Summary
We’re updating Agent Builder to make creating and configuring agents simpler and more intuitive. New agents will have capabilities enabled by default, providing access similar to Microsoft 365 Copilot. Builders can continue to customize and scope capabilities as needed to support specialized tasks and organizational requirements.
We are also introducing an improved configuration experience to make knowledge setup easier to understand and manage. In addition, the existing “Uploaded Files” label will be renamed to “Attachments.” This is a terminology update only and does not change functionality.
