If you already use Claude Code, this Codex plugin is a simple way to bring Codex into the same workflow.
It is useful in three cases: a standard Codex review, a more skeptical adversarial review, and handing work off to Codex when you want a second pass from a different agent.

You need a ChatGPT subscription, including Free, or an OpenAI API key, plus Node.js 18.18 or later.
How it works:
The plugin delegates through the local Codex CLI and Codex app server. So it uses the same local auth, config, environment, and MCP setup you already have with Codex.
That is why it feels lightweight. It is not a separate runtime. It is Codex, just invoked from inside Claude Code.
