Skill
A packaged capability an agent can install and use. Code, prompts, and tool wiring bundled as one unit.
A skill is the smallest deployable unit of agent capability. It bundles the prompts, code, schema, and external connections needed for one focused job.
Treat skills like npm packages: small, single-purpose, well-tested, versioned. A good skill is boring, predictable, and obvious in scope. The best skills do one thing and explain themselves to the agent in three sentences.
