Top Code Quality & Review Skills for Codex
For code review in Codex CLI, install Trail of Bits' security skills and Anthropic's debug and tech-debt skills — Codex runs in the terminal with real repo access, which is exactly the setting where a severity-tagged review pass beats an inline suggestion. superpowers and tdd-skill add the before-the-code discipline if you want review pressure earlier than the diff.

FAQ
Common questions
How does Codex load a skill compared with Claude Code?
Codex adopted the SKILL.md format directly, so the same folder works, but the install path differs: Codex takes the repo-plus-path form (codex skills add github.com/owner/repo/skills/name) rather than a --skill flag. The frontmatter and the three-tier loading behaviour are the same.
How many code review skills work with Codex?
11 of the 20 skills catalogued in Code Quality & Review are verified working on Codex. The remaining 9 are either untested on this agent or depend on capabilities it does not provide — they are listed below rather than hidden.
How do I install a code review skill on Codex?
Each skill page carries the exact Codex command. Codex reads SKILL.md natively, so a skill folder works unchanged.
