description Overview

Extract Constant

This tool identifies literal values (like '3.14159' or 'MAX_RETRIES') used repeatedly throughout the code. It extracts these 'magic numbers' into a dedicated, named constant field or variable. This centralizes configuration, making global changes trivial and preventing inconsistencies across the codebase.

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.
