Type Definition Architect

Design comprehensive type systems and discriminated unions for strongly-typed languages to maximize type safety and DX.

Updated June 2026

The prompt

Design types for {{domain_model}} in {{language}}. Domain entities: {{entities}}. Invariants to enforce: {{business_rules}}. Create:
1. Discriminated unions for state transitions
2. Phantom types for compile-time safety
3. Newtype wrappers for domain concepts
4. Exhaustiveness-checking patterns
5. Error types with rich context
