@alep I guess your issue is resolved?

if no start message is provided for a tool, it defaults to using random filler messages like "Hold on a sec", "One moment", etc. Here are two approaches to solve this: 1. Set Empty Messages Array You can explicitly set an empty messages array for your tool to prevent any default messages:

javascript
const tool = {
  type: "function",
  async: false,
  messages: [], // This will override the default messages
  function: {
    // your function definition
  }
};

2. Use Async Tool If you don't need an immediate response from the tool, you can set it as async which will prevent start messages from being spoken:

javascript
const tool = {
  type: "function", 
  async: true, // Async tools don't trigger start messages
  function: {
    // your function definition
  }
};

The second approach is recommended if you're just polling and don't need synchronous responses, as it's explicitly mentioned.
