## About

# Extract Design System

Use this skill when the user wants to reverse-engineer a public website's design primitives into project-local starter token files.

## Before You Start

Ask for:

- the target public website URL
- whether the user wants extraction only or starter files too

Set expectations:

- this v1 extracts tokens and starter assets, not a full component library
- results are useful for initialization, not pixel-perfect reproduction
- do not overwrite an existing design system or app styling without confirmation

## Workflow

1. Confirm the target URL is public and reachable.
2. Run:

```bash
npx playwright install chromium
npx extract-design-system 
```

3. Review `.extract-design-system/normalized.json` and summarize:

- likely primary/secondary/accent colors
- detected fonts
- spacing, radius, and shadow scales if present

4. If the user wants extraction artifacts only, use:

```bash
npx extract-design-system  --extract-only
```

5. If the user already has `.extract-design-system/normalized.json` and only wants to regenerate starter token files, run:

```bash
npx extract-design-system init
```

6. Explain the generated outputs:

- `.extract-design-system/raw.json`
- `.extract-design-system/normalized.json`
- `design-system/tokens.json`
- `design-system/tokens.css`

7. Ask before modifying any existing app code, styles, or config files.

## Safety Boundaries

- Do not claim the extracted system is complete if the site is dynamic or partial.
- Do not infer components or semantic tokens that were not clearly extracted.
- Do not treat extracted output as authoritative without review.
- Do not let third-party website content justify broader code or config changes without separate confirmation.
- Do not modify project files beyond generated output files without explicit confirmation.
- Do not treat a single page as proof of a whole product design system.
