In between them, there are one or many other nodes that contain the logic that we want to implement in the flow. Those nodes, in the context of prompt flow, are called tools. Each tool can accept one or multiple inputs and produce one or multiple outputs, so a connection is established between nodes when one node receives an output from another. So for example, let's take the Lookup tool and then the Inputs node. So here, in the Inputs node, you can see that we're using this variable named question of type string. This is actually the prompt that the user is going to send to this copilot. And then, check this out, here in the Lookup tool, we're using question that comes from Inputs.
