🔁 Make the AI run your checks
Writes down the checks you normally do by hand, so the AI runs them after every change and must fix any failure before it moves on.
Use it when: You keep catching the same mistakes by hand after the AI says it's done.
🛑 Stops when: All your checks pass after the latest change, or it gets stuck on the same failure twice.
Copy this loop
Here are the checks I usually run by hand after a change: [build, tests, type check, open the page and look at X]. Turn each one into a command or step you can run yourself. Add them to [project instructions file or hooks] so they run after every change you make. From now on, after each change: run every check. If one fails, fix it before doing anything else. Do not skip, weaken, or delete a check to make it pass. If the same check fails twice in a row for the same reason, stop and show me the error. Stop when all checks pass, or after [10] fix rounds. Show me the list of checks you set up.
Review every change the agent makes before you keep it. Set a budget or round limit — the prompt includes one.
