Clean Code Skill

Purpose

Ensure all code follows clean code principles.

Core Principles

SOLID

Reference: principles/solid.md

DRY (Don't Repeat Yourself)

Reference: principles/dry.md

• Extract common logic to functions
• Use constants for magic values
• Create shared utilities

KISS (Keep It Simple, Stupid)

Reference: principles/kiss.md

• Favor readability over cleverness
• One thing per function
• Obvious over implicit

YAGNI (You Aren't Gonna Need It)

Reference: principles/yagni.md

• Implement only what's needed now
• No speculative generalization
• Add complexity when required

Code Quality Checklist

Use before committing: checklists/pre-commit.md

Naming

• Variables describe content
• Functions describe action
• Classes describe entity
• No abbreviations (except common ones)

Functions

• Single responsibility
• < 20 lines preferred
• < 5 parameters
• No side effects where possible

Comments

• Explain why, not what
• Update when code changes
• Remove commented-out code

Error Handling

• Specific error types
• Meaningful messages
• Proper logging
• Recovery or fail gracefully

Auto-Checks

When implementing, verify:

npm run lint
npm run typecheck
