This one gives Claude deep knowledge of Spring Boot and the broader Spring ecosystem, including JPA, Security, and microservices patterns. Use it when you're building REST APIs, setting up dependency injection, or wiring together Spring Data repositories with proper service layers. The skill covers real implementation details like JWT authentication filters, pagination with Pageable, and transaction management, not just surface-level autoconfiguration stuff. It's opinionated toward modern Spring Boot practices with records for DTOs and constructor injection. Good for both greenfield microservices and adding endpoints to existing Spring applications, though you'll still need to know your way around Maven or Gradle.
