Structured pull-request review against engineering-standards, the active stack pack, security, NFR impact, and test sufficiency. Produces a severity-tagged review report (blocker / major / minor / nit) with diff-anchored locations and concrete fix suggestions. Used by the Code Reviewer agent and as a pre-merge gate. Distinct from Security Reviewer (different remit, different tool scope). Use on every PR; pushy trigger because skipping reviews is the single most common cause of accumulated tech debt.
