Throughout this series, we have relied on a single orchestration pattern: the LLM decides what to do next. The orchestrator receives a user message, its system prompt teaches it which specialists exist, and the model picks the right one. For most interactions – “search for headphones,” “what is my order status,” “any coupons available?” – this works well. The LLM routes accurately, the specialist responds, and the orchestrator formats the answer.
