Tool Usage Examples

​
Send a Message

const result = await agent.run("Send 'Deployment complete! v2.3.1 is live.' to #deployments");

// The agent calls slack_send_message with:
// { channel: "#deployments", text: "Deployment complete! v2.3.1 is live." }

​
Reply in Thread

const result = await agent.run(
  "Reply to the latest message in #support with " +
  "'Thanks for reporting this. We're looking into it now.'"
);

// The agent calls slack_read_messages to find the latest message,
// then calls slack_reply_thread with:
// {
//   channel: "#support",
//   threadTs: "1709234567.123456",
//   text: "Thanks for reporting this. We're looking into it now."
// }

​
List Channels

const result = await agent.run("What channels do we have for the engineering team?");

// The agent calls slack_list_channels
// Returns: #engineering, #eng-frontend, #eng-backend, #eng-devops, #eng-standup

​
Read Recent Messages

const result = await agent.run("What's been discussed in #product today?");

// The agent calls slack_read_messages with:
// { channel: "#product", limit: 20 }
// Then summarizes the conversation
