This is a great improvement to manually updating and generating JSON and YAML yourself which is not the best experience.

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 Microsoft 365 Agents Toolkit. Leveraging OpenAPI specifications, Microsoft 365 Agents Toolkit (previously known as 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.
