What is a Skill?

A Skill is a reusable set of instructions and supporting files that teaches an AI agent how to handle a kind of task. It changes the agent's behavior; it is not a model, plugin package or API by itself.

In practice, a Skill usually lives in a SKILL.md file. The agent discovers or loads it when the task matches its description, then follows its workflow and constraints.
