono with 1.4px letter-spacing. This creates a distinctly technical, almost command-line aesthetic for interactive elements. +- **Sans-serif for reading**: universalSans at 16px/1.5 provides excellent readability for body content, creating a clean contrast against the monospace display elements. +- **Two-font clarity**: The system uses exactly two typefaces with clear roles -- monospace for impact and interaction, sans-serif for information and reading. No overlap, no ambiguity. + +## 4.

Layout Principles + +### Spacing System +- Base unit: 8px +- Scale: 4px, 8px, 24px, 48px +- The scale is deliberately sparse -- xAI avoids granular spacing distinctions, preferring large jumps that create clear visual hierarchy through whitespace alone + +### Grid & Container +- Max content width: approximately 1200px +- Hero: full-viewport height with massive centered monospace headline +- Feature sections: simple vertical stacking with generous section padding (48px-96px) +- Two-column layouts for feature descriptions at desktop +- Full-width dark sections maintain the single dark background throughout + +### Whitespace Philosophy +- **Extreme generosity**: xAI uses vast amounts of whitespace. The 320px headline with 48px+ surrounding padding creates a sense of emptiness that is itself a design statement -- the content is so important it needs room to breathe. +- **Vertical rhythm over horizontal density**: Content stacks vertically with large gaps between sections rather than packing horizontally. This creates a scroll-driven experience that feels deliberate and cinematic. +- **No visual noise**: The absence of decorative elements, borders between sections, and color variety means whitespace is the primary structural tool. + +### Breakpoints +- 2000px, 1536px, 1280px, 1024px, 1000px, 768px, 640px +- Tailwind responsive modifiers drive breakpoint behavior + +### Border Radius Scale +- Sharp (0px): Primary treatment for buttons, cards, inputs -- the default +- Subtle (4px): Occasional softening on secondary containers +- The near-zero radius philosophy is core to the brand's brutalist identity + +## 6. Depth & Elevation + +| Level | Treatment | Use | +|-------|-----------|-----| +| Flat (Level 0) | No shadow, no border | Page background, body content | +| Surface (Level 1) | `rgba(255,255,255,0.03)` background | Subtle card surfaces | +| Bordered (Level 2) | `1px solid rgba(255,255,255,0.1)` border | Cards, containers, dividers | +| Active (Level 3) | `1px solid rgba(255,255,255,0.2)` border | Hover states, active elements | +| Focus (Accessibility) | `ring` with `rgb(59,130,246)/0.5` | Keyboard focus indicator | + +**Elevation Philosophy**: xAI rejects the conventional shadow-based elevation system entirely. There are no box-shadows anywhere on the site. Instead, depth is communicated through three mechanisms: (1) opacity-based borders that brighten on interaction, creating a sense of elements "activating" rather than lifting; (2) extremely subtle background opacity shifts (`0.03` to `0.08`) that create barely-perceptible surface differentiation; and (3) the massive scale contrast between the 320px display type and 16px body text, which creates typographic depth. This is elevation through contrast and opacity, not through simulated light and shadow. + +## 7.

Visual Theme & Atmosphere + +Zapier's website radiates warm, approachable professionalism. It rejects the cold monochrome minimalism of developer tools in favor of a cream-tinted canvas (`#fffefb`) that feels like unbleached paper -- the digital equivalent of a well-organized notebook. The near-black (`#201515`) text has a faint reddish-brown warmth, creating an atmosphere more human than mechanical. This is automation designed to feel effortless, not technical. + +The typographic system is a deliberate interplay of two distinct personalities. **Degular Display** -- a geometric, wide-set display face -- handles hero-scale headlines at 56-80px with medium weight (500) and extraordinarily tight line-heights (0.90), creating headlines that compress vertically like stacked blocks. **Inter** serves as the workhorse for everything else, from section headings to body text and navigation, with fallbacks to Helvetica and Arial. **GT Alpina**, an elegant thin-weight serif with aggressive negative letter-spacing (-1.6px to -1.92px), makes occasional appearances for softer editorial moments. This three-font system gives Zapier the ability to shift register -- from bold and punchy (Degular) to clean and functional (Inter) to refined and literary (GT Alpina). + +The brand's signature orange (`#ff4f00`) is unmistakable -- a vivid, saturated red-orange that sits precisely between traffic-cone urgency and sunset warmth. It's used sparingly but decisively: primary CTA buttons, active state underlines, and accent borders. Against the warm cream background, this orange creates a color relationship that feels energetic without being aggressive. + +**Key Characteristics:** +- Warm cream canvas (`#fffefb`) instead of pure white -- organic, paper-like warmth +- Near-black with reddish undertone (`#201515`) -- text that breathes rather than dominates +- Degular Display for hero headlines at 0.90 line-height -- compressed, impactful, modern +- Inter as the universal UI font across all functional typography +- GT Alpina for editorial accents -- thin-weight serif with extreme negative tracking +- Zapier Orange (`#ff4f00`) as the single accent -- vivid, warm, sparingly applied +- Warm neutral palette: borders (`#c5c0b1`), muted text (`#939084`), surface tints (`#eceae3`) +- 8px base spacing system with generous padding on CTAs (20px 24px) +- Border-forward design: `1px solid` borders in warm grays define structure over shadows + +## 2. Color Palette & Roles + +### Primary +- **Zapier Black** (`#201515`): Primary text, headings, dark button backgrounds.

Not pure white; the yellowish warmth is intentional. +- **Off-White** (`#fffdf9`): Secondary background surface, subtle alternate tint. Nearly indistinguishable from cream white but creates depth. + +### Brand Accent +- **Zapier Orange** (`#ff4f00`): Primary CTA buttons, active underline indicators, accent borders.

Inspect the actual deliverable and run relevant verification. +3. Choose exactly one verdict: approve, request changes, or escalate. +4. Record concrete evidence in the terminal Kanban transition. + +## Quick Reference + +| Verdict | When | Final action | +|---|---|---| +| Approve | Acceptance criteria and verification pass | `kanban_complete` | +| Request changes | Correctable implementation defects remain | `kanban_comment`, then `kanban_request_changes` | +| Escalate | A human decision or external prerequisite is required | `kanban_block` | + +A requested-changes transition returns the task to its original implementer. When that implementer requests review again without naming a reviewer, the persisted reviewer provenance routes the re-review back to the same reviewer profile. + +## Review Lenses + +Vary how you look at the work on each round instead of repeating the same inspection. Decorrelated lenses catch different defect classes: a cold read of the artifact surfaces design and correctness problems that the implementer's narrative would have framed away, execution surfaces claims that do not reproduce, and a strict contract audit surfaces quiet scope drift. Repeating the round-1 lens on round 3 mostly re-finds what round 1 already found. + +Determine the current round from the history the task record already gives you: count the `changes_requested` entries in the "Prior attempts on this task" section of your worker context (also visible as prior runs in `kanban_show`). The current review round is that count plus one. Round 1 therefore shows zero `changes_requested` attempts; round 2 shows one; and so on. + +| Round | Lens | How to apply it | +|---|---|---| +| 1 | Artifact | Read the diff or deliverable cold, before the implementer's summary. Form an independent judgment, then compare it against the handoff narrative and investigate every mismatch. | +| 2 | Execution | Check out the work and actually run it via `terminal`: build, test, and exercise the reported behavior yourself. Verify each handoff claim empirically instead of re-reading the artifact. | +| 3+ | Contract | Re-read the ORIGINAL task body and acceptance criteria, then audit the deliverable strictly against them. Also verify that every item from every prior `kanban_request_changes` round actually landed. | + +The baseline duties in the Procedure section still apply on every round; the lens sets which inspection you lead with and weight most heavily. + +### Lens variation for ad-hoc review fan-outs + +The same principle applies outside the Kanban review lane. When spawning multiple parallel reviewers via `delegate_task`, give each reviewer a different lens — one diff-only brief, one full-context brief, one checkout-and-run brief — rather than identical briefs. Identical briefs produce correlated verdicts and duplicate findings; varied briefs cover more defect classes for the same review spend. + +## Procedure + +### 1. Orient from the durable task record + +Call `kanban_show` and identify: + +- the original task body and acceptance criteria; +- the latest implementation summary and structured metadata; +- changed files, commit identifiers, and test evidence; +- comments and decisions from earlier runs; +- findings from prior review rounds. + +Treat the handoff as a claim to verify, not as proof that the work is correct. + +### 2. Compare requested behavior with delivered behavior + +Map every acceptance criterion to concrete implementation or output evidence. Note omissions, changed semantics, and unrelated scope before deciding whether to run deeper checks. + +For code work: + +1. Use `read_file` and `search_files` to inspect the changed paths and their callers. +2. Use `terminal` to inspect the diff and run the project's existing focused tests, lint, type checks, or build commands. +3. Exercise the reported failure path and at least one ordinary control path when practical. +4. Check error handling, edge cases, concurrency boundaries, data preservation, security boundaries, and cross-platform behavior relevant to the change. +5. Confirm that tests assert behavior rather than merely snapshotting source text or constants. + +For non-code work: + +1. Inspect the complete deliverable rather than only its summary. +2. Check correctness, completeness, formatting, and provenance. +3. Validate referenced URLs or external facts with the appropriate native tools when they affect the verdict. + +### 3.

Check the schema (step 3) before concluding a field is missing. +- **PATCH vs PUT.** `PATCH` merges supplied fields into the record. `PUT` replaces the record entirely and clears any field you didn't include. Default to `PATCH`. +- **Single-select options must exist.** Writing `"Status": "Shipping"` when `Shipping` isn't in the field's option list errors with `INVALID_MULTIPLE_CHOICE_OPTIONS` unless you pass `"typecast": true` (which auto-creates the option). +- **Per-base token scoping.** A `403` on one base while another works means the token's Access list doesn't include that base — not a scope or auth issue. Send the user to https://airtable.com/create/tokens to grant it. +- **Rate limits are per base, not per token.** 5 req/sec on `baseA` and 5 req/sec on `baseB` is fine; 6 req/sec on `baseA` alone will throttle. Monitor the `Retry-After` header on `429`. + +## Important Notes for Hermes + +- **Always use the `terminal` tool with `curl`.** Do NOT use `web_extract` (it can't send auth headers) or `browser_navigate` (needs UI auth and is slow). +- **`AIRTABLE_API_KEY` flows from `${HERMES_HOME:-~/.hermes}/.env` into the subprocess automatically** when this skill is loaded — no need to re-export it before each `curl` call. +- **Escape curly braces in formulas carefully.** In a heredoc body, `{Status}` is literal. In a shell argument, `{Status}` is safe outside `{...}` brace-expansion context — but pass dynamic strings through `python urllib.parse.quote` before splicing into a URL. +- **Pretty-print with `python -m json.tool`** (always present) rather than `jq` (optional). Only reach for `jq` when you need filtering/projection. +- **Pagination is per-page, not global.** Airtable's 100-record cap is a hard limit; there is no way to bump it. Loop with `offset` until the field is absent. +- **Read the `errors` array** on non-2xx responses — Airtable returns structured error codes like `AUTHENTICATION_REQUIRED`, `INVALID_PERMISSIONS`, `MODEL_ID_NOT_FOUND`, `INVALID_MULTIPLE_CHOICE_OPTIONS` that tell you exactly what's wrong. diff --git a/skills/productivity/box/SKILL.md b/skills/productivity/box/SKILL.md new file mode 100644 index 0000000..a7cac90 --- /dev/null +++ b/skills/productivity/box/SKILL.md @@ -0,0 +1,117 @@ +--- +name: box +description: Box manages cloud files, sharing, search, and metadata. +version: 1.0.0 +author: Chris Kim (iskysun96), Hermes Agent +license: MIT +platforms: [linux, macos, windows] +prerequisites: + commands: [box] +metadata: + hermes: + tags: [Box, Productivity, Cloud Storage, Collaboration, Metadata, Content Extraction, CLI, SDK] + related_skills: [google-workspace] + homepage: https://developer.box.com/ +--- + +# Box + +Use Box as the cloud file system for file operations, collaboration, metadata, and document work.

Do not attempt a global npm install, use `sudo`, change npm's global prefix, or change `PATH`. +- Before OAuth, ask: **“Is Hermes running on the same computer as the browser you will use to authorize Box, or on a remote host such as a VPS, container, or cloud VM?”** Use normal `box login` only for the same-computer path. Use `box login --code` only for the remote/headless path. Do not infer runtime topology from the operating system alone; read [OAuth setup](references/oauth-setup.md) after the user answers. +- Before starting browser authorization, state that Hermes will act as the Box account signed in there. If the user wants narrower access, they can authorize an account that is invited only to the required files, folders, or Hubs. Do not make that account an administrator to unlock an exceptional operation. +- If a custom OAuth Platform App is necessary, use the CLI's interactive Platform App flow.

Then run `box users:get me --json --fields id,name,login` with that runner. + If this succeeds, record the actor and continue. Do not ask about authentication again. Treat `folders:items 0` only as a listing of the actor's root; it is not proof that a shared file, folder, or Hub is inaccessible. For a known file or folder, verify its ID directly; for a Hub, use the Hubs discovery path in [Box Hubs](references/hubs.md). +2. If authentication is absent, ask to connect a Box account with OAuth, then ask whether Hermes and the authorization browser run on the same computer or on separate hosts. Read [OAuth setup](references/oauth-setup.md). +3. Read the relevant reference before operating. Use documented commands first; only run subcommand help when the request needs an option not covered by the reference or the installed CLI rejects the documented form. + +Examples labeled `bash` use POSIX continuation syntax. In PowerShell, run the Box command on one line or replace each trailing `\` with PowerShell's backtick continuation.

