domain-modeling

Value: Communication -- domain types make code speak the language of the business. They turn implicit knowledge into explicit, compiler-verified contracts that humans and AI can reason about.

Teaches how to build rich domain models that prevent bugs at compile time rather than catching them at runtime. Covers primitive obsession detection, parse-don't-validate, making invalid states unrepresentable, and semantic type design. Independently useful for any code review or design task, and

provides the principles that domain review checks for in the TDD cycle.

領域建模原則：解析而不驗證、使無效狀態無法表示、原始痴迷檢測、語意類型和領域否決權。在設計類型、審查程式碼的域完整性或在 TDD 週期中需要網域審查時啟動。 來源：jwilger/agent-skills。
