Java stays correct when data is immutable, resources close themselves, absence is typed and shared state is guarded. For the builder and the reviewer of a Java diff; the repo's config and existing code win over it.
Java Conventions is a community-contributed Claude Code skill in the languages sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/java-conventions/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when a ticket adds or changes Java code and it must follow the repo's Java conventions — Effective Java, modern Java (records, sealed types, pattern matching, switch expressions), Optional discipline, immutability, try-with-resources, thread safety and virtual threads, Spring Boot constructor injection, and JUnit 5 + Mockito tests. Invoke for "add this in Java", "fix the Java build", "add a Spring endpoint/service", or as the language pack for any Java change or Java review.
The Java Conventions Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 213,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
