// summary

This plugin allows Claude Code users to invoke Codex directly within their workflow for code reviews or task delegation. Users can execute read-only reviews, adversarial reviews, and background task management through a series of slash commands. The tool leverages the locally installed Codex CLI and existing authentication configurations, ensuring seamless integration with the user's current development environment.

// technical analysis

The Codex plugin for Claude Code is a plugin designed to seamlessly integrate the powerful capabilities of Codex into the Claude Code workflow. By wrapping the local Codex CLI and application server, it allows developers to perform code reviews, task delegation, and background job management without leaving the Claude Code environment. The core advantage of this architecture lies in reusing the user's existing Codex configuration, authentication state, and environment settings, ensuring consistency in the toolchain and providing various advanced interaction modes, including adversarial reviews and task rescue.

// key highlights

01
Provides standard code review functionality, supporting read-only analysis of current changes or specific branches.
02
Supports adversarial review mode, stress-testing code reliability by questioning implementation plans and design decisions.
03
Features task delegation, allowing bug investigation or repair tasks to be handed off to Codex sub-agents.
04
Supports background job management, handling time-consuming tasks through status queries, result viewing, and task cancellation.
05
Integrates an optional review gating mechanism that automatically triggers a Codex review after a Claude response to intercept potential issues.
06
Fully compatible with existing Codex configuration files, supporting customization of models and inference effort via a local config.toml.

// use cases

01
Perform read-only code reviews to check current changes or branch diffs
02
Conduct adversarial reviews to evaluate design decisions, risk points, and alternatives
03
Delegate specific tasks (such as fixing bugs or investigating regressions) to Codex for processing

// getting started

First, add and install the plugin via the Claude Code plugin marketplace by running /plugin marketplace add openai/codex-plugin-cc and /plugin install codex@openai-codex.
