Agent skills for code review in Codex

1,365 agent skills for code review in the catalog list Codex as a supported host. These are the 15 that rank highest, ordered by adoption, freshness and documentation. ai-coding-agent-guardrails, caveman-review and code-review lead the list. Codex reads them from .agents/skills/<name>/SKILL.md in the project, or ~/.agents/skills/<name>/ for every project. A skill is a folder with a SKILL.md file; Codex loads it when a task matches its description. Every listing links to its source and shows a freshness grade.

How to install in Codex

$skill-installer <name>   (inside a Codex session)

Where it goes: .agents/skills/<name>/SKILL.md in the project, or ~/.agents/skills/<name>/ for every project.

Codex's docs also describe creating a folder with a SKILL.md by hand. They list no codex skills command. Restart Codex if a new skill does not appear. Any folder with a SKILL.md works: copy it in by hand if you prefer.

Each listing page has the exact command for that listing.
