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/native equivalents. ## Core Features & Use Cases - Whole-Repo Scan: Unlike a diff-based review, it audits the entire tree for bloat, dead flags, unused config, and single-implementation abstractions. - Tagged Findings: Each finding is labeled delete, stdlib, native, yagni, or shrink, with a concrete replacement named. - Ranked One-Shot Report: Outputs one line per finding ordered biggest cut first, ending with a net line/dependency savings estimate. - Use Case: Before a major refactor, run the audit to identify wrappers that only delegate, factories with one product, and dependencies the platform already provides, then hand the list to your team for cleanup. ## Quick Start Ask the AI to run ponytail-audit on this repository and list what can be deleted or replaced with standard library equivalents.
