Introducing the Codex Plugin for Claude Code

·2026.03.31 09:00

Key point

A plugin has been released that lets you use Codex to perform code reviews and tasks within the Claude Code workflow.

Details

For Claude Code users, the Codex plugin lets you integrate Codex's powerful capabilities while keeping your existing workflow.

The plugin offers three core features.

  • Codex review: A general, read-only code review
  • Adversarial review: A challenging review that critically examines and questions the implementation. Useful for tasks where hidden risks may lurk, such as migrations, authentication changes, or infrastructure scripts.
  • Rescue: A feature that hands the task directly to Codex when the workflow stalls

The main commands are /codex:review, /codex:adversarial-review, and /codex:rescue, and /codex:status, /codex:result, and /codex:cancel can be used to manage background tasks.

The plugin operates via the local Codex CLI and Codex app server, so it runs lightly without requiring a separate runtime. Additionally, the /codex:setup --enable-review-gate option can be used to prevent Claude Code from exiting until the Codex review is complete.
