What problem does it solve? Pre-PR code changes often ship with undetected antipatterns, coverage gaps, and regression risks because a single review pass misses half the picture. This Skill runs two independent staff-level reviews — one Engineering Lead pass and one QA Lead pass — over a defined change scope, then synthesizes both critiques into a single ranked, actionable analysis.md report. ## Core Features & Use Cases - Two-track independent review: An Engineering Lead pass covers antipatterns, hot paths, consistency with AGENTS.md conventions, dead code, and design issues; a QA Lead pass covers test coverage, edge cases, regression risk, and verifiability. The passes never see each other's output until synthesis. - Flexible scope resolution: Review the working tree, last commit, commits since push, a commit range, a file list, or the commits recorded in a sibling plan.md's progress log. - Synthesized severity-ranked report: Findings are deduplicated, ranked Blocker through Nit, cited with file paths and line ranges, and each ends with a concrete recommendation. - Use Case: After dev-do produces a few commits in scratch/0423-02/, run the review with slot number 2 to get a read-only quality gate report before opening the PR. ## Quick Start Review the commits from slot 2 and write the synthesized engineering and QA findings to its analysis.md file.
