About Codex Plugin for Claude Code

Codex Plugin for Claude Code is OpenAI's official plugin that lets developers use Codex from within Claude Code to review code or delegate tasks. It bridges two of the most popular AI coding tools, allowing developers to run Codex-quality code reviews on Claude Code output, hand off sessions between agents, and manage background jobs — all without leaving their existing Claude Code workflow.

Key Features

  • Code review via /codex:review runs Codex-quality analysis on Claude Code output
  • Task delegation with /codex:rescue and /codex:transfer for cross-agent handoffs
  • Background job management with /codex:status, /codex:result, and /codex:cancel
  • Optional review gate that blocks Claude Code output until Codex approves changes
  • Automatic Codex CLI installation via /codex:setup if not already present
  • Works with ChatGPT subscriptions (including Free) or OpenAI API keys

Overview

Codex Plugin for Claude Code is OpenAI’s official bridge between two of the most widely used AI coding tools. Released in March 2026, the plugin installs into Claude Code and exposes a set of slash commands that let developers invoke Codex for code review, task delegation, and background job management without switching tools. With Claude Code accounting for an estimated 4% of public GitHub commits, OpenAI built the plugin to meet developers where they already work rather than competing for terminal share.

Key Capabilities

The plugin’s core commands cover three workflows: /codex:review runs a full Codex code review on your current work, /codex:rescue and /codex:transfer delegate tasks or hand off entire sessions to Codex, and /codex:status tracks background jobs. The optional review gate feature automatically blocks Claude Code output until Codex validates the changes, creating a two-agent quality loop.

Use Cases

Development teams use the plugin to add a second opinion to AI-generated code without context-switching. It’s particularly valuable for solo developers who want automated review coverage and for teams evaluating whether Codex or Claude Code performs better on specific task types within the same session.

Considerations

The review gate feature can rapidly consume usage limits when Claude Code and Codex enter correction loops — OpenAI recommends enabling it only under human supervision. Requires a ChatGPT subscription or OpenAI API key in addition to Claude Code access.

Who It’s For

Developers already using Claude Code who want Codex-quality code review as a second pass, or teams exploring multi-agent coding workflows where different AI models handle different stages of development.
