Codex Plugin for Claude Code
OpenAI
Codex Plugin for Claude Code lets you invoke OpenAI Codex from inside Claude Code for reviews, adversarial checks, and delegated background tasks.
Key features
- Codex Code Review Slash Commands: /codex:review runs a normal Codex read-only review of uncommitted changes or a branch against a base ref like main.
- Adversarial Review: /codex:adversarial-review runs a steerable review that questions the design and pressure-tests assumptions, tradeoffs, and failure modes.
- Delegated Rescue Tasks: /codex:rescue hands off tasks to a codex-rescue subagent so Codex can investigate bugs, try fixes, or continue previous Codex threads.
- Session Hand-Off: /codex:transfer moves the current Claude Code session over to Codex for continued work, keeping context intact.
- Background Job Management: /codex:status, /codex:result, and /codex:cancel manage long-running Codex jobs kicked off in the background.
