To refactor code for readability without altering behavior, you can rename unclear variables, extract long methods into focused functions, and remove dead code. This behavior-preserving process improves code maintainability and structure.

The best way to remove magic numbers and dead code is through a structured refactoring workflow that surveys, plans, applies, verifies, and presents changes. This standardizes patterns and breaks down complex logic into smaller, manageable parts.

Code review integrates with refactoring by operating across defined scope tiers like Focused, Module, and Project-wide. This workflow evaluates code quality comprehensively, ensuring maintainability improvements are verified before presentation.

Yes, you can use automated refactoring for module-level code structure improvements. It operates within defined scope tiers, allowing you to extract long methods and rename functions across an entire module without breaking existing behavior.

You should extract methods from a long function during code review when the logic becomes hard to follow. Breaking it down into smaller, well-named parts makes the code easier to grasp, modify, and maintain over time.
