Google and CopilotKit publish an A2UI bidirectional app guide

On October 29, Google’s A2UI team and CopilotKit published an official guide to connecting AG-UI agents to A2UI interfaces. Unlike the earlier A2UI Express announcement, it covers CopilotKit catalogs and renderers, Zod property validation, and returning user input to update the same surfaceId. It is not a new SDK release announcement. Developers can define trusted components and input checks, then verify generation retries and failure handling in their own apps.
