Applies principles from Robert C. Martin's 'Clean Code'. Use this skill when writing, reviewing, or refactoring code to ensure high quality, readability, and maintainability. Covers naming, functions, comments, error handling, and class design.
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.

# Clean Code Skill
This skill embodies the principles of "Clean Code" by Robert C. Martin (Uncle Bob). Use it to transform "code that works" into "code that is clean."
## 🧠 Core Philosophy
> "Code is clean if it can be read, and enhanced by a developer other than its original author." — Grady Booch
## When to Use
Use this skill when:
- **Writing new code**: To ensure high quality from the start.
- **Reviewing Pull Requests**: To provide constructive, principle-based feedback.
- **Refactoring legacy code**: To identify and remove code smells.
- **Improving team standards**: To align on industry-standard best practices.
## 1. Meaningful Names
- **Use Intention-Revealing Names**: `elapsedTimeInDays` instead of `d`.
- **Avoid Disinformation**: Don't use `accountList` if it's actually a `Map`.
- **Make Meaningful Distinctions**: Avoid `ProductData` vs `ProductInfo`.
- **Use Pronounceable/Searchable Names**: Avoid `genymdhms`.
- **Class Names**: Use nouns (`Customer`, `WikiPage`). Avoid `Manager`, `Data`.
- **Method Names**: Use verbs (`postPayment`, `deletePage`).
## 2. Functions
- **Small!**: Functions should be shorter than you think.

The line at the top of this page pins the label git:20261001.4ae104e, 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.
