jvm-skills

JVM coding best practices, testing, and commit workflows

Guides coding agents through JVM development with opinionated best practices for jOOQ, Kotlin, Spring Boot, and Gradle. Covers test-driven bug fixes, Kotest test writing, mutation testing, coverage improvement, and clean commit grouping. Eliminates shallow generic advice by teaching patterns a senior JVM engineer would actually apply.
