What is the difference between a skill and a raw LLM call?

A raw LLM call is freeform — the user crafts a prompt, picks a model, hopes for the best. A skill is governed — versioned, audience-scoped, retrieval-bound, output-validated, audit-logged, cost-metered. Users invoke skills by name; the platform orchestrates the call. Skills are the production interface; raw calls are for development only. scale
