What problem does it solve?

This Skill helps you identify and implement Value Objects, a core Domain-Driven Design pattern, to encapsulate domain concepts, reduce primitive obsession, and improve code clarity and robustness.

Core Features & Use Cases

  • Identify Opportunities: Detects situations ripe for Value Object implementation, such as primitive clusters, scattered validation, or hidden domain concepts.
  • Guided Implementation: Provides a structured workflow for designing and implementing Value Objects, emphasizing intention-revealing interfaces and side-effect-free behavior.
  • Use Case: Refactor a Java codebase where String isbn and String edition are used inconsistently, into a BookIdentifier Value Object with built-in validation and clear domain meaning.

Quick Start

Apply the value-object-pattern-applied skill to refactor primitive parameters in the estimateShippingCost method into an Address Value Object.
