We'll next learn how to build a declarative agent for a "Business-to-Employee" use case which will act as an IT helpdesk agent.
NOTE
This lab will outline steps to add a Prompt as a tool. The following lessons will dive into adding knowledge sources and adding other tools available. Keeping it simple for your learning 😊
👩🏻💼 Understanding Business-to-Employee (B2E)
Business-to-Employee (B2E) refers to the interactions and services that a business provides directly to its employees. In the context of an agent, it means using the advanced capabilities of Copilot Studio to support and enhance the work experience of employees within the organization.
✨ Use case scenario
As an employee
I want to get quick and accurate help from the IT helpdesk agent for issues like device problems, network troubleshooting, printer setup
So that I can stay productive and resolve technical issues without delays
Let's begin!
Prerequisites
- Makers must have permissions to create in and have access to a Copilot Studio environment.
Licensing note
This lab will outline steps to add a Prompt as a tool. The following lessons will dive into adding knowledge sources and adding other tools available. Keeping it simple for your learning 😊
You do not need a Microsoft 365 Copilot user license to publish your declarative agent built in Copilot Studio to Microsoft 365 Copilot. However users of the published declarative agent in Microsoft 365 Copilot require a Microsoft 365 Copilot user license.
3.1 Create a declarative agent
Select Agents from the menu and select Copilot for Microsoft 365.

Great! We're now done entering details for our agents so let's proceed with creating our declarative agent. Select Create.

Once the agent has been provisioned, you'll see the details of the agent including the name, description, instructions and suggested prompts we defined during the agent creation experience. The starter prompts will also be displayed in the test pane on the right hand side. Users can select these starter prompts to begin interacting with the agent.
Scroll down and you'll also see the capabilities of adding knowledge, enabling web search (via Bing), the suggested prompts and the publish details of the declarative agent for Microsoft 365 Copilot.

Let's do a quick test of the agent we've created. Select one of the Starter Prompts in the test pane on the right hand side such as the
Explain IT Termsprompt.Our agent will then respond. Notice how it adhered to the instructions by providing bullet points into digestible parts and also provided a summary.

In a few minutes you've added a declarative agent for Microsoft 365 Copilot in Copilot Studio 🙌🏻
Next we'll learn how to add a tool to our agent, we'll create a prompt.
3.2 Create and add a prompt for your declarative agent
Scroll down to the Tools section and select + Add tool

The Tools modal will appear and you can either create a new tool or select from the list of tools available. By default, a list of Power Platform connectors is displayed. Since we are going to add a Prompt, select Prompt under Create new.

The Prompt modal appears, this is where we can define our prompt for our agent.
Enter a name for the prompt. Let's name our prompt
IT Expert.
Select the chevron icon next to the Model to see the different chat models you can choose from. The default model select is Basic GPT-4.1 mini. You'll see a list of OpenAI models and Anthropic models that you can select from. You also have the option to bring-your-own-model using Microsoft Foundry Models. We'll stick with the selected default model.

Next, we'll provide our prompt with instructions. There's 3 methods that you can choose from
- Use Copilot to generate instructions for you based on your description of what you want the prompt to do.
- Use a preset template from the prompt library to create a prompt.
- Manually enter your own instructions.
Let's first try using Copilot to generate instructions based on a description entered. Enter the following into the Copilot field and submit.
textI need an IT expert that can help answer questions related to networking, computer systems, user devices and anything else IT related
Copilot will then begin to generate a prompt for us.

The Copilot generated draft instructions will then appear.

Scroll down to the bottom of the instructions and you'll see the user input parameter already defined by Copilot. You then have the option to
- Keep the draft instructions generated.
- Refresh the draft instructions using Copilot.
- Clear the draft instructions.
Clear the draft instructions by selecting the trash bin icon and we'll next try the prompt library.

Select the prompt template link.

You'll see a list of prompt templates to choose from. These are from the Power Platform Prompt library.

