Once connected (see setup above), use the Library Docs tool:
- Ask: "Get the docs for [package], specifically what changed in version [X]"
- Claude retrieves the changelog and migration guide
- Describe your current usage: "I use the X method with Y parameter — does this still work?"
- Claude assesses the impact on your specific code and outlines migration steps
Example Prompt
Try this with Claude using the Library Docs tool
Get the documentation for React Router v7 and tell me what broke compared to v6. I use useNavigate, useParams, and nested routes extensively.
Tips
- Describe your current usage pattern so Claude can assess impact accurately rather than listing all changes
- Ask Claude to rank the breaking changes by severity for your specific use case
- Request a migration checklist you can use to track progress through the upgrade
