Clean code, DRY, KISS, YAGNI, function length, abstraction level, function argument count, Boy Scout Rule, intent-revealing naming. Auto-load when writing functions, reviewing code clarity, or debating whether to abstract.
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
<!-- preload-canary: SWB-PRELOAD-PRINCIPLE-CLEAN-CODE --> # Clean Code ## Function Rules | Rule | Guideline | |------|-----------| | **Function length** | Prefer under 20 lines. Extract when doing two things. | | **Naming** | Name reveals intent. No abbreviations except universal ones (ctx, err, id). | | **Abstraction level** | One level per function. Don't mix SQL strings with business logic. | | **Comments** | Explain WHY, not WHAT. If code needs WHAT comments, rename or extract. See Comment discipline. | | **Error handling** | Handle at the appropriate layer. Don't swallow errors silently. | | **Argument count** | 0 is ideal; 1 is common; 2 is acceptable; 3+ is suspicious. A boolean flag argument is a hidden second function — split it. | | **Command-Query Separation** | A function either changes state or returns a value — not both. | ## Comment discipline *A comment is a cost paid on every future read — spend the budget on WHY, not WHAT.* Doc-comment styles, named so authoring and review flows share one term set: | Style | Language | Soft cap | |-------|----------|----------| | Inline (`//`, `#`) | any | ≤2 lines | | godoc | Go | ~4 lines | | javadoc | Java | ~10 lines | …

How to install
mdr add lugassawan/swe-workbench/principle-clean-code@sha256:05814069e7abe509The line at the top of this page pins the label git:20260924.21f932a, 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.