Discover an existing accessible Hub first; only create or populate one after the user approves the shared-resource change. If no Hub is available and the user does not want one created, narrow a one-off request with search or metadata. Do not use a Hub for metadata extraction or text generation. Read [Box Hubs](references/hubs.md). + +When the user asks to extract metadata from a Box file, treat it as a request to persist the result unless they ask for a preview. Use structured extraction with inline fields when the desired schema is known and freeform extraction when the fields are exploratory. Reuse a compatible existing enterprise template when one represents every requested field. Otherwise store flat scalar results in the built-in `global.properties` metadata instance, or upload a JSON sidecar beside the source file when the result contains nested objects, tables, or values that must retain their types. Read every write back and compare it with the intended result. Never silently substitute a file description, attach a partial or unrelated template, truncate fields, or discard fields. + +Do not create or change metadata templates. Box does not permit creation of global templates, and enterprise-template administration is outside Hermes' normal OAuth content workflow. If the user needs reusable typed enterprise metadata and no compatible template exists, explain that a Box Admin or authorized Co-Admin must create it separately, leave existing structured metadata unchanged, and report the persisted `global.properties` instance or JSON sidecar instead. Read [Search and AI](references/search-and-ai.md) for the complete extraction and writeback workflow. + +Before the first Box AI request, state that Box AI must be enabled, consumes AI units, and remains limited to the current actor's permissions; do not wait for acknowledgement. An AI response returned to Hermes can still contain sensitive information. Confirm only when a material batch's file scope or expected AI-unit use is ambiguous, or when the user has not explicitly requested that scale.

Box does not allow creation in the `global` scope. Enterprise templates can only be created by a Box Admin or a Co-Admin granted template-management permission, and custom templates may depend on the account plan. Template administration is outside Hermes' normal OAuth content workflow. + +Choose extraction based on the request, not on template availability: + +- For known fields, run `ai:extract-structured` with inline `--fields`; this preserves a predictable typed JSON result without creating a template. +- For exploratory or variable fields, run `ai:extract` with a precise prompt. + +Persist a flat scalar result in Box's built-in `global.properties` instance. It accepts schema-free properties without creating a template. Convert each value to a lossless string representation, validate keys before writing, and preserve unrelated existing properties. If the instance does not exist, create it. If it exists, use `--replace` for existing keys and `--add` for new keys. + +```bash +box files:metadata:get --scope global --template-key properties --json + +box files:metadata:create --scope global --template-key properties \ + --data "invoice_number=INV-001" --data "total=1250.00" --json + +box files:metadata:update --scope global --template-key properties \ + --replace "invoice_number=INV-001" --add "total=1250.00" --json + +box files:metadata:get --scope global --template-key properties --json +``` + +`global.properties` is untyped and cannot be queried with the Metadata Query API. For nested objects, tables, arrays, or any result whose JSON types must remain intact, write the complete extraction response to a UTF-8 JSON sidecar named `..metadata.json` and upload it to the source file's parent folder. If that exact sidecar already exists for the workflow, upload a new version rather than creating a duplicate. Fetch the uploaded file and compare its content or checksum with the local JSON, then report both the source and sidecar IDs and links. + +If the user explicitly requires reusable typed enterprise metadata, explain that an administrator must create a compatible enterprise template separately. Do not elevate the connected account or switch to an administrator identity. Preserve the extraction through `global.properties` or a JSON sidecar in the meantime, and never silently truncate or discard fields. + +### File descriptions are not metadata fallback + +**Hard rule:** Never use a file description as an automatic substitute for extracted metadata. Treat 255 characters as the safe limit because Box can truncate longer descriptions. Use `box files:update --description` only when the user explicitly requests a description, first verify the complete intended text fits, then read it back and compare it with the intended value. + +## Confidentiality and AI units + +Box AI processes source files through Box's governed AI integration instead of downloading source bodies into Hermes' coding-model context. Box AI responses returned to Hermes can still contain confidential information. Do not claim that no third-party model provider is involved or that content can never be used for training; follow Box's current trust and plan documentation. + +Before the first Box AI request, explain that Box AI must be enabled, calls consume AI units, and answers remain constrained by the current actor's permissions. For a material batch, state the file count and ask for confirmation. Do not promise a unit balance or per-call cost unless Box exposes it for the current account. + +If Box AI is unavailable or out of units, offer existing metadata/search, a smaller sample, enabling units, or explicit approval for local/external analysis. Never silently fall back to downloading files for an external model. + +## Scale + +Use `--bulk-file-path` where the command supports it. For hundreds of files, inventory first, sample the schema, confirm unit-consuming scope, and use [Bulk operations](bulk-operations.md). For recurring, high-throughput extraction, evaluate Box Extract rather than simulating a folder-wide workflow through repeated downloads. + +## Sources + +- [Box AI API](https://developer.box.com/ai/box-ai-api/) +- [Structured metadata extraction](https://developer.box.com/guides/box-ai/ai-tutorials/extract-metadata-structured/) +- [Metadata template scopes](https://developer.box.com/guides/metadata/scopes/) +- [Global metadata query limitation](https://developer.box.com/guides/metadata/queries/limitations/) +- [Box AI trust](https://www.box.com/ai/trust/) +- [AI units and plan access](https://support.box.com/hc/en-us/articles/45612941554835-Expanded-AI-API-Access-and-AI-Units-for-Business-Business-Plus-and-Enterprise-Plans) +- [Metadata template permissions](https://developer.box.com/guides/metadata/templates/create/) diff --git a/skills/productivity/box/references/troubleshooting.md b/skills/productivity/box/references/troubleshooting.md new file mode 100644 index 0000000..7465178 --- /dev/null +++ b/skills/productivity/box/references/troubleshooting.md @@ -0,0 +1,33 @@ +# Troubleshooting + +Capture the actor, object ID and type, exact command, status code, and safe error body before changing approach. + +## First checks + +```bash +box users:get me --json --fields id,name,login +box configure:environments:list +box files:get --json --fields id,name,parent +box folders:get --json --fields id,name,parent +box hubs --scope all --max-items 1000 --json +box hubs:get --json +``` + +Confirm the current actor, resource type, ID, resource-specific collaboration, app scopes, and selected environment.

Pass `-o out.docx` to keep + the original; omit it to edit in place. Paragraph indices for + `insert`/`delete`/`style`/`toc` refer to `--structure`/`--text` body + order. Run `normalize` first on documents that came out of heavy Word + editing — it merges adjacent runs with identical formatting so later + find-replace matches reliably. +4. **Review revisions.** `docx_revisions.py list` reports every `w:ins` + and `w:del` (id, author, date, affected text) anywhere in body, + tables, headers, or footers. `accept-all` / `reject-all` resolve them + in bulk; `accept`/`reject --id N` handles a single revision. Accept + keeps insertions and drops deleted text; reject does the reverse. +5. **Comments.** `docx_comments.py list` returns each comment's id, + author, date, body text, and the document text it is anchored to. + `add --target "some phrase"` anchors a new comment to the first + occurrence of that phrase (runs are split as needed; formatting is + preserved). `delete --id N` removes the comment and its markers + without touching document text. +6. **Template.** Put `{{name}}`-style tokens in the document. Run + `scripts/docx_template.py` with a JSON object of values. Use + `--strict` to fail when tokens remain unfilled; the JSON output lists + `filled` counts and `unfilled_tokens` either way. +7. **Verify** (always): re-read the output with `--text` or + `--structure`, and run `docx_validate.py` on anything you produced + via revision/comment surgery. + +## Converting to PDF + +No script needed.

Create or select a project: +> https://console.cloud.google.com/projectselector2/home/dashboard +> 2. Enable the required APIs from the API Library: +> https://console.cloud.google.com/apis/library +> Enable: Gmail API, Google Calendar API, Google Drive API, +> Google Sheets API, Google Docs API, People API +> 3. Create the OAuth client here: +> https://console.cloud.google.com/apis/credentials +> Credentials → Create Credentials → OAuth 2.0 Client ID +> 4. Application type: "Desktop app" → Create +> 5. If the app is still in Testing, add the user's Google account as a test user here: +> https://console.cloud.google.com/auth/audience +> Audience → Test users → Add users +> 6. Download the JSON file and tell me the file path +> +> Important Hermes CLI note: if the file path starts with `/`, do NOT send only the bare path as its own message in the CLI, because it can be mistaken for a slash command. Send it in a sentence instead, like: +> `The JSON file path is: ~/Downloads/client_secret_....json` + +Once they provide the path: + +```bash +$GSETUP --client-secret /path/to/client_secret.json +``` + +If they paste the raw client ID / client secret values instead of a file path, +write a valid Desktop OAuth JSON file for them yourself, save it somewhere +explicit (for example `~/Downloads/hermes-google-client-secret.json`), then run +`--client-secret` against that file. + +### Step 3: Get authorization URL + +Use the service set chosen in Step 1. Examples: + +```bash +$GSETUP --auth-url --services email,calendar --format json +$GSETUP --auth-url --services calendar,drive,sheets,docs --format json +$GSETUP --auth-url --services all --format json +``` + +This returns JSON with an `auth_url` field and also saves the exact URL to +`~/.hermes/google_oauth_last_url.txt`. + +Agent rules for this step: +- Extract the `auth_url` field and send that exact URL to the user as a single line. +- Tell the user that the browser will likely fail on `http://localhost:1` after approval, and that this is expected. +- Tell them to copy the ENTIRE redirected URL from the browser address bar. +- If the user gets `Error 403: access_denied`, send them directly to `https://console.cloud.google.com/auth/audience` to add themselves as a test user. + +### Step 4: Exchange the code + +The user will paste back either a URL like `http://localhost:1/?code=4/0A...&scope=...` +or just the code string. Either works. The `--auth-url` step stores a temporary +pending OAuth session locally so `--auth-code` can complete the PKCE exchange +later, even on headless systems: + +```bash +$GSETUP --auth-code "THE_URL_OR_CODE_THE_USER_PASTED" --format json +``` + +If `--auth-code` fails because the code expired, was already used, or came from +an older browser tab, it now returns a fresh `fresh_auth_url`. In that case, +immediately send the new URL to the user and have them retry with the newest +browser redirect only. + +### Step 5: Verify + +```bash +$GSETUP --check +``` + +Should print `AUTHENTICATED`. Setup is complete — token refreshes automatically from now on. + +### Notes + +- Token is stored at `~/.hermes/google_token.json` and auto-refreshes. +- Pending OAuth session state/verifier are stored temporarily at `~/.hermes/google_oauth_pending.json` until exchange completes. +- If `gws` is installed, `google_api.py` points it at the same `~/.hermes/google_token.json` credentials file. Users do not need to run a separate `gws auth login` flow. +- To revoke: `$GSETUP --revoke` + +## Usage + +All commands go through the API script.

Check `encrypted` (if true, decrypt first with `pdf_secure.py --decrypt`) and `likely_scanned_pages`. If pages are image-only, export them with `pdf_page_image.py --pages --dpi 300 --out-dir imgs/` and hand the PNGs to the `references/ocr-extraction.md` skill — do not report empty text as "no content". +2. **Create.** Write a JSON spec with `write_file` (elements: `heading`, `paragraph`, `table`, `image`, `pagebreak`; optional `title`/`author` metadata; page numbers are added automatically), then run `pdf_create.py`. Verify visually with `vision_analyze` on a rendered page image if layout matters. +3. **Extract.** `--text` gives a JSON list of per-page strings; `--tables` gives row arrays per page and can also emit CSV files. Read results with `read_file`; never eyeball a binary PDF directly. +4. **Manipulate.** `pdf_merge.py` concatenates and can add one bookmark per source file; `pdf_split.py` handles page ranges (1-based, e.g. `1-3,5,9-`), rotation in 90° steps, and `--compress`. Watermark by preparing a single-page stamp PDF (e.g. via `pdf_create.py`) and overlaying it with `pdf_watermark.py`; for one-liner stamps ("sign here", diagonal DRAFT, corner labels) use `pdf_stamp.py` with text or an image at explicit coordinates. +5. **Build forms.** Write one form-spec JSON (fields with `label_box`/`entry_box` in PDF points — see `references/forms.md`), lint it with `pdf_form_layout.py` and fix every reported problem, optionally review the `--render-overlay` PNG with `vision_analyze`, then build with `pdf_make_form.py` and confirm with `pdf_read.py --fields`. +6. **Fill forms.** List fields (`--fields`) to learn exact names and types, write a UTF-8 JSON of `{"FieldName": "value"}` with `write_file` (checkboxes accept `true`/`false`; radio/choice values must match the field's export options), then `pdf_fill_form.py`. Re-read with `--fields` to confirm values landed. +7. **Metadata & attachments.** `pdf_meta.py --set-meta` writes Title/Author/Subject/Keywords (DocInfo); `--clear-meta` drops them; `--attach`/`--list-attachments`/`--extract-attachments` round-trip embedded files. +8. **Secure.** Encrypt with distinct user/owner passwords and AES-256. To remove a password you know, `--decrypt` writes an unencrypted copy. +9. **Verify** (see below) before reporting success. + +## Pitfalls + +- **Scanned PDFs**: empty `extract_text()` plus page images means there is no text layer. Route to `references/ocr-extraction.md`; do not fabricate text. +- **Flattening limits**: `pdf_fill_form.py --flatten` uses pypdf's flatten support, which converts widget appearances into page content. It is reliable for plain text fields and checkboxes but can drop or misrender exotic widgets (rich text, custom appearance streams, some radio groups). Verify the flattened output visually with `vision_analyze`; for bulletproof flattening use an external renderer (e.g. Ghostscript or `pdftoppm`+reassembly) as a fallback. +- **NeedAppearances**: after filling, viewers only render values if appearance streams exist. The fill script sets the AcroForm `NeedAppearances` flag so conforming viewers regenerate them; some minimal viewers ignore it — flatten if display fidelity matters. +- **Non-Latin form values**: values are stored correctly (UTF-16), but the field's default font may lack glyphs, so a viewer can show blanks even though the data round-trips. Verify with `--fields`, not just visually. +- **Compression expectations**: `--compress` only deflates content streams. Typical savings are 0–20%; it does nothing for PDFs dominated by images or already-compressed streams. It is not a substitute for image downsampling (Ghostscript territory). +- **Permission flags don't enforce**: owner-password permission bits (no-print, no-copy) are polite requests that viewers may honor; any library (including pypdf) can read and strip them. Only the user password actually gates content via encryption. Never present permission flags as security. +- **Table extraction is heuristic**: pdfplumber detects tables from ruling lines/word alignment; borderless or merged-cell tables may need `table_settings` tuning or manual cleanup. +- **Page indexing**: helper CLIs take 1-based pages; pypdf APIs are 0-based. The scripts convert — don't double-convert. +- **Rotated stamp text extraction**: pdfplumber's line grouping scrambles rotated glyphs (a 45° "DRAFT" extracts as stray letters); verify rotated stamps with `pypdf`'s `extract_text()` or a rendered image instead. +- **Radio groups**: reportlab needs ≥2 `radio()` widgets per group, fills need the slashed export value (`"/red"`), and flatten fidelity is worst for radios — see `references/forms.md`. +- **Metadata scope**: `pdf_meta.py` writes the classic DocInfo dictionary only; embedded XMP metadata (if any) is left untouched and may show different values in some viewers. +- **PDF/A is out of scope**: pypdf/reportlab cannot produce or validate conformant PDF/A. If archival conformance is required, run Ghostscript via the `terminal` tool (e.g. `gs -dPDFA=2 -dPDFACompatibilityPolicy=1 -sColorConversionStrategy=UseDeviceIndependentColor -sDEVICE=pdfwrite -o out.pdf in.pdf` with a suitable ICC profile) and validate with veraPDF — both are external installs, and the result still needs validation, not assumption. +- Rotation must be a multiple of 90; encrypted inputs must be decrypted before any other operation. + +## Verification + +- After create/merge/split: `pdf_read.py out.pdf --meta` — confirm `page_count`, and per-page `rotation` when you rotated. +- After extraction: check the JSON is non-empty and spot-check a known string or cell. +- Form design loop: `pdf_form_layout.py spec.json` must exit 0; then `--render-overlay boxes.png --pdf form.pdf` and review the PNG with `vision_analyze` (red = entry boxes with field names, blue = label boxes) asking about overlaps, misalignment, and labels detached from their fields.

