DTO

Use this skill when transport schemas must differ from internal models.

Workflow

1. Start with basic DTO configuration for a model.
2. Add abstract/custom DTO classes for reusable policies.
3. Control nested inclusion/exclusion explicitly.
4. Use DTOData patterns for safe write/update handling.

Coverage

• Basic DTO use.
• Abstract DTO extension patterns.
• Nested exclude/include handling.
• DTOData manipulation and validation flow.
