Best for

Developers who use Claude Code and Codex concurrently and want to reduce manual switching between the two environments.
Users needing to run design pressure-tests or obtain secondary code reviews without leaving their current CLI workflow.

Key capabilities

Provides a read-only code review of uncommitted changes or a specific branch by delegating to Codex.
Questions the chosen implementation and design to pressure-test assumptions, tradeoffs, and failure modes.
Delegates tasks to Codex to investigate bugs, try fixes, or take a faster pass with a smaller model.
Creates a persistent Codex thread from the current Claude Code session to continue the same context directly in Codex.
Shows running and recent Codex jobs, retrieves final stored output, and cancels active background jobs.
Uses a Stop hook to run a targeted Codex review based on Claude's response and blocks the stop if issues are found.
Checks whether Codex is installed and authenticated, and can offer to install Codex if missing.

Limitations and risks

Requires a ChatGPT subscription or an OpenAI API key to function.
The session transfer source must be under ~/.claude/projects, and older Codex versions must be upgraded for it to work.
Enabling the review gate can create a long-running Claude/Codex loop and may drain usage limits quickly.

Getting started

Run /plugin marketplace add openai/codex-plugin-cc, then /plugin install codex@openai-codex, followed by /reload-plugins and /codex:setup to complete the installation.

Evidence and sources

README: Use Codex from inside Claude Code for code reviews or to delegate tasks to Codex.
README: `/codex:rescue`, `/codex:transfer`, `/codex:status`, `/codex:result`, and `/codex:cancel` to delegate work, hand off sessions, and manage background jobs
README: Runs a normal Codex review on your current work. It gives you the same quality of code review as running `/review` inside Codex directly.
README: Runs a **steerable** review that questions the chosen implementation and design.
README: take a faster or cheaper pass with a smaller model
