RLS Before Launch: The Supabase Lesson
Most scary vibe-coding security stories are not about genius hackers. They are about public database access with weak or missing Row Level Security.
- 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.
Ask the builder: Enable Row Level Security on every user-owned table. Add policies so authenticated users can only select, insert, update, and delete rows where user_id equals auth.uid(). Show me the policies.- 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?
