domain-driven-design

SKILL.md

This skill provides guidance for domain modeling based on Rich Hickey's data-oriented design principles and Scott Wlaschin's type-driven design approach. Focus on building systems that make illegal states unrepresentable, prioritize data and transformations over objects and methods, and establish a ubiquitous language that bridges technical implementation and business domain.

Aggregate: A cluster of entities and value objects treated as a single unit for data changes.

Aggregate Root: The single entity through which all external access to the aggregate must pass.

每當進行領域建模時都應該使用這項技能。它根據 Rich Hickey 和 Scott Wlaschin 的原則為類型驅動和數據驅動設計提供專門指導。該技能有助於在現有領域模型中將當前建模置於上下文中，識別不一致之處，構建通用語言，並創建可視化（Mermaid、Graphviz/DOT、ASCII 圖）以清晰地傳達領域概念。在設計類型、建模業務域、重構域邏輯或確保跨代碼庫的域一致性時使用此技能。 來源：bfollington/terma。
