Today we’re announcing the public preview of the Microsoft 365 Copilot Agent Evaluations tool. The Agent Evaluations CLI tool helps developers measure and improve the quality of agents they build for Microsoft 365 Copilot. The tool provides a command-line interface that sends prompts to a deployed agent, captures responses, and scores them with the help of Azure OpenAI LLM models. It produces structured reports developers can use in their inner loop of development and in CI/CD pipelines.
