# Chat SDK

[![Agent Stack](https://img.shields.io/badge/Agent%20Stack-000?style=flat-square&logo=vercel&logoColor=FFF&labelColor=000&color=000)](https://vercel.com/kb/agent-stack)

Unified TypeScript SDK for building chat bots across Slack, Microsoft Teams, Google Chat, Discord, Telegram, GitHub, Linear, WhatsApp, and more. **Write your bot logic once, deploy everywhere.**

## Installation

```bash
npm i chat
```

Install one or more adapters for your platforms:

```bash
npm install @chat-adapter/slack @chat-adapter/teams @chat-adapter/gchat
```

## CLI

Scaffold a minimal Next.js bot app with `create-chat-sdk`:

```bash
npx create-chat-sdk@latest my-bot
```

The CLI generates your `Chat` configuration, webhook route, `.env.example` file, dependencies, and optional Web adapter route from the adapter catalog. See the [CLI docs](https://chat-sdk.dev/docs/create-chat-sdk) for options and non-interactive usage.

## Usage

```typescript
import { Chat } from "chat";
import { createSlackAdapter } from "@chat-adapter/slack";
import { createRedisState } from "@chat-adapter/state-redis";

const bot = new Chat({
  userName: "mybot",
  adapters: {
    slack: createSlackAdapter(),
  },
  state: createRedisState(),
});

bot.onNewMention(async (thread) => {
  await thread.subscribe();
  await thread.post("Hello! I'm listening to this thread.");
});

bot.onSubscribedMessage(async (thread, message) => {
  await thread.post(`You said: ${message.text}`);
});
```

See the [Getting Started guide](https://chat-sdk.dev/docs/getting-started) for a full walkthrough.

## AI Coding Agents

If you use an AI coding agent such as OpenAI Codex, Claude Code, or Cursor, install the Chat SDK skill so it knows the SDK APIs, adapter patterns, and project conventions before writing code.

```bash
npx skills add vercel/chat
```

The skill references bundled documentation in `node_modules/chat/docs`, plus adapter guides and starter templates in the published package.

You can also install the [Vercel Plugin](https://vercel.com/plugin) for a broader agent toolkit. It includes the Chat SDK skill alongside specialist agents, slash commands, and more:

```bash
npx plugins add vercel/vercel-plugin
```

For agent-readable documentation, see [chat-sdk.dev/llms.txt](https://chat-sdk.dev/llms.txt) (page index) or [chat-sdk.dev/llms-full.txt](https://chat-sdk.dev/llms-full.txt) (full text).

## Documentation

Full documentation is available at [chat-sdk.dev/docs](https://chat-sdk.dev/docs) and guides are available in the [Vercel Knowledge Base](https://vercel.com/kb/chat-sdk).
