Java Pro

If you're building with Java 21+ and want Claude to know about virtual threads, pattern matching, sealed classes, and the rest of the modern JVM stack, this gives it that context. It covers Spring Boot 3.x patterns, GraalVM native image compilation, and contemporary concurrency approaches with Project Loom. The skill leans heavily into enterprise architecture stuff like microservices patterns, Spring Security 6, and production observability. Most useful when you're working on greenfield projects or modernizing existing Java apps to take advantage of recent language features. It's comprehensive enough that you'll probably want to be selective about when you invoke it rather than having it active by default.
