Most AI agent tutorials end at “hello world.” You build a single agent with one or two tools, it answers a few questions, and that is it. The gap between that tutorial and a production system with multiple agents, authentication, observability, and a real frontend is enormous.

You have five specialist agents, each with domain expertise. One handles product search and recommendations. Another manages orders and returns. A third deals with pricing, promotions, and loyalty discounts. The fourth analyzes product reviews and sentiment. The fifth tracks inventory and shipping.
