Domain modeling principles: parse-don't-validate, make invalid states unrepresentable, primitive obsession detection, semantic types, and domain veto authority. Activate when designing types, reviewing code for domain integrity, or when domain review is needed in a TDD cycle.

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.
