Q: How do I install junit?

Run npx skills add https://github.com/full-stack-skills/testing-skills --skill junit in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/junit/ (personal) or .claude/skills/junit/ (project).
