Refactoring Guide Skill

Refactoring is the process of restructuring existing computer code—changing the factoring—without changing its external behavior.

Core Refactoring Patterns

1. Composing Methods

• Extract Method: If a method is too long or complex, turn a fragment of it into its own method.
• Inline Method: If a method body is as clear as its name, move the body into the callers and delete the method.

2. Moving Features Between Objects

• Move Method/Field: Relocate logic to the class where it most naturally belongs to reduce coupling.

3. Simplifying Expressions

• Decompose Conditional: Extract complex conditional logic into clearly named methods.
• Consolidate Conditional Expression: Merge multiple conditional checks that lead to the same result.
