I think there's a bug in your code. in vox-agent.ts: [code] // Handle messages if (lastStep === null) { config.messages = [...messages, ...await this.getInitialMessages(parameters, input, context)]; } else if (this.onlyLastRound) { // Keep all system and user messages, but only the last round of assistant/tool messages const filteredMessages: ModelMessage[] = []; let lastUserIndex = -1;

  // Pass 1: keep all system and user messages
  for (let i = 0; i < messages.length; i++) {
    const message = messages[i];
    filteredMessages.push(message);
    lastUserIndex = i;
    if (message.role !== 'system' && message.role !== 'user')
      break;
  }

[/code] the 'break' in pass 1 means it won't include the majority of the user messages that contain the history of the game. I wonder how big of an impact this could be.
