Update Domain Model

When to use

Use this skill when the primary change is to business concepts, invariants, aggregates, entities, enums, or value objects.

Primary boundary

Business/domain boundary.

Out of scope

• endpoint transport design
• application orchestration or validation flow design
• infrastructure adapter implementation
• project bootstrap work

Typical inputs

• business concept
• required properties
• invariants or rules
• relationships to other domain types
• persistence impact if known

Workflow

1. Confirm the change belongs in the domain boundary.
2. Make invariants and business rules explicit.
3. Keep framework, transport, and persistence concerns out of the domain model.
