Ponytail Review

When your codebase feels heavier than it should be, this runs surgical strikes against over-engineering. It finds hand-rolled validators that could be one-liners, dependencies imported for single calls, abstract classes with one implementation, and dead flexibility nobody asked for. Output is brutally compact: one line per finding with the location, what to delete, and what replaces it. Ends with a net line count you could remove. It deliberately ignores correctness and security, those need separate review. Use it when you suspect the diff made things more complex instead of simpler, or when "we can delete this" sounds more exciting than "we can add this."
