+# brandmd
+
+Extract a live website's design system into a DESIGN.md file for use with Stitch.
+
+## Install
+
+```bash
+npx skills add google-labs-code/stitch-skills --skill brandmd --global
+```
+
+## Usage
+
+Tell your agent:
+
+> "Extract the design system from https://linear.app and use it for my Stitch project"
+
+The skill runs `npx brandmd <url>` to extract colors, typography, spacing, and component styles, then outputs a DESIGN.md that Stitch can use for on-brand screen generation.
+
+## How it complements other skills
+
+- **design-md**: Documents design systems from existing Stitch projects
+- **brandmd**: Imports design systems from live websites into the Stitch workflow
+- **enhance-prompt**: Uses the extracted DESIGN.md tokens to optimize Stitch prompts
+- **stitch-design**: Generates screens using the DESIGN.md as context
+
+## Requirements
+
+- Node.js 18+
+- npx (comes with Node.js)
+- brandmd installs automatically on first run

+
+# brandmd: Website to DESIGN.md
+
+You extract a live website's design system into a DESIGN.md file that Stitch can use to generate on-brand UI.
+
+This skill complements the `design-md` skill. While `design-md` documents design systems from existing Stitch projects, `brandmd` imports design systems from live websites into the Stitch workflow.
+
+## When to use
+
+- User wants to generate Stitch screens matching an existing website's brand
+- User says "use the same design as [url]" or "match this website"
+- Starting a new Stitch project for a client who has an existing site
+- User needs a DESIGN.md but doesn't have a Stitch project yet
+
+## Prerequisites
+
+Node.js 18+ must be available. The tool installs automatically via npx on first run.
+
+## Extraction
+
+Run brandmd to extract the design system from the target URL:
+
+```bash
+npx brandmd <url> -o DESIGN.md
+```
+
+Pass the most design-rich page for best results. The homepage is usually the best choice. The tool renders the page in a headless browser, scrolls through lazy-loaded content, dismisses cookie banners, and extracts computed styles from every visible element.
+
+### What it extracts
+
+- **Colors** clustered by similarity with semantic roles (background, text, accent, border)
+- **Typography** with font families, size scale grouped by heading/body/caption, and weights
+- **Spacing scale** with base grid unit detection
+- **Border radii** and shadow styles
+- **Component patterns** for buttons, cards, and inputs
+
+### Output format
+
+The output follows the DESIGN.md 5-section format:
+
+1. Visual Theme & Atmosphere
+2. Color Palette & Roles
+3. Typography Rules
+4. Component Stylings
+5. Layout Principles
+
+## Integration with Stitch
+
+After extraction:
+
+1. Read the generated DESIGN.md
+2. Review the extracted tokens with the user (colors, fonts, spacing)
+3. Use the DESIGN.md as context for Stitch screen generation via the `stitch-design` or `enhance-prompt` skills
+4. When calling `[prefix]:generate`, reference specific tokens from DESIGN.md in the prompt (e.g. "use the primary font sohne-var, accent color #533AFD, 4px spacing grid")
+
+## Options
+
+- `npx brandmd <url>` — output to stdout
+- `npx brandmd <url> -o DESIGN.md` — save to file
+- `npx brandmd <url> --json` — raw tokens as JSON for programmatic use
+
+## Limitations
+
+- Extracts from a single page, not the entire site
+- Cannot read Figma tokens or design tool files
+- Color role assignment is heuristic based on usage frequency and luminance
+- Requires a publicly accessible URL (no auth-gated pages)
+- The extracted DESIGN.md is a starting point. Review and adjust color roles and component styles before using in production.
