## What it does

The skill automates web documentation by crawling an application through Chrome MCP, Playwright MCP, or `playwright-cli`. Before starting, it prompts for the target URL, app name, intended audience, and chosen depth level. The default mode is `standard`, which captures around 30 screenshots and covers primary workflows in 30 to 60 minutes. Shorter runs can use `quick` for about 10 screenshots, while `thorough` and `exhaustive` document edge cases, mobile views at 375px, and administration features.

During the crawl, the browser viewport is resized to 1280x720. The agent verifies that page data has finished rendering before capturing any screen, preventing empty spinners in output files. All images are stored under `docs/screenshots/`, and the written guide is compiled into `docs/USER_GUIDE.md`.

Authentication setup depends on the selected browser tool: Chrome MCP reuses existing browser sessions, whereas Playwright requires login credentials. When choosing target endpoints, the skill prefers deployed production URLs over local development environments.

## Requirements
- Works with: Playwright

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install jezweb/claude-skills app-docs
```

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add jezweb/claude-skills --skill app-docs -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/app-docs/SKILL.md

## When to use it
- generate a structured Markdown user guide for a live web application
- map out an inventory of application routes and navigation sub-menus
- capture consistent 1280x720 screenshots without loading spinners
- document step-by-step user workflows and form submissions

## Example prompts
- Document the app and create a user guide with screenshots
- Generate user docs for our deployed application at standard depth
- Create a quick-start guide for the app using Playwright

# App Documentation Generator

Browse a running web app, screenshot every screen, and produce documentation good enough to publish. Not a screenshot dump — a structured guide that teaches someone how to use the app.

## Browser Tool Detection

Same as ux-audit — Chrome MCP, Playwright MCP, or playwright-cli.

## URL Resolution

Same as ux-audit — prefer deployed/live URL over localhost.

## Depth Levels

| Depth | Screenshots | What it produces | Duration |
|-------|------------|-----------------|----------|
| **quick** | ~10 | Single-page quick-start guide. Key screens, happy path only. | 10-15 min |
| **standard** | ~30 | Full user guide. All pages, primary workflows, reference tables. | 30-60 min |
| **thorough** | ~80+ | Comprehensive guide. All states, mobile views, every CRUD flow, troubleshooting. | 1-3 hours |
| **exhaustive** | ~150+ | Publishable documentation suite. Everything in thorough plus: getting started tutorial, feature-by-feature deep dives, admin guide, keyboard shortcut reference, FAQ, and HTML version. | 3-6 hours |

Default: **standard**

## Workflow

### 1. Get App Details

Ask the user:
- **App URL** (required — or auto-detect from wrangler.jsonc / running dev server)
- **App name** (for the guide title)
- **Auth** — Chrome MCP uses their session; Playwright needs credentials
- **Depth** — quick, standard, thorough, or exhaustive
- **Audience** — who reads this? (end users, admins, new team members, clients)

### 2. Discover All Routes

Navigate the app and build a complete page inventory:
- Read the sidebar/navigation menu
- Click through all top-level items and sub-items
- Note sub-pages, tabs within pages, and nested navigation
- Check for settings, profile, admin areas, help pages
- Record the URL and purpose of each page
- Note which pages have interactive elements (forms, buttons, filters)

Create a task list to track documentation progress.

### 3. Document Each Page

For each page in the inventory:

#### a. Navigate and Prepare
- Navigate to the page
- Wait for data to load (no skeleton/spinner in screenshot)
```
