Introducing Claude Plugin for Codex
OpenAI Developer Community
May 18, 2026
Hi folks,
I use Claude and Codex both, and Codex now amazing. In Claude I’ve been using Plugin “Codex for Claude” , thanks @vb
But I was missing the save in Codex, as in my experience, especially for harness, and when you have both - use both!
So here is it (sorry, can’t add links to my posts)
https://github.com/yanchuk/claude-plugin-codex
Add the public marketplace:
codex plugin marketplace add yanchuk/claude-plugin-codex
Core commands:
$claude setup checks whether Claude Code is installed, authenticated, and supports the needed CLI features.
$claude review runs a structured read-only review of local git state.
$claude adversarial-review asks Claude to challenge a plan or diff.
$claude advise asks Claude for a quick second opinion.
$claude do gives Claude a prepared coding, exploration, verifier, scout, or synthesis task.
$claude rescue hands Claude a debugging or implementation task. It is read-only unless you pass --write.
$claude monitor polls a background Claude job and reports whether Claude is active, stale, or finished.
$claude status, $claude result, and $claude cancel manage Claude jobs.
I’ve been using it since a few days and it looks works fine - feel free to open your PRs and give some stars
