AG-UI protocol event structures, types, and integration guide for streaming agent responses. Use when implementing streaming UI, consuming AG-UI events from a backend agent, understanding event flow, building SSE endpoints that emit AG-UI events, handling tool call events, rendering reasoning/thinking events, or debugging event flow/ordering. Do NOT use for generic SSE endpoints that don't carry AG-UI events, or for MCP (tool-calling) or A2A (agent-to-agent) protocol integration — AG-UI is the agent-to-user layer only.

# AG-UI Protocol Events Reference Quick-reference for the AG-UI (Agent-User Interaction) protocol streaming events. ## When to Use This Skill * Building a frontend that consumes streaming agent responses * Implementing a backend endpoint that serves AG-UI events * Debugging event ordering or missing events in streaming flows * Understanding the event lifecycle for tool calls, text messages, or reasoning ## Dependencies | Package | Role | Required | | --- | --- | --- | | `ag-ui-protocol` (PyPI) | Python event classes (Pydantic v2) — backend emission | Yes, for a Python backend | | `pydantic>=2.11.2` | Required by `ag-ui-protocol` for model validation/serialization | Yes (transitive) | | `@ag-ui/core` (npm) | TypeScript event types/enums — canonical type source for frontend | Yes, for a TS/JS frontend | | `@ag-ui/client` | SSE consumer / agent runner, depends on `@ag-ui/core` | Recommended | | `@ag-ui/react` | React hooks (`useAgentStream`, `useAgentState`) | Optional | | `sse-starlette` | Alternative FastAPI SSE response wrapper (see backend-guide.md) | Optional | | `fast-json-patch` (npm) | Applying `STATE_DELTA`/`ACTIVITY_DELTA` RFC 6902 patches on the frontend | Optional | See "Verified against" below for exact versions this skill was checked against. ## Official References | Resource | Link | | :--- | :--- | | **AG-UI Protocol (GitHub)** | https://github.com/ag-ui-protocol/ag-ui | | **AG-UI Documentation** | https://docs.ag-ui.com | | **AG-UI Python SDK** | https:/
