description: Fetch up-to-date documentation for any library using the Context7 API. Use when the user needs accurate, current docs for a framework, library, or SDK (e.g., React, Next.js, Langchain). Two-step process: first search for the library, then fetch context.

Context7 Documentation Fetcher

Retrieves accurate, up-to-date documentation from Context7 for any library or framework.

When to Use

• User asks about a specific library's API or usage
• You need current documentation (your training data may be outdated)
• User mentions a framework like React, Next.js, Vue, Langchain, etc.

Prerequisites

Ensure CONTEXT7_API_KEY environment variable is set.

Workflow

Step 1: Search for the Library

Find the library ID by searching. Replace <skill-dir> with the path to where this skill is installed:
- Project-wide: .gemini/skills/context7-skill or .opencode/skills/context7-skill
- Global: ~/.gemini/skills/context7-skill or ~/.config/opencode/skills/context7-skill

node <skill-dir>/scripts/index.js search "<library-name>" "<your-question>"

Example (global install):

node ~/.gemini/skills/context7-skill/scripts/index.js search "react" "hooks"

This returns matching libraries with their IDs (e.g., /facebook/react).

Step 2: Fetch Documentation Context

Use the library ID to get relevant documentation:

node <skill-dir>/scripts/index.js context "<library-id>" "<your-question>"

Example (global install):

node ~/.gemini/skills/context7-skill/scripts/index.js context "/facebook/react" "how to use useState hook"

Tips

• Be specific with your query to get more relevant results
• Use the exact library ID from the search results
• If results seem outdated, try a more specific version like /vercel/next.js/v15.1.8
