概要
This skill provides specialized guidance for developing robust backend services within the Kotlin and Spring Boot ecosystem. It streamlines the creation of clean API architectures through Controller-Service-Repository layering, DTO patterns, and global exception handling. A primary focus is placed on high-fidelity integration testing using real in-memory databases rather than mocks, ensuring that database constraints and transaction boundaries are accurately validated. It also includes standardized protocols for identifying and reporting architectural blockers, making it ideal for complex enterprise projects like catering or task management systems.
