Most code reviews catch bugs in the diff. This one steps back and asks whether you should ship the diff at all. It starts by questioning intent and looking for simpler alternatives, then traces the actual runtime path end to end, not just the changed lines. Every finding comes with file-and-line evidence, a rationale, and a concrete fix. No LGTM stamps, no hedging. Trigger it with /scrutinize or whenever you need a cold read on a PR, plan, or design doc before you commit to the approach. Best used when you're close to the code and need an outsider sanity check.
