ponytail-audit

What problem does it solve? Codebases accumulate dead code, speculative abstractions, and hand-rolled utilities that duplicate the standard library. This Skill scans the whole repository and produces a ranked list of what to delete, simplify, or replace with stdlib or native equivalents. ## Core Features & Use Cases - Whole-repo over-engineering audit: Scans the entire tree instead of a diff and ranks findings biggest cut first. - Tagged findings: Classifies each finding as delete, stdlib, native, yagni, or shrink, with a concrete replacement named. - Net impact summary: Ends with an estimate of lines and dependencies removable, or reports the codebase is already lean. - Use Case: Before a major refactor, run the audit to find single-implementation interfaces, one-product factories, dead config flags, and dependencies the platform already provides. ## Quick Start Ask the assistant to audit this codebase for over-engineering and list what can be deleted or replaced with stdlib equivalents.
