description Overview

Replace Type Parameter

When working with generic containers (like `List` or custom generic types), this refactoring allows you to systematically replace the type argument `T` with a concrete type or another generic type across all usages. It is vital for maintaining type safety when evolving generic APIs, ensuring that all consumers of the generic structure are updated correctly.

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.
