Extracts the visual theme (colors, typography, radius, spacing, shadows) of a public website provided by the user and produces a shadcn/ui + Tailwind CSS v4 compatible token block, ready to paste into the project's `globals.css` (or `app.css`) inside `@theme` and `.dark`. Uses the `agent-browser` CLI to drive a real Chromium instance. Use when the user asks to "extract the theme of <url>", "reverse-engineer the design tokens of <site>", "copy the look of <site> into shadcn…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Extract Theme (URL → shadcn/ui + Tailwind v4 `@theme`)

Reverse-engineer the **visual theme** of a public website into a token block that drops straight into a project using **shadcn/ui** and **Tailwind CSS v4**. Output is scoped to design tokens — colors, typography, radius, spacing, shadows. No components are generated.

## When to use

- The user provides a URL and wants to "extract the theme", "match the look", "copy the design tokens", or "scaffold a shadcn theme from this site".
- The current project already uses (or is about to use) shadcn/ui with Tailwind v4 (`@import "tailwindcss"` + `@theme`).
- The user wants a starter theme, not a pixel-perfect clone.

## When not to use

- The user wants a full component port (use `shadcn` + `tailwind-design-system` skills directly).
- The site is private, requires auth, or is behind a heavy SPA shell that does not paint a meaningful first frame (extraction quality will be low — say so).
- The project is on Tailwind v3 — the output uses v4-only syntax (`@theme`, `@custom-variant`, OKLCH variables). Refuse and point at the v3→v4 migration.

How to install

The exact contents, by fingerprint
mdr add firzus/agent-skills/extract-theme@sha256:9cff783601665fd4

The line at the top of this page pins the label git:20260722.b16c457, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
