Interoperability

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.

Every agent in ECommerce Agents has hand-coded tools. The inventory agent has check_stock, get_warehouses, and estimate_shipping as @tool-decorated Python functions that query PostgreSQL directly. The product discovery agent has search_products and semantic_search. The order management agent has get_orders and create_order. Each tool is tightly coupled to the agent that owns it, written in the same language, deployed in the same container, and imported as a Python module.
