Design The Data Model First
If the database is vague, the app will be vague. Name the tables, fields, ownership, and privacy rules before asking for screens.
- 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.
Before building screens, propose tables for a tutoring scheduler: students, sessions, tutors, notes. Include owner fields, required fields, and who can read or edit each table.- 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?
