How does this skill handle architectural boundaries?

It enforces a strict rule where application services must inject model services instead of repositories, ensuring that business logic is never tightly coupled to the data access layer.

When should I use the Rockets Business Logic skill?

Use this skill after your basic CRUD modules are generated to implement custom actions, complex workflows, state transitions, or any logic that crosses multiple entity boundaries.

Does it support database transactions?

Yes, it provides specific patterns for Pattern 9: Transactional Multi-Entity operations, ensuring atomicity across complex, multi-service workflows.

Can I use this for event-driven architectures?

Yes, the skill includes patterns for setting up NestJS event emitters and listeners to handle decoupled side effects like notifications or audit logging.

API開発

Implements complex business logic patterns including state machines, event-driven workflows, and cross-service orchestration for robust backend applications.

This skill empowers Claude to handle advanced backend requirements that go beyond simple CRUD operations. It provides a structured framework for implementing state machines, approval workflows, multi-entity transactions, and external API integrations while enforcing strict architectural boundaries between application services and repositories. By following predefined logic patterns and decision trees, it ensures that custom business rules are consistent, testable, and maintainable across complex software modules, specifically designed for NestJS and TypeORM environments.