Create a deck + +Write a JSON spec (see `pptx_create.py --help` for the full format), then +run `pptx_create.py`. Per slide you can set: `layout` (title, +title_content, section, two_content, title_only, blank), `title`, +`subtitle`, `bullets` (strings, or dicts with `level` 0-4, `size` pt, +`bold`, `italic`, `font`, `color` hex, `link` URL for a hyperlink), +`background` (solid hex), `footer` (text; enables the layout's footer +placeholder), `slide_number` (true; enables the layout's slide-number +placeholder), `images` (path + left/top/width/height in inches), `tables` +(`rows` as list-of-lists), `shapes` (rectangle, rounded_rectangle, oval, +diamond, right_arrow, chevron, with `fill` hex + optional `text`), +`charts` (bar, bar_h, line, pie with `categories` + `series`), and +`notes` (speaker notes). + +### 2. Read a deck + +`pptx_read.py deck.pptx --outline` returns slide size, layout inventory, +and per slide: layout name, all shape texts, table cells, image inventory +(filename/ext/bytes), chart categories/series/values, and speaker notes. +Use `--images DIR` to dump embedded pictures to files, then +`vision_analyze` on any exported image if you need to see its content. + +### 3. Edit a deck + +`pptx_edit.py` combines operations in one pass; use `--output` to keep the +original. Text replacement scans slide shapes, table cells, and notes. +Image swap retargets the picture's relationship id so position and size +are preserved. Slide removal drops the relationship and the `` +entry; reorder moves the `` element within `` +(python-pptx has no public API for either — the script does the XML-level +work). `--duplicate-slide N` appends an independent deep copy of slide N: +shape XML plus image/media/hyperlink relationships are cloned and rIds +remapped, so editing the copy never touches the original. Chart slides +are refused (see Pitfalls). `--set-notes`/`--append-notes` edit speaker +notes; `--set-background`, `--hyperlink`, `--enable-slide-number`, and +`--set-footer` handle deck polish. + +Chart updates take a JSON spec via `--chart-data`. Full replace: +`{"slide": 0, "chart": 0, "categories": [...], "series": {...}}`. For +surgical edits, pass `"ops"` instead — a list of +`{"op": "update_series", "name": ..., "values": [...]}`, +`add_series`, `remove_series`, `rename_category` (`from`/`to` or +`index`), and `set_title`. python-pptx can only swap a chart's entire +dataset (`replace_data`), so ops are implemented as read-existing → +modify → replace; the per-part UX is a wrapper, and any chart data not +expressible as categories + numeric series will be normalized by the +round-trip. + +### 4. Build from a template + +`pptx_from_template.py` opens a brand .pptx, replaces every +`{{token}}` from a values JSON across slides/tables/notes, and can append +new slides that use the template's own layouts (by layout name or index) +so they inherit the master's fonts and colors. Tip: to start from a +template with zero slides, delete existing ones afterward with +`pptx_edit.py --remove-slide`. + +### 5. Visual verification + +`pptx_render.py deck.pptx --outdir ./render` converts the deck to PDF +with `soffice --headless` and splits it into one PNG per slide with +`pdftoppm` (or `pdftocairo`). Output JSON lists the PNG paths — review +each with `vision_analyze`. When either tool is missing the script exits +0 with `{"rendered": false, "missing": [...]}` and guidance; fall back to +the JSON outline from `pptx_read.py`, which verifies content and +structure, just not visuals. + +## Converting to PDF + +If LibreOffice is installed, export the finished deck to PDF directly: + +```bash +soffice --headless --convert-to pdf --outdir ./out deck.pptx +``` + +The output lands at `./out/deck.pdf`. Fonts not installed on the host are +substituted, so render-verify (Procedure step 5) before shipping the PDF. +There is no offline pure-Python .pptx→PDF path; if `soffice` is absent, +say so rather than approximating. + +## Pitfalls + +- **Run splitting**: PowerPoint fragments paragraph text into runs at + spell-check and edit boundaries. `--replace-text` first merges adjacent + runs whose formatting is identical, so matches split across such runs + are replaced with formatting fully preserved. Only when a match spans + *genuinely differently-formatted* runs is the paragraph rewritten with + the first run's formatting — verify those slides after replacement. +- **Chart slides cannot be duplicated**: each chart relationship embeds a + separate XLSX workbook part; cloning that graph reliably is not + supported, so `--duplicate-slide` refuses chart slides cleanly instead + of corrupting the deck. Rebuild the chart on a new slide instead. + External-hyperlink and image/media rels are carried over; layout and + notes rels are recreated fresh. +- **Chart ops are a wrapper**: python-pptx replaces the whole dataset; + `"ops"` round-trips existing plot data through `replace_data`, and + changing chart *type* is not possible. +- **Reordering is XML-level**: python-pptx has no supported reorder API. + `--move-slide` manipulates `` directly; safe for ordinary + decks but re-read the deck afterward to confirm. +- **Copying slides between decks is unsupported** — duplication works + only within one deck, where layouts and masters are shared. +- Footer/slide-number enablement copies the placeholder from the slide's + layout; on layouts without those placeholders, `--set-footer` fails + with a clear message (add a textbox instead). +- Hyperlinks apply to whole runs; `--hyperlink` links every run + containing the given text on that slide. +- The default python-pptx template is 4:3; the create script sets 16:9 + unless the spec says otherwise. Custom templates keep their own size. +- Layout indexes vary by template. For brand templates, list layout names + first: `pptx_read.py template.pptx --outline` (`layouts_available`). +- `slide.shapes.title` is None on blank layouts — the create script + handles this, but remember it when writing ad-hoc python-pptx code. +- Always pass `encoding="utf-8"` when writing spec files; tokens like + `{{city}}` may be filled with non-ASCII values. + +## Verification + +1. After any create/edit, run `pptx_read.py OUT.pptx --outline` and check + slide count, texts, tables, notes, and chart values match intent. +2. `--images DIR` then file-size check confirms pictures embedded. +3. Render every slide with `pptx_render.py deck.pptx --outdir ./render` + and review each PNG with `vision_analyze` — this catches overlapping + shapes, truncated text, and color problems the outline cannot. If the + render tools are missing, the script says so; rely on the outline. +4. The bundled test suite is the full contract: + `python -m pytest tests/ -q` (requires python-pptx + pytest). diff --git a/skills/productivity/powerpoint/scripts/pptx_create.py b/skills/productivity/powerpoint/scripts/pptx_create.py new file mode 100644 index 0000000..71d1876 --- /dev/null +++ b/skills/productivity/powerpoint/scripts/pptx_create.py @@ -0,0 +1,214 @@ +#!/usr/bin/env python3 +"""Create a .pptx presentation from a JSON deck spec. + +Spec format (all positions/sizes in inches, colors as RRGGBB hex): +{ + "slide_size": "16:9", // or "4:3" (default "16:9") + "slides": [ + {"layout": "title", "title": "My Deck", "subtitle": "Q3 review"}, + {"layout": "title_content", "title": "Agenda", + "bullets": ["Top item", + {"text": "Sub item", "level": 1, "bold": true, + "size": 18, "color": "CC0000", "font": "Arial", + "italic": false, + "link": "https://example.com/agenda"}], + "background": "1F2937", // solid slide background (hex) + "footer": "Confidential", // footer placeholder text + "slide_number": true, // enable slide-number placeholder + "notes": "Speaker notes for this slide"}, + {"layout": "blank", "title": "Widgets", + "images": [{"path": "logo.png", "left": 1, "top": 1, "width": 3}], + "tables": [{"left": 1, "top": 2, "width": 6, "height": 2, + "rows": [["H1", "H2"], ["a", "b"]]}], + "shapes": [{"type": "rounded_rectangle", "left": 8, "top": 1, + "width": 3, "height": 1, "fill": "4472C4", + "text": "Callout", "text_color": "FFFFFF"}], + "charts": [{"type": "bar", "left": 1, "top": 3, "width": 6, + "height": 3.5, "title": "Sales", + "categories": ["Q1", "Q2"], + "series": {"North": [10, 20], "South": [7, 13]}}]} + ] +} +Layouts: title, title_content, section, two_content, title_only, blank +Chart types: bar, bar_h, line, pie Shape types: rectangle, +rounded_rectangle, oval, diamond, right_arrow, chevron +""" +import argparse +import copy +import json +import sys + +from pptx import Presentation +from pptx.chart.data import CategoryChartData +from pptx.dml.color import RGBColor +from pptx.enum.chart import XL_CHART_TYPE +from pptx.enum.shapes import MSO_SHAPE +from pptx.util import Inches, Pt + +LAYOUTS = {"title": 0, "title_content": 1, "section": 2, + "two_content": 3, "title_only": 5, "blank": 6} +CHART_TYPES = {"bar": XL_CHART_TYPE.COLUMN_CLUSTERED, + "bar_h": XL_CHART_TYPE.BAR_CLUSTERED, + "line": XL_CHART_TYPE.LINE_MARKERS, + "pie": XL_CHART_TYPE.PIE} +SHAPE_TYPES = {"rectangle": MSO_SHAPE.RECTANGLE, + "rounded_rectangle": MSO_SHAPE.ROUNDED_RECTANGLE, + "oval": MSO_SHAPE.OVAL, "diamond": MSO_SHAPE.DIAMOND, + "right_arrow": MSO_SHAPE.RIGHT_ARROW, + "chevron": MSO_SHAPE.CHEVRON} + + +def style_run(run, spec): + """Apply font styling from a bullet/text spec dict to a run.""" + font = run.font + if spec.get("size"): + font.size = Pt(spec["size"]) + if spec.get("bold") is not None: + font.bold = spec["bold"] + if spec.get("italic") is not None: + font.italic = spec["italic"] + if spec.get("font"): + font.name = spec["font"] + if spec.get("color"): + font.color.rgb = RGBColor.from_string(spec["color"]) + if spec.get("link"): + run.hyperlink.address = spec["link"] + + +def add_bullets(text_frame, bullets): + text_frame.clear() + for i, item in enumerate(bullets): + if isinstance(item, str): + item = {"text": item} + para = text_frame.paragraphs[0] if i == 0 else text_frame.add_paragraph() + para.level = int(item.get("level", 0)) + run = para.add_run() + run.text = item.get("text", "") + style_run(run, item) + + +def copy_layout_placeholder(slide, ph_idx): + """Copy a layout placeholder (footer=11, slide number=12) onto the + slide so it actually renders;

If the job doesn't exist at all, check `subscriptions` — the webhook may have expired (see pitfall below). +- User asks "is setup working?" → `validate`, then `token-health`, then `subscriptions`. If all three pass, request a test meeting and check `list` for a fresh row. +- User asks "re-run summary for meeting X" → `list` to find the job ID, `run ` to replay. If it fails again, `show ` to inspect the error and `fetch --meeting-id` to dry-run the artifact resolution. +- User asks "add meeting X to the pipeline" → usually you don't — the pipeline is subscription-driven, not per-meeting. If they want a specific past meeting summarized, use `fetch` to pull transcript + `run` after a job is created. + +## Critical pitfall: Graph subscriptions expire in 72 hours + +Microsoft Graph caps webhook subscriptions at 72 hours and **will not auto-renew them**. If `maintain-subscriptions` is not scheduled, meeting notifications silently stop arriving 3 days after any manual subscription creation. + +When the user reports "the pipeline worked yesterday but nothing is arriving today": +1. Run `hermes teams-pipeline subscriptions` — if it's empty or all entries show `expirationDateTime` in the past, that's the cause. +2. Recreate with `subscribe` as shown above. +3. **Set up automated renewal immediately** via `hermes cron add`, a systemd timer, or plain crontab. The operator runbook at `/docs/guides/operate-teams-meeting-pipeline#automating-subscription-renewal-required-for-production` has all three options. 12-hour interval is safe (6x headroom against the 72h limit). + +## Other pitfalls + +- **Transcript not available yet.** Teams takes some time after a meeting ends to generate the transcript artifact. `fetch --meeting-id` on a just-ended meeting may return empty. Wait 2-5 minutes and retry, or let the Graph webhook drive ingestion naturally. +- **Delivery mode mismatch.** If summaries are produced (`list` shows success) but nothing lands in Teams, check `platforms.teams.extra.delivery_mode` and the matching target config (`incoming_webhook_url` OR `chat_id` OR `team_id`+`channel_id`). The writer reads these from config.yaml or `TEAMS_*` env vars. +- **Graph app permissions.** A token acquires cleanly (`token-health` passes) but Graph API calls return 401/403 when permissions were added but admin consent wasn't re-granted. Have the user revisit the app registration in the Azure portal and click "Grant admin consent" again. + +## Related docs + +Point the user to these when they need more depth than this skill covers: +- Azure app registration walkthrough: `/docs/guides/microsoft-graph-app-registration` +- Full pipeline setup: `/docs/user-guide/messaging/teams-meetings` +- Operator runbook (renewal automation, troubleshooting, go-live checklist): `/docs/guides/operate-teams-meeting-pipeline` +- Webhook listener setup: `/docs/user-guide/messaging/msgraph-webhook` diff --git a/skills/productivity/weekly-review-planning/SKILL.md b/skills/productivity/weekly-review-planning/SKILL.md new file mode 100644 index 0000000..fb62cd8 --- /dev/null +++ b/skills/productivity/weekly-review-planning/SKILL.md @@ -0,0 +1,81 @@ +--- +name: weekly-review-planning +description: "Weekly reset: commitments, stalled work, next-week plan." +version: 0.1.0 +author: Ben Barclay (benbarclay), Hermes Agent +license: MIT +platforms: [linux, macos, windows] +metadata: + hermes: + tags: [Weekly-Review, Planning, Tasks, Calendar, Productivity] + related_skills: [obsidian, notion, airtable, google-workspace, email-inbox-triage] +--- + +# Weekly Review and Planning + +Run a bounded weekly reset across the user's chosen systems.

