installation

A skill is a directory containing a SKILL.md. Install it in your agent's skills directory: home for all projects (~/.claude/skills/), project root for one project (<project>/.claude/skills/).

To install all skills at once, run the installSkills script, or unzip a zip from the skills release. No JDK, no git.
