What should I check if my UI is not updating during a stream?

Ensure your response Content-Type is set to 'text/event-stream', check for CORS errors, and verify that you are emitting 'text-delta' events.

What event types are supported by assistant-stream?

Supported events include part-start (text, reasoning, tool-call, source, file), text-delta, result, step-start, step-finish, message-finish, and error.

When should I use assistant-stream instead of Vercel AI SDK?

Use assistant-stream when you are building custom backends or protocols. If you are already using the Vercel AI SDK, you should use toUIMessageStreamResponse() instead.

How do I handle tool calls within a stream?

You can use the addToolCallPart method to define a tool call ID and name, then use tool.argsText.append to stream the arguments and tool.setResponse for the final result.
