ddd-tactical-patterns

authentic

Apply DDD tactical patterns in code using entities, value objects, aggregates, repositories, and domain events with explicit invariants.

When to use

• Translating domain rules into code structures.
• Designing aggregate boundaries and invariants.
• Refactoring an anemic model into behavior-rich domain objects.
• Defining repository contracts and domain event boundaries.

When not to use

• You are still defining strategic boundaries.
• The task is only API documentation or UI layout.
• Full DDD complexity is not justified.
• This skill does not define deployment architecture.
• It does not choose databases or transport protocols.
• It should be paired with testing patterns for invariant coverage.
