extract-design
Extract the full design language from any website URL. Produces 8 output files including AI-optimized markdown, visual HTML preview, Tailwind config, React theme, shadcn/ui theme, Figma variables, W3C design tokens, and CSS variables. Also runs WCAG accessibility scoring. Use when user says 'extract design', 'get design system', 'design language', 'design tokens', 'what colors/fonts does this site use', 'turn this URL into design tokens', 'make a Tailwind theme from this site', or '/extract-design'. Do not use for building a new UI from scratch unless the user first wants to extract an existing website's design language.

Extract Design Language
Extract the complete design language from any website URL. Generates 8 output files covering colors, typography, spacing, shadows, components, breakpoints, animations, and accessibility.
Prerequisites
Ensure designlang is available. Install if needed:
npm install -g designlang
Or use npx (no install required):
npx designlang <url>
Process
- Run the extraction on the provided URL:
npx designlang <url> --screenshots
For multi-page crawling: npx designlang <url> --depth 3 --screenshots
For dark mode: npx designlang <url> --dark --screenshots
- Read the generated markdown file to understand the design:
cat design-extract-output/*-design-language.md
-
Present key findings to the user:
- Primary color palette with hex codes
- Font families in use
- Spacing system (base unit if detected)
- WCAG accessibility score
- Component patterns found
- Notable design decisions (shadows, radii, etc.)
-
Offer next steps:
- Copy
*-tailwind.config.jsinto their project - Import
*-variables.cssinto their stylesheet - Paste
*-shadcn-theme.cssinto globals.css for shadcn/ui users - Import
*-theme.jsfor React/CSS-in-JS projects - Import
*-figma-variables.jsoninto Figma for designer handoff - Open
*-preview.htmlin a browser for a visual overview - Use the markdown file as context for AI-assisted development
- Copy
