What problem does it solve? After implementing a feature, diffs often accumulate over-engineering: single-use abstractions, misleading type assertions, dead branches, and inefficient patterns. This Skill reviews only the changed code, classifies each issue, and applies minimal targeted fixes so reviews stay focused and cognitive load drops. ## Core Features & Use Cases - Diff-scoped review: Analyzes only recent changes via git diff, classifying signals like single-use abstractions, any casts, async functions without await, and barrel export bloat. - Efficiency checks: Detects N+1 queries, sync calls in async contexts, redundant fetches, over-fetching, and unnecessary React re-renders. - Cut-format over-engineering report: When asked what to delete, produces a scannable one-line-per-finding report with tags like delete:, stdlib:, yagni:, and a net-lines metric, at lite, full, or ultra intensity. - Use Case: After finishing a TypeScript feature, ask for a simplify pass to inline a helper used once, unwrap a single-promise Promise.all, and batch a per-item database loop before opening the PR. ## Quick Start Ask the assistant to simplify the code in my current git diff and fix any over-engineering it finds.