Search for the
IT expertprompt and select it.
The prompt will then be added as the instructions with the input parameter as defined by the prompt template. Similar to the approach we took when providing instructions for our agent during the conversational creation experience with Copilot, this prompt template outlines
- a task,
- what type of inquiries it can handle,
- and the format of its response and the goal of the prompt.

Clear the instructions and we'll next try manually entering the instructions. We'll use the IT Expert prompt from the Power Platform Prompt library. Copy and paste the prompt.
textI want you to act as an IT Expert. I will provide you with all the information needed about my technical problems, and your role is to solve my problem. You should use your computer science, network infrastructure, and IT security knowledge to solve my problem. Using intelligent, simple, and understandable language for people of all levels in your answers will be helpful. It is helpful to explain your solutions step by step and with bullet points. Try to avoid too many technical details, but use them when necessary. I want you to reply with the solution, not write any explanations. My problem is [Problem]
Next, we can define the user input parameters of our prompt. These can be text and images, and sample data to test with. There's also the capability to ground the prompt with knowledge from Dataverse tables. For this exercise, we only have one user input to define which is the problem input. This is currently a placeholder in our prompt as
[Problem]. We'll now configure this input either by entering the/character or selecting +Add content and then select Text.
We can now enter a name for our input parameter and sample data.
Enter the following as the name
textproblem inputEnter the following as the sample data
textMy laptop restarted unexpectedly. Any advice?Then select Close.

The problem input parameter will now be added to the instructions with the configured sample data. We can now test our prompt!
Select Test to the test the prompt.

The model will be in-progress of generating a response.

The response will then display. Notice how the response provides headings with bullet points as per the instructions. Scroll down and review the remainder of the model response.

Before we save our prompt, let's learn about the settings that can be configured for this prompt. Select the ellipsis (...) icon.

Here we'll see several settings that can be configured.
- Temperature: Lower temperatures lead to predictable results, while higher temperatures allow more diverse or creative responses.
- Record retrieval: Specify the number of records retrieved for your knowledge sources.
- Include links in the response: When selected, the response includes link citations for the retrieved records.
- Enable code interpreter: When this option is turned on, the code interpreter feature becomes active, allowing the agent to generate and run code.
- Content moderation level: Lower content‑moderation levels allow more answers but increase the risk of harmful content. Higher moderation levels apply stricter filtering, reducing harmful content but also producing fewer answers.
Select the X icon to exit from Settings.

Select Save to save the prompt.

Next, select Add and configure to add the prompt to our declarative agent.

The prompt will now appear under Tools 🙌🏻

We'll next update our instructions to invoke the prompt and test our declarative agent.
3.3 Update instructions and test your declarative agent
Scroll up to the Details section and select Edit. This will enable the fields to be editable.

We can now update our instructions to invoke our prompt by referencing the name of the prompt. Clear the instructions, then copy and paste the following.
textWhen a user asks IT related questions such as questions on their device, run the "IT Expert- prompt". Use their question as the problem input of the "IT Expert- prompt".Notice how the final sentence is instructing the agent to use the question asked by the user as the value for the problem input parameter. The agent will use the question as the problem input for the prompt. Next, select Save.

We're now ready to test our updated instructions of our declarative agent. Select the refresh icon in the test pane.

Next, enter the following prompt below and submit.
textMy laptop restarted unexpectedly. Any advice?
The agent invokes the prompt and responds.


Model responses may differ across sessions
AI-generated responses are non‑deterministic, so the same prompt may produce slightly different results each time.
Let's now publish our declarative agent 😃
3.4 Publish your declarative agent to Microsoft 365 Copilot and Microsoft Teams
Select Publish.

A modal will appear which displays the Channels and publishing details that can be updated.
- Channels: The agent will be published to Microsoft 365 Copilot and Microsoft Teams.
- Agent app information: This is what will be displayed when the user adds the agent to Microsoft 365 Copilot or in Microsoft Teams. These are fields that can be updated as needed.

