Context7: External Library Documentation

Use Context7 to look up current library APIs instead of guessing from training data.

When to Use

1. Implementing with external libraries - Check current API before writing code
2. Debugging library errors - Verify correct usage patterns
3. User asks "how do I use X" - Get up-to-date examples
4. Uncertain about library API - Don't guess, look it up
5. Library version matters - Context7 has version-specific docs

Workflow

resolve-library-id(libraryName="tokio", query="async runtime spawn tasks")
query-docs(libraryId="/tokio-rs/tokio", query="how to spawn async tasks")
