Deep code simplification and refactoring preserving behavior across Python, Go, TypeScript, Rust. Targets complexity, anti-patterns, readability debt. Triggers on: "simplify this code", "refactor for clarity", "reduce complexity", "make this more readable", "tech debt cleanup", "too much nesting".
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
# Code Refiner A structured, multi-pass code refinement skill that transforms complex, verbose, or tangled code into clean, idiomatic, maintainable implementations — without changing what the code does. ## Philosophy The goal is **not** fewer lines. The goal is code that a tired engineer at 2am can read, understand, and safely modify. Every change must pass three tests: 1. **Behavioral equivalence** — identical inputs produce identical outputs, side effects, and errors 2. **Cognitive load reduction** — a reader unfamiliar with the code understands it faster after the change 3. **Maintenance leverage** — the change makes future modifications easier, not harder When clarity and brevity conflict, clarity wins. When idiom and explicitness conflict, consider the team's experience level. When DRY and locality conflict, prefer locality for code read more than modified. ## Prerequisites - **git** — used in Phase 1 for scope detection (`git diff`) when the user doesn't specify target files - **Python 3.10+** — required to run `scripts/complexity_report.py` for quantitative complexity metrics ## Workflow …

How to install
mdr add mathews-tom/armory/code-refiner@sha256:1c2970980194177dThe line at the top of this page pins the label v1.1.1, 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.
