anydesign-analyzer

Skill by ara.so — Design Skills collection.

anydesign is a Claude skill that analyzes visual sources (images, websites, Figma files) and produces structured design.md files with DTCG-compliant design tokens, component inventories, and reconstruction notes. The output is portable across all AI builders (v0, Lovable, Cursor, Bolt, Claude Code) and design tools.

What it produces

Every analysis generates three artifacts:

1. design.md — 7-section structured document (TL;DR, visual identity, design system, components, layout, reconstruction notes, open questions)
2. design-tokens.json — W3C DTCG format tokens ($value / $type)
3. design-a11y.md (optional) — WCAG 2.1 contrast report

All inferences include confidence levels: ✅ high / ⚠️ medium / ❓ low

Installation

1. Clone and install the skill

# Clone the repository
git clone https://github.com/uxKero/anydesign.git

# Copy to Claude skills directory (personal)
cp -r anydesign ~/.claude/skills/

# OR for project-specific installation
cp -r anydesign /path/to/project/.claude/skills/

2. Install Python dependencies

cd anydesign
pip install -r requirements.txt

# If using capture_site.py for screenshots
playwright install chromium

3. (Optional) Connect Figma MCP

For Figma file analysis, connect the Figma MCP in Claude settings (Settings → Connectors). The skill uses these tools when available:

• get_metadata
• get_variable_defs
• get_design_context
• get_screenshot

Core workflows

Analyze a website

# The skill activates automatically when you provide a URL
# Example prompt:
"Analyze https://vercel.com and create a design.md with full token extraction"

# The skill will:
# 1. Fetch the page HTML
# 2. Extract all CSS custom properties from linked stylesheets
# 3. Capture screenshots (multi-viewport if needed)
# 4. Generate design.md + design-tokens.json

Analyze an uploaded image

# Upload a screenshot or design mockup
# Example prompt:
"Extract the design system from this landing page screenshot"

# The skill will:
# 1. Use vision to identify colors, typography, spacing
# 2. Extract dominant colors via extract_colors.py
# 3. Infer component structure and hierarchy
# 4. Mark each inference with confidence level

Analyze a Figma file

# Requires Figma MCP connection
# Example prompt:
"Analyze this Figma file and check token consistency"

# The skill will:
# 1. Pull variable definitions via get_variable_defs
# 2. Extract usage via get_design_context
# 3. Cross-reference explicit tokens vs actual usage
# 4. Flag inconsistencies in the design.md

Standalone CLI scripts

All scripts in scripts/ work independently of Claude:

Extract CSS variables from any URL

# Basic extraction
python scripts/extract_css_vars.py https://vercel.com/ --pretty

# Save to file
python scripts/extract_css_vars.py https://example.com/ --output tokens.json

# The script:
# - Fetches all linked stylesheets
# - Extracts inline <style> blocks
# - Groups --* custom properties by category (color, spacing, typography, etc.)

Capture multi-viewport screenshots

# Single viewport
python scripts/capture_site.py https://your-site.com --output screenshot.png

# Multiple viewports
python scripts/capture_site.py https://your-site.com \
  --viewports desktop,tablet,mobile \
  --output captures/

# Options:
# --scroll: Enable scroll-capture for lazy-loaded content
# --dismiss-cookies: Auto-dismiss cookie banners

Extract dominant colors from image

# Extract 5 dominant colors
python scripts/extract_colors.py screenshot.png --count 5

# Output as hex codes
python scripts/extract_colors.py image.png --format hex

# Save to JSON
python scripts/extract_colors.py image.png --output colors.json

Check WCAG contrast

# Check single pair
python scripts/check_contrast.py --pair "#111,#FFF"

# Check multiple pairs
python scripts/check_contrast.py \
  --pair "#111,#FFF" \
  --pair "#3B82F6,#FFF" \
  --pair "#EF4444,#FFF"

# From pairs file (one per line: foreground,background)
python scripts/check_contrast.py --pairs-file colors.txt

# Output markdown table
python scripts/check_contrast.py --pair "#111,#FFF" --output contrast-report.md

Validate a design.md

# Lint against spec
python scripts/lint_design_md.py path/to/design.md

# Validates:
# - YAML frontmatter presence
# - {token.refs} resolve correctly
# - 1:1 component mapping
# - Section 6 (reconstruction notes) is non-empty

