Library Docs

Library Documentation Research

Purpose

Retrieve up-to-date docs from authoritative sources before coding against third-party APIs.

Core Workflow

1. Resolve library id with mcp__context7__resolve-library-id
2. Choose best match by name relevance, trust score, and snippet coverage
3. Fetch docs with mcp__context7__get-library-docs
4. Extract concrete API usage patterns and examples relevant to the task

Retrieval Guidance

• Use focused topic queries when possible ("routing", "migrations", "cli options")
• Start around 5000 tokens; increase for broad API or migration work
• Prefer official library/project docs over blogs

When to Use

Use this skill first for:

• Any new dependency integration
• API changes or deprecations
• Migration/version-upgrade tasks
• Verifying exact signatures/options before implementation

Failure Handling

If no strong library match is found:

1. Try alternate package/project names
2. Query broader topic scope
3. Fall back to primary-source web docs (official site/repo)
