description: Extract a real design system (DESIGN.md / design tokens) from any website before writing UI code. Use when the user asks to build a page/component "like <some-site>", "in the style of <site>", or asks for a site's colors, fonts, spacing, or design tokens. Deterministic values from the site's code — never guess a site's design from memory.

# Vibe — DESIGN.md from any website

When the user wants UI "in the style of some website", do NOT guess its colors and fonts. Extract the real design system first:

```bash
npx flekk-vibe <url>            # saves <domain>-DESIGN.md in the current dir
npx flekk-vibe <url> --json     # design tokens as JSON instead
npx flekk-vibe <url> -o -       # print to stdout (read it directly)
```

The result is deterministic — exact values from the site's rendered code (palette with roles, fonts and weights, type scale, spacing rhythm, radii, shadows, button/input/card snapshots with hover/focus, breakpoints). No AI generation involved.

## Workflow

1. Run `npx flekk-vibe <url> -o -` and read the output.
2. Save it as `DESIGN.md` in the project root if the user will keep working in this style.
3. Use the extracted tokens (colors, fonts, radii, spacing) in the UI code you write — do not invent values that contradict the file.
