DDD Tactical Patterns

Use this skill when

• 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.

Do not use this skill when

• You are still defining strategic boundaries.
• The task is only API documentation or UI layout.
• Full DDD complexity is not justified.

Instructions

1. Identify invariants first and design aggregates around them.
2. Model immutable value objects for validated concepts.
