What problem does it solve? Recent code changes often accumulate formatting inconsistencies, lint violations, dead code, and AI-generated slop that degrade maintainability. This Skill runs a layered cleanup pass over your recent changes while strictly preserving behavior and public APIs. ## Core Features & Use Cases - Deterministic formatting and linting: Runs the project's existing formatters and linters (Biome, Prettier, rustfmt, gofmt, and more) through the tidy tool, then applies structural rule packs, all scoped to your recent diff. - Agent-level cleanup: Applies a deletion ladder and four review lenses (reuse, quality, efficiency, altitude) to remove dead code, duplication, over-defensive checks, and needless complexity, with findings tiered by risk (SAFE, CAREFUL, RISKY). - Use Case: After finishing a feature branch, ask the agent to tidy your changes. It formats and lints the modified files, removes unused imports and dead helpers, flags risky structural issues for review, and reports test and typecheck results. ## Quick Start Tidy up my recent uncommitted changes, formatting and linting them and removing any dead code without changing behavior.