Each sheet supports + `rows` (scalars or styled cell objects), sparse `cells` overrides, + `column_widths`, `row_heights`, `merges`, `freeze_panes`, + `autofilter`, `conditional_formats` (cell_is rules and color + scales), `charts` (bar/line/pie from cell ranges), + `validations` (list dropdowns), `tables` (native Excel tables with + a style name), and `protection`. Workbook-level `defined_names` + maps names to refs. Cell objects also take `hyperlink` and `note`. + Typed values: JSON numbers/bools + pass through; dates use `{"value": "2026-01-31", "type": "date"}`. + Number formats are Excel format strings: currency `"$#,##0.00"`, + percent `"0.0%"`, date `"yyyy-mm-dd"`. +2. **Formulas**: set with `"formula": "SUM(B2:B9)"` in the spec or + `--set "C1==SUM(A:A)"` in the editor. When writing formulas, add + `"full_calc_on_load": true` (spec) or `--recalc` (editor); this sets + the workbook's `fullCalcOnLoad` flag so Excel/LibreOffice recompute + everything on open. openpyxl itself NEVER evaluates formulas. +3. **Read**: `--sheets` for inventory (names, dimensions, merged + ranges, chart count, tables, protection, defined names), + `--json`/`--csv` for data, `--formulas` to + pair each formula string with its cached result, `--notes` for + cell comments, `--names` for defined names. Cached results + exist only if the file was last saved by a real spreadsheet app; + files fresh from openpyxl return `null` there. To materialize + results headlessly run `xlsx_recalc.py file.xlsx` (uses + LibreOffice; prints `{"recalculated": false, ...}` and exits 0 + when `soffice` is absent), then reload with `--data-only`. +4. **Edit**: `xlsx_edit.py` applies renames/copies first, then + structural row/column changes, then `--set`/`--append`. It edits in + place unless `--out` is given — copy the file first if you need the + original. +5. **Restructure**: for insert/delete on sheets that have formulas, + merges, tables, or filters, use `xlsx_restructure.py` instead of + `xlsx_edit.py`. It rewrites formula references on ALL sheets + (absolute `$` refs, ranges, cross-sheet refs), shifts merges, + autofilter, freeze panes, validation and conditional-format + ranges, table refs, defined names, and row/column dimensions, then + prints a JSON report including a `not_shifted` list. Rules and + limits: `references/restructuring.md`. +6. **CSV interop**: `csv_to_xlsx.py` infers int/float/bool/ISO-date + per cell and styles the header row; `xlsx_to_csv.py` writes ISO + dates and blank strings for empty cells. Both default to UTF-8 and + accept `--encoding` (e.g. `utf-8-sig` for Excel-friendly BOM, + `cp1252` for legacy Windows exports). + +## Converting to PDF + +LibreOffice converts headlessly (also works for CSV export of a single +sheet): + +```bash +soffice --headless --convert-to pdf report.xlsx --outdir out/ +soffice --headless --convert-to csv report.xlsx --outdir out/ # 1st sheet only +``` + +Only the first sheet lands in a CSV; for other sheets use +`xlsx_to_csv.py --sheet NAME`. If `soffice` is missing, install +LibreOffice or hand the file to the user unconverted. + +## Pitfalls + +- **openpyxl does not calculate.** Formula results are available only + via `load_workbook(path, data_only=True)` and only when the file was + previously saved by Excel/LibreOffice. Otherwise you get `None`. +- **`xlsx_edit.py` insert/delete does not shift references** (raw + openpyxl behavior). Use `xlsx_restructure.py`, which does — but even + it cannot move chart anchors, images, or conditional-format RULE + formulas; read its JSON report's `not_shifted` list and + `references/restructuring.md`. +- **Sheet protection is NOT security.** `--protect` sets the standard + xlsx sheet-protection hash: it signals "don't edit this" to + well-behaved apps and nothing more. Anyone can strip it by editing + the zip's XML or unchecking it in LibreOffice. Never rely on it for + confidentiality or integrity; it does not encrypt anything. +- **`data_only=True` then save** silently discards all formulas + (cached values replace them). Never save a workbook loaded that way + unless that is the goal. +- **Loading strips charts/images**: openpyxl does not round-trip + charts, so editing a charted workbook and saving drops the charts. + Re-add charts after editing, or avoid re-saving charted files. +- **CSV locale traps**: always pass explicit encodings (the scripts + already do) and remember European CSVs often use `;` delimiters and + decimal commas — use `--delimiter ';'` and expect strings like + `"12,5"` to stay strings. +- **Dates are datetimes**: Excel stores dates as serial numbers; + openpyxl returns `datetime`/`date` objects.

Do this *before* writing +prose. Registering later, from memory, is the failure mode this skill exists to +prevent. + +③ **Write cite-while-drafting.** Place the bracketed id(s) immediately after +each sentence the source supports: + +``` +Ice floats because it is less dense than liquid water.[1][2] +``` + +- No space before the bracket; each id in its own brackets. +- Max 3 ids per sentence.

If absent, install with +`hermes skills install official/social-media/reddit-reading` or +`hermes skills install official/research/rss-feeds` before using them. + +Register every URL from every route in the ledger as it arrives (step ②). Keep +opinion and measurement apart: a Reddit thread is evidence that users *report* +something, not that it is true; pair it with a primary source or label it as +sentiment. Report per-platform coverage gaps ("Reddit search returned nothing +newer than March") rather than silently narrowing to what worked. + +## Fact-Checking Mode + +For work where the reader must be able to check the chain — medical, legal, +financial, safety, disputed claims, or when the user asks for fact-checking — +upgrade from citations to evidence: + +① **Attach a verbatim quote per source.** After extracting a page, save its +text to a file and attach the sentence(s) that carry each claim: + +```bash +python "$S" quote 1 --text "Ice is about 9% less dense than liquid water." --from page1.txt +``` + +The quote is rejected unless it appears verbatim in the evidence text +(insensitive to whitespace, case, and markdown markup — inline links like +`_[ERAP1](https://…)_` in extracted text match the plain prose a reader sees), +so a paraphrase or misremembered figure cannot masquerade as evidence. +Copy-paste from the fetched text; never retype. Quote the sentence as the +reader sees it — the matcher sees through the extractor's markup for you, so +you don't have to reproduce link syntax or escaped asterisks in your quote. + +② **Flag model-knowledge claims with `[unverified]`.** A load-bearing claim +you could not source gets an explicit marker instead of a citation: + +``` +The refactor likely predates the 2.0 release.[unverified] +``` + +`verify --min-coverage` counts `[unverified]` sentences as covered — the goal +is declared provenance for every claim, not a citation on every sentence. +If a key claim can be checked, check it; `[unverified]` is for what genuinely +cannot be, and a fact-check deliverable dominated by `[unverified]` markers +should say so in its summary. + +③ **Cross-check disputed facts against a second independent source.** When two +sources disagree, cite both readings with their own ids and quotes, and say +which you weight and why. One source is reporting; two independent sources are +corroboration. + +④ **Verify with the evidence gate and render the evidence block:** + +```bash +python "$S" verify report.md --evidence --min-coverage 0.5 +python "$S" render --style evidence --replace-in report.md +``` + +`--evidence` fails the draft if any cited source has no attached quote. The +`evidence` render style prints each source's quotes beneath its URL, so the +deliverable shows claim → source → exact supporting text with nothing taken on +faith.

pattern](https://gist.github.com/karpathy/442a6bf555914893e9891c11519de94f). + +Unlike traditional RAG (which rediscovers knowledge from scratch per query), the wiki +compiles knowledge once and keeps it current. Cross-references are already there. +Contradictions have already been flagged. Synthesis reflects everything ingested. + +**Division of labor:** The human curates sources and directs analysis. The agent +summarizes, cross-references, files, and maintains consistency. + +## When This Skill Activates + +Use this skill when the user: +- Asks to create, build, or start a wiki or knowledge base +- Asks to ingest, add, or process a source into their wiki +- Asks a question and an existing wiki is present at the configured path +- Asks to lint, audit, or health-check their wiki +- References their wiki, knowledge base, or "notes" in a research context + +## Wiki Location + +**Location:** Set via `WIKI_PATH` environment variable (e.g. in `${HERMES_HOME:-~/.hermes}/.env`). + +If unset, defaults to `~/wiki`. + +```bash +WIKI="${WIKI_PATH:-$HOME/wiki}" +``` + +The wiki is just a directory of markdown files — open it in Obsidian, VS Code, or +any editor.

