Copilot Studio rebuilds agent workflows with a new AI core
Microsoft announced a rebuilt Copilot Studio on June 9, 2026. The update adds a streamlined authoring experience, a modern AI core, a new agentic orchestrator, workflow designer improvements, agent nodes, and preview support for MCP server-enabled tools. Microsoft says the new experience is generally available worldwide while classic agents and workflows continue to coexist.
Power Apps makers are already being pulled from simple screens and forms into agents, approvals, and workflow handoffs. The old Copilot Studio experience could work, but it made many builders manage topics, tools, and test paths in separate places. The rebuild makes agent and workflow authoring easier to start, but it does not remove the need to test real permissions, Dataverse or SharePoint data access, and failure paths. For non-developer makers, the useful change is a clearer build surface, not permission to skip validation.
Analysis
Before rebuilding an existing assistant, pick one narrow scenario and run it through both the classic and new experience. Compare the generated workflow, tool access, approval points, and error handling before you move a live team process.
