What problem does it solve? Code review of a branch or PR often stays shallow, inconsistent, or swayed by the author's framing. This Skill runs a structured panel review of a pinned diff, dispatching four independent judge agents (Design, Craft, Fitness, Stability) that must back every finding with evidence, then applies a mechanical gate to produce a single PASS, FAIL, or INCOMPLETE verdict. ## Core Features & Use Cases - Four specialized judges: Design checks whether the right modules exist, Craft checks code quality rules and smells, Fitness challenges whether the change should exist at all, and Stability traces the blast radius of altered behavior. - Evidence-gated findings: Every blocking finding must cite a rubric rule tagged as a presumptive blocker and meet its evidence bar (file:line citations, module tables, premise tables, traced dependents), so verdicts rest on proof rather than opinion. - Pinned, reproducible scope: The review range is pinned to explicit base/head SHAs or a PR's merge base, with a fact-only census (stated purpose, premises, siblings, trajectory, house record, diff stats) built before any judging. - Use Case: Before merging a large feature PR, ask for a deep review of the PR; the Skill gathers the diff and context, runs the four judges in parallel, and returns a decision brief listing blocking findings, unchecked obligations, and per-seat summaries. ## Quick Start Run a deep review of PR number 123 with all four judges and give me the decision brief.
