We are announcing the tool accuracy grader in Copilot Studio. This feature reached general availability on October 15, 2026. How does this affect me? This feature enables you to evaluate whether your agents selected the correct tools or actions and used them with the expected inputs for a given user request. This helps you to identify execution issues earlier, reduce manual trace inspection, and increase confidence that agents are performing actions correctly and reliably. What action do I need to take? This message is for awareness, and no action is required.
