Introduction After encountering issues with creating a To-Do task action in my previous attempt Building a Copilot Agent with Teams Toolkit and Microsoft Graph Plugin to list my ToDo Tasks, I explored various methods to generate an OpenAPI specification for M365 Copilot Declarative Agents using the Ms Graph OpenAPI spec. This post outlines the different approaches I tried, the challenges I faced, and the lessons learned. Methods for Generating OpenAPI Specs 1.

Introduction In a previous post, I detailed the steps for Building a Copilot Agent with Teams Toolkit and Microsoft Graph Plugin to List My ToDo Tasks. However, I encountered issues with the CreateTask function when using an OpenAPI spec generated with Kiota. Upon investigation, I identified the problem as being related to the handling of complex objects, particularly those involving dates. Even after simplifying the object structure, the CreateTask function continued to fail.

Introduction In this post, I’ll walk you through how to call Azure AI Search APIs from a M365 Copilot declarative agent without writing any code by using Teams Toolkit. Leveraging OpenAPI specifications, Teams Toolkit enables seamless integration with Azure AI Search, streamlining the development process for Copilot extensibility. Waldek Mastykarz wrote an insightful post on when Azure AI Search can be used, highlighting its ability to provide a more controlled approach to indexing and relevance without the complexity of building a custom engine agent.

Introduction In this post, I’ll walk you through how to call Azure OpenAI APIs from a Copilot declarative agent—without writing any code—by using Teams Toolkit. Leveraging OpenAPI specifications, Teams Toolkit enables seamless integration with Azure OpenAI, streamlining the development process for Copilot extensibility. Step 1: Create and Import an OpenAPI Specification Microsoft provides a pre-built OpenAPI specification for Azure OpenAI, but it’s often broader than needed. To simplify, I generated a targeted OpenAPI spec with Copilot by using the endpoint URL and a sample request body as a prompt.

Introduction This guide walks you through creating a Copilot agent using Teams Toolkit and Microsoft Graph API. By leveraging OpenAPI specifications, Kiota, and Teams Toolkit, you can build a plugin to interact with Microsoft Graph endpoints. I used the blog post Copilot Graph API QnA Plugin by Franck Cornu as inspiration with some variation to apply it to get my ToDo tasks. Plugins for Copilot agents rely on OpenAPI specifications. While the complete Microsoft Graph OpenAPI specification exists, it is a massive file (34MB) and not practical for performance reasons.

Troubleshooting Copilot Agent Teams Toolkit M365Graph Plugin Issues When building a Copilot agent using Teams Toolkit, you may encounter certain errors that can hinder your progress. This blog post highlights common issues and provides solutions to help you resolve them effectively. Common Issues and Fixes 1. name_for_human Exceeds 20 Characters Issue: You may encounter the following error when the name_for_human field in the ai-plugin.json file exceeds 20 characters: name_for_human in PluginManifestDocument has characters beyond the length 20 that MAY be ignored.
