Agents are the bots that a Concierge Bot will communicate with to fulfill user requests and answer questions. This is all orchestrated by a well trained LUIS app that knows where to direct questions.
From the Concierge Bot edit screen, click the Agent Bot Configuration tab. Click on Select LUIS App to configure the LUIS app to use for the Concierge Bot.
Once a LUIS App is selected, this section will show all of the Intents available to assign to agents. The intent will be outlined in blue if it has been assigned correctly.
Any bot that is an agent and not using Operator Mode will have to send an event back to the Concierge when it is ready to pass scope back. If you are building your bots in AtBot, then you can use the Send Event flow action or the Signal Response JSON in the Send Reply action. In either of those, you will send a JSON object that looks like this:
If you have built a custom bot using Microsoft Bot Framework code, you can see the External Bot documentation for an example of how to send the EndSkill event.
