Design Context Extract Skill

Design Context Extract

Extract the "Design DNA" from existing applications — colors, typography, spacing, and component patterns — and output as structured tokens.

/ork:design-context-extract /tmp/screenshot.png       # From screenshot
/ork:design-context-extract https://example.com        # From live URL
/ork:design-context-extract current project            # Scan project's existing styles

Step 0: Detect Input and Context

INPUT = ""

TaskCreate(subject="Extract design context: {INPUT}", description="Extract design DNA")

# Determine input type
# "/path/to/file.png" → screenshot
# "http..." → URL
# "current project" → scan project styles

Step 1: Capture Source

For screenshots: Read the image directly (Claude is multimodal).

For URLs:

# If stitch available: use get_screen + get_project
# If not: WebFetch the URL and analyze HTML/CSS

For current project:

Glob("**/tailwind.config.*")
Glob("**/tokens.css")
Glob("**/*.css")  # Look for design token files
Glob("**/theme.*")
# Read and analyze existing style definitions

Step 2: Extract Design Context

If stitch MCP is available:

# Use official Stitch MCP tools: get_screen, get_project, list_screens
# Returns structured design data: colors, typography, layout, components

If stitch MCP is NOT available (fallback):

# Multimodal analysis of screenshot:
# - Identify dominant colors (sample from regions)
# - Detect font families and size hierarchy
# - Measure spacing patterns
# - Catalog component types (cards, buttons, headers, etc.)
#
# For URLs: parse CSS custom properties, Tailwind config, computed styles

Extracted data structure:

{
  "colors": {
    "primary": { "hex": "#3B82F6", "oklch": "oklch(0.62 0.21 255)" },
    "secondary": { "hex": "#10B981", "oklch": "oklch(0.69 0.17 163)" },
    "background": { "hex": "#FFFFFF" },
    "text": { "hex": "#1F2937" },
    "muted": { "hex": "#9CA3AF" }
  },
  "typography": {
    "heading": { "family": "Inter", "weight": 700 },
    "body": { "family": "Inter", "weight": 400 },
    "scale": [12, 14, 16, 18, 24, 30, 36, 48]
  },
  "spacing": {
    "base": 4,
    "scale": [4, 8, 12, 16, 24, 32, 48, 64]
  },
  "components": ["navbar", "hero", "card", "button", "footer"]
}

Step 3: Choose Output Format

AskUserQuestion(questions=[{
  "question": "Output format for extracted tokens?",
  "header": "Format",
  "options": [
    {"label": "Tailwind config (Recommended)", "description": "tailwind.config.ts with extracted theme values"},
    {"label": "W3C Design Tokens", "description": "design-tokens.json following W3C DTCG spec"},
    {"label": "CSS Variables", "description": "tokens.css with CSS custom properties"},
    {"label": "Markdown spec", "description": "Human-readable design specification document"}
  ],
  "multiSelect": false
}])

Step 4: Generate Output

Write the extracted tokens in the chosen format. If the project already has tokens, show a diff of what's new vs existing.

Anti-Patterns

NEVER guess colors without analyzing the actual source — use precise extraction
NEVER skip the oklch conversion — all colors must have oklch equivalents
NEVER output flat token structures — use three-tier hierarchy (global/alias/component)
