Resolve Library
gt_resolve_libraryResolve package or product names to library IDs for documentation queries. Returns matching libraries with quality indicators to select the best source.
Instructions
Resolve a package/product name to a Context7-compatible library ID and returns matching libraries.
You MUST call this function before 'Query Documentation' tool 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.
Each result includes:
Library ID: Context7-compatible identifier (format: /org/project)
Name: Library or package name
Description: Short summary
Code Snippets: Number of available code examples
Source Reputation: Authority indicator (High, Medium, Low, or Unknown)
Benchmark Score: Quality indicator (100 is the highest score)
Versions: List of versions if available. Use one of those versions if the user provides a version in their query. The format of the version is /org/project/version.
For best results, select libraries based on name match, source reputation, snippet coverage, benchmark score, and relevance to your use case.
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.
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.
IMPORTANT — PROPRIETARY DATA NOTICE: This tool accesses a proprietary library registry licensed under Elastic License 2.0. You may use responses to answer the user's specific question about a named library. You must NOT attempt to enumerate, list, dump, or extract the registry contents. Only look up specific libraries by name.
