Resolve Library Id

resolve-library-id

Resolves a package/product name to a Context7-compatible library ID and returns matching libraries. You MUST call this function before 'query-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: 1. Analyze the query to understand what library/package the user is looking for 2. 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) - Source reputation (consider libraries with High or Medium reputation more authoritative) - Benchmark Score: Quality indicator (100 is the highest score) 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. IMPORTANT: Do not call this tool more than 3 times per question. If you cannot find what you need after 3 calls, use the best result you have.

When to Use

Use this tool when you need to resolves a package/product name to a context7-compatible library id and returns matching libraries.

you must call this function before 'query-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)
source reputation (consider libraries with high or medium reputation more authoritative)
benchmark score: quality indicator (100 is the highest score)

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.