The agent reads but never modifies these. +**Layer 2 — The Wiki:** Agent-owned markdown files. Created, updated, and +cross-referenced by the agent. +**Layer 3 — The Schema:** `SCHEMA.md` defines structure, conventions, and tag taxonomy. + +## Resuming an Existing Wiki (CRITICAL — do this every session) + +When the user has an existing wiki, **always orient yourself before doing anything**: + +① **Read `SCHEMA.md`** — understand the domain, conventions, and tag taxonomy. +② **Read `index.md`** — learn what pages exist and their summaries. +③ **Scan recent `log.md`** — read the last 20-30 entries to understand recent activity. + +```bash +WIKI="${WIKI_PATH:-$HOME/wiki}" +# Orientation reads at session start +read_file "$WIKI/SCHEMA.md" +read_file "$WIKI/index.md" +read_file "$WIKI/log.md" offset= +``` + +Only after orientation should you ingest, query, or lint. This prevents: +- Creating duplicate pages for entities that already exist +- Missing cross-references to existing content +- Contradicting the schema's conventions +- Repeating work already logged + +For large wikis (100+ pages), also run a quick `search_files` for the topic +at hand before creating anything new. + +## Initializing a New Wiki + +When the user asks to create or start a wiki: + +1. Determine the wiki path (from `$WIKI_PATH` env var, or ask the user; default `~/wiki`) +2. Create the directory structure above +3. Ask the user what domain the wiki covers — be specific +4. Write `SCHEMA.md` customized to the domain (see template below) +5. Write initial `index.md` with sectioned header +6. Write initial `log.md` with creation entry +7. Confirm the wiki is ready and suggest first sources to ingest + +### SCHEMA.md Template + +Adapt to the user's domain. The schema constrains agent behavior and ensures consistency: + +```markdown +# Wiki Schema + +## Domain +[What this wiki covers — e.g., "AI/ML research", "personal health", "startup intelligence"] + +## Conventions +- File names: lowercase, hyphens, no spaces (e.g., `transformer-architecture.md`) +- Every wiki page starts with YAML frontmatter (see below) +- Use `[[wikilinks]]` to link between pages (minimum 2 outbound links per page) +- When updating a page, always bump the `updated` date +- Every new page must be added to `index.md` under the correct section +- Every action must be appended to `log.md` +- **Provenance markers:** On pages that synthesize 3+ sources, append `^[raw/articles/source-file.md]` + at the end of paragraphs whose claims come from a specific source. This lets a reader trace each + claim back without re-reading the whole raw file. Optional on single-source pages where the + `sources:` frontmatter is enough. + +## Frontmatter + ```yaml + --- + title: Page Title + created: YYYY-MM-DD + updated: YYYY-MM-DD + type: entity | concept | comparison | query | summary + tags: [from taxonomy below] + sources: [raw/articles/source-name.md] + # Optional quality signals: + confidence: high | medium | low # how well-supported the claims are + contested: true # set when the page has unresolved contradictions + contradictions: [other-page-slug] # pages this one conflicts with + --- + ``` + +`confidence` and `contested` are optional but recommended for opinion-heavy or fast-moving +topics. Lint surfaces `contested: true` and `confidence: low` pages for review so weak claims +don't silently harden into accepted wiki fact. + +### raw/ Frontmatter + +Raw sources ALSO get a small frontmatter block so re-ingests can detect drift: + +```yaml +--- +source_url: https://example.com/article # original URL, if applicable +ingested: YYYY-MM-DD +sha256: +--- +``` + +The `sha256:` lets a future re-ingest of the same URL skip processing when content is unchanged, +and flag drift when it has changed. Compute over the body only (everything after the closing +`---`), not the frontmatter itself. + +## Tag Taxonomy +[Define 10-20 top-level tags for the domain. Add new tags here BEFORE using them.] + +Example for AI/ML: +- Models: model, architecture, benchmark, training +- People/Orgs: person, company, lab, open-source +- Techniques: optimization, fine-tuning, inference, alignment, data +- Meta: comparison, timeline, controversy, prediction + +Rule: every tag on a page must appear in this taxonomy. If a new tag is needed, +add it here first, then use it. This prevents tag sprawl. + +## Page Thresholds +- **Create a page** when an entity/concept appears in 2+ sources OR is central to one source +- **Add to existing page** when a source mentions something already covered +- **DON'T create a page** for passing mentions, minor details, or things outside the domain +- **Split a page** when it exceeds ~200 lines — break into sub-topics with cross-links +- **Archive a page** when its content is fully superseded — move to `_archive/`, remove from index + +## Entity Pages +One page per notable entity. Include: +- Overview / what it is +- Key facts and dates +- Relationships to other entities ([[wikilinks]]) +- Source references + +## Concept Pages +One page per concept or topic. Include: +- Definition / explanation +- Current state of knowledge +- Open questions or debates +- Related concepts ([[wikilinks]]) + +## Comparison Pages +Side-by-side analyses. Include: +- What is being compared and why +- Dimensions of comparison (table format preferred) +- Verdict or synthesis +- Sources + +## Update Policy +When new information conflicts with existing content: +1. Check the dates — newer sources generally supersede older ones +2. If genuinely contradictory, note both positions with dates and sources +3. Mark the contradiction in frontmatter: `contradictions: [page-name]` +4. Flag for user review in the lint report +``` + +### index.md Template + +The index is sectioned by type. Each entry is one line: wikilink + summary. + +```markdown +# Wiki Index + +> Content catalog. Every wiki page listed under its type with a one-line summary. +> Read this first to find relevant pages for any query. +> Last updated: YYYY-MM-DD | Total pages: N + +## Entities + + +## Concepts + +## Comparisons + +## Queries +``` + +**Scaling rule:** When any section exceeds 50 entries, split it into sub-sections +by first letter or sub-domain. When the index exceeds 200 entries total, create +a `_meta/topic-map.md` that groups pages by theme for faster navigation. + +### log.md Template + +```markdown +# Wiki Log + +> Chronological record of all wiki actions. Append-only. +> Format: `## [YYYY-MM-DD] action | subject` +> Actions: ingest, update, query, lint, create, archive, delete +> When this file exceeds 500 entries, rotate: rename to log-YYYY.md, start fresh. + +## [YYYY-MM-DD] create | Wiki initialized +- Domain: [domain] +- Structure created with SCHEMA.md, index.md, log.md +``` + +## Core Operations + +### 1. Ingest + +When the user provides a source (URL, file, paste), integrate it into the wiki: + +① **Capture the raw source:** + - URL → use `web_extract` to get markdown, save to `raw/articles/` + - PDF → use `web_extract` (handles PDFs), save to `raw/papers/` + - Pasted text → save to appropriate `raw/` subdirectory + - Name the file descriptively: `raw/articles/karpathy-llm-wiki-2026.md` + - **Add raw frontmatter** (`source_url`, `ingested`, `sha256` of the body). + On re-ingest of the same URL: recompute the sha256, compare to the stored value — + skip if identical, flag drift and update if different. This is cheap enough to + do on every re-ingest and catches silent source changes. + +② **Discuss takeaways** with the user — what's interesting, what matters for + the domain. (Skip this in automated/cron contexts — proceed directly.) + +③ **Check what already exists** — search index.md and use `search_files` to find + existing pages for mentioned entities/concepts. This is the difference between + a growing wiki and a pile of duplicates. + +④ **Write or update wiki pages:** + - **New entities/concepts:** Create pages only if they meet the Page Thresholds + in SCHEMA.md (2+ source mentions, or central to one source) + - **Existing pages:** Add new information, update facts, bump `updated` date. + When new info contradicts existing content, follow the Update Policy. + - **Cross-reference:** Every new or updated page must link to at least 2 other + pages via `[[wikilinks]]`. Check that existing pages link back. + - **Tags:** Only use tags from the taxonomy in SCHEMA.md + - **Provenance:** On pages synthesizing 3+ sources, append `^[raw/articles/source.md]` + markers to paragraphs whose claims trace to a specific source. + - **Confidence:** For opinion-heavy, fast-moving, or single-source claims, set + `confidence: medium` or `low` in frontmatter. Don't mark `high` unless the + claim is well-supported across multiple sources. + +⑤ **Update navigation:** + - Add new pages to `index.md` under the correct section, alphabetically + - Update the "Total pages" count and "Last updated" date in index header + - Append to `log.md`: `## [YYYY-MM-DD] ingest | Source Title` + - List every file created or updated in the log entry + +⑥ **Report what changed** — list every file created or updated to the user. + +A single source can trigger updates across 5-15 wiki pages. This is normal +and desired — it's the compounding effect. + +### 2. Query + +When the user asks a question about the wiki's domain: + +① **Read `index.md`** to identify relevant pages. +② **For wikis with 100+ pages**, also `search_files` across all `.md` files + for key terms — the index alone may miss relevant content. +③ **Read the relevant pages** using `read_file`. +④ **Synthesize an answer** from the compiled knowledge. Cite the wiki pages + you drew from: "Based on [[page-a]] and [[page-b]]..." +⑤ **File valuable answers back** — if the answer is a substantial comparison, + deep dive, or novel synthesis, create a page in `queries/` or `comparisons/`. + Don't file trivial lookups — only answers that would be painful to re-derive. +⑥ **Update log.md** with the query and whether it was filed. + +### 3. Lint + +When the user asks to lint, health-check, or audit the wiki: + +① **Orphan pages:** Find pages with no inbound `[[wikilinks]]` from other pages. +```python +# Use execute_code for this — programmatic scan across all wiki pages +import os, re +from collections import defaultdict +wiki = "" +# Scan all .md files in entities/, concepts/, comparisons/, queries/ +# Extract all [[wikilinks]] — build inbound link map +# Pages with zero inbound links are orphans +``` + +② **Broken wikilinks:** Find `[[links]]` that point to pages that don't exist. + +③ **Index completeness:** Every wiki page should appear in `index.md`. Compare + the filesystem against index entries. + +④ **Frontmatter validation:** Every wiki page must have all required fields + (title, created, updated, type, tags, sources). Tags must be in the taxonomy. + +⑤ **Stale content:** Pages whose `updated` date is >90 days older than the most + recent source that mentions the same entities. + +⑥ **Contradictions:** Pages on the same topic with conflicting claims. Look for + pages that share tags/entities but state different facts. Surface all pages + with `contested: true` or `contradictions:` frontmatter for user review. + +⑦ **Quality signals:** List pages with `confidence: low` and any page that cites + only a single source but has no confidence field set — these are candidates + for either finding corroboration or demoting to `confidence: medium`. + +⑧ **Source drift:** For each file in `raw/` with a `sha256:` frontmatter, recompute + the hash and flag mismatches. Mismatches indicate the raw file was edited + (shouldn't happen — raw/ is immutable) or ingested from a URL that has since + changed. Not a hard error, but worth reporting. + +⑨ **Page size:** Flag pages over 200 lines — candidates for splitting. + +⑩ **Tag audit:** List all tags in use, flag any not in the SCHEMA.md taxonomy. + +⑪ **Log rotation:** If log.md exceeds 500 entries, rotate it. + +⑫ **Report findings** with specific file paths and suggested actions, grouped by + severity (broken links > orphans > source drift > contested pages > stale content > style issues). + +⑬ **Append to log.md:** `## [YYYY-MM-DD] lint | N issues found` + +## Working with the Wiki + +### Searching + +```bash +# Find pages by content +search_files "transformer" path="$WIKI" file_glob="*.md" + +# Find pages by filename +search_files "*.md" target="files" path="$WIKI" + +# Find pages by tag +search_files "tags:.*alignment" path="$WIKI" file_glob="*.md" + +# Recent activity +read_file "$WIKI/log.md" offset= +``` + +### Bulk Ingest + +When ingesting multiple sources at once, batch the updates: +1. Read all sources first +2. Identify all entities and concepts across all sources +3. Check existing pages for all of them (one search pass, not N) +4. Create/update pages in one pass (avoids redundant updates) +5. Update index.md once at the end +6. Write a single log entry covering the batch + +### Archiving + +When content is fully superseded or the domain scope changes: +1. Create `_archive/` directory if it doesn't exist +2. Move the page to `_archive/` with its original path (e.g., `_archive/entities/old-page.md`) +3. Remove from `index.md` +4. Update any pages that linked to it — replace wikilink with plain text + "(archived)" +5. Log the archive action + +### Obsidian Integration + +The wiki directory works as an Obsidian vault out of the box: +- `[[wikilinks]]` render as clickable links +- Graph View visualizes the knowledge network +- YAML frontmatter powers Dataview queries +- The `raw/assets/` folder holds images referenced via `![[image.png]]` + +For best results: +- Set Obsidian's attachment folder to `raw/assets/` +- Enable "Wikilinks" in Obsidian settings (usually on by default) +- Install Dataview plugin for queries like `TABLE tags FROM "entities" WHERE contains(tags, "company")` + +If using the Obsidian skill alongside this one, set `OBSIDIAN_VAULT_PATH` to the +same directory as the wiki path. + +### Obsidian Headless (servers and headless machines) + +On machines without a display, use `obsidian-headless` instead of the desktop app. +It syncs vaults via Obsidian Sync without a GUI — perfect for agents running on +servers that write to the wiki while Obsidian desktop reads it on another device. + +**Setup:** +```bash +# Requires Node.js 22+ +npm install -g obsidian-headless + +# Login (requires Obsidian account with Sync subscription) +ob login --email --password '' + +# Create a remote vault for the wiki +ob sync-create-remote --name "LLM Wiki" + +# Connect the wiki directory to the vault +cd ~/wiki +ob sync-setup --vault "" + +# Initial sync +ob sync + +# Continuous sync (foreground — use systemd for background) +ob sync --continuous +``` + +**Continuous background sync via systemd:** +```ini +# ~/.config/systemd/user/obsidian-wiki-sync.service +[Unit] +Description=Obsidian LLM Wiki Sync +After=network-online.target +Wants=network-online.target + +[Service] +ExecStart=/path/to/ob sync --continuous +WorkingDirectory=%h/wiki +Restart=on-failure +RestartSec=10 + +[Install] +WantedBy=default.target +``` + +```bash +systemctl --user daemon-reload +systemctl --user enable --now obsidian-wiki-sync +# Enable linger so sync survives logout: +sudo loginctl enable-linger $USER +``` + +This lets the agent write to `~/wiki` on a server while you browse the same +vault in Obsidian on your laptop/phone — changes appear within seconds. + +## Pitfalls + +- **Never modify files in `raw/`** — sources are immutable. Corrections go in wiki pages. +- **Always orient first** — read SCHEMA + index + recent log before any operation in a new session. + Skipping this causes duplicates and missed cross-references. +- **Always update index.md and log.md** — skipping this makes the wiki degrade. These are the + navigational backbone. +- **Don't create pages for passing mentions** — follow the Page Thresholds in SCHEMA.md. A name + appearing once in a footnote doesn't warrant an entity page. +- **Don't create pages without cross-references** — isolated pages are invisible. Every page must + link to at least 2 other pages. +- **Frontmatter is required** — it enables search, filtering, and staleness detection. +- **Tags must come from the taxonomy** — freeform tags decay into noise. Add new tags to SCHEMA.md + first, then use them. +- **Keep pages scannable** — a wiki page should be readable in 30 seconds. Split pages over + 200 lines. Move detailed analysis to dedicated deep-dive pages. +- **Ask before mass-updating** — if an ingest would touch 10+ existing pages, confirm + the scope with the user first. +- **Rotate the log** — when log.md exceeds 500 entries, rename it `log-YYYY.md` and start fresh. + The agent should check log size during lint. +- **Handle contradictions explicitly** — don't silently overwrite. Note both claims with dates, + mark in frontmatter, flag for user review. + +## Related Tools + +[llm-wiki-compiler](https://github.com/atomicmemory/llm-wiki-compiler) is a Node.js CLI that +compiles sources into a concept wiki with the same Karpathy inspiration.

Copy the app's Client ID and Client Secret +4. Register the app locally (user runs this): + ```bash + xurl auth apps add my-app --client-id YOUR_CLIENT_ID --client-secret YOUR_CLIENT_SECRET + ``` +5. Authenticate (specify `--app` to bind the token to your app): + ```bash + xurl auth oauth2 --app my-app + ``` + (This opens a browser for the OAuth 2.0 PKCE flow.) + + If X returns a `UsernameNotFound` error or 403 on the post-OAuth `/2/users/me` lookup, pass your handle explicitly (xurl v1.1.0+): + ```bash + xurl auth oauth2 --app my-app YOUR_USERNAME + ``` + This binds the token to your handle and skips the broken `/2/users/me` call. +6. Set the app as default so all commands use it: + ```bash + xurl auth default my-app + ``` +7. Verify: + ```bash + xurl auth status + xurl whoami + ``` + +After this, the agent can use any command below without further setup. OAuth 2.0 tokens auto-refresh. + +> **Common pitfall:** If you omit `--app my-app` from `xurl auth oauth2`, the OAuth token is saved to the built-in `default` app profile — which has no client-id or client-secret. Commands will fail with auth errors even though the OAuth flow appeared to succeed. If you hit this, re-run `xurl auth oauth2 --app my-app` and `xurl auth default my-app`. + +> **Docker HOME pitfall:** In the official Hermes Docker layout, `/opt/data` is `HERMES_HOME`, but Hermes tool subprocesses use `/opt/data/home` as `HOME`. That means `~/.xurl` resolves to `/opt/data/home/.xurl` for Hermes-run `xurl` commands, not `/opt/data/.xurl`. Run the user setup with the same HOME: +> ```bash +> HOME=/opt/data/home xurl auth apps add my-app --client-id YOUR_CLIENT_ID --client-secret YOUR_CLIENT_SECRET +> HOME=/opt/data/home xurl auth oauth2 --app my-app YOUR_USERNAME +> HOME=/opt/data/home xurl auth default my-app YOUR_USERNAME +> HOME=/opt/data/home xurl auth status +> ``` +> If `HOME=/opt/data xurl auth status` succeeds but `HOME=/opt/data/home xurl auth status` shows no apps or tokens, Hermes tool calls will not see the credentials. + +--- + +## Quick Reference + +| Action | Command | +| --- | --- | +| Post | `xurl post "Hello world!"` | +| Reply | `xurl reply POST_ID "Nice post!"` | +| Quote | `xurl quote POST_ID "My take"` | +| Delete a post | `xurl delete POST_ID` | +| Read a post | `xurl read POST_ID` | +| Search posts | `xurl search "QUERY" -n 10` | +| Who am I | `xurl whoami` | +| Look up a user | `xurl user @handle` | +| Home timeline | `xurl timeline -n 20` | +| Mentions | `xurl mentions -n 10` | +| Like / Unlike | `xurl like POST_ID` / `xurl unlike POST_ID` | +| Repost / Undo | `xurl repost POST_ID` / `xurl unrepost POST_ID` | +| Bookmark / Remove | `xurl bookmark POST_ID` / `xurl unbookmark POST_ID` | +| List bookmarks / likes | `xurl bookmarks -n 10` / `xurl likes -n 10` | +| Follow / Unfollow | `xurl follow @handle` / `xurl unfollow @handle` | +| Following / Followers | `xurl following -n 20` / `xurl followers -n 20` | +| Block / Unblock | `xurl block @handle` / `xurl unblock @handle` | +| Mute / Unmute | `xurl mute @handle` / `xurl unmute @handle` | +| Send DM | `xurl dm @handle "message"` | +| List DMs | `xurl dms -n 10` | +| Upload media | `xurl media upload path/to/file.mp4` | +| Media status | `xurl media status MEDIA_ID` | +| List apps | `xurl auth apps list` | +| Remove app | `xurl auth apps remove NAME` | +| Set default app | `xurl auth default APP_NAME [USERNAME]` | +| Per-request app | `xurl --app NAME /2/users/me` | +| Auth status | `xurl auth status` | + +Notes: +- `POST_ID` accepts full URLs too (e.g. `https://x.com/user/status/1234567890`) — xurl extracts the ID. +- Usernames work with or without a leading `@`. + +--- + +## Command Details + +### Posting + +```bash +xurl post "Hello world!" +xurl post "Check this out" --media-id MEDIA_ID +xurl post "Thread pics" --media-id 111 --media-id 222 + +xurl reply 1234567890 "Great point!" +xurl reply https://x.com/user/status/1234567890 "Agreed!" +xurl reply 1234567890 "Look at this" --media-id MEDIA_ID + +xurl quote 1234567890 "Adding my thoughts" +xurl delete 1234567890 +``` + +### Reading & Search + +`xurl search` queries the X index as your authenticated account and returns raw post objects — IDs, authors, full text — so results can be immediately engaged with (reply, like, repost, quote).

