description Overview

Change Parameter Type

This refactoring changes the expected type of an argument in a method signature (e.g., from `String` to `UUID`). The IDE automatically updates the method body to handle the conversion or throws errors at all call sites that pass the old, incompatible type, forcing the developer to explicitly handle the necessary type conversion logic.

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.
