According to 1M AI News monitoring, Romain Huet, OpenAI’s Head of Developer Experience, said on X that OpenAI has open-sourced a Claude Code plugin. Users can directly call Codex in Claude Code to complete code reviews with a ChatGPT subscription, or delegate tasks to Codex.
The plugin author, Dominik Kundel, wrote that the plugin lets Codex review code changes, and also allows tasks to be handled by Codex within Claude Code. The GitHub README shows that the plugin provides commands such as /codex:review, /codex:adversarial-review, /codex:rescue, /codex:status, /codex:result, and /codex:cancel. It supports both read-only reviews and background task delegation.
The README also states that the plugin can be installed via the Claude Code plugin marketplace, requiring a ChatGPT subscription (including Free) or an OpenAI API key, as well as Node.js 18.18 or higher.
