Use when the user asks what could be deleted or reduced to simplify a codebase, says "simplify", "over-engineered", or wants a repo-, folder-, or file-wide audit for over-engineering — hunts dead code, reinvented stdlib, needless dependencies, and single-implementation abstractions, reports ranked cuts, applies only the picks. Not a diff review and not a bug hunt.
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
# Fuck Over-Engineering Audit the scope for over-engineering and report what to cut, ranked biggest cut first. The best outcome is a shorter codebase with the same behavior. The argument is the scope; without one, the whole tree. Read what the scope holds before judging it, and fan out subagents when it will not fit in context. ## Tags - `delete:` dead code, unused flexibility, speculative feature. Nothing replaces it. - `reuse:` hand-written code that a helper already in this codebase, or an installed dependency, already provides. Name the helper or function. - `stdlib:` hand-rolled thing the language's 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. ## Hunt …

How to install
mdr add vinta/hal-9000/fuck-over-engineering@sha256:9b3dc3a90e0404aeThe line at the top of this page pins the label git:20261020.eaa1ff3, 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.
