Programmatic API

import {

  listSessions,
  startPolling,
  createChannel,
  listChannels,
  joinChannel,
} from "@hasna/conversations";

// Send a direct message
const msg = sendMessage({
  from: "my-agent",
  to: "claude-code",
  content: "Hello!",
});

// Read messages
const messages = readMessages({ to: "my-agent", unread_only: true });

// Poll for new messages (200ms interval)
const { stop } = startPolling({
  to_agent: "my-agent",
  on_messages: (msgs) => console.log("New:", msgs),
});

// Channels
createChannel("deploys", "my-agent", "Deploy notifications");
joinChannel("deploys", "claude-code");
sendMessage({
  from: "my-agent",
  to: "deploys",

});
const channelMsgs = readMessages({ channel: "deploys" });