An auth failure there surfaces as an auth error. + +--- + +## Agent Workflow + +1. Verify prerequisites: `xurl --help` and `xurl auth status`. +2. Before using `xurl search`, check intent. Reach for it when the task needs actual post objects, authenticated account context, or leads into an X write action — it is the right surface when the user wants posts they can engage with, not just a summary of a topic. +3. **Check default app has credentials.** Parse the `auth status` output. The default app is marked with `▸`. If the default app shows `oauth2: (none)` but another app has a valid oauth2 user, tell the user to run `xurl auth default ` to fix it. This is the most common setup mistake — the user added an app with a custom name but never set it as default, so xurl keeps trying the empty `default` profile. +4. If auth is missing entirely, stop and direct the user to the "One-Time User Setup" section — do NOT attempt to register apps or pass secrets yourself. +5. Start with a cheap read (`xurl whoami`, `xurl user @handle`, `xurl search ... -n 3`) to confirm reachability. +6. Confirm the target post/user and the user's intent before any write action (post, reply, like, repost, DM, follow, block, delete). +7. Only the `xurl` command output (or the raw X API response) proves that a state-changing X action happened. Never report a write as done based on any other source — search results, summaries, or prior context. +8. Use JSON output directly — every response is already structured. +9. Never paste `~/.xurl` contents back into the conversation. + +--- + +## Troubleshooting + +| Symptom | Cause | Fix | +| --- | --- | --- | +| Auth errors after successful OAuth flow | Token saved to `default` app (no client-id/secret) instead of your named app | `xurl auth oauth2 --app my-app` then `xurl auth default my-app` | +| `unauthorized_client` during OAuth | App type set to "Native App" in X dashboard | Change to "Web app, automated app or bot" in User Authentication Settings | +| `UsernameNotFound` or 403 on `/2/users/me` right after OAuth | X not returning username reliably from `/2/users/me` | Re-run `xurl auth oauth2 --app my-app YOUR_USERNAME` (xurl v1.1.0+) to pass the handle explicitly | +| 401 on every request | Token expired or wrong default app | Check `xurl auth status` — verify `▸` points to an app with oauth2 tokens | +| `client-forbidden` / `client-not-enrolled` | X platform enrollment issue | Dashboard → Apps → Manage → Move to "Pay-per-use" package → Production environment | +| `CreditsDepleted` | $0 balance on X API | Buy credits (min $5) in Developer Console → Billing | +| `media processing failed` on image upload | Default category is `amplify_video` | Add `--category tweet_image --media-type image/png` | +| Two "Client Secret" values in X dashboard | UI bug — first is actually Client ID | Confirm on the "Keys and tokens" page; ID ends in `MTpjaQ` | + +--- + +## Notes + +- **Rate limits:** X enforces per-endpoint rate limits. A 429 means wait and retry. Write endpoints (post, reply, like, repost) have tighter limits than reads. +- **Scopes:** OAuth 2.0 tokens use broad scopes. A 403 on a specific action usually means the token is missing a scope — have the user re-run `xurl auth oauth2`. +- **Token refresh:** OAuth 2.0 tokens auto-refresh. Nothing to do. +- **Multiple apps:** Each app has isolated credentials/tokens. Switch with `xurl auth default` or `--app`. +- **Multiple accounts per app:** Select with `-u / --username`, or set a default with `xurl auth default APP USER`. +- **Token storage:** `~/.xurl` is YAML. In Docker, use the Hermes subprocess HOME (`/opt/data/home` in the official image) so tokens land under `/opt/data/home/.xurl`. Never read or send this file to LLM context. +- **Cost:** X API access is typically paid for meaningful usage.

The body is a snapshot from filing time; the newest comments carry the live state: partial fixes already merged, new root-cause analyses, maintainer decisions, or questions directed at you that change the task.

Done when you know every open PR and recent commit touching this issue, or that none exist. + +### 3. Validate the premise against current code — and against design intent + +Reproduce the bug or demonstrate the missing behavior on the current default branch with a failing test or fixture, using `search_files` and `read_file` to trace the reported path. Then check the second question: is the "bug" actually deliberate design? Run `git log -p -S ""` on the code the issue wants changed and read the original commit's intent — a missing link or restriction is often the feature. Challenge stale or flawed issue prose instead of implementing it blindly. Done when the root cause or feature gap is demonstrated in current code AND the change doesn't fight an intentional design. + +### 4.

Implement the smallest complete change — and fix the class + +Work on an isolated branch or worktree, loading `systematic-debugging` or `test-driven-development` when the bug class calls for them. Add regression tests first, then implement. When the fix is in hand, `search_files` for the same bug shape at sibling call sites and fix the whole class in this PR — an incomplete fix that leaves known siblings broken is worse than none. Every changed line must trace to the issue; no drive-by cleanup.

Run repository quality gates, then open the PR immediately + +Run the formatter, lint, typecheck, and the repo's canonical test entrypoint on affected areas; use `requesting-code-review` on the diff. Then push and open the PR right away — the PR is what dispatches CI, and CI latency is the long pole; do not sit on finished work. Load `github-pr-workflow` for PR mechanics: conventional branch/commit, body linking the issue with problem, approach, tests, risk, and exclusions.

"Would be useful to anyone who ever needs this" is an optional-tier argument, not a bundled one. + +Pick the category by what the tool IS, not what it feels like (an AI-agent CLI goes in `autonomous-ai-agents/` even if it "feels productivity").

Do NOT name shell utilities the agent already has wrapped (`grep` → `search_files`, `cat` → `read_file`, `sed`/`awk` → `patch`, `find`/`ls` → `search_files target='files'`). A CLI-wrapper skill should frame invocations as `terminal(command="{tool} ...", timeout=...)` — bare shell prose ("run `foo --version`") is a review-blocking non-conformance. If the skill depends on an MCP server, name it and document setup in Prerequisites. + +### Never use machine-local paths + +Write repo-relative paths (`skills/...`, `tools/skill_manager_tool.py`). A `/home//...` path baked into a committed skill breaks for every other user and is an instant review flag. + +## Writing Quality Principles + +A skill exists to make the agent's process more predictable — the agent reliably follows the same useful discipline. + +1. **Optimize for process predictability.** If a line does not change behavior, cut it. +2. **Choose the right context load.** The description is paid for every turn; details go in the body or linked references. +3. **End steps with completion criteria.** Checkable and, when it matters, exhaustive: "every modified file accounted for" beats "summarize changes." +4. **Co-locate rules with the concept they govern.** +5. **Use strong leading words** ("tight loop," "root cause," "regression test") over long repeated explanations. +6. **Prune duplication and no-ops.** "Be careful" and "use best practices" don't change model behavior — replace with a checkable criterion or delete. + +## Tests and Docs (required for repo skills) + +1. **Tests** live at `tests/skills/test__skill.py` — stdlib + pytest + `unittest.mock` only, no live network. Run via `scripts/run_tests.sh tests/skills/test__skill.py -q`. (The generic `tests/tools/test_skill_manager_tool.py` passing proves nothing about YOUR skill.) +2. **Docs regen:** run `python website/scripts/generate-skill-docs.py`, then apply scope discipline — the generator rewrites EVERY auto-gen page. `git checkout --` everything that isn't yours; the final diff must show only your SKILL.md, your one per-skill docs page, a one-line catalog row, and a one-line `website/sidebars.ts` insertion (verify with `search_files(pattern='', path='website/sidebars.ts')` — exactly one hit, or the page is an orphan). +3. **`.env.example`** (only if the skill needs new env vars): one clearly delimited commented block; touch nothing else in the file. + +## Workflow + +1. **Survey peers** in the target category with `search_files(target='files')` and read 2-3 peer SKILL.md files to match tone and structure. Prefer extending an existing skill over creating a narrow sibling. +2. **Decide tier and category** (see above). When in doubt, optional — and ask before pushing rather than defaulting. +3. **Draft** with `write_file` to `skills///SKILL.md` (or `optional-skills/...`). +4. **Validate locally**: + ```python + import re, pathlib + from ruamel.yaml import YAML + content = pathlib.Path("skills///SKILL.md").read_text() + assert content.startswith("---") + m = re.search(r'\n---\s*\n', content[3:]) + fm = YAML(typ="safe").load(content[3:m.start()+3]) + assert "name" in fm and "description" in fm + assert len(fm["description"]) <= 60, f"description {len(fm['description'])} chars — hardline is 60" + assert fm["description"].endswith(".") + assert "platforms" in fm + assert len(content) <= 100_000 + ``` + Also verify every `related_skills` entry exists in-repo. +5. **Add tests + regen docs** (previous section). +6. **Git add + commit** on the active branch; open a PR. +7. **Note:** the CURRENT session's skill loader is cached — `skill_view` / `skills_list` will not see the new skill until a new session. This is expected, not a bug. + +## Editing Existing In-Repo Skills + +- **Small fix:** `skill_manage(action='patch', ...)` works on in-repo skills, as does `patch`. +- **Major rewrite:** `write_file` the whole SKILL.md. +- **Supporting files:** `write_file` to `references/`, `templates/`, or `scripts/` under the skill dir. +- **Always commit** — in-repo skills are source, not runtime state. Re-run the docs generator when frontmatter changed. + +## Common Pitfalls + +1. **Using `skill_manage(action='create')` for an in-repo skill.** It writes to `~/.hermes/skills/`, not the repo tree. Use `write_file`. +2. **Trusting the validator's limits as the standard.** The validator allows 1024-char descriptions; review rejects anything over 60. The validator doesn't check `platforms:`, author format, tests, or docs — review does. +3. **`author: Hermes Agent` on a contributed skill.** Credit the human first. +4. **Leading whitespace before `---`.** Validation fails on any leading blank line or BOM. +5. **Description too generic or trigger buried past char 57.** +6. **`related_skills` pointing at skills that don't exist in-repo** (user-local, planned, or in a sibling PR). +7. **Duplicating a peer.** Survey the category first; extend rather than sibling. +8. **Skipping the docs generator or pushing its unrelated drift.** Both directions are wrong: no regen = orphan skill with no docs page; blind regen = a ballooned diff full of other skills' drift. +9. **Expecting the current session to see the new skill.** The loader is initialized at session start. +10. **Letting skills accumulate sediment.** When adding a rule, remove the old wording it replaces. + +## Verification Checklist + +- [ ] Tier decided deliberately (bundled bar: 5+ sessions/month; else `optional-skills/`) +- [ ] File at `skills///SKILL.md` or `optional-skills///SKILL.md` +- [ ] Frontmatter starts at byte 0 with `---`, closes with `\n---\n` +- [ ] `name`, `description`, `version`, `author`, `license`, `platforms`, `metadata.hermes.{tags, related_skills}` all present +- [ ] Description ≤ 60 chars, one sentence, ends with a period, no marketing words +- [ ] `author` credits the human contributor first +- [ ] `platforms:` audited against actual prose/scripts, not copied from a sibling +- [ ] Every `related_skills` entry resolves in-repo +- [ ] Body follows the modern section order; commands framed through Hermes tools +- [ ] No machine-local paths anywhere in the file +- [ ] Each ordered step has a checkable completion criterion +- [ ] Tests at `tests/skills/test__skill.py` pass under `scripts/run_tests.sh` +- [ ] Docs regenerated with scope discipline; sidebar has exactly one entry for the slug +- [ ] `git add` + commit on the intended branch; PR opened diff --git a/skills/software-development/inspecting-hermes-desktop-dom/SKILL.md b/skills/software-development/inspecting-hermes-desktop-dom/SKILL.md new file mode 100644 index 0000000..e963370 --- /dev/null +++ b/skills/software-development/inspecting-hermes-desktop-dom/SKILL.md @@ -0,0 +1,159 @@ +--- +name: inspecting-hermes-desktop-dom +description: "Read the live Hermes desktop DOM/CSS over CDP." +version: 1.0.0 +author: Hermes Agent +license: MIT +platforms: [linux, macos, windows] +metadata: + hermes: + tags: [desktop, electron, cdp, dom, ui-verification, self-inspection] + related_skills: [node-inspect-debugger, systematic-debugging, dogfood] +--- + +# Inspecting the live Hermes desktop DOM + +## Overview + +When you are developing `apps/desktop` and the user is running that same app +(`hgui` / `npm run dev`), you can read the **live rendered DOM** of the window +they are looking at — computed styles, geometry, which CSS rule actually won, +console output — instead of inferring it from `.tsx` and being wrong. + +Dev-server runs open a Chrome DevTools Protocol port on `127.0.0.1:9222` +automatically.

