# Context7 Documentation Lookup Skill

Fetch current library documentation, API references, and code examples via the Context7 REST API.

## When to Use

Use this skill when the user asks about library APIs, framework patterns, or version-specific behavior. Trigger on:

- Library questions: "How do I use [library]?", "[library] API docs", "[library] patterns"
- Import statements: `import`, `require`, `from` followed by a library name
- Framework-specific topics: hooks, routing, middleware, ORM queries, schema definitions

## When NOT to Use

Do NOT use this skill for:

- General programming concepts (closures, recursion, design patterns)
- Code review or refactoring tasks
- Debugging business logic
- Writing scripts from scratch without library-specific questions

## Core Workflow

1. **Search** for the library ID:
   ```bash
   scripts/context7.sh search "library-name"
   ```

2. **Pick the best result**: Choose the ID with the highest score and most relevant description. Prefer official sources (e.g., `/vercel/next.js` over community forks).

3. **Fetch documentation** with a focused topic:
   ```bash
   scripts/context7.sh docs "<library-id>" "<topic>" "<mode>"
   ```

Always extract a specific topic from the user's question. For "How does React Suspense work with server components?", use topic `suspense server components`.

## Parameters

| Parameter | Required | Description |
|-----------|----------|-------------|
| `library-id` | Yes | From search results, format `/vendor/library` |
| `topic` | No | Focus area extracted from user query (e.g., `hooks`, `routing`, `validation`) |
| `mode` | No | `code` (default) for API references; `info` for conceptual guides |

## Mode Selection

Use `code` mode (default) when the user asks for API references, code examples, or implementation patterns.

Use `info` mode when the user asks for conceptual explanations, architecture guides, or migration tutorials.

## Examples

```bash
# React hooks API
scripts/context7.sh search "react"
scripts/context7.sh docs "/facebook/react" "hooks" "code"

# Next.js App Router conceptual guide
scripts/context7.sh search "nextjs"
scripts/context7.sh docs "/vercel/next.js" "app router" "info"

# Django ORM queries
scripts/context7.sh search "django"
scripts/context7.sh docs "/django/django" "queryset filter" "code"

# Laravel Eloquent relationships
scripts/context7.sh search "laravel"
scripts/context7.sh docs "/laravel/framework" "eloquent relationships" "code"
```

## Environment Configuration

Set `CONTEXT7_API_KEY` for higher rate limits (optional):

```bash
export CONTEXT7_API_KEY="your-api-key"
```
