Provide the library name and your specific question, and the lookup resolves it through Context7 MCP first, then llms.txt endpoints, then web search. You receive the exact API signature, a working code example, and the source URL.

Pass the version string along with the library name and query. The lookup attempts to match version-specific docs and explicitly states when version-specific documentation is unavailable rather than silently returning mismatched information.

llms.txt is an AI-optimized documentation format hosted at predictable URLs like context7.com/{org}/{repo}/llms.txt. Fetching it returns condensed, structured docs, and appending a ?topic= parameter narrows results to a specific subject.

It only returns documentation. The scope guardrail explicitly prevents it from applying changes, writing code, or judging whether an API fits your use case; callers like debug or fix skills handle code changes.

When documentation is sparse but source code is available, the fallback clones the repository and runs repomix to extract API patterns, usage examples, and internal documentation directly from the codebase.
