What problem does it solve?

This skill provides ready-to-use Kotlin/Spring backend patterns to standardize entity, service, repository, and controller implementations.

Core Features & Use Cases

• Entity Pattern: Kotlin data class with id, createdAt, updatedAt.
• Service Pattern: Service layer coordinating repository and related services with idempotent-like patterns.
• Repository Pattern (JOOQ): Repository that uses DSL, mapping to entities.
• Controller Pattern: REST controller exposing endpoints and delegating to services.
• API Interface Pattern: API interface with endpoint definitions.
• DTO Pattern: Data Transfer Objects for requests and responses.
• Exception Pattern: Typed exceptions for common error cases.
• Null Safety Guidelines: Guidelines to use safe calls, let, and single/first.

Quick Start

Provide a ready-to-use Kotlin/Spring backend pattern template for an EntityName domain, including a service, repository, controller, DTOs, and necessary null-safety guidance for a typical CRUD workflow.
