## What it does

The skill traverses every route it can reach: navigation, lists, forms, modals, empty and error states, keyboard shortcuts, responsive layouts at 768 and 375, motion. Interface copy is recorded word for word, down to button labels and error messages. What comes out is a document other audits point at.

It is the inverse of `ux-audit`. An audit asks whether your build matches the bar; extract first works out where the bar sits. Skip that step and the audit ends up comparing against your memory of other apps, which drifts between runs.

Authenticated pages need Chrome MCP running on your logged-in session, public ones work with Playwright MCP. On Retina Macs Chrome captures at twice the logical viewport, so the author suggests `img-process batch ./screenshots --action optimise --max-width 1440`; Playwright MCP users can set `deviceScaleFactor: 1` instead. Check `robots.txt` and the service terms before you start — automated scraping of someone else's interface is usually off limits, and screenshots of a live competitor belong in internal docs, not on a public page.

## Requirements
- Works with: Playwright

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add jezweb/claude-skills --skill ux-extract -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/ux-extract/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/ux-extract/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add jezweb/claude-skills --skill ux-extract -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/ux-extract/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add jezweb/claude-skills --skill ux-extract -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/ux-extract/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install jezweb/claude-skills ux-extract
```

2. **Manually: put the files in place**
- File: `.github/skills/ux-extract/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add jezweb/claude-skills --skill ux-extract -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/jezweb/claude-skills --path plugins/dev-tools/skills/ux-extract
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/ux-extract/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add jezweb/claude-skills --skill ux-extract -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/jezweb/claude-skills/tree/HEAD/plugins/dev-tools/skills/ux-extract/SKILL.md

## When to use it
- build a UX pattern library from a reference app
- capture every screen state, including empty and error views
- record interface copy verbatim for later comparison
- get a reference before starting a new feature
- document a competitor's responsive and motion behaviour

## Example prompts
- learn from X and build a pattern library
- extract patterns from X: empty states, errors, keyboard shortcuts
- study X's UX, then we'll audit our dashboard against it

# UX Extract

Exhaustively study a reference web app and produce a reusable pattern library. Goes everywhere, captures everything, then organises it into a document another audit or build can reference.

The inverse of `ux-audit`:
- **Audit** asks: *does this match a bar?*
- **Extract** asks: *what is the bar?*

Audits without extracts implicitly compare to "my memory of other apps" — fragile and inconsistent. Extracts turn that memory into a concrete, navigable artifact. An audit can then say: *"Empty state on /app/clients shows no CTA. Reference (claude.ai) shows 3 keyboard shortcuts plus 'New chat' in the same position"* instead of *"feels a bit sparse"*.

## When to use

- **Before building a new feature** — study how best-in-class apps handle it
- **Benchmarking a build** — extract the reference, then audit against it
- **Onboarding designers or engineers** — here's what good looks like, concretely
- **Competitor research** — document the competitor's UX so you can meaningfully differentiate
- **Refreshing an old app** — extract patterns from modern equivalents to guide the update

## Scope and ethics

Before starting, confirm the target is fair game:

1. **Use your own account** — don't scrape anything that requires credentials you don't legitimately hold
2. **Respect `robots.txt`** for unauthenticated crawling
3. **Rate-limit** — act like a human user, not a crawler. Pause between pages.
4. **Check ToS** — most SaaS Terms of Service permit individual inspection but prohibit automated scraping
5. **Don't redistribute** screenshots of a live competitor's app publicly — pattern libraries are internal references

If the target is behind a paywall or requires a trial account, ask the user whether they have legitimate access before proceeding.

## Setup

### 1. Browser tool

| Target | Tool | Notes |
|--------|------|-------|
| **Authenticated reference** (you have an account) | Chrome MCP | Uses your logged-in session |
| **Public reference** (marketing pages, docs, public demos) | Playwright MCP | No login needed |
```
