OpenAI's Codex Now Runs Inside Claude Code via Plugin

Developers can invoke Codex review, adversarial review, and rescue commands directly from Anthropic's CLI tool — a sign the tooling ecosystem is becoming genuinely model-agnostic.

OpenAI's Codex is now available as a plugin inside Anthropic's Claude Code, as @reach_vb announced. The integration adds three commands — /codex:review, /codex:adversarial-review, and /codex:rescue — giving developers the ability to run OpenAI's code analysis tools without leaving Anthropic's environment.
