Code review focused exclusively on over-engineering. Finds what to delete: reinvented standard library, unneeded dependencies, speculative abstractions, dead flexibility. One line per finding: location, what to cut, what replaces it. Use when the user says "review for over-engineering", "what can we delete", "is this over-engineered", "simplify review", or invokes /ponytail-review. Complements correctness-focused review, this one only hunts complexity.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
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.` …

How to install
mdr add dmae97/omk/ponytail-review@sha256:75c4cec9f8c1ec50The line at the top of this page pins the label git:20260704.16a0c60, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
