100-word summary
Microsoft just open-sourced a way to stress-test AI agents before they embarrass you in front of customers. The new kit runs your bot through realistic email and calendar scenarios, then scores it on everything from following rules to not sounding like a jerk. You can pit agents built on different models against each other using identical tests, which finally answers the "is this actually better?" question before you ship. It checks whether your agent calls the right tools, respects policies, and produces coherent answers. The whole point: stop guessing whether your AI is ready and start measuring it against the chaos of real Microsoft 365 workflows.
