extract-design-system
Reverse-engineer a design system from a live website (public URL or localhost). Extracts colors, typography, spacing, shadows, radii, breakpoints, and component patterns using a headed Playwright browser. Captures screenshots of pages, components, and interactive states at real device resolutions. Produces structured design tokens and optionally seeds a Penpot project. **Triggers — use this skill when:** - User says "extract design system from [url]" - User asks to "reverse-engineer the styles from [site]" - User says "build a design system based on [website]" - User asks to "pull the design tokens from [url]" - User says "analyze the design of [site]" - User asks to "import styles from [website] into Penpot" - User points at a URL and asks about its colors, fonts, spacing, or components

# Extract Design System from Website
Reverse-engineer a complete design system from a live website using two passes:
1. **CSS source analysis** — fetch and parse stylesheets for declared values
2. **Headed Playwright extraction** — visually browse the site, interact with elements,
extract computed styles, and capture screenshots at real device resolutions
## Prerequisites
- Playwright installed (`npx playwright install chromium` if not set up)
- `web_fetch` tool for fetching raw HTML/CSS source
## Quick Start
