docs: remove URL support from UI workflow commands
Removed all URL-related parameters and functionality from UI design commands as they are no longer supported. All commands now only accept local files. Changes: - style-extract.md: Removed --urls parameter and all URL mode logic - layout-extract.md: Removed --urls parameter and DOM extraction via URLs - COMMAND_SPEC.md: Deleted capture and explore-layers commands, updated syntax Affected commands: - /workflow:ui-design:style-extract: Only accepts --images and --prompt - /workflow:ui-design:layout-extract: Only accepts --images and --prompt - Removed: /workflow:ui-design:capture (command deleted) - Removed: /workflow:ui-design:explore-layers (command deleted) All UI workflow commands now require manual input of local resources (images, code files, HTML, CSS, JS) instead of fetching from URLs.

**Extraction Script Reference**: `~/.claude/scripts/extract-computed-styles.js`
|
||||
|
||||
**Usage**: Read the script file and use content directly in `mcp__chrome-devtools__evaluate_script()`
|
||||
|
||||
**Script returns**:
|
||||
- `metadata`: Extraction timestamp, URL, method
|
||||
- `tokens`: Organized design tokens (colors, borderRadii, shadows, fontSizes, fontWeights, spacing)
|
||||
|
||||
**Benefits**:
|
||||
- ✅ Pixel-perfect accuracy for border-radius, box-shadow, padding, etc.
|
||||
- ✅ Eliminates guessing from visual analysis
|
||||
- ✅ Provides ground truth for design tokens

## Key Features
|
||||
|
||||
- **Auto-Trigger URL Mode** - Automatically extracts computed styles when --urls provided (no manual flag needed)
|
||||
- **Direct Design System Generation** - Complete design-tokens.json + style-guide.md in one step
|
||||
- **Hybrid Extraction Strategy** - Combines computed CSS values (ground truth) with AI visual analysis
|
||||
- **Pixel-Perfect Accuracy** - Chrome DevTools extracts exact border-radius, shadows, spacing values
|
||||
- **AI-Driven Design Space Exploration** - 6D attribute space analysis for maximum contrast
|
||||
- **Variant-Specific Directions** - Each variant has unique philosophy, keywords, anti-patterns
|
||||
- **Maximum Contrast Guarantee** - Variants maximally distant in attribute space
|
||||
- **Flexible Input** - Images, text, URLs, or hybrid mode
|
||||
- **Graceful Fallback** - Falls back to pure visual inference if Chrome DevTools unavailable
|
||||
- **Flexible Input** - Images, text, or hybrid mode
|
||||
- **Production-Ready** - OKLCH colors, WCAG AA compliance, semantic naming
|
