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 produces a ranked list of what to delete, simplify, or replace, so you can reduce maintenance burden without guessing where the bloat lives. ## Core Features & Use Cases - Whole-Repo Over-Engineering Scan: Unlike a diff-based review, it audits the entire tree for dead code, unused flexibility, and speculative features. - Tagged Findings: Each finding is labeled 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 major refactor, run the audit to discover that a custom retry wrapper duplicates a platform feature and three single-implementation interfaces can be collapsed, cutting hundreds of lines. ## Quick Start Ask the AI to audit this codebase for over-engineering and list what can be deleted or replaced with standard library equivalents.
