review-agent
Codex's bundled skill for reviewing changes — the current in-box option, no install needed.
What it actually does
- The in-box option for reviewing changes in Codex — bundled, no install step.
When to use it — and when not to
Use it when
- You want a code review inside Codex without installing anything first.
Agent compatibility
- Codex
Confirmed means the skill’s own source or vendor states it works with that agent. Portable means it only reaches that agent through the shared SKILL.md format and a directory convention — real, but a weaker claim. An agent with no entry here isn’t known to be unsupported; it simply isn’t documented either way, so nothing is claimed. Full model on Agent Skills Compatibility.
