AG-UI

SharpOMatic supports AG-UI so browser and app clients can invoke workflows through a standard server-sent events endpoint. Use this section when you want to test workflows over the protocol, build a chat client, or understand how SharpOMatic maps workflow stream events into AG-UI events.

What is AG-UI?

AG-UI is the Agent-User Interaction Protocol. It is an open, event-based protocol for connecting user-facing applications to agentic backends. An AG-UI client sends a run request, such as RunAgentInput, and receives a stream of structured events such as lifecycle, text message, tool call, state, activity, and custom events.

The benefit is that a frontend can talk to different agent or workflow backends through a common contract instead of one-off request and streaming formats. For SharpOMatic, that means a client such as Sharpy can call a workflow, render streamed model output, handle frontend tool calls, and keep conversation state aligned over the AG-UI protocol.
