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.

도메인 모델링 원칙: 구문 분석 안 함, 유효하지 않은 상태를 표현할 수 없도록 만들기, 원시적 집착 감지, 의미 유형 및 도메인 거부권. 유형을 설계하거나, 도메인 무결성을 위한 코드를 검토하거나, TDD 주기에서 도메인 검토가 필요할 때 활성화하세요. 출처: jwilger/agent-skills.
