description Overview

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.

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.
