OpenAI's own playbook for running Codex for days, not minutes

The interesting part isn't the hours, it's the shift in habit: stop treating the agent like a one-shot prompt and start handing it a multi-day ticket, then checking in. That only works if you've broken the goal into steps you can actually verify — OpenAI's own write-up admits unsupervised sprawl is still the failure mode to watch. Worth trying on one real backlog item this week, with a clear checkpoint, before trusting it with anything that ships straight to production.
