Does this skill support older Java versions?

While it is optimized for Java 21+, many conventions apply to Java 11 and 17, though features like Records, Sealed Classes, and Virtual Threads require their respective minimum versions.

Can I use this with Kotlin projects?

Yes, while the syntax focus is Java, the underlying Spring Boot best practices and JVM architectural patterns are highly relevant to Kotlin development.

How does this help with Java code reviews?

Claude uses this skill to identify verbose anti-patterns, such as traditional POJOs where Records should be used, or manual casting where Pattern Matching is more appropriate.

Does it include Spring Boot specific configurations?

Absolutely. It provides specific guidance for Spring Boot 3.2+, including how to enable Virtual Threads via application properties and how to structure modern controllers.
