Context7 Instructions

CRITICAL: Use MCP Context7 to access up-to-date library documentation before adding dependencies.

Core Functions

1. resolve-library-id

Resolve a package name to Context7-compatible library ID:

resolve-library-id("tokio") → "/tokio-rs/tokio"
resolve-library-id("react") → "/facebook/react"

2. get-library-docs

Fetch documentation with optional topic filter:

get-library-docs("/tokio-rs/tokio", topic="async")

Workflow

Before adding ANY dependency:

1. resolve-library-id(library_name)
2. get-library-docs(library_id) 
3. Check latest version and security
4. Add dependency with correct version
5. Document choice in commit

Before updating major version:

1. get-library-docs for current version
2. get-library-docs for target version
3. Review breaking changes
4. Plan migration

Best Practices

✅ DO:

• Always check Context7 before adding dependencies
• Use topic parameter for specific info
• Document version choices
• Review security advisories

❌ DON'T:

• Add dependencies without checking latest version
• Skip migration guides on major updates
• Ignore security warnings
