Integrating VoltAgent with Chat SDK

Use Chat SDK for Slack transport (webhooks, thread subscriptions, interactive actions) and VoltAgent for AI reasoning/tool calling.

Quick Start

npm create voltagent-app@latest -- --example with-chat-sdk
cd with-chat-sdk
pnpm install
pnpm dev

The example exposes a webhook endpoint at /api/webhooks/slack and expects:

• OPENAI_API_KEY
• SLACK_BOT_TOKEN
• SLACK_SIGNING_SECRET
• REDIS_URL

Expose your local webhook with Volt Tunnel:

pnpm volt tunnel 3000

Minimal Code Example

lib/bot.ts

import { createSlackAdapter } from "@chat-adapter/slack";
import { createRedisState } from "@chat-adapter/state-redis";
import { Chat } from "chat";
import { slackAssistantAgent } from "./agent";

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

bot.onNewMention(async (thread) => {
  await thread.subscribe();
  await thread.post("I am subscribed to this thread. Send a follow-up message.");
});

bot.onSubscribedMessage(async (thread, message) => {
  const input = message.text?.trim();
  if (!input) return;

  const { text } = await slackAssistantAgent.generateText(
    `Respond as a concise teammate.\nMessage: ${input}`
  );

  await thread.post(text || "Could not generate a response.");
});

This gives you the core integration pattern: Chat SDK handles Slack transport, VoltAgent handles reasoning.