For example, you can update the Short description, Long description, Developer name with your name.
TIP
If you don't see all the fields displayed on your browser, try zooming out e.g. 75%
Select Publish. Copilot Studio will then begin publishing the agent.

When publishing is completed, we'll see the Availability options of the agent.
Availability option Description Share Link Copy the link to distribute it with shared users to open the agent in Microsoft 365 Copilot Show to my teammates and shared users Lets you grant access to others to participate in authoring the agent, or to security groups to grant them access to use the agent in Microsoft 365 Chat or Microsoft Teams. Show to everyone in my org Submit to the tenant admin to add to the organizational catalog for all tenant users to add the agent. The agent will show under Built by your org in Microsoft 365 Copilot and in Microsoft Teams Download as a .zip Download as a zip file to upload as a custom app in Microsoft Teams 
Let's take a look at sharing the agent. Select Show to my teammates and shared users. A pane will appear where you can search for users you want to to share the agent with either by entering their name, an email or a security group. You can review this list anytime to edit who has access to the agent.
There's also a checkbox:
- Show in Built By Your Colleagues - agent becomes available in the Built with Power Platform section of the Teams app store.
For more details, refer to Connect and configure an agent for Teams and Microsoft 365.
Select Cancel or the X icon to exit from the pane.

Select Copy and in a new browser tab, paste the link.

Microsoft 365 Copilot will load and a modal will appear with the agent app details. Notice how the developer name, the short description and long description is displayed. These are from the publishing details updated in an earlier step.
Select Add.

Our declarative agent will load next. We can see the suggested prompts to select from which quickly enables users to seek immediate help.
Select one of the suggested prompts which will automatically prepopulate the message Copilot field. Submit the question to Copilot.

Select Always allow to give your declarative agent permission to invoke the IT Expert prompt.

The agent will then invoke our IT Expert prompt and we'll see the model response returned as a message in our declarative agent.

Scroll down to see the full details of the response.

But how do we know the declarative agent invoked the prompt? 👀 Well, here's a tip!
TIP
You can test and debug agents in Microsoft 365 Copilot by enabling developer mode.
Enter the following in the message Copilot field and submit.
text-developer onA confirmation message will appear to let you know developer mode is now enabled.

Submit the following question to invoke the prompt.
textMy laptop restarted unexpectedly. Any advice?
We'll see a model response from our IT Expert prompt again returned as a message. Scroll down to the bottom of the message and a card with debug information is displayed.
Expand Agent Debug Info by selecting it.

Here you'll find information on the agent metadata that occurred at runtime.
In our use case, we'll be focusing on the Actions section:
- Matched actions highlight the current status of functions found during the app's search.
- Selected actions highlight the current status of functions chosen to run based on the app's decision-making process.
So here we can see the agent orchestrator chose to invoke the IT Expert prompt as per the instructions of our declarative agent.

This is further outlined in the Executed Actions section which also tells us that it successfully invoked the prompt and used our question as the value for our
problem inputparameter.

To turn off developer mode, enter the following in the message Copilot field and submit.
text-developer offA confirmation message will appear to let you know developer mode is disabled. Cool, now you know how to verify whether your declarative agent in Microsoft 365 Copilot invoked your prompt 🌞

We'll now test our agent in Microsoft Teams. Navigate to Apps using the left hand side menu and select Teams under the Apps section.

Microsoft Teams will then load in a new browser tab and we'll then be presented with the terms of use for Microsoft 365 Copilot, select Agree.

Microsoft 365 Copilot will then load by default, with the right hand side pane listing all of your available agents, including the Contoso Tech Support Pro declarative agent.

Select ellipsis icon (...) on the left hand side menu. Either search for Contoso Tech Support Pro in the search field or if you see the agent, select it.
You can also right-click on your mouse to Pin the agent for quick access on the left hand side menu in Microsoft Teams.

We'll then see our agent load. 1. Let's next test our agent. Enter the following prompt and submit.
