Type Errors Are Design Feedback
A TypeScript error is often the system telling you the agent guessed the wrong data shape. Read it before suppressing it.
- 1Name the job before naming the tool.
- 2Write the smallest useful scope the agent can finish.
- 3Run the result as a user, not as a fan of the tool.
- 4Inspect the diff, data access, and failure path before sharing.
Use this as the working prompt or checklist for the lesson.
Fix this without `any`: Property 'role' does not exist on type User. Find the real User type and decide whether role belongs there or in a separate Profile.- What should the user be able to do when this is finished?
- What data should the app or agent never expose?
- What test proves the change works?
- What rollback path exists if the output is wrong?
