Author a new, well-formed Claude Code skill, agent, or hook from a one-line intent. Decides the right artifact type (skill vs agent vs hook) and placement (global vs project), then writes a correct SKILL.md / agent file / settings.json hook with engineered trigger phrasing, a clear procedure, and guardrails. Global and project-agnostic. Trigger when the user says "new skill", "new-skill", "create a skill", "make an agent", "scaffold a skill/agent/hook", or "author a Claude command".
