Give Your Builder A Rules File
A project rules file tells the AI your conventions before it touches anything: names, colors, auth rules, forbidden actions, and how to verify work.
- 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.
Create PROJECT_RULES.md: Do not store secrets in frontend code. Use our existing Button component. Run npm run typecheck after edits. Never delete data migrations without asking.- 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?
