Scans the entire codebase for over-engineering: dead code, stdlib replacements, native alternatives, YAGNI abstractions, and bloat. Produces a ranked list of what to delete or simplify.

ponytail-review, repo-wide. Scan the whole tree instead of a diff. Rank findings biggest cut first.
Same as ponytail-review:
delete: dead code, unused flexibility, speculative feature. Replacement: nothing.stdlib: hand-rolled thing the standard library ships. Name the function.native: dependency or code doing what the platform already does. Name the feature.yagni: abstraction with one implementation, config nobody sets, layer with one caller.shrink: same logic, fewer lines. Show the shorter form.Deps the stdlib or platform already ships, single-implementation interfaces, factories with one product, wrappers that only delegate, files exporting one thing, dead flags and config, hand-rolled stdlib.
One line per finding, ranked: <tag> <what to cut>. <replacement>. [path].
End with net: -<N> lines, -<M> deps possible. Nothing to cut: Lean already. Ship.
Complexity only, correctness bugs, security holes, and performance go to a normal review pass. Lists findings, applies nothing. One-shot. "stop ponytail-audit" or "normal mode" to revert.

Whole-repo audit for over-engineering: finds dead code, unnecessary abstractions, stdlib-replaceable dependencies. Outputs ranked findings and net line/dep savings.
Reviews diffs for over-engineering, suggesting deletions, stdlib replacements, and simplifications. Best result: diff gets shorter.
Audits codebases to remove dead code, AI slop, and DRY/SOLID violations, restructuring toward simplest correct implementation. Detects stack and applies idiomatic patterns.
