After creating the agent, configure its orchestration capabilities and knowledge settings. Select the Settings command in the upper right corner and configure the agent.
Your Interview Coordinator needs to communicate with the existing HR agent to retrieve candidate information. Navigate to the 1️⃣ Agents section and select 2️⃣ Add.
A new dialog appears, allowing you to choose between any of the following options:
- New child agent: to create a new child agent
- Select an agent in your environment: to select an already existing agent defined with Copilot Studio
- Connect to an external agent: to connect to any of the following external agents (preview)
- Microsoft Fabric: connect to a Fabric Data Agent
- Microsoft Foundry: connect to an agent in Microsoft Foundry
- Microsoft 365 Agents SDK: connect to an agent built with Microsoft 365 Agents SDK
- Agent2Agent: connect to an agent using A2A protocol
From the list of available Copilot Studio agents, select the HR Candidate Management agent (or similar name) that you created in previous labs. If you don't see it, ensure it's published and configured to allow connections from other agents. To check if the HR Candidate Management agent is configured to allow connections from other agents, edit the agent, go to Settings, and check that the option Let other agents connect to and use this one is enabled in the Connected agents section, like illustrated in the following screenshot.
Once you selected the HR Canidated Management agent, configure the connection:
- Description: Update the description to be more specific for this context:
HR system integration for retrieving and managing candidate information during
interview scheduling processes. Provides candidate lookup, data validation, and
comprehensive candidate details.
The description is used by the main agent to understand when the connected agent should be invoked. Try to be specific and clear in the description.
- Pass conversation history: Keep this enabled to maintain context during agent handoffs
Select Add and configure to establish the connection between agents. Once the connected agent is defined and configured, you can see it in the list of Agents for the current agent and you are presented with a page to manage the configuration of the connected agent.
In this exercise you will create a specialized child agent that handles the meeting creation and calendar management aspects of interview scheduling.
In your Interview Coordinator agent, navigate to the 1️⃣ Agents section and select 2️⃣ Add an agent.
Select New child agent to create a new child agent.
Configure the child agent with these settings:
Interview Scheduler
-
When will this be used?: Select The agent chooses to allow the agent to respond to coordination requests from the main agent
-
Description:
Helps scheduling an interview with a candidate. Requires information like the email
of the candidate and the date and time of the meeting.
You are the Interview Scheduler, a specialized agent focused on creating and managing
interview meetings. When invoked by the Interview Coordinator, you:
1. Process candidate information received from the main agent
2. Create appropriate calendar meeting invitations
3. Include relevant candidate details in meeting descriptions
4. Send meeting invitations to appropriate stakeholders
5. Provide confirmation details back to the coordinator
For each interview scheduling request:
- Create a 1-hour meeting slot (suggest next business day if no specific time provided)
- Include candidate name, role, and key skills in the meeting title and description
- Invite the requesting user and any additional specified interviewers
- Set appropriate meeting location (in-person, Teams, etc.)
- Include candidate resume/profile information in meeting notes
Always confirm successful meeting creation with meeting details including date, time,
attendees, and meeting link if applicable.
Select the Save command in the upper right corner of the screen to save the new child agent. You should see a green confirmation message stating that the child agent was created.
To enable the Interview Scheduler to create calendar meetings, you need to add a specific MCP server integration for meetings management.
In the Tools section of the Interview Scheduler child agent, select Add.
- Choose 1️⃣ Model Context Protocol to filter the available MCP servers
- Search for 2️⃣ Calendar in the search box and hit the 3️⃣ search command
- Select the 4️⃣ Meeting Management MCP Server
- Connect to the Meeting Management MCP Server
- Once the connection is configured, select Add and configure to finalize the configuration of the tool
Once the connection is established and the MCP server is added to the child agent, you will see the panel with the configuration of the new tool. Update the Name accordingly to the following value:
Manage meetings
This integration allows the child agent to:
- Create calendar events
- Send meeting invitations
- Manage meeting details and attendees
Go back to the Overview tab of the child Interview Scheduler agent, selecting the left arrow beside the name of the tool, and complete the configuration of your Interview Scheduler child agent:
-
Open the Details section, expand the Advanced panel and set the Priority to 1 to ensure this agent has high priority for interview scheduling tasks
-
Condition: Optionally, add conditions to limit when this agent activates. For example, you might want it to only activate for messages containing interview-related keywords
-
Ensure the Enabled toggle is turned on
-
Select Save to create the child agent
Your Interview Scheduler child agent is now configured and ready to handle meeting creation tasks when invoked by the main Interview Coordinator agent.
In this exercise you will implement and test the complete connected agents workflow for interview scheduling.
To enable proper agent coordination, you need to reference the child agent and connected agent in your main agent's instructions.
Navigate to the Overview section of your Interview Coordinator agent and update the Instructions field selecting the Edit command:
- Place your cursor in the instructions text where you want to reference agents
- Type
/
to open the reference menu
- Select the Interview Scheduler child agent from the list
- Also reference the HR Candidate Management connected agent
Your updated instructions should look like this:
You are the Interview Coordinator, responsible for managing end-to-end interview
scheduling processes. Your role includes:
1. Understanding user requests for interview scheduling
2. Coordinating with /HR Candidate Management agent to retrieve candidate information
3. Delegating to /Interview Scheduler child agent for meeting creation
4. Providing comprehensive feedback to users about scheduled interviews
When a user requests to schedule an interview:
- First, use /HR Candidate Management to identify and validate the candidate
- Extract necessary candidate details (name, email, current role, skills)
- Coordinate with /Interview Scheduler to create the meeting with candidate details using the ID of the calendar with name "main" of the current user
- Confirm successful scheduling with relevant details
Always ensure proper validation of candidate data and provide clear communication
throughout the process. Handle errors gracefully and provide informative feedback
when coordination between agents fails.
Select Save to update the instructions with agent references.
In this exercise you will test the agent scheduling a real interview in your agenda.
Now test the complete agent-to-agent workflow to ensure proper coordination between all components.
In the test panel, try a request like:
Retrieve information about candidate [email protected] and schedule an interview with her for next Monday 10am.
Watch in the test panel as the agent:
- Processes your request
- Calls the HR Candidate Management agent to find Alice Johnson
- Retrieves candidate details
- Invokes the Interview Scheduler child agent
- Creates the calendar meeting, requesting you to connect to the Meeting Management MCP server if it is the first time you use it
- Provides confirmation
And in the following screenshot you can see a sample of the interview meeting scheduled by the agent relying on both the child and the connected agent.
