🎥 Watch the walkthrough
Mission Brief
Welcome back, Recruit. In this mission, you will design, equip, and deploy a Declarative Agent: a specialized agent embedded directly in Microsoft 365 Copilot and Microsoft Teams.
Unlike traditional agents, declarative agents operate with a defined mission (instructions), tools (prompts/connectors), and strategic access to internal intelligence such as SharePoint and Dataverse. Your job is to build this agent using Microsoft Copilot Studio, a no-code command center for bringing your agent’s skills and purpose to life.
Let’s get started.
Important: This mission uses the Copilot Studio classic experience If your Copilot Studio screen looks different from the screenshots in this lab, turn off New Experience in the upper-right corner to switch back to the classic experience used here.
Objectives
In this mission, you will learn how to:
- Understand what declarative agents are and how they extend Microsoft 365 Copilot
- Compare Microsoft Copilot Studio with Agent Builder when building declarative agents
- Create a declarative agent for Microsoft 365 Copilot in Copilot Studio
- Add an AI prompt as a tool
- Publish and test a declarative agent in Microsoft 365 Copilot and Microsoft Teams
What is a declarative agent for Microsoft 365 Copilot?
Declarative agents are tailored versions of Microsoft 365 Copilot. You can create a personalized Copilot experience for a specific business task by providing instructions that support a particular process, grounding it in organizational knowledge, and extending it with tools.
Why build a declarative agent with Microsoft Copilot Studio?
If you have already explored Agent Builder in Microsoft 365 Copilot, you may wonder why you would build a declarative agent in Copilot Studio.
Microsoft Copilot Studio offers a broader set of tools and capabilities for declarative agents that go beyond the limits of Agent Builder. Like Agent Builder, it does not require programming knowledge, but it gives you more control over how a declarative agent is configured.
Feature comparison
The following table highlights the differences between building a declarative agent with Agent Builder in Microsoft 365 Copilot and extending Microsoft 365 Copilot in Copilot Studio.
| Feature | Agent Builder in Microsoft 365 Copilot | Extend Microsoft 365 Copilot in Copilot Studio |

Lab 03: Create a declarative agent for Microsoft 365 Copilot
Next, you will create a declarative agent for a “Business-to-Employee” use case that acts as an IT helpdesk agent.
Note This lab covers the steps to add a Prompt as a tool. Later lessons go deeper into adding knowledge sources and other available tools. We will keep this simple for learning 😊
Understanding Business-to-Employee (B2E)
Business-to-Employee (B2E) refers to interactions and services that a business provides directly to its employees. In the context of agents, it means using the advanced capabilities of Copilot Studio to support and improve the work experience of employees inside 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.

-
Now add prompt instructions. There are three ways to do this.
- Let Copilot generate instructions from a description
- Use a preset template from the prompt library
- Enter instructions manually
-
First, try giving Copilot a description and having it generate instructions. Enter the following in the Copilot input box and submit it.
I need an IT expert that can help answer questions related to networking, computer systems, user devices and anything else IT related
- Copilot starts generating a prompt draft.
- The generated draft instructions appear.
-
At the bottom of the instructions, you will see the user input parameter created by Copilot. From here, you can:
- Keep the generated draft
- Regenerate the draft with Copilot
- Clear the draft
This time, clear it with the trash bin icon, then try the prompt library approach.
- Select the prompt template link.
- A list of templates from the Power Platform Prompt library opens.
- Search for the
IT expertprompt and select it.
- The template is added as instructions, along with its input parameter. This template defines:
- the task to perform
- the types of inquiries it can handle
- the response format and goal of the prompt
- Clear the instructions again, and this time use manual entry. Copy and paste the IT Expert prompt from the Power Platform Prompt library.
I 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]
- Now define the user input parameter. You can add text, images, sample data, and grounding from Dataverse tables. For this example, configure just one problem input for the
[Problem]placeholder. Type/or select +Add content, then choose Text.
- Enter the input parameter name and sample data.
Name:
problem input
Sample data:
My laptop restarted unexpectedly. Any advice?
After entering them, select Close.
- When the problem input parameter is added to the instructions, you can test the prompt. Select Test.
- The model starts generating a response.
- Review the generated response. Check that it includes headings and bullets as instructed. Scroll down to review the rest of the model response.
- Before saving, let’s review the settings you can configure for this prompt. Select More options (…).
- You can configure the following settings.
- Temperature: Lower values produce more predictable results; higher values allow more varied and creative responses
- Record retrieval: The number of records retrieved from knowledge sources
- Include links in the response: Include citation links in the response
- Enable code interpreter: Allow the agent to generate and run code
- Content moderation level: Lower levels allow more answers but increase risk; higher levels filter more strictly
After reviewing them, close Settings with the X icon.
- Select Save to save the prompt.
- Next, select Add and configure to add the prompt to the declarative agent.
- The Prompt now appears under Tools.
Now update the instructions so the agent actually invokes this Prompt.
3.3 Update instructions and test your declarative agent
- Scroll up to the Details section and select Edit. The fields become editable.
-
Update the instructions to reference the Prompt name. Clear the existing Instructions and paste the following.
When 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".The final sentence tells the agent to use the user’s question as the value for the
problem inputparameter. After entering it, select Save.
- Select the refresh icon in the right test pane to reset the test pane.
-
Enter the prompt below and submit it.
My laptop restarted unexpectedly. Any advice?
- The agent invokes the Prompt and responds.
Note: Model responses may differ each time AI-generated responses are non-deterministic, so the same prompt may produce slightly different results each time.
Now let’s publish the declarative agent.
3.4 Publish your declarative agent to Microsoft 365 Copilot and Microsoft Teams
- Select Publish.
-
A window opens where you can update Channels and publishing details.
