# Context7 Documentation Fetcher

This skill fetches up-to-date documentation and code examples from libraries using the Context7 API.

## Standard Workflow

Context7 requires a **two-step process**:

### Step 1: Search for the Library ID

First, search for the library to get its ID:

```
GET https://context7.com/api/v2/libs/search?libraryName=<library>&query=<context>
```

Parameters:

- `libraryName`: The library name (e.g., "react", "nextjs", "fastapi")
- `query`: Search context to help find the right library

The response contains a `results` array with library objects. Use the `id` field from the first result.

### Step 2: Get Documentation Context

Use the library ID to fetch relevant documentation:

```
GET https://context7.com/api/v2/context?libraryId=<id>&query=<question>
```

Parameters:

- `libraryId`: The ID from step 1 (e.g., "/vercel/next.js")
- `query`: Natural language question about the documentation

This returns ranked code snippets and documentation matching your query.

## Example Usage

When the user asks about a library:

1. **Search for the library**:
   Fetch `https://context7.com/api/v2/libs/search?libraryName=nextjs&query=routing`
   Extract the library ID from the response (e.g., "/vercel/next.js")

2. **Fetch documentation**:
   Fetch `https://context7.com/api/v2/context?libraryId=/vercel/next.js&query=How to setup dynamic routes`
3. **Present the results** to the user with the relevant code examples and documentation.

## Tips for Best Results

- Use specific, detailed queries rather than vague terms
- Include relevant context in the query (e.g., "useState hook with TypeScript" instead of just "state")
- The API works without an API key but has restricted rate limits
