What problem does it solve? Codebases accumulate unnecessary complexity over time: hand-rolled reimplementations of standard library functions, duplicate dependencies, speculative abstractions with a single implementation, and dead configuration. This Skill performs a focused review that finds exactly what to delete and what replaces it, producing a one-line-per-finding report. ## Core Features & Use Cases - Complexity-Only Audit: Hunts reinvented stdlib functionality, unneeded dependencies, speculative abstractions, and dead flexibility while explicitly excluding correctness, security, and performance concerns. - Tagged Findings: Each finding is tagged (delete, stdlib, native, yagni, shrink, library, dup-dep, convention) with the location, what to cut, and the concrete replacement. - Scoped or Whole-Tree Review: Scans the entire codebase by default, or limits the review to a named scope such as a diff, staged changes, a PR, specific files, or a module. - Use Case: Before a release, ask for an over-engineering audit of your repository and receive a ranked list like Cargo.toml:L18: dup-dep: reqwest and ureq both present. Keep reqwest. ending with a net line and dependency reduction estimate. ## Quick Start Review this codebase for over-engineering and tell me what can be deleted or replaced with standard library or existing dependencies.
