OpenAI's Codex CLI wrapped into a skill for specialized code reviews using GPT-5.2-Codex, which apparently hits 88% detection on bugs and security flaws according to LiveCodeBench. The setup is straightforward if you have Node 22 and either a ChatGPT subscription or API key. You can run it interactively with `/review` in the TUI or go headless for CI/CD with `--full-auto` and JSON schemas. The GitHub integration is clean, just drop `@codex review` in a PR comment or wire up the action. Honestly, this feels most useful when you want a second opinion before opening a PR or need automated reviews in pipelines without setting up complex linting infrastructure.
