StudioHow to run Codex agents overnight on a Mac and tell finished from cut off
Original title: What do you let an agent run overnight, and how do you know it actually finished?
The author shares their practice for running Codex workers overnight on their own Apple Silicon Mac under a ChatGPT plan: done must be verifiable, coding tasks count only with real test output (one run: 6 tests, OK, exit 0, 55 seconds), research tasks need a saved readable file, and timed-out or cut-off tasks are marked unverified instead of silently retrying. Small tasks each carry their own check, and every retry spends the plan's limits. The author admits it is one Mac and a handful of runs, and notes the unsolved problem of distinguishing finished tasks from half-finished ones after a restart or crash.
The author shares their acceptance rules for running Codex agents overnight, like verifiable done criteria and an unverified state, which can transfer to similar workflows.
