# Overview of the Declarative Agent with Skill template

With the declarative agent, you can build a custom version of Copilot that can be used for specific scenarios, such as for specialized knowledge, implementing specific processes, or simply to save time by reusing a set of AI prompts. This template includes a **hello-atk** agent skill that demonstrates how skills work by greeting users with a fun fact about declarative agents and Microsoft 365 Copilot.

## Get started with the template

> **Prerequisites**
>
> To run this app template in your local dev machine, you will need:
>
> - [Node.js](https://nodejs.org/), supported versions: 18, 20, 22
> - A [Microsoft 365 account for development](https://docs.microsoft.com/microsoftteams/platform/toolkit/accounts).
> - [Microsoft 365 Agents Toolkit Visual Studio Code Extension](https://aka.ms/teams-toolkit) version 5.0.0 and higher or [Microsoft 365 Agents Toolkit CLI](https://aka.ms/teamsfx-toolkit-cli)
> - [Microsoft 365 Copilot license](https://learn.microsoft.com/microsoft-365-copilot/extensibility/prerequisites#prerequisites)

1. First, select the Microsoft 365 Agents Toolkit icon on the left in the VS Code toolbar.
2. In the Account section, sign in with your [Microsoft 365 account](https://docs.microsoft.com/microsoftteams/platform/toolkit/accounts) if you haven't already.
3. Select `Preview Local in Copilot (Edge)` or `Preview Local in Copilot (Chrome)` from the launch configuration dropdown.
4. Select your declarative agent from the `Copilot` app.
5. Ask a question to your declarative agent and it should respond based on the instructions provided.

The following are Microsoft 365 Agents Toolkit specific project files. You can [visit a complete guide on Github](https://github.com/OfficeDev/TeamsFx/wiki/Teams-Toolkit-Visual-Studio-Code-v5-Guide#overview) to understand how Microsoft 365 Agents Toolkit works.

| File           | Contents                                                                                                                                  |

| `m365agents.yml` | This is the main Microsoft 365 Agents Toolkit project file. The project file defines two primary things: Properties and configuration Stage definitions. |

## Extend the template

- [Add conversation starters](https://learn.microsoft.com/microsoft-365-copilot/extensibility/build-declarative-agents?tabs=ttk&tutorial-step=3): Conversation starters are hints that are displayed to the user to demonstrate how they can get started using the declarative agent.
- [Add web content](https://learn.microsoft.com/microsoft-365-copilot/extensibility/build-declarative-agents?tabs=ttk&tutorial-step=4) for the ability to search web information.
- [Add OneDrive and SharePoint content](https://learn.microsoft.com/microsoft-365-copilot/extensibility/build-declarative-agents?tabs=ttk&tutorial-step=5) as grounding knowledge for the agent.
- [Add Microsoft Copilot connectors content](https://learn.microsoft.com/microsoft-365-copilot/extensibility/build-declarative-agents?tabs=ttk&tutorial-step=6) to ground agent with enterprise knowledge.
- [Add API plugins](https://learn.microsoft.com/microsoft-365-copilot/extensibility/build-declarative-agents?tabs=ttk&tutorial-step=7) for agent to interact with REST APIs.

## Evaluating Agents

Install the Microsoft 365 Copilot Agent Evaluations CLI (`@microsoft/m365-copilot-eval`) NPM package to test, measure, and improve the quality of your agent with structured evaluations and rich result reports with AI-based scoring.

> Requires [Admin consent](https://github.com/microsoft/work-iq/blob/main/ADMIN-INSTRUCTIONS.md) at tenant level.

1. Run `npm install -g @microsoft/m365-copilot-eval`
2. Add the following environment variables. See [here](https://learn.microsoft.com/en-us/microsoft-365/copilot/extensibility/evaluations-cli-get-env-values) on how to get them.

    ```
    AZURE_AI_OPENAI_ENDPOINT=
    AZURE_AI_API_KEY=
    AZURE_AI_API_VERSION=
    AZURE_AI_MODEL_NAME=
    ```

3. Run `runevals` or `runevals --env dev`

A sample dataset `evals/prompts.json` is created in this project to help you get started right away. [Read more](https://learn.microsoft.com/en-us/microsoft-365/copilot/extensibility/evaluations-cli-overview).
