# Adversarial review skill Generates review findings from scratch. This is the pre-merge self-review counterpart to `pr-review` (which triages *existing* comments). Its whole reason to exist is to catch the defects a diff-scoped bot structurally can't: whole-system, failure-mode, and consistency bugs. The method's power comes from **independent lenses** and **adversarial verification** — preserve both. ## Input `$SCOPE` — free text describing **what to review** and, optionally, **what to focus on**. The agent interprets it; it is not a rigid parser. Accepted forms: - **A file or directory** — `app/services/payments.py`, `app/api/`. - **A PR number** — `PR #123` or `123`. Pull the diff and the changed files. - **A diff / "the current change"** — the default when nothing is given: the uncommitted work, or if that's empty, the branch vs its merge base. - **A topic or subsystem** — `the upstream fetch retry path`, `cache invalidation`. First **resolve which files it means** (grep/explore), then review those; a topic is inferred scope, so it's less precise than naming files. - **Any of the above plus focus instructions** — `app/services/orders.py — focus on transaction/rollback semantics`, or `the checkout endpoint; I care most about the concurrency angle, skip style nits`. ### Delta mode: reviewing changes made *since* a previous review When this skill has already reviewed the change and work continued afterwards (fixes for the findings, a new requirement, a follo
