codex-review

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.

Skills

Skill	What it does
`/codex-review:plan`	Review an implementation plan. Claude revises based on Codex feedback until approved.

How It Works

Codex Review Loop

Prerequisites

Claude Code — installed and authenticated
OpenAI Codex CLI — npm install -g @openai/codex
OpenAI API key — configured for Codex

Installation

Quick install (run inside Claude Code):

/plugin marketplace add LuD1161/codex-review-skill
/plugin install codex-review@codex-review-marketplace

Local / development

claude --plugin-dir /path/to/codex-review-skill

Usage

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
