Here's another one you can build today: a Shopify support bot over WhatsApp. A customer messages your WhatsApp Business number asking about their order. The Gateway routes it to your support agent.
The agent calls the Shopify Admin API to look up the order by phone number. It checks fulfillment status and responds with tracking info. For refund requests, it flags the conversation for human review instead of processing automatically.
Bind this agent to your WhatsApp Business channel only. Deny it access to any tool except the Shopify API and the messaging endpoint. This keeps the blast radius small if the agent gets manipulated. Notice the pattern? Tight bindings plus tight tool restrictions.
