Is the Java Cache skill free?

Yes. The skill itself is free from ducpm2303/claude-java-plugins. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Java Cache SkillProof Score?

8.8/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 7/10, docs & honesty 5/5.

How do I install Java Cache?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Java Cache with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Baseline Spring caching advice already covers the annotations correctly, but the skill's checklist catches a real bug baseline glossed over — the @Cacheable proxy-bypass footgun when a method calls itself on the same bean — plus it forces explicit maximumSize/TTL and actuator cache-metrics steps baseline would only add if asked.

What Java Cache does

Detects the Spring Boot cache provider (Redis, Caffeine, plain ConcurrentHashMap, or none) from pom.xml/build.gradle and the Boot version, then walks through setup, @Cacheable/@CacheEvict/@CachePut usage, and an 11-point review checklist covering proxy-bypass, null caching, serialization and TTL. Triggers when a user asks to add caching, configure Redis or Caffeine, use the Spring cache annotations, or review existing cache config.

How to install Java Cache

git clone https://github.com/ducpm2303/claude-java-plugins
cd claude-java-plugins
mkdir -p ~/.claude/skills
cp -r plugins/java-spring/skills/java-cache ~/.claude/skills/java-cache

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Java Cache

/java-cache Spring Boot cache setup, review checklist and eviction patterns for Redis and Caffeine.

It also activates on plain-language prompts like these:

Add Caffeine caching to my ProductService.findById method in Spring
Review my Spring Boot Redis cache config for the proxy-bypass bug
Set up cache eviction on update and delete for this Spring service
