# Specification Generator
Generate DDD-compliant Specifications for encapsulating business rules and filtering logic.
## Specification Characteristics
- **Single Responsibility**: One business rule per specification
- **Composable**: AND, OR, NOT combinations
- **Reusable**: Same spec for validation and querying
- **Domain Language**: Named using ubiquitous language
- **Testable**: Easy to unit test in isolation
- **Immutable**: No state changes after creation
