# Context7 Docs - Library Documentation

Fetch up-to-date library documentation via the Context7 MCP server. Use this skill when you need to research any npm library, framework, or tool.

## Quick Reference

| Action | Command | Description |
|--------|---------|-------------|
| search | `./scripts/docs.sh search <library>` | Find library ID for a given name |
| docs | `./scripts/docs.sh docs <library> [topic] [--tokens N]` | Get documentation for a library |
| help | `./scripts/docs.sh help` | Show usage help |

## How to Use

### Natural Language
- "Get React hooks documentation"
- "Search for Next.js App Router docs"
- "Find Vue 3 composition API documentation"
- "Look up Tailwind CSS utilities"

### Script Commands
```bash
# Search for a library
./scripts/docs.sh search react
./scripts/docs.sh search "next.js"

# Get documentation (automatically resolves library ID)
./scripts/docs.sh docs react hooks
./scripts/docs.sh docs next.js "app router"
./scripts/docs.sh docs tailwindcss utilities

# Get general documentation without topic filter
./scripts/docs.sh docs vue
```

## Available Actions

### search
Find the Context7-compatible library ID for a given library name.

**Parameters:**
- `library` (required): Library name to search for (e.g., "react", "next.js")

**Example:**
```bash
./scripts/docs.sh search react
# Returns: /npm/react, /websites/react_dev, etc.
```

### docs
Get documentation for a library, optionally filtered by topic.

**Parameters:**
- `library` (required): Library name (will be resolved to ID automatically)
- `topic` (optional): Topic to filter documentation (e.g., "hooks", "routing")

**Example:**
```bash
# Get React hooks documentation
./scripts/docs.sh docs react hooks

# Get general Next.js documentation
./scripts/docs.sh docs next.js

# Get specific Vue documentation
./scripts/docs.sh docs vue "composition api"
```

## Workflow

This skill encodes the Context7 two-step workflow:

1. **Resolve Library ID**: Converts human-readable library name to Context7 ID
2. **Fetch Documentation**: Gets documentation using the resolved ID

This is handled automatically by the `docs` action.

## Supported Libraries

Context7 supports thousands of libraries including:
- **Frontend**: React, Vue, Angular, Svelte, Solid
- **Meta-frameworks**: Next.js, Nuxt, Remix, Astro, SvelteKit
- **Styling**: Tailwind CSS, styled-components, Emotion
- **State**: Redux, Zustand, Jotai, Pinia
- **Backend**: Express, Fastify, Hono, Nest.js
- **Databases**: Prisma, Drizzle, TypeORM, Mongoose
- **Testing**: Jest, Vitest, Playwright, Cypress
- **And many more...**

## Prerequisites

- Node.js 18+ installed
- curl installed
- **Option A:** Install MCPorter via Homebrew: `brew tap steipete/tap && brew install mcporter`
- **Option B:** Use via npx (no install required): `npx mcporter`

> **Note:** Context7 server configuration is optional. The skill automatically falls back to the Context7 public URL (`https://mcp.context7.com/mcp`) if no local server is configured.

## Environment Variables

- `CONTEXT7_SERVER`: MCP server name (default: `context7`)
- `CONTEXT7_API_BASE`: Direct Context7 REST base URL (default: `https://context7.com/api/v2`)
- `CONTEXT7_REST_FALLBACK`: Enable direct REST fallback when MCP calls fail (default: `1`)
- `MCPORTER_TIMEOUT`: Timeout in seconds for MCPorter calls (default: `20`)

## Notes

- Use this skill BEFORE searching external documentation
- Topic filtering helps reduce context size - use specific topics when possible
- Use `--tokens N` to control response size when context budget is tight
- If a library isn't found, try alternative names (e.g., "nextjs" vs "next.js")
- For generic MCP access, use the `mcporter` skill instead
- Falls back to Context7 public MCP URL when server not configured locally
- If MCP calls fail (including quota exhaustion), falls back to direct Context7 REST API when enabled
