+# @ag-ui/client
+
+Client SDK for connecting to **Agent-User Interaction (AG-UI) Protocol** servers.
+
+`@ag-ui/client` provides agent implementations that handle the full lifecycle of AG-UI communication: connecting to servers, processing streaming events, managing state mutations, and providing reactive subscriber hooks.
+
+## Installation
+
+```bash
+npm install @ag-ui/client
+pnpm add @ag-ui/client
+yarn add @ag-ui/client
+```
+
+## Features
+
+- 🔗 **HTTP connectivity** – `HttpAgent` for direct server connections with SSE/protobuf support
+- 🏗️ **Custom agents** – `AbstractAgent` base class for building your own transport layer
+- 📡 **Event streaming** – Full AG-UI event processing with validation and transformation
+- 🔄 **State management** – Automatic message/state tracking with reactive updates
+- 🪝 **Subscriber system** – Middleware-style hooks for logging, persistence, and custom logic
+- 🎯 **Middleware support** – Transform and filter events with function or class-based middleware
+
+## Quick example
+
+```ts
+import { HttpAgent } from "@ag-ui/client";
+
+const agent = new HttpAgent({
+  url: "https://api.example.com/agent",
+  headers: { Authorization: "Bearer token" },
+});
+
+const result = await agent.runAgent({
+  messages: [{ role: "user", content: "Hello!" }],
+});
+
+console.log(result.newMessages);
+```
+
+## Using Middleware
+
+```ts
+import { HttpAgent, FilterToolCallsMiddleware } from "@ag-ui/client";
+
+const agent = new HttpAgent({
+  url: "https://api.example.com/agent",
+});
+
+// Add middleware to transform or filter events
+agent.use(
+  // Function middleware for logging
+  (input, next) => {
+    console.log("Starting run:", input.runId);
+    return next.run(input);
+  },
+
+  // Class middleware for filtering tool calls
+  new FilterToolCallsMiddleware({
+    allowedToolCalls: ["search", "calculate"]
+  })
+);
+
+await agent.runAgent();
+```

+# @ag-ui/core
+
+TypeScript definitions & runtime schemas for the **Agent-User Interaction (AG-UI) Protocol**.
+
+`@ag-ui/core` delivers the strongly-typed building blocks that every other AG-UI package is built on: message & state models, run inputs and the full set of streaming event types.
+
+## Installation
+
+```bash
+npm install @ag-ui/core
+pnpm add @ag-ui/core
+yarn add @ag-ui/core
+```
+
+## Features
+
+- 🧩 **Typed data models** – `Message`, `Tool`, `Context`, `RunAgentInput`, `State` …
+- 🔄 **Streaming events** – 16 core event kinds covering assistant messages, tool calls, state updates and run lifecycle.
+- ✅ **Runtime validation** – schemas catch malformed payloads early.
+- 🚀 **Framework-agnostic** – works in Node.js, browsers and any agent framework that can emit JSON.
+
+## Quick example
+
+```ts
+import { EventSchemas, EventType } from "@ag-ui/core";
+
+// Validate an incoming event
+EventSchemas.parse({
+  type: EventType.TEXT_MESSAGE_CONTENT,
+  messageId: "msg_123",
+  delta: "Hello, world!",
+});
+```

+# @ag-ui/encoder
+
+Event encoding utilities for the **Agent-User Interaction (AG-UI) Protocol**.
+
+`@ag-ui/encoder` handles content negotiation and format encoding for AG-UI events. It automatically chooses between Server-Sent Events (JSON) and Protocol Buffers based on client `Accept` headers, ensuring optimal transport efficiency.
+
+## Installation
+
+```bash
+npm install @ag-ui/encoder
+pnpm add @ag-ui/encoder
+yarn add @ag-ui/encoder
+```
+
+## Features
+
+- 🎯 **Content negotiation** – Automatic format selection based on `Accept` headers
+- 📦 **Dual encoding** – SSE (JSON) and Protocol Buffer support
+- ⚡ **Efficient binary** – Length-prefixed protobuf encoding for high-throughput scenarios
+- 🔄 **Seamless fallback** – Graceful degradation to SSE when protobuf isn't supported
+
+## Quick example
+
+```ts
+import { EventEncoder } from "@ag-ui/encoder";
+import { EventType } from "@ag-ui/core";
+
+const encoder = new EventEncoder({
+  accept: "application/vnd.ag-ui.event+proto, text/event-stream",
+});
+
+const event = {
+  type: EventType.TEXT_MESSAGE_CONTENT,
+  messageId: "msg_123",
+  delta: "Hello, world!",
+};
+
+// Returns protobuf-encoded binary data
+const encoded = encoder.encodeBinary(event);
+```

+# @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
+```
