What problem does it solve? Pre-PR code review often misses issues because a single reviewer cannot simultaneously hold an engineering-quality lens and a QA/test-coverage lens. This Skill runs two independent review passes over a defined change scope and merges them into one ranked, actionable analysis report. ## Core Features & Use Cases - Two-track review: A staff-level Engineering Lead pass (antipatterns, hot paths, consistency, dead code, provenance via git history) and a QA Lead pass (coverage, edge cases, regression risk, verifiability) run independently, then a synthesizer deduplicates, ranks by severity, and scores confidence 0-100. - Flexible scope resolution: Review the working tree, last commit, unpushed commits, a commit range, a file list, or the commits recorded in a sibling plan.md slot. - Read-only guarantee: Never modifies source, never commits, never pushes; the only file written is analysis.md under a gitignored scratch/ directory. - Use Case: After finishing a feature branch, run the review on your unpushed commits to get a severity-ranked findings report with file/line citations and concrete recommendations before opening the PR. ## Quick Start Review my unpushed commits with the dev-review skill and write the findings to slot 2.
