Study notes
Take it with you:
• An agent skill is one job, packaged: when to use it, how to do it, and what it needs.
• Write each description in your customer’s words. It’s all that routing reads.
• Own tools are automatic, shared ones only when listed. References are shared by every skill.
• One skill can call another. The caller waits, then picks up where it stopped.
