What problem does it solve? Recent code changes often accumulate duplication, needless complexity, wasted work, and shallow band-aid fixes that a single broad review misses. This Skill runs four focused reviewers in parallel over your diff, aggregates their findings, and applies the fixes worth applying without drifting into bug hunting. ## Core Features & Use Cases - Parallel Four-Angle Review: Launches reuse, quality, efficiency, and altitude reviewers concurrently via batch delegation, each searching the codebase for evidence with file:line citations. - Risk-Tiered Application: Auto-applies SAFE fixes (unused imports, dead code), verifies CAREFUL refactors with tests, and flags RISKY changes (API renames, N+1 restructuring) for human decision. - Flexible Scoping: Supports focus filters (reuse, quality, efficiency, altitude), dry-run report-only mode, and diff scoping to staged changes, last commit, branch, or specific files. - Use Case: After finishing a feature branch, ask to simplify your changes; the Skill reviews the full diff, removes duplicated logic, flattens nested conditionals, and reports a deeper infrastructure fix it recommends as a follow-up. ## Quick Start Ask the assistant to simplify my recent changes and apply the safe fixes it finds.
