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.

Extract Interface from Class

A specialized version of Extract Type, this tool specifically targets extracting the *public contract* of a class into an interface. It analyzes which methods are called externally versus which are internal implementation details, guiding the developer to define the minimal necessary public API contract. This is the safest way to prepare a class for dependency inversion.
