Minor Changes

1fbce32: feat: add thinking steps support to streaming methods

chat.appendStream, chat.startStream, and chat.stopStream now accept a chunks parameter for streaming structured content including markdown text, plan updates, and task updates.

Related PRs:

#2467 - accept chunks as arguments to chat.{start,append,stop}Stream methods
#2470 - accept chunks as arguments to chat stream helper
#2479 - add task display mode option to start of chat streams
#2481 - export the chat streamer and related options from the package

Example

const stream = new ChatStreamer(client, client.logger, {
  channel: CHANNEL_ID,
  thread_ts: threadTs,
});

await stream.append({
  chunks: [
    {
      type: "markdown_text",
      text: "**Hello!** I am starting to process your request...\n\n",
    },
  ],
});

await stream.append({
  chunks: [
    {
      type: "plan_update",
      title: "Processing tasks...",
    },
    {
      type: "task_update",
      id: "task-1",
      title: "Fetching data from API",
      status: "complete",
      output: "Successfully retrieved 42 records",
    },
  ],
});

await stream.stop({
  chunks: [
    {
      type: "markdown_text",
      text: "\n\n---\n\n✅ **All tasks completed successfully!**\n",
    },
  ],
});
