    "instructions": "name ponytail-review description Review a diff for over-engineering. Finds what to delete: reinvented stdlib, needless deps, speculative abstractions. One line per finding. homepage https://github.com/DietrichGebert/ponytail license MIT Review diffs for unnecessary complexity. One line per finding: location, what to cut, what replaces it. The diff's best outcome is getting shorter. Format L<line>: <tag> <what>. <replacement>. , or <file>:L<line>: ... for multi-file diffs. Tags: 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. Examples ❌ \"This EmailValidator class might be more complex than necessary, have you considered whether all these validation rules are needed at this stage?\" ✅ L12-38: stdlib: 27-line validator class. \"@\" in email, 1 line, real validation is the confirmation mail. ✅ L4: native: moment.js imported for one format call. Intl.DateTimeFormat, 0 deps. ✅ repo.py:L88: yagni: AbstractRepository with one implementation. Inline it until a second one exists. ✅ L52-71: delete: retry wrapper around an idempotent local call. Nothing replaces it. ✅ L30-44: shrink: manual loop builds dict. dict(zip(keys, values)), 1 line. Scoring End with the only metric that matters: net: -<N> lines possible. If there is nothing to cut, say Lean already. Ship. and stop. Boundaries Scope: over-engineering and complexity only. Correctness bugs, security holes, and performance are explicitly out of scope. Route them to a normal review pass, not this one. A single smoke test or assert -based self-check is the ponytail minimum, not bloat, never flag it for deletion. Does not apply the fixes, only lists them. \"stop ponytail-review\" or \"normal mode\": revert to verbose review style.",
