description Overview

Replace Type with Generic

When a piece of code handles multiple, but related, types (e.g., processing `List` and `List`), this refactoring allows you to generalize the type parameter, replacing the specific type with a generic placeholder `T`. This maximizes code reuse by abstracting the specific type while retaining type safety.

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.
