Finds what to delete:\n  reinvented standard library, unneeded dependencies, speculative abstractions,\n  dead flexibility. One line per finding: location, what to cut, what replaces\n  it. Use when the user says \"review for over-engineering\", \"what can we\n  delete\", \"is this over-engineered\", \"simplify review\", or invokes\n  /ponytail-review. Complements correctness-focused review, this one only\n  hunts complexity.\n---\n\nReview diffs for unnecessary complexity. One line per finding: location, what\nto cut, what replaces it. The diff's best outcome is getting shorter.\n\n## Format\n\n`L<line>: <tag> <what>. <replacement>.`, or `<file>:L<line>: ...` for\nmulti-file diffs.\n\nTags:\n\n- `delete:` dead code, unused flexibility, speculative feature. Replacement: nothing.\n- `stdlib:` hand-rolled thing the standard library ships. Name the function.\n- `native:` dependency or code doing what the platform already does. Name the feature.\n- `yagni:` abstraction with one implementation, config nobody sets, layer with one caller.\n- `shrink:` same logic, fewer lines. Show the shorter form.\n\n## Examples\n\n❌ \"This EmailValidator class might be more complex than necessary, have you\nconsidered whether all these validation rules are needed at this stage?\"\n\n✅ `L12-38: stdlib: 27-line validator class. \"@\" in email, 1 line, real validation is the confirmation mail.`\n\n✅ `L4: native: moment.js imported for one format call. Intl.DateTimeFormat, 0 deps.`\n\n✅ `repo.py:L88: yagni: AbstractRepository with one implementation. Inline it until a second one exists.`\n\n✅ `L52-71: delete: retry wrapper around an idempotent local call. Nothing replaces it.`\n\n✅ `L30-44: shrink: manual loop builds dict. dict(zip(keys, values)), 1 line.`\n\n## Scoring\n\nEnd with the only metric that matters: `net: -<N> lines possible.`\n\nIf there is nothing to cut, say `Lean already. Ship.` and stop.\n\n## Boundaries\n\nScope: over-engineering and complexity only. Correctness bugs, security holes,\nand performance are explicitly out of scope. Route them to a normal review\npass, not this one. A single smoke test or `assert`-based\nself-check is the ponytail minimum, not bloat, never flag it for deletion.\nDoes not apply the fixes, only lists them.\n\"stop ponytail-review\" or \"normal mode\": revert to verbose review style.\n","tagline":"Code review focused exclusively on over-engineering.
