System Documentation

What problem does it solve?

It prevents broken or inconsistent assistant-ui streaming by guiding you through the correct streaming formats, encoders/decoders, and event shapes used to deliver text, tool calls, reasoning, and results to the UI.

Core Features & Use Cases

  • Protocol selection for backends: Choose between AI SDK Data Stream helpers and assistant-stream for custom streaming backends.
  • Correct wire formats and event decoding: Understand and implement Data Stream SSE and assistant-ui’s native Assistant Transport so the client renders updates properly.
  • Tool-call streaming support: Emit tool-call parts with deterministic args streaming and attach tool results to the right tool call.

Quick Start

Implement a streaming endpoint that returns assistant-ui compatible SSE by using createAssistantStreamResponse and closing the stream after emitting text, optional tool-call parts, and final results.