Audit tokens against live site

# Check if declared tokens match current CSS
python scripts/verify_design.py path/to/design-tokens.json https://vercel.com/

# Reports drift between:
# - Declared token values in JSON
# - Live CSS custom properties on the site

Export for Claude Design

# Generate bundle for claude.ai/design upload
python scripts/export_for_claude_design.py path/to/design.md --out my-brand/

# Produces:
# - brand-kit.pptx (primary asset)
# - brand-overview.docx (full design.md as Word)
# - tokens.css (CSS custom properties)
# - tailwind.config.ts (Tailwind v3 config)
# - README-claude-design.md (upload instructions)

Environment setup

# No API keys required for core functionality
# The skill uses Claude's built-in capabilities

# For Figma analysis, configure MCP in Claude settings
# For Playwright screenshots, ensure chromium is installed:
playwright install chromium

design.md structure

Every generated design.md follows this 7-section format:

---
title: Design System — [Project Name]
source: [URL or file path]
analyzed_at: [ISO timestamp]
confidence_legend: "✅ high / ⚠️ medium / ❓ low"
---

## 1. TL;DR
Three-sentence summary for AI builders and designers

## 2. Visual Identity
Brand personality, color philosophy, typography strategy

## 3. Design System (Tokens)
Colors, typography, spacing, radii, shadows, borders
All with confidence markers and {token.refs}

## 4. Component Inventory
Buttons, inputs, cards, navigation — structured by category

## 5. Layout & Composition
Grid systems, breakpoints, content hierarchy

## 6. Reconstruction Notes
Step-by-step guidance for rebuilding this design

## 7. Open Questions
What requires clarification or additional references

design-tokens.json format

Tokens follow W3C DTCG specification:

{
  "color": {
    "primary": {
      "$value": "#3b82f6",
      "$type": "color",
      "confidence": "high",
      "source": "CSS var(--color-primary)"
    },
    "background": {
      "$value": "#ffffff",
      "$type": "color",
      "confidence": "high"
    }
  },
  "spacing": {
    "unit": {
      "$value": "4px",
      "$type": "dimension",
      "confidence": "medium"
    
     
            
            
            
    
  
   
     
       
         
         
         
      
    
     
            
            
    
  

Real-world examples

Example 1: Analyze Vercel landing page

# Prompt:
"Analyze https://vercel.com and extract the complete design system"

# Output (in examples/vercel-landing/):
# - design.md: Full analysis with 808 extracted CSS variables
# - design-tokens.json: Geist design system in DTCG format
# - design-a11y.md: WCAG contrast report
# - capture.png: Desktop screenshot
# - claude-design-bundle/: Ready for claude.ai/design upload

Example 2: Generate v0 brief from screenshot

# Upload screenshot, prompt:
"Create a design.md I can paste into v0 to build this landing page"

# The skill generates a reconstruction-focused design.md
# Paste into v0.dev → builds working app
# See live demo: https://v0-anydesignexample.vercel.app/

Example 3: Extract tokens for Style Dictionary

# Analyze site
python scripts/extract_css_vars.py https://your-brand.com/ --output raw-tokens.json

# The design-tokens.json is already DTCG-compliant
# Import directly into Style Dictionary:
# config.json:
{
  "source": ["design-tokens.json"],
  "platforms": {
    "css": {
      "transformGroup": "css",
      "buildPath": "build/css/",
      "files": [{
        "destination": "variables.css",
        "format": "css/variables"
      }]
    }
  }
}

Example 4: Audit brand consistency

# After 6 months, check if site still matches captured tokens
python scripts/verify_design.py design-tokens.json https://your-brand.com/

# Output shows:
# - Tokens that match (✓)
# - Tokens that drifted (⚠️ with delta)
# - Tokens no longer present (✗)

Using output with AI builders

Tool	How to consume
v0	Paste entire design.md as project brief
Lovable	Paste design.md, iterate visually
Cursor/Windsurf	Add design.md to context, ask for components
Claude Code	Provide both design.md + design-tokens.json
Bolt	Paste design.md as prompt
Style Dictionary	Import design-tokens.json directly
Figma Variables	Import design-tokens.json (DTCG format)
Tokens Studio	Import design-tokens.json

