Codex plugin for Claude Code

Use Codex from inside Claude Code for code reviews or to delegate tasks to Codex.

This plugin is for Claude Code users who want an easy way to start using Codex from the workflow
they already have.



 What You Get

- /codex:review for a normal read-only Codex review
- /codex:adversarial-review for a steerable challenge review
- /codex:rescue, /codex:transfer, /codex:status, /codex:result, and /codex:cancel to delegate work, hand off sessions, and manage background jobs

 Requirements

- ChatGPT subscription (incl. Free) or OpenAI API key.
  - Usage will contribute to your Codex usage limits. Learn more.
- Node.js 18.18 or later

 Install

Add the marketplace in Claude Code:

bash
/plugin marketplace add openai/codex-plugin-cc


Install the plugin:

bash
/plugin install codex@openai-codex


Reload plugins:

bash
/reload-plugins


Then run:

bash
/codex:setup


/codex:setup will tell you whether Codex is ready. If Codex is missing and npm is available, it can offer to install Codex for you.

If you prefer to install Codex yourself, use:

bash
npm install -g @openai/codex


If Codex is installed but not logged in yet, run:

bash
!codex login


After install, you should see:

- the slash commands listed below
- the codex:codex-rescue subagent in /agents

One simple first run is:

bash
/codex:review --background
/codex:status
/codex:result


 Usage

 /codex:review

Runs a normal Codex review on your current work. It gives you the same quality of code review as running /review inside Codex directly.

 [!NOTE]
 Code review especially for multi-file changes might take a while. It's generally recommended to run it in the background.

Use it when you want:

- a review of your current uncommitted changes
- a review of your branch compared to a base branch like main

Use --base  for branch review. It also supports --wait and --background. It is not steerable and does not take custom focus text. Use /codex:adversarial-review when you want to challenge a specific decision or risk area.

Examples:

bash
/codex:review
/codex:review --base main
/codex:review --background


This command is read-only and will not perform any changes. When run in the background you can use /codex:status to check on the progress and /codex:cancel to cancel the ongoing task.

 /codex:adversarial-review

Runs a steerable review that questions the chosen implementation and design.

It can be used to pressure-test assumptions, tradeoffs, failure modes, and whether a different approach would have been safer or simpler.

It uses the same review target selection as /codex:review, including --base  for branch review.
It also supports --wait and --background. Unlike /codex:review, it can take extra focus text after the flags.

Use it when you want:

- a review before shipping that challenges the direction, not just the code details
- review focused on design choices, tradeoffs, hidden assumptions, and alternative approaches
- pressure-testing around specific ri
