That was my first real session with OpenAI’s codex-plugin-cc — an official plugin, published March 30, 2026, that puts Codex directly inside Claude Code. Not a community hack. Not a bash script wrapper. OpenAI built this, packaged it as a plugin, and shipped it through Claude Code’s plugin marketplace.
Every tech outlet has already covered what it is. This article covers what to actually do with it.
What This Is (And What It Is Not)
The plugin gives you six slash commands inside Claude Code:
/codex:review — standard read-only code review of your current changes
/codex:adversarial-review — steerable review that challenges design decisions
/codex:rescue — delegates a task entirely to Codex (bug investigation, fixes, parallel work)
/codex:status, /codex:result, /codex:cancel — job management for background tasks
It also includes an optional review gate — a Stop hook that intercepts Claude’s output and runs a Codex review before Claude can finish. More on that in Use Case 3.
