Chat SDK adds native Slack agent support

You can now build native Slack agents with Chat SDK's Slack adapter.

The adapter supports the full Slack agent messaging experience, from agent conversations in the Messages tab to suggested prompts, rotating status messages, token-by-token streamed replies, and native feedback buttons.

import { Chat } from "chat";
import { createSlackAdapter } from "@chat-adapter/slack";

const bot = new Chat({
  userName: "mybot",
  adapters: {
    slack: createSlackAdapter({
      agentView: true,
      suggestedPrompts: {
        title: "Welcome! What can I do for you?",
        prompts: [
          { title: "Catch me up", message: "What did I miss today?" },
          { title: "Draft a message", message: "Help me draft a message" },
        ],
      },
      loadingMessages: ["Thinking...", "Digging through the archives..."],
      feedbackButtons: true,
    }),
  },
});

Here's what the adapter gives you:

• Suggested prompts, per thread: Pass a static payload or an async resolver that receives the thread context, including what the user is currently viewing under agent_view. Prompts are pinned automatically whenever an agent thread opens.

• Native streaming with a fallback: Streamed replies render token-by-token via Slack's streaming API, including task and plan cards. If a workspace doesn't support streaming (e.g., GovSlack), the adapter switches to post-and-edit mid-stream without losing content.

• Built-in feedback: Set feedbackButtons: true and every streamed reply ends with Slack's native thumbs-up and thumbs-down buttons. Clicks dispatch through the regular bot.onAction flow with a positive or negative value.

One thing to know: under agent_view, Slack threads each user message individually, so channel history only returns the user's side of a DM. Use Chat SDK transcripts to build AI conversation history instead.
