What problem does it solve? Before formal code review, diffs often contain duplication, rough edges, and avoidable inefficiency that generate unnecessary reviewer comments. This Skill runs a pre-review cleanup pass that finds and fixes worthwhile issues without changing behavior. ## Core Features & Use Cases - Three Parallel Review Agents: Spawns read-only subagents covering code reuse, code quality, and efficiency, each guided by a dedicated prompt template in the references directory. - Behavior-Preserving Fixes: The main agent aggregates findings, deduplicates them, applies only safe cleanups, and skips false positives. - Explicit Verification: Runs the narrowest meaningful tests or lint/build checks after edits and reports residual risk when no verification exists. - Use Case: After implementing a feature spanning several files, run this cleanup pass before sending the diff to a formal code-reviewer to reduce avoidable review comments. ## Quick Start Ask the assistant to run the simplify cleanup pass on the current git diff before formal code review.
