Let Claude and Codex review each other's work.

---

A Claude Code plugin that sends your plans and code to OpenAI Codex CLI for iterative, multi-round review. Claude and Codex go back-and-forth — fixing, refining, and improving — until Codex approves.

Review a plan

/codex-review:plan

Send your implementation plan to Codex. Claude automatically revises the plan based on feedback until Codex approves.

Review code changes

/codex-review:code

Gather the git diff from your session and send it to Codex. Claude automatically fixes issues Codex finds.

Override the model

Both skills accept a model argument:

/codex-review:plan o4-mini
/codex-review:code o4-mini

Configuration

Option	Default	Description
Model	gpt-5.3-codex	Override per-invocation via arguments
Max rounds	5	Prevents infinite review loops
Sandbox	read-only	Codex can read your codebase but never writes
