Clean Code principles (DRY, KISS, YAGNI), naming, function design and readability. Use when code is hard to read, with long methods, unclear names, duplication or deep nesting. For how responsibilities are split across classes and which way dependencies point, use solid-principles instead.

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

# Clean Code Skill

Write readable, maintainable code following Clean Code principles.

## When to Use
- User says "clean this code" / "refactor" / "improve readability"
- Code review focusing on maintainability
- Reducing complexity
- Improving naming

---

## Core Principles

| Principle | Meaning | Violation Sign |
|-----------|---------|----------------|
| **DRY** | Don't Repeat Yourself | Copy-pasted code blocks |
| **KISS** | Keep It Simple, Stupid | Over-engineered solutions |
| **YAGNI** | You Aren't Gonna Need It | Features "just in case" |

---

## DRY - Don't Repeat Yourself

> "Every piece of knowledge must have a single, unambiguous representation in the system."

### Violation

```java
// ❌ BAD: Same validation logic repeated
public class UserController {

    public void createUser(UserRequest request) {
        if (request.getEmail() == null || request.getEmail().isBlank()) {
            throw new ValidationException("Email is required");
        }
        if (!request.getEmail().contains("@")) {
            throw new ValidationException("Invalid email format");
        }
        // ... create user
    }

    public void updateUser(UserRequest request) {

How to install

The exact contents, by fingerprint

mdr add decebals/claude-code-java/clean-code@sha256:d39944c25c2ca957

The line at the top of this page pins the label git:20260828.d70ab4f, 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.
