description Overview

Replace Type with Generic

When a piece of code handles multiple, but related, types (e.g., processing `List` and `List`), this refactoring allows you to generalize the type parameter, replacing the specific type with a generic placeholder `T`. This maximizes code reuse by abstracting the specific type while retaining type safety.

Change Signature

When an API contract must changesuch as adding a required parameter, changing a return type, or renaming an argumentthis tool manages the ripple effect. It updates every single call site that uses the method, prompting the developer to handle the new signature, thereby managing backward compatibility gracefully across the codebase.