Common patterns

Pattern 1: Full website capture and tokenization

# 1. Capture screenshots
python scripts/capture_site.py https://example.com \
  --viewports desktop,tablet,mobile \
  --scroll \
  --output captures/

# 2. Extract CSS tokens
python scripts/extract_css_vars.py https://example.com --output raw-tokens.json

# 3. Analyze in Claude
"Using these screenshots and raw-tokens.json, create a complete design.md"

# 4. Validate output
python scripts/lint_design_md.py design.md

# 5. Check contrast
python scripts/check_contrast.py --pairs-file design-tokens.json

Pattern 2: Figma to code workflow

# In Claude with Figma MCP connected:
"Analyze [Figma file URL], check for token consistency, and generate design.md"

# The skill will:
# 1. Pull variable definitions (explicit tokens)
# 2. Extract actual usage (get_design_context)
# 3. Flag discrepancies
# 4. Generate design.md with notes on inconsistencies

# Then feed to v0/Cursor:
"Build this using the attached design.md"

Pattern 3: Brand asset bundle for Claude Design

# 1. Analyze reference
"Analyze our brand homepage and create design.md"

# 2. Export bundle
python scripts/export_for_claude_design.py design.md --out brand-bundle/

# 3. Upload to claude.ai/design:
# - brand-kit.pptx (main asset)
# - brand-overview.docx (brief)
# - tokens.css or tailwind.config.ts (code reference)

# 4. All future Claude Design projects use this brand by default

Troubleshooting

Issue: CSS extraction returns empty

Cause: Site uses inline styles or CSS-in-JS, not CSS custom properties.

Solution:

# Check if site uses custom properties
curl -s https://example.com | grep -o "var(--[^)]*)" | head -5

# If empty, the site doesn't use CSS vars
# Rely on vision-based extraction instead:
"Analyze this screenshot and infer the design system"

Issue: Playwright screenshot fails

Cause: Chromium not installed or site blocks automation.

Solution:

# Reinstall chromium
playwright install chromium

# Try with different user agent
python scripts/capture_site.py https://example.com \
  --user-agent "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7)"

Issue: Token references don't resolve in design.md

Cause: Circular references or malformed {token.ref} syntax.

Solution:

# Validate the design.md
python scripts/lint_design_md.py design.md

# Check design-tokens.json for circular refs
# Fix manually or regenerate

Issue: Figma MCP tools not available

Cause: MCP not connected or insufficient permissions.

Solution:

1. Open Claude settings → Connectors
2. Verify Figma MCP is enabled
3. Check Figma file permissions (must have view access)
4. Retry analysis

Issue: Contrast report shows all failures

Cause: Background color not correctly identified.

Solution:

# Manually specify background
python scripts/check_contrast.py \
  --pair "#3B82F6,#FFFFFF" \
  --background "#FFFFFF"

# Or update design.md with correct background token

Advanced usage

Custom token extraction with filters

# In Python, use extract_css_vars.py as a module
import sys
sys.path.append('scripts')
from extract_css_vars import extract_css_variables

url = "https://example.com"
tokens = extract_css_variables(url)

# Filter only color tokens
color_tokens = {
    k: v for k, v in tokens.items() 
    if k.startswith('--color-') or '#' in v
}

# Convert to DTCG
dtcg = {
    "color": {
        k.replace('--color-', ''): {
            "$value": v,
            "$type": "color"
        }
        for k, v in color_tokens.items()
    }
}

Batch processing multiple sites

# Create a sites.txt with URLs (one per line)
# Then process in batch:

while read url; do
  domain=$(echo $url | sed 's|https://||' | sed 's|/.*||')
  mkdir -p "output/$domain"
  
  python scripts/extract_css_vars.py "$url" \
    --output "output/$domain/tokens.json"
  
  python scripts/capture_site.py "$url" \
    --output "output/$domain/screenshot.png"
done < sites.txt

# Analyze each in Claude:
"For each folder in output/, create a design.md using the tokens.json and screenshot.png"
