Tutorial - Build Custom Copilot - Teams

This tutorial shows how to create a custom copilot with Teams AI library using Teams Toolkit to chat with your data on Azure OpenAI. Teams AI library streamlines the process of building intelligent Teams apps by using the AI components and Large Language Models (LLMs) of your choice.

In this tutorial, you'll learn:

How to setup your data on Azure OpenAI.
How to create a new custom copilot with Teams Toolkit.
How to interact with your LLMs and data.
The directory structure of your custom copilot.

Prerequisites

Ensure you install the following tools for building and deploying your apps:

	Install	For using...
	Teams Toolkit	A Microsoft Visual Studio Code extension that creates a project scaffolding for your app. Use the latest version.
	Node.js and NPM	Back-end JavaScript runtime environment. For more information, see Node.js version compatibility table for project type.
	Microsoft Edge (recommended) or Google Chrome	A browser with developer tools.
	Visual Studio Code	JavaScript, TypeScript, or SharePoint Framework (SPFx) build environments. Use the latest version.
	Azure OpenAI	First create your OpenAI API key to use OpenAI's GPT. If you want to host your app or access resources in Azure, you must create an Azure OpenAI service.

Let's customize the prompt for your custom copilot.

Go to src/prompts/chat/skprompt.txt and update the following code in skprompt.txt file:

The following is a conversation with an AI assistant, who is an expert on answering questions over the given context.
Responses should be in a short journalistic style with no more than 80 words.

Screenshot shows skprompt in explorer in Visual Studio Code.

Go to the config.json file under prompts/chat. Add the following code inside the completion brackets and replace the endpoint, index_name and key values with your Azure AI Search resource details:

   "data_sources": [
     {
            "type": "azure_search",
            "parameters": {
                 "endpoint": "AZURE-AI-SEARCH-ENDPOINT",
                 "index_name": "YOUR-INDEX_NAME",
                 "authentication": {
                       "type": "api_key",
                       "key": "AZURE-AI-SEARCH-KEY"
                   }
             }
       }
     ]

Go to src/app/app.js file and add the following variable inside OpenAIModel:
```
azureApiVersion: '2024-02-15-preview'
```
From the left pane, select Run and Debug (Ctrl+Shift+D).
Select Debug in Test Tool (Preview).
Select the F5 key.
Custom copilot runs within the Teams App Test Tool, which opens in your browser.
