Ponytail Audit

Runs a whole-repo scan for over-engineering and bloat, tagging dependencies you can replace with stdlib, abstractions with single implementations, hand-rolled utilities the platform ships natively, and dead configuration nobody touches. Output is a ranked one-liner list of what to cut, biggest savings first, with line and dependency counts at the end. It's read-only, applies nothing, and explicitly ignores correctness or performance issues. Use it when you inherit a codebase that feels heavy or when you're pretty sure there's stuff to delete but don't know where to start. Think of it as Marie Kondo for code, except it actually tells you the specific drawer to open.
