Let Claude and Codex review each other's work.
/codex-review:plan
Review an implementation plan. Claude revises based on Codex feedback until approved.
/codex-review:code
Review code changes from the current session. Claude fixes issues until approved.
Run /codex-review:plan or /codex-review:code in Claude Code.
Claude collects your plan or git diff and sends it to Codex CLI for review.
Codex checks for bugs, security issues, performance problems, and correctness.
Claude addresses Codex's feedback and sends the revised version back. Up to 5 rounds.
Once Codex is satisfied, you get the green light to ship.
