Codex Plugin for Claude Code lets you 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

`/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. `/codex:adversarial-review` runs a steerable review that questions the chosen implementation and design, helping pressure-test assumptions, tradeoffs, failure modes, and whether a different approach would have been safer or simpler.

## Requirements

- ChatGPT subscription (incl. Free) or OpenAI API key. Usage will contribute to your Codex usage limits.

- Node.js 18.18 or later

- Codex installed and logged in

## Install

Add the marketplace in Claude Code:

```text

/plugin marketplace add openai/codex-plugin-cc

```

Install the plugin:

```text

/plugin install codex@openai-codex

```

Reload plugins:

```text

/reload-plugins

```

Then run `/codex:setup`. It will tell you whether Codex is ready. If Codex is missing and npm is available, it can offer to install Codex for you. You can also install Codex yourself with `npm install -g @openai/codex`, then run `codex login` if Codex is installed but not logged in yet.
