What this skill tells the agent

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

  1. 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

  1. Read the generated markdown file to understand the design:
cat design-extract-output/*-design-language.md
  1. 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.)
  1. Offer next steps:
  • Copy *-tailwind.config.js into their project
  • Import *-variables.css into their stylesheet
  • Paste *-shadcn-theme.css into globals.css for shadcn/ui users
  • Import *-theme.js for React/CSS-in-JS projects
  • Import *-figma-variables.json into Figma for designer handoff
  • Open *-preview.html in a browser for a visual overview
  • Use the markdown file as context for AI-assisted development
