Tools
Functions exposed to the LLM to take actions
resolve-library-id
Resolves a package/product name to a Context7-compatible library ID and returns a list of matching libraries.
You MUST call this function before 'get-library-docs' to obtain a valid Context7-compatible library ID UNLESS the user explicitly provides a library ID in the format '/org/project' or '/org/project/version' in their query.
Selection Process:
- Analyze the query to understand what library/package the user is looking for
- Return the most relevant match based on:
- Name similarity to the query (exact matches prioritized)
- Description relevance to the query's intent
- Documentation coverage (prioritize libraries with higher Code Snippet counts)
- Trust score (consider libraries with scores of 7-10 more authoritative)
Response Format:
- Return the selected library ID in a clearly marked section
- Provide a brief explanation for why this library was chosen
- If multiple good matches exist, acknowledge this but proceed with the most relevant one
- If no good matches exist, clearly state this and suggest query refinements
For ambiguous queries, request clarification before proceeding with a best-guess match.
get-library-docs
Fetches up-to-date documentation for a library. You must call 'resolve-library-id' first to obtain the exact Context7-compatible library ID required to use this tool, UNLESS the user explicitly provides a library ID in the format '/org/project' or '/org/project/version' in their query.
