+# @ag-ui/proto
+
+Protocol Buffer encoding/decoding for **Agent-User Interaction (AG-UI) Protocol** events.
+
+`@ag-ui/proto` provides high-performance binary serialization of AG-UI events using Protocol Buffers. It includes generated TypeScript definitions and utilities for converting between AG-UI's JSON event format and compact binary representation.
+
+## Installation
+
+```bash
+npm install @ag-ui/proto
+pnpm add @ag-ui/proto
+yarn add @ag-ui/proto
+```
+
+## Features
+
+- ⚡ **High performance** – Binary protobuf encoding for minimal bandwidth usage
+- 🔄 **Round-trip safety** – Lossless conversion between JSON and binary formats
+- 📋 **Generated types** – Auto-generated TypeScript definitions from `.proto` schemas
+- 🔧 **Length-prefixed** – Standard 4-byte length headers for streaming protocols
+
+## Quick example
+
+```ts
+import { encode, decode, AGUI_MEDIA_TYPE } from "@ag-ui/proto";
+import { EventType } from "@ag-ui/core";
+
+const event = {
+  type: EventType.TEXT_MESSAGE_START,
+  messageId: "msg_123",
+  role: "assistant",
+};
+
+// Encode to binary protobuf format
+const encoded = encode(event);
+
+// Decode back to AG-UI event
+const decoded = decode(encoded);
+console.log(decoded); // Original event object
+```
