What problem does it solve? Code changes often ship with hidden defects, security holes, or contract-breaking changes that a quick glance misses. This Skill performs an evidence-based pre-merge review of pending changes, PRs, commits, or an entire codebase, and records a machine-readable verdict that can block shipping when the review fails. ## Core Features & Use Cases - Multiple input modes: Review pending git changes, a GitHub PR by number or URL, a specific commit hash, or run a full codebase scan. - Effort-scaled recall: Choose low through max effort levels that fan out independent review lenses, adversarially verify findings, and run a recall sweep for deeper coverage. - Gated verdict artifact: Every review writes a review-decision artifact (PASS, PASS_WITH_RISK, or BLOCKED) that a stage gate reads to allow or block pr/ship/deploy stages. - Fix and reply loops: Optionally auto-apply safe fixes, drive a full fix-and-re-review cycle, and post the final review back to the GitHub PR. - Use Case: Before merging a pull request that touches authentication code, run a high-effort review that checks correctness, security, and contract deltas, then posts a request-changes review on the PR with file-and-line evidence for each confirmed finding. ## Quick Start Ask the assistant to review the pending changes in the current repository at medium effort and report the verdict with the artifact path.
