Is the Java Best Practices skill free?

Yes. The skill itself is free from Taoidle/plan-cascade. SkillProof publishes the install command and an independent test verdict at no cost.

Does Java Best Practices work with Claude Code?

It is in our test queue — we run every skill on real work before issuing a verdict, and this one is scheduled.

How do I install Java Best Practices?

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 Best Practices 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.
