Refactoring Skill

Core Principle

Refactoring changes code structure without changing behavior.

Refactoring is NOT about adding features or fixing bugs. It's about making code easier to understand, maintain, and extend. Every refactoring should be:

• Safe — Behavior remains unchanged
• Testable — Tests verify behavior preservation
• Incremental — Small steps, frequent commits
• Reversible — Can roll back if needed
