Use when working in an unfamiliar language or matching an unfamiliar codebase style. Derives a style guide by sampling.

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

# Language Style Sampling — Derive Guide From Sample

Capability: produce checkable style rules for any project/language by sampling authoritative sources, not LLM prior.

## When

Before authoring new skill or CONTRIBUTING style section for language/project whose CONTRIBUTING is sparse, or onboarding new repo.

## Method

1. Discover authoritative sources ordered:
   - Language official style: Effective Go, PEP8 / Google Python Style, Rust API Guidelines, Mozilla JS Guide, clang-format doc, project's own CONTRIBUTING/HACKING.
   - Sample 3-5 real files from canon (stdlib, well-maintained cited repo), not random snippets. Paste paths.

2. Extract checkable rules — 5 categories:
   - Naming: files, functions, predicate bools should_/is_/try_, constants, packages.
   - Comment density: WHY not WHAT, where doc lives definition vs header, subtle logic MUST WHY.
   - Error handling: return vs exception, wrapping, logging level, sentinel vs typed.
   - Function length signal: typical ≤20 logical, hard 40 — what prompts extraction and how to name helper by intent theme.
   - Trailing hygiene: public links only, banned class private paths, subject style if conventional commits enforced.

How to install

The exact contents, by fingerprint
mdr add rikvanriel/code-hygiene/language-style-sampling@sha256:ce9586e0ee44752f

The line at the top of this page pins the label v1.0.0, 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.
