Overview
OpenAI's official plugin brings Codex capabilities into Claude Code, enabling seamless handoffs between the two agents for code reviews, adversarial reviews, task delegation, and background execution. It formalizes the 'multi-agent developer workflow' where Claude Code writes and iterates, Codex reviews and challenges, and the developer mediates. The plugin provides /codex:review, /codex:adversarial-review, /codex:rescue, and /codex:transfer commands.
Features

- ✓/codex:adversarial-review — challenge implementation decisions
- ✓/codex:rescue — delegate bugs, fixes, or tasks to Codex
- ✓/codex:transfer — move sessions to Codex
- ✓Background execution for long-running tasks
- ✓Review gate for optional PR quality gating
