This skill is specialised: git-aware, uses a tuned review prompt, saves structured output. ## When to Use - After a meaningful change, before committing or shipping - Before opening a PR, to self-review with an independent reviewer - When something feels off but you can't articulate what - Periodic whole-app reviews for projects in active development - When the user explicitly asks for an "independent" or "second opinion" review **Do NOT use** for: - Trivial changes (typos, one-line fixes) - Research questions or architecture discussions — use `brains-trust` instead - Auto-fixing issues — this is advisory only ## Preflight 1. Confirm Codex CLI is installed: ```bash which codex ``` If missing: tell the user to install it (`brew install codex` on macOS, or see https://github.com/openai/codex) and stop. Do not continue. 2.

If that happens, instruct the user to run `codex login` and stop. ## Determine scope Pick the scope flag based on what the user asked for: | User intent | Flag | |---|---| | "codex review" / "review the app" / "full review" / default | no flag (reviews whole app ...
