# Context7 Documentation Lookup Skill

Fetch current library documentation, API references, and code examples without MCP context overhead.

**Works on all platforms via REST API.**

## When to Use

**Activate automatically when:**

- User asks about library APIs or framework patterns
- User requests code generation using specific libraries/frameworks
- Import statements suggest documentation needs: `import`, `require`, `from`
- Questions about specific library versions or migration
- Need for official documentation patterns vs generic solutions
- Setting up or configuring third-party tools
- "How do I use X library?", "What's the API for Y?"

**Examples:**

- "Create Next.js middleware with authentication" → Use context7
- "Set up Prisma with PostgreSQL" → Use context7
- "Implement Supabase authentication" → Use context7

## Workflow

### Quick Start (If You Know the Library)

**Skip the search** when you already know the library:

```bash
scripts/context7.py docs "/vercel/next.js" "middleware authentication"
```

Common library IDs:

- React: `/facebook/react`
- Next.js: `/vercel/next.js`
- Prisma: `/prisma/prisma`
- Supabase: `/supabase/supabase`
- Express: `/expressjs/express`

### Full Workflow

#### Step 1: Search for Library ID (if unknown)

Search first to get the correct library ID:

```bash
scripts/context7.py search "library-name"
```

Example output shows library IDs you can use:

```txt
ID: /facebook/react
Name: React
Snippets: 2135 | Score: 79.4
```

#### Step 2: Fetch Documentation

```bash
scripts/context7.py docs "<library-id>" "[topic]" "[mode]"
```

**Parameters:**

- `library-id`: From search results (e.g., `/facebook/react`) or known library ID
- `topic`: Optional focus area (e.g., `hooks`, `routing`, `authentication`)
- `mode`: `code` (default) for API/examples, `info` for guides

**Version-Specific Docs:**

```bash
# Request specific version by adding it to the library ID
scripts/context7.py docs "/vercel/next.js/14" "middleware"

# Or mention
