What problem does it solve? Code reviews are inconsistent: reviewers miss security holes, breaking contract changes, and failing validation gates, and feedback arrives without clear severity or a merge verdict. This Skill standardizes the review of any diff, branch, or pull request against correctness, security, breaking-change, and quality rules, producing actionable findings and a mechanical approve/request-changes verdict. ## Core Features & Use Cases - Mandatory validation gate: Runs every configured validation command in order and reports per-command PASS/FAIL/NOT RUN results; any failure is a blocker finding. - Severity-ranked findings: Applies a built-in staff-engineer checklist plus repo-local checklists (CODE_REVIEW.md, BACKWARD_COMPATIBILITY.md, product-brief.md) and reports blocker/major/minor/nit findings with file, line, and concrete fixes. - Contract and security gates: Flags breaking changes to APIs, routes, events, CLI flags, and DB schemas without deprecation paths, plus missing permission checks, data-scoping leaks, and migration anomalies. - Use Case: Point it at PR #42 and receive a structured review report with a validation-gate table, severity-grouped findings, breaking-change consequences, test-coverage gaps, and a final verdict that callers like om-auto-review-pr use to drive labels and autofix loops. ## Quick Start Ask the agent to review the current branch's diff against the base branch and produce a severity-ranked review report with a merge verdict.
