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 only the fixes worth applying. ## Core Features & Use Cases - Parallel 4-Agent Review: Launches reuse, quality, efficiency, and altitude reviewers concurrently via delegate_task batch mode, each searching the full codebase for evidence. - Risk-Tiered Application: Auto-applies SAFE fixes, verifies CAREFUL fixes with tests, and flags RISKY changes (public API renames, N+1 restructuring) for human review. - Flexible Scoping: Supports focus filters (reuse, quality, efficiency, altitude), dry-run mode, and diff scoping (staged, last commit, branch, specific files). - Use Case: After finishing a feature branch, ask to simplify your changes; the Skill reviews the diff, removes duplicated logic and dead code, flattens nested conditionals, and reports deeper infrastructure fixes worth a follow-up task. ## Quick Start Ask the agent to simplify my recent changes and apply the safe fixes after running the project tests.
