openai/codex-plugin-cc
OpenAI's plugin lets you drive Codex from inside Claude Code—slash commands for code review, adversarial critique, and delegating or handing off tasks to Codex background jobs. ~629 stars today.
**The gist** `openai/codex-plugin-cc` adds Codex to **Claude Code** via slash commands: `/codex:review` and `/codex:adversarial-review` for read-only code review, plus `/codex:rescue`, `/codex:transfer`, `/codex:status`, `/codex:result`, and `/codex:cancel` for delegating and tracking background Codex jobs. It wraps the global `codex` binary and reuses your existing auth, `.codex/config.toml`, and local checkout.
**Why it matters** If you run Claude Code as your primary agent, this gives you a second model for cross-review or handoff without leaving the session—delegate an investigation to Codex, get an adversarial critique that challenges your design, or transfer a session into a persistent Codex thread.

It's a thin wrapper over the local Codex binary, so anything Codex can't do locally, the plugin can't either.
