Design and implement domain entities, DTOs, and data transfer objects following the project's domain-driven design patterns. Use this skill when creating or modifying domain entity classes in shared/domain/, DTO classes in features/{feature}/dto/, entity mappers in shared/mapper/, or shared type interfaces in packages/shared/types/src/dto/. This includes implementing the static factory pattern (Entity.create()), writing DTO validation decorators (class-validator), creating response DTOs with static from() methods, and defining shared interfaces that API DTOs must implement. Apply when working with @imkdw-dev/types package interfaces, ArticleContent value objects, or any file ending in .dto.ts, domain entities, or mapper classes.
