How to Look Up Package Docs with Copilot
Access library documentation in your IDE with Copilot and ToolRouter. Get current package docs without switching tabs.

Steps
Once connected (see setup above), use the Library Docs tool:

- Copilot fetches current documentation
- Ask: "Show me the correct way to use [specific method]"
- Implement the feature with accurate, current API knowledge
Example Prompt
Try this with Copilot using the Library Docs tool
Get the current docs for the prisma client package and show me how to write a query that fetches all users where the role is "admin" and the createdAt is in the last 30 days.
Tips
- Ask for docs while you are writing the code that uses the package — stay in flow
- Request the TypeScript types for a method to get accurate autocomplete in your editor
- Check docs for packages you have not used recently to confirm API signatures have not changed
