Summary

The Codex plugin for Claude Code integrates OpenAI's Codex capabilities directly into the Claude Code workflow, enabling users to perform code reviews and delegate coding tasks. It offers commands like "/codex:review" for standard read-only reviews and "/codex:adversarial-review" for steerable, challenge-focused reviews that pressure-test design choices. Users can delegate tasks such as bug investigation or fixes using "/codex:rescue", with options to specify models like "gpt-5.4-mini" or "gpt-5.3-codex-spark" and effort levels. The plugin also provides commands for managing background jobs ("/codex:status", "/codex:result", "/codex:cancel") and transferring Claude Code sessions to Codex via "/codex:transfer". Installation requires Node.js 18.18 or later and a ChatGPT subscription or OpenAI API key, with usage contributing to Codex limits. Configuration can be customized through "config.toml" files. A "review gate" feature can block Claude's responses if issues are detected.

Key takeaway

For AI Engineers or Software Engineers using Claude Code, integrating the Codex plugin streamlines development by embedding AI-driven code review and task delegation directly into your IDE. You should install this plugin to access advanced review capabilities, including adversarial checks on design choices. This allows you to offload debugging or fix tasks to Codex, potentially accelerating your development cycles. Be mindful that the optional review gate can create long-running loops and quickly consume usage limits.
