What problem does it solve? Codebases accumulate dead code, redundant abstractions, and hand-rolled utilities that duplicate standard library features. This Skill scans the whole repository and reports exactly what to delete, simplify, or replace, ranked by impact. ## Core Features & Use Cases - Whole-Repo Over-Engineering Scan: Hunts for dead code, single-implementation interfaces, one-product factories, delegating wrappers, unused config flags, and hand-rolled stdlib equivalents. - Tagged Findings: Classifies each finding as delete, stdlib, native, yagni, or shrink, with a concrete replacement named for each. - Ranked One-Shot Report: Outputs one line per finding ordered biggest cut first, ending with a net estimate of removable lines and dependencies. - Use Case: Before a refactor sprint, ask for an audit of your repo to identify which dependencies can be dropped in favor of platform-native features and which abstraction layers have only one caller. ## Quick Start Ask the assistant to audit this codebase for over-engineering and list what can be deleted or replaced with standard library equivalents.
