SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill streamlines the creation, review, and implementation of use cases within the CodeLeap project, ensuring consistent application of the project's patterns and best practices.

Core Features & Use Cases

Use Case Implementation: Guides the creation of new use cases following the UseCase<IN, OUT> contract.
Validation & Orchestration: Ensures data validation via Value Objects and delegates persistence to API adapters.
Use Case: When developing a new feature that requires creating a user profile, use this Skill to ensure the CreateUserUseCase correctly validates input, interacts with the user repository, and returns a Result object.

Quick Start

Use the use-case skill to create a new use case for user registration.

FAQPage Schema

How do I orchestrate application logic using use cases and the Result pattern?▼

To orchestrate application logic using use cases and the Result pattern, implement the UseCase<IN, OUT> contract to handle data validation via Value Objects and return consistent Result objects.

What is the best way to validate data in a domain-driven design use case?▼

Validating data in a domain-driven design use case is best handled using Value Objects. This approach ensures data integrity before delegating persistence operations to API adapters.

How do I structure API integration within an application logic layer?▼

Structure API integration within application logic by delegating persistence operations to API adapters. This keeps use cases focused on validation and deterministic task orchestration rather than direct API calls.

Can I use this approach to review and standardize existing use cases?▼

Yes, you can use this approach to review existing use cases. It ensures consistent application of project patterns by verifying adherence to the UseCase<IN, OUT> contract and Result object returns.

Do I need external dependencies to implement the Result pattern in my use cases?▼

No external dependencies are required to implement the Result pattern in your use cases. The skill operates independently to guide the creation and orchestration of deterministic application logic.

When should I not use a use case pattern for application logic?▼

You should not use a use case pattern for application logic when a task lacks deterministic validation or API interaction requirements. It is designed specifically for orchestrating complex validation and persistence operations.
