What it does
- Launches the target public site with Playwright (Chromium) and collects rendered style primitives.
- Summarizes likely primary/secondary/accent colors, detected fonts, and spacing/radius/shadow scales.
- Generates starter files:
design-system/tokens.jsonanddesign-system/tokens.css, plus raw/normalized JSON artifacts. - Supports
--extract-only(analysis without file generation) andinit(regenerate tokens from existing normalized.json). - Includes explicit safety boundaries: no overwriting existing design systems or config without confirmation.
Who it's for
- Frontend developers bootstrapping design tokens for a new project.
- Designers who want numeric values behind a reference site's look and feel.
- Teams doing early discovery work for a design system migration.
Example uses
- "Extract the design tokens from https://example.com and generate tokens.css" → full run with starter files.
- "Just show me the color palette, don't write files" → runs with
--extract-onlyand summarizes normalized.json. - "Reuse yesterday's normalized.json and rebuild the token files" → runs
extract-design-system init.

Paste this into Claude to use the skill without installing anything.
Read the instructions in this file and follow them to help me: https://raw.githubusercontent.com/arvindrk/extract-design-system/HEAD/skills/extract-design-system/SKILL.md What I want: (describe your task here)
If Claude can't open the link, open it yourself and paste the contents instead.
↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

- Download the ZIP with the button below.
- In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
- Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
Install in Claude Code
Let Claude do it — paste this into Claude Code
Install the skill I found on Claude Skill Mart. Copy the skills/extract-design-system folder from the GitHub repo arvindrk/extract-design-system into my ~/.claude/skills/extract-design-system/. When it's done, tell me in one line what this skill can do.
Install with a command instead
git clone https://github.com/arvindrk/extract-design-system.git && mkdir -p ~/.claude/skills && cp -r extract-design-system/skills/extract-design-system ~/.claude/skills/⚠ This is a third-party skill. Check the source repository before installing.
- Open a terminal.
- Clone the repo:
git clone https://github.com/arvindrk/extract-design-system.git - Create the skills folder:
mkdir -p ~/.claude/skills - Copy the skill:
cp -r extract-design-system/skills/extract-design-system ~/.claude/skills/ - Verify Node.js is installed (
node -v); install it if missing. - Prepare the browser engine:
npx playwright install chromium - Restart Claude Code and ask something like "extract the design tokens from this website".
