What problem does it solve? Codebases accumulate unnecessary complexity: reinvented standard library functions, unneeded dependencies, speculative abstractions, and dead flexibility. This Skill performs a review pass focused exclusively on finding what to cut, complementing correctness-focused reviews. ## Core Features & Use Cases - Over-Engineering Detection: Flags dead code, hand-rolled stdlib equivalents, redundant dependencies, single-implementation abstractions, and verbose logic. - One-Line Findings: Each finding follows a strict format with location, tag (delete, stdlib, native, yagni, shrink), what to cut, and what replaces it. - Net-Line Scoring: Ends every review with a single metric estimating how many lines can be removed, or reports "Lean already. Ship." when nothing can be cut. - Use Case: After writing a pull request, ask for an over-engineering review to discover that a 27-line validator class can be replaced by a one-line check, or that moment.js can be swapped for Intl.DateTimeFormat. ## Quick Start Ask the assistant to review this diff for over-engineering and tell me what can be deleted or simplified.
