Brief

/goal in Codex lets you assign a mission, specify what “done” means, and let the model run continuously until it reaches the end state. @reach_vb (2026-05-08) pitches it as ideal for big refactors, migrations, retry loops and long-running experiments; enable it in /experimental and view the demo video.

/goal in Codex is wild!

Give Codex the mission.
Tell it what “done” looks like.
Let it keep going until it hits the end state.

Perfect for big refactors, migrations, retry loops, long-running experiments, and all the “don’t stop until this works” tasks.

Enable it in /experimental and try it on your next long-running task. Enjoy!
