What problem does it solve?

This Skill provides a structured approach to improving code design and readability without altering external behavior. It helps developers systematically tackle technical debt, making large codebases easier to understand, maintain, and extend.

Core Features & Use Cases

• Composing Methods: Patterns like "Extract Function" and "Replace Temp with Query" to simplify complex logic and give semantic names to code fragments.
• Moving Features: Guidance on "Move Function" and "Replace Loop with Pipeline" to improve module cohesion and reduce coupling between components.
• Simplifying Conditionals: Techniques like "Decompose Conditional" and "Replace Nested Conditional with Guard Clauses" to reduce complexity and improve the clarity of decision-making logic.
• Use Case: A developer encounters a monolithic function with deeply nested conditionals. They can use this skill to apply "Extract Function" to break it down and "Replace Nested Conditional with Guard Clauses" to flatten the logic, making the function much more readable and testable.

Quick Start

Refactor the 'calculateOrderTotal' function in 'src/services/order.ts' using the "Extract Function" pattern to improve readability.
