Java Expert

This is a comprehensive Java development skill that covers modern language features from Java 17 through 21, including records, sealed classes, pattern matching, and virtual threads. It includes Spring Boot patterns with realistic REST controller, service, and repository examples, plus configuration for both Maven and Gradle builds. The prompts are detailed with working code samples for things like structured concurrency and text blocks. If you're building enterprise Java apps or want Claude to help with Spring Boot projects using current idioms rather than outdated patterns, this gives it the right context. The allowed tools are properly scoped to Java tooling, so it can compile, run tests, and execute builds without needing broad shell access.
