refactoring/composing-methods

What problem does it solve?

Long methods that blend control flow, calculations, and side effects into one unwieldy block become hard to read, test, and change. This Skill helps you name intentions clearly by isolating chunks of logic, reducing cognitive load and preventing regressions before they reach review.

Core Features & Use Cases

• Extract Method: Identify coherent subsequences and replace them with well-named helper methods, improving intent visibility in complex loops or service handlers.
• Inline Method / Variable: Remove unnecessary indirection when the method body is more obvious than its name, befriending future maintainers with simplicity.
• Advanced Refactors: Split temporary variables, replace tangled parameter assignments, or convert cluttered logic into Method Objects to keep domain services lean.
• Use Case: Apply it to a NestJS booking service that calculates fees and sends notifications to break down the method into payment, validation, and messaging helpers.

Quick Start

Ask the skill to analyze a sprawling TypeScript method, suggest extraction points, and rewrite it with descriptive helpers.
