According to OpenAIDevs on X, auto-review is now live in Codex, using a guardian agent to assess the safety of proposed actions so human approvals are only required when necessary. As reported by OpenAIDevs, the new mode lets Codex run longer workflows—tests, builds, and automations—with fewer interruptions while a separate agent inspects higher‑risk steps in context before execution. According to Greg Brockman on X, this design aims to increase throughput for software CI CD pipelines and long-running devops tasks while improving safety coverage. For businesses, the opportunity is faster development cycles, lower reviewer load, and safer agentic automation for code changes and deployment steps, according to the announcement posts on X.