Attach +node inspect ws://127.0.0.1:9229/ +``` + +Interacting with the TUI (typing in its window) continues to advance execution; your debugger can pause it on a breakpoint at any `sb(...)`. + +### Debugging `_SlashWorker` / PTY child processes + +Those are Python, not Node — use the `python-debugpy` skill for them. Only Node portions (Ink UI, tui_gateway client, tsx-run tests under `ui-tui/`) use this skill. + +## Running Vitest Tests Under the Debugger + +```bash +cd /ui-tui +# Run a single test file paused on entry +node --inspect-brk ./node_modules/vitest/vitest.mjs run --no-file-parallelism src/app/foo.test.tsx +``` + +In another terminal: `node inspect -p `, then `sb('src/app/foo.tsx', 42)`, `cont`. + +Use `--no-file-parallelism` (vitest) or `--runInBand` (jest) so only one worker exists — debugging a pool is painful. + +## Heap Snapshots & CPU Profiles (Non-interactive) + +From the CDP driver above, swap Debugger for `HeapProfiler` / `Profiler`: + +```javascript +// CPU profile for 5 seconds +await client.Profiler.enable(); +await client.Profiler.start(); +await new Promise(r => setTimeout(r, 5000)); +const { profile } = await client.Profiler.stop(); +require('fs').writeFileSync('~/.hermes/cache/scratch/cpu.cpuprofile', JSON.stringify(profile)); +// Open ~/.hermes/cache/scratch/cpu.cpuprofile in Chrome DevTools → Performance tab +``` + +```javascript +// Heap snapshot +await client.HeapProfiler.enable(); +const chunks = []; +client.HeapProfiler.addHeapSnapshotChunk(({ chunk }) => chunks.push(chunk)); +await client.HeapProfiler.takeHeapSnapshot({ reportProgress: false }); +require('fs').writeFileSync('~/.hermes/cache/scratch/heap.heapsnapshot', chunks.join('')); +``` + +## Common Pitfalls + +1. **Wrong line numbers in TS source.** Breakpoints hit the emitted JS, not the `.ts`. Either (a) break in the built `dist/*.js`, or (b) enable sourcemaps (`node --enable-source-maps`) and use `sb('src/app.tsx', N)` — but only with CDP clients that follow sourcemaps. `node inspect` CLI does not. + +2. **`--inspect` vs `--inspect-brk`.** `--inspect` starts the inspector but doesn't pause; your script races past your first breakpoint if you attach too late. Use `--inspect-brk` when you need to set breakpoints before any code runs. + +3. **Port collisions.** Default is `9229`. If multiple Node processes are inspecting, pass `--inspect=0` (random port) and read the actual URL from `/json/list`: + ```bash + curl -s http://127.0.0.1:9229/json/list # lists all inspectable targets on the host + ``` + +4. **Child processes.** `--inspect` on a parent does NOT inspect its children. Use `NODE_OPTIONS='--inspect-brk' node parent.js` to propagate to every child; be aware they all need unique ports (Node auto-increments when `NODE_OPTIONS='--inspect'` is inherited). + +5. **Background kills.** If you `Ctrl+C` out of `node inspect` while the target is paused, the target stays paused. Either `cont` first, or `kill` the target explicitly. + +6. **Running `node inspect` through an agent terminal.** It's a PTY-friendly REPL.

Follow the +[PM developer workflow](https://hermes-agent.nousresearch.com/docs/reference/package-management#developer-workflow) +and activate that checkout — PowerShell: `. .\activate.ps1`. The declared `dev` +extra includes debugpy, which PM activation does not sync (`all` excludes it). +Through `terminal`, build a fresh, caller-owned debug/test environment with the +prepared checkout's Python: + +```bash +source ./activate +python -m pm.build_env --source . --out .venv --group dev --group test +.venv/bin/python -c "import debugpy; print(debugpy.__file__)" +``` + +The output must not already exist. Stop its processes and intentionally remove +only that disposable environment before rebuilding. Keep the same isolated +`HERMES_HOME` for the debug target. `.venv/bin/python` is this explicitly built +debug environment, not a guessed application venv, and the patterns below run +through it. Do not add debugpy to a running production environment; reproduce +there only with an already-prepared debug target or arrange a restart in the +development environment. + +### Pattern A: Source-edit — process waits for debugger at launch + +Add near the top of the entry point (or inside the function you want to debug): + +```python +import debugpy +debugpy.listen(("127.0.0.1", 5678)) +print("debugpy listening on 5678, waiting for client...", flush=True) +debugpy.wait_for_client() +debugpy.breakpoint() # optional: pause immediately once attached +``` + +Start the process; it blocks on `wait_for_client()`. + +### Pattern B: No source edit — launch with `-m debugpy` + +```bash +.venv/bin/python -m debugpy --listen 127.0.0.1:5678 --wait-for-client your_script.py arg1 +``` + +Equivalent for module entry: + +```bash +.venv/bin/python -m debugpy --listen 127.0.0.1:5678 --wait-for-client -m your.module +``` + +### Pattern C: Attach to an already-running process + +Needs the PID and debugpy preinstalled in the target's environment: + +```bash +.venv/bin/python -m debugpy --listen 127.0.0.1:5678 --pid +# debugpy injects itself into the process. Then attach a client as below. +``` + +Some kernels/security configs block the ptrace-based injection (`/proc/sys/kernel/yama/ptrace_scope`). Fix with: +```bash +echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope +``` + +### Connecting a client from the terminal + +The easiest terminal-side DAP client is VS Code CLI or a small script. From inside Hermes you have two practical options: + +**Option 1: `debugpy`'s own CLI REPL** — not an official feature, but a tiny DAP client script: + +```python +# ~/.hermes/cache/scratch/dap_client.py +import socket, json, itertools, time, sys + +HOST, PORT = "127.0.0.1", 5678 +s = socket.create_connection((HOST, PORT)) +seq = itertools.count(1) + +def send(msg): + msg["seq"] = next(seq) + body = json.dumps(msg).encode() + s.sendall(f"Content-Length: {len(body)}\r\n\r\n".encode() + body) + +def recv(): + header = b"" + while b"\r\n\r\n" not in header: + header += s.recv(1) + length = int(header.decode().split("Content-Length:")[1].split("\r\n")[0].strip()) + body = b"" + while len(body) < length: + body += s.recv(length - len(body)) + return json.loads(body) + +send({"type": "request", "command": "initialize", "arguments": {"adapterID": "python"}}) +print(recv()) +send({"type": "request", "command": "attach", "arguments": {}}) +print(recv()) +send({"type": "request", "command": "setBreakpoints", + "arguments": {"source": {"path": sys.argv[1]}, + "breakpoints": [{"line": int(sys.argv[2])}]}}) +print(recv()) +send({"type": "request", "command": "configurationDone"}) +# ... loop reading events and sending continue/stepIn/etc. +``` + +This is fine for one-off automation but painful as an interactive UX. + +**Option 2: Attach from VS Code / Cursor / Zed** — if the user has one open, they can add a `launch.json`: + +```json +{ + "name": "Attach to Hermes", + "type": "debugpy", + "request": "attach", + "connect": { "host": "127.0.0.1", "port": 5678 }, + "justMyCode": false, + "pathMappings": [ + { "localRoot": "${workspaceFolder}", "remoteRoot": "" } + ] +} +``` + +**Option 3: Ditch DAP, use `remote-pdb`** — usually what you actually want from a terminal agent: + +For an independently owned Python project, declare `remote-pdb` in that +project's development dependencies and prepare its debug environment through +the project's package manager. This is not a Hermes SDK install recipe. For +Hermes, prefer the declared debugpy dependency; the remote-pdb examples below +require a separately declared, freshly built debug environment, never an +in-place pip install into the selected application generation. + +In your code: +```python +from remote_pdb import set_trace +set_trace(host="127.0.0.1", port=4444) # blocks until connection +``` + +Then from the terminal: +```bash +nc 127.0.0.1 4444 +# You get a (Pdb) prompt exactly as if debugging locally. +``` + +`remote-pdb` is the cleanest agent-friendly choice when `debugpy`'s DAP protocol is overkill. Use `debugpy` only when you actually need IDE integration. + +## Debugging Hermes-specific Processes + +### Tests +See Recipe 3. The wrapper captures subprocess output, so run pytest directly for interactive pdb. + +### `run_agent.py` / CLI — one-shot +In the prepared debug checkout, add `breakpoint()` near the suspect line, then +run `python hermes`. Control returns to your terminal at the pause point. + +### `tui_gateway` subprocess (spawned by `hermes --tui`) +The gateway runs as a child of the Node TUI. Options: + +**A. Source-edit the gateway:** +```python +# tui_gateway/server.py near the top of serve() +import debugpy +debugpy.listen(("127.0.0.1", 5678)) +debugpy.wait_for_client() +``` +Start `python hermes --tui` from the prepared debug checkout. The TUI will appear frozen (its backend is waiting). Attach a client; execution resumes when you `continue`. Check the child's interpreter and imports before assuming it inherited the debug environment. + +**B. Use `remote-pdb` at a specific handler:** +```python +from remote_pdb import set_trace +set_trace(host="127.0.0.1", port=4444) # in the RPC handler you want to trap +``` +Trigger the matching slash command from the TUI, then `nc 127.0.0.1 4444` in another terminal. + +### `_SlashWorker` subprocess +Same pattern — `remote-pdb` with `set_trace()` inside the worker's `exec` path. The worker is persistent across slash commands, so the first trigger blocks until you connect; subsequent slash commands pass through normally unless you re-arm. + +### Gateway (`gateway/run.py`) +Long-lived. Use `remote-pdb` at a handler, or `debugpy` with `--wait-for-client` if you're restarting the gateway anyway. + +## Common Pitfalls + +1. **pdb under a parallel/output-capturing runner silently does nothing.** You won't see the prompt, the test just hangs (true of pytest-xdist and of `scripts/run_tests.sh`'s captured per-file subprocesses). Run pytest directly on a single file for interactive debugging. + +2. **`breakpoint()` in CI / non-TTY contexts hangs the process.** Safe locally; never commit it. Add a pre-commit grep as a safety net. + +3. **`PYTHONBREAKPOINT=0`** disables all `breakpoint()` calls. Check the env if your breakpoint isn't hitting: + ```bash + echo $PYTHONBREAKPOINT + ``` + +4. **`debugpy.listen` blocks only if you also call `wait_for_client()`.** Without it, execution continues and your first breakpoint may fire before the client is attached. + +5. **Attach to PID fails on hardened kernels.** `ptrace_scope=1` (Ubuntu default) allows only same-user ptrace of child processes. Workaround: `echo 0 > /proc/sys/kernel/yama/ptrace_scope` (needs root) or launch under `debugpy` from the start. + +6. **Threads.** `pdb` only debugs the current thread. For multithreaded code, use `debugpy` (thread-aware DAP) or set `threading.settrace()` per thread. + +7. **asyncio.** `pdb` works in coroutines but `await` inside pdb requires Python 3.13+ or `await` from `interact` mode on older versions. For 3.11/3.12, use `asyncio.run_coroutine_threadsafe` tricks or `!stmt`-based awaits via `asyncio.ensure_future`. + +8. **`scripts/run_tests.sh` strips credentials and sets `HOME=`.** If your bug depends on user config or real API keys, it won't reproduce under the wrapper. Debug with raw `pytest` first to repro, then re-confirm under the wrapper. + +9. **Forking / multiprocessing.** pdb does not follow forks. Each child needs its own `breakpoint()` or `set_trace()`. For Hermes subagents, debug one process at a time. + +## Verification Checklist + +- [ ] In the independently built debug environment, confirm: `.venv/bin/python -c "import debugpy; print(debugpy.__version__); print(debugpy.__file__)"` +- [ ] For remote debug, confirm the port is actually listening: `ss -tlnp | grep 5678` +- [ ] First breakpoint actually hits (if it doesn't, you likely have `PYTHONBREAKPOINT=0`, you're under a parallel/capturing runner, or execution finished before attach) +- [ ] `where` / `w` shows the expected call stack +- [ ] Post-debug cleanup: no stray `breakpoint()` / `set_trace()` in committed code + ```bash + rg -n 'breakpoint\(\)|set_trace\(|debugpy\.listen' --type py + ``` + +## One-Shot Recipes + +**"Why is this dict missing a key?"** +```python +# add above the KeyError site +breakpoint() +# then in pdb: +(Pdb) pp d +(Pdb) pp list(d.keys()) +(Pdb) w # how did we get here +``` + +**"This test passes in isolation but fails in the suite."** +```bash +scripts/run_tests.sh tests/the_test.py # confirm it fails under the isolated runner first +# For interactive debugging, or if it only fails WITH other tests, use the +# independent development/test interpreter prepared in Recipe 5: +.venv/bin/python -m pytest tests/ -x --pdb +# Now it pdb-traps at the exact failing test after state accumulated. +``` + +**"My async handler deadlocks."** +```python +# Add at handler entry +import remote_pdb; remote_pdb.set_trace(host="127.0.0.1", port=4444) +``` +Trigger the handler. `nc 127.0.0.1 4444`, then `w` to see the suspended frame, `!import asyncio; asyncio.all_tasks()` to see what else is pending. + +**"Post-mortem on a crash in an Ink child process / subprocess."** +```bash +PYTHONFAULTHANDLER=1 python -m pdb -c continue path/to/entrypoint.py +# On crash, pdb lands at the frame of the exception with full locals +``` diff --git a/skills/software-development/requesting-code-review/SKILL.md b/skills/software-development/requesting-code-review/SKILL.md new file mode 100644 index 0000000..24c20b8 --- /dev/null +++ b/skills/software-development/requesting-code-review/SKILL.md @@ -0,0 +1,285 @@ +--- +name: requesting-code-review +description: "Pre-commit review: security scan, quality gates, auto-fix." +version: 2.1.0 +author: Hermes Agent (adapted from obra/superpowers + MorAlekss) +license: MIT +platforms: [linux, macos, windows] +metadata: + hermes: + tags: [code-review, security, verification, quality, pre-commit, auto-fix] + related_skills: [subagent-driven-development, test-driven-development, github] +--- + +# Pre-Commit Code Verification + +Automated verification pipeline before code lands.

