ponytail-review

Invoke the review on a diff and it returns one line per finding: location, what to cut, and what replaces it. Findings are tagged as delete, stdlib, native, yagni, or shrink, and the output ends with a net line-reduction score.

It finds dead code and unused flexibility (delete), hand-rolled logic the standard library ships (stdlib), dependencies duplicating platform features (native), abstractions with one implementation (yagni), and logic expressible in fewer lines (shrink).

No. Correctness bugs, security holes, and performance problems are explicitly out of scope and belong to a normal review pass. This review only hunts unnecessary complexity.

No. It only lists findings with locations and suggested replacements; it does not modify the code. You decide which cuts to apply.

Skip it when you need correctness, security, or performance analysis, since those are out of scope. It also never flags a single smoke test or assert-based self-check, which is considered the minimum, not bloat.
