What problem does it solve? Code reviews often miss the actual scope of changes, rely on speculation, or produce vague style complaints. This Skill enforces a disciplined review process that pins the review scope, verifies each finding in current code, and ranks defects by impact. ## Core Features & Use Cases - Scope Pinning: Determines the correct diff base from the merge-base, PR metadata, or working tree state, including staged, unstaged, and untracked files. - Evidence-Based Findings: Requires each finding to identify the trigger, affected behavior, precise location, and consequence, verified in current code before reporting. - Ranked Reporting: Separates correctness defects from validation gaps and conformance uncertainty, and explicitly reports when no findings are supported. - Use Case: Before merging a pull request, run this Skill to compare the branch against its merge-base, check callers and tests for regressions, and receive a ranked list of verified defects with file locations. ## Quick Start Review the current branch against main and report any verified defects with their locations and impact.
