description Overview

Extract Field

When several related fields are declared sequentially within a class, this refactoring groups them together and often suggests encapsulating them into a dedicated Value Object (VO) or Data Transfer Object (DTO). This improves the class's cohesion by logically grouping related data members, making the class definition cleaner and more semantic.

Extract Constant

This tool identifies literal values (like '3.14159' or 'MAX_RETRIES') used repeatedly throughout the code. It extracts these 'magic numbers' into a dedicated, named constant field or variable. This centralizes configuration, making global changes trivial and preventing inconsistencies across the codebase.
