context7

What This Skill Does

Context7 is a sophisticated Model Context Protocol (MCP) tool designed for developers to bridge the gap between their codebase and the vast world of library documentation. It leverages LLM-powered search and reranking to ensure you aren't just searching for keywords, but retrieving actual semantic meaning from official library docs. Whether you are struggling with a complex configuration in Next.js, debugging a hook in React, or implementing an auth flow, Context7 fetches precise snippets and architectural guidance directly into your workflow.

Installation

To integrate Context7 into your OpenClaw environment, execute the following command in your terminal: clawhub install openclaw/skills/skills/thesethrose/context7

After installation, you must configure the environment variables:

1. Copy the example environment file: cp .env.example .env
2. Navigate to context7.com/dashboard to generate your unique API key.
3. Add CONTEXT7_API_KEY=your-key-here to your .env file.
4. Run npm install to ensure all necessary dependencies are resolved.

Use Cases

• Rapid Prototyping: Skip reading through lengthy "Getting Started" guides by querying the specific implementation steps you need.
• Debugging Edge Cases: Retrieve documentation for specific versions of a library to troubleshoot version-mismatch errors.
• Learning New Tech: Use the search functionality to compare libraries or find the most reputable libraries for a specific task using trust and benchmark scores.
• Context Injection: Seamlessly pull documentation into your AI agent's active memory to generate code that adheres to best practices.

Example Prompts

1. "Search for the best authentication library for a Node.js project and give me a summary of how to implement a basic session flow."
2. "Look up the documentation for vercel/next.js regarding server-side rendering setup and provide the code snippet for a basic layout."
3. "I'm using facebook/react, can you check the documentation for useEffect cleanup functions and explain why I need to use them in my event listener hook?"

Tips & Limitations

• Optimize Your Queries: Do not just search for a library name. Always include the specific task or problem (e.g., instead of just "Next.js", search "Next.js setup SSR"). This triggers the LLM-powered ranking for better results.
• Use Exact IDs: If you know the repository, skip searching and call the context command directly with the owner/repo format to reduce latency.
• Version Control: For legacy codebases, use the /owner/repo/version syntax to fetch documentation matching your specific installed dependencies.
• Limitations: This skill requires an active internet connection to query the Context7 API and depends on the accuracy of indexed documentation.