Scoped variants the user may request: +git diff --staged # "staged changes" +git diff HEAD~1 # "the last commit" +git diff main...HEAD # "this branch" / "my PR" +git diff -- src/foo.py # specific file(s) +``` + +If `git diff` and `git diff HEAD` are both empty and there's no git repo or no +changes, fall back to the files the user explicitly named or that were +recently created/edited in this session. If you genuinely can't find any +changed code, say so and stop — there's nothing to simplify. + +Capture the full diff text. Note its size: if it's very large (say >2000 +changed lines), warn the user that four subagents each carrying the full diff +will be token-heavy, and offer to scope it down (per-directory, per-commit) +before proceeding. + +### Phase 2 — Launch four reviewers in parallel + +Use `delegate_task` **batch mode** — pass all four tasks in one `tasks` +array so they run concurrently. Four is the right fan-out for this pattern; +it's within the `delegation.max_concurrent_children` budget on any default +install. + +**No delegation available?** If you can't call `delegate_task` in this +context (you're a leaf subagent, delegation is disabled, or the budget is +exhausted), do NOT skip the review or drop angles. Work through all four +reviewer angles yourself, sequentially, in this context — same search +standards, same finding format. Then say clearly in your final summary that +this was a single-pass inline review, not the parallel fan-out, so the user +knows what actually ran. + +Give **every** reviewer the **complete diff** (not fragments — cross-file +issues hide in the gaps) plus the absolute repo path so they can search the +wider codebase. Each reviewer gets `terminal`, `file`, and `search` +toolsets (so they can `git`, `read_file`, and `search_files`/grep). + +Tell each reviewer to: +- Search the existing codebase for evidence (don't reason from the diff alone). +- **Apply Chesterton's Fence:** before flagging anything for removal, run + `git blame` on the line to understand why it exists. If you can't determine + the original purpose, mark it `confidence: low` — don't guess. +- Report findings as structured output with the concrete cost, confidence, + and risk: + ``` + file:line → problem → cost (what's duplicated/wasted/harder to maintain) → suggested fix | confidence: high/medium/low | risk: SAFE/CAREFUL/RISKY + ``` + The **cost** field forces each finding to justify itself — a finding that + can't articulate what the problem actually costs is probably a nit. + - **SAFE** = proven not to affect behavior (unused imports, commented-out + code, pass-through wrappers). Auto-apply these. + - **CAREFUL** = improves without changing semantics (rename local variable, + flatten nested ternary, extract helper). Apply with test verification. + - **RISKY** = may change behavior or breaks public contracts (N+1 + restructuring, public API rename, memory lifecycle change). Flag for + human review — do NOT auto-apply. +- Skip nits and style-only churn. Only flag things that materially improve + the code. + +Pass these four goals (drop any the user's focus excludes): + +**Reviewer 1 — Code Reuse** +> Review this diff for code that duplicates functionality already in the +> codebase. Search utility modules, shared helpers, and adjacent files +> (use search_files / grep) for existing functions, constants, or patterns +> the new code could call instead of reimplementing. Flag: new functions +> that duplicate existing ones; hand-rolled logic that an existing utility +> already does (manual string/path manipulation, custom env checks, ad-hoc +> type guards, re-implemented parsing). For each, name the existing thing to +> use and where it lives. + +**Reviewer 2 — Code Quality** +> Review this diff for quality problems. Look for: redundant state (values +> that duplicate or could be derived from existing state; caches that don't +> need to exist); parameter sprawl (new params bolted on where the function +> should have been restructured); copy-paste-with-variation (near-duplicate +> blocks that should share an abstraction); leaky abstractions (exposing +> internals, breaking an existing encapsulation boundary); stringly-typed +> code (raw strings where a constant/enum/registry already exists — check the +> canonical registries before flagging); deeply nested conditionals (ternary +> chains, 3+-level if/else pyramids — flatten with guard clauses, early +> returns, or a lookup table); AI-generated slop patterns (extra +> comments restating obvious code like `// increment counter` above `count++`; +> unnecessary defensive null-checks on already-validated inputs; `as any` +> casts that bypass the type system; patterns inconsistent with the rest of +> the file). For each, give the concrete refactor. + +**Reviewer 3 — Efficiency** +> Review this diff for efficiency problems. Look for: unnecessary work +> (redundant computation, repeated file reads, duplicate API calls, N+1 +> access patterns); missed concurrency (independent ops run sequentially); +> hot-path bloat (heavy/blocking work on startup or per-request paths); +> TOCTOU anti-patterns (existence pre-checks before an op instead of doing +> the op and handling the error); memory issues (unbounded growth, missing +> cleanup, listener/handle leaks; long-lived callbacks or objects built as +> closures that capture the whole enclosing scope — everything captured +> stays alive as long as the object does, so prefer a small class or +> explicit-fields struct that copies only what it needs); overly broad reads +> (loading whole files when a slice would do); silent failures (empty catch +> blocks, ignored error returns, `except: pass`, `.catch(() => {})` with no +> handling, error propagation gaps — these hide bugs and should at minimum +> log before swallowing). For each, give the concrete fix and why it's +> faster or safer. + +**Reviewer 4 — Altitude** +> Review this diff for changes implemented at the wrong depth — band-aids +> layered on top of shared infrastructure instead of fixes to the +> infrastructure itself. Signs of a too-shallow fix: a special case added to +> a generic code path to handle one caller (an `if (caller == X)` branch, a +> type check, a magic-value escape hatch); a symptom patched at the call +> site while sibling call sites keep the same flaw; a workaround stacked on +> an earlier workaround; a wrapper added to avoid touching the thing that +> actually needs changing; configuration or flags introduced to route around +> a broken default instead of fixing the default. For each, identify the +> underlying mechanism the change is dodging and describe the deeper fix — +> generalize the shared path, fix the root default, or fix the whole bug +> class — and honestly note when the deeper fix is large enough that it +> should be its own task rather than part of this cleanup. Read the +> surrounding code and `git blame` first: what looks like a band-aid is +> sometimes a deliberate boundary (compat shims, staged migrations, +> vendored-code isolation). Don't flag those. + +### Phase 3 — Aggregate and apply + +Wait for all four to return (batch mode returns them together). + +1. **Merge** the findings into one list, deduping where reviewers overlap — + when two findings target the same line or the same underlying mechanism, + collapse them into one. +2. **Discard false positives** — you have the most context; you don't have to + argue with a reviewer, just drop weak or wrong suggestions silently. +3. **Resolve conflicts.** Reviewers can disagree (Reviewer 1: "use existing + util X"; Reviewer 3: "X is slow, inline it"). Default resolution order: + **correctness > the user's stated focus > readability/reuse > micro-perf.** + Don't apply a perf "fix" that hurts clarity unless the path is genuinely + hot. When two suggestions are mutually exclusive and both defensible, pick + the one that touches less code and note the alternative. +4. **Apply in risk-tier order:** + - **SAFE first** (auto-apply): unused imports, commented-out code, + pass-through wrappers, redundant type assertions. Run tests after. + - **CAREFUL next** (apply with verification, one file at a time): rename + locals, flatten ternaries, extract helpers, consolidate dupes. Run tests + after each file. Revert any that break. + - **RISKY last** (flag for review — do NOT auto-apply): N+1 restructuring, + public API changes, concurrency fixes, error-handling changes. Present + each with risk description and test coverage status. Altitude findings + usually land here — deepening a fix means touching shared + infrastructure, so present the deeper fix and let the user decide + whether to do it now or as a follow-up. + If the user opted for a dry run, present all three tiers and apply nothing. +5. **Verify** you didn't break anything: run the project's targeted tests for + the touched files (not the full suite), and re-run any linter/type check the + repo uses. If a fix breaks a test, revert that one fix and report it. +6. **Summarize** what you changed: a short list of applied fixes grouped by + reviewer category and risk tier, plus any findings you deliberately skipped + and why. If you ran inline (no delegation), say so here. + +## Pitfalls + +- **Don't fan out wider than 4.** More reviewers means more cost and more + conflicting suggestions to reconcile, not better coverage. The four + categories cover the space. +- **Give the WHOLE diff to each reviewer.** Splitting the diff across reviewers + defeats the design — cross-file duplication and N+1s only show up with the + full picture. +- **Reviewers search, they don't guess.** A reuse finding with no pointer to + the existing utility ("there's probably a helper for this") is noise. Require + `file:line` evidence; drop findings that lack it. +- **Apply ≠ rewrite.** This is cleanup of the user's recent changes, not a + license to refactor the whole module. Keep edits scoped to what the diff + touched plus the minimal surrounding change a fix requires. Altitude + findings are the exception that proves the rule: when the right fix is + deeper than the diff, FLAG it — don't unilaterally rebuild the shared + mechanism inside a cleanup pass. +- **Don't drift into bug-hunting.** If a reviewer surfaces a genuine + correctness bug, report it prominently — but as a separate "found a bug" + note, not folded into cleanup fixes. Correctness review is a different + pass with different verification standards. +- **Respect project conventions.** If the repo has AGENTS.md / CLAUDE.md / + HERMES.md or a linter config, fold those rules into the reviewer prompts so + suggestions match house style instead of fighting it. +- **Large diffs blow context.** If the diff is huge, scope it down before + delegating — four subagents each carrying a 5000-line diff is expensive and + may truncate. +- **Over-trusting dead code tools.** `knip`, `ts-prune`, and `depcheck` flag + exports that ARE used dynamically (string-based imports, reflection). Always + grep for the symbol name before removing — a clean tool report is not proof. +- **Renaming without checking public contracts.** Export names, API route + paths, DB column names, and config keys are contracts — even if the name is + bad, renaming breaks consumers. Tag public-contract changes as RISKY; never + auto-rename them. +- **Removing "unnecessary" error handling.** An empty catch block or ignored + error might be intentional — the error is expected and benign in that + context. Flag it, don't remove it; let the human decide. +- **Not every special case is a band-aid.** Compat shims, staged migrations, + and isolation layers around vendored code look like altitude violations but + are deliberate design. Check `git blame` and surrounding comments before + flagging; when the intent is unclear, mark `confidence: low`. + +## Related + +If your install has the `subagent-driven-development` skill (optional), it +covers the complementary case: parallel review *during* implementation, per +task. This skill is the standalone *after-the-fact* cleanup pass. Use +`requesting-code-review` for the pre-commit security/quality gate — that's +the bug hunt; this is the cleanup. diff --git a/skills/software-development/spike/SKILL.md b/skills/software-development/spike/SKILL.md new file mode 100644 index 0000000..cd2d97f --- /dev/null +++ b/skills/software-development/spike/SKILL.md @@ -0,0 +1,197 @@ +--- +name: spike +description: "Throwaway experiments to validate an idea before build." +version: 1.0.0 +author: Hermes Agent (adapted from gsd-build/get-shit-done) +license: MIT +platforms: [linux, macos, windows] +metadata: + hermes: + tags: [spike, prototype, experiment, feasibility, throwaway, exploration, research, planning, mvp, proof-of-concept] + related_skills: [sketch, subagent-driven-development] +--- + +# Spike + +Use this skill when the user wants to **feel out an idea** before committing to a real build — validating feasibility, comparing approaches, or surfacing unknowns that no amount of research will answer.

Read Error Messages Carefully + +- Don't skip past errors or warnings +- They often contain the exact solution +- Read stack traces completely +- Note line numbers, file paths, error codes + +**Action:** Use `read_file` on the relevant source files. Use `search_files` to find the error string in the codebase. + +### 2. Build a Tight Feedback Loop + +- Can you trigger the user's exact symptom with one command? +- Does the command fail for this bug and only pass once the bug is fixed? +- Is it fast enough to run repeatedly? +- Is it deterministic? For flaky bugs, can you raise the reproduction rate high enough to debug? +- If not reproducible → gather more data, don't guess. + +**Ways to construct a loop — try in roughly this order:** + +1. **Failing test** at the seam that reaches the bug: unit, integration, or end-to-end. +2. **HTTP script / curl** against a running dev server. +3. **CLI invocation** with fixture input, diffing stdout/stderr against expected output. +4. **Headless browser script** (Playwright/Puppeteer) asserting on DOM, console, or network. +5. **Replay a captured trace**: HAR, request payload, event log, queue message, or webhook body. +6. **Throwaway harness** that boots the smallest useful slice of the system and calls the failing path. +7. **Property / fuzz loop** when the bug is intermittent wrong output over a broad input space. +8. **Bisection harness** suitable for `git bisect run` when the bug appeared between two known states. +9. **Differential loop** comparing old vs new version, two configs, two providers, or two datasets. +10. **Human-in-the-loop script** only as a last resort: script the human steps and capture their result so the loop stays structured. + +**Tighten the loop once it exists:** + +- Make it faster: cache setup, narrow scope, skip unrelated initialization. +- Make the signal sharper: assert the exact symptom, not generic success. +- Make it more deterministic: pin time, seed randomness, isolate filesystem, freeze network. + +For non-deterministic bugs, the immediate goal is a higher reproduction rate, not perfection. Run the trigger 100x, parallelize, add stress, narrow timing windows, or inject sleeps.

Check Recent Changes + +- What changed that could cause this? +- Git diff, recent commits +- New dependencies, config changes + +**Action:** + +```bash +# Recent commits +git log --oneline -10 + +# Uncommitted changes +git diff + +# Changes in specific file +git log -p --follow src/problematic_file.py | head -100 +``` + +### 4.
