Add the marketplace in Claude Code:

/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
