    if (!channel || typeof channel !== "string") {
      throw new Error("channel 인자가 필요합니다.");
    }
  
    const config = this.loadConfig();
    const channelExists = config.webhooks.some((w) => w.channel === channel);
  
    if (!channelExists) {
      throw new Error(`등록되지 않은 채널입니다: ${channel}`);
    }
  
    config.default_channel = channel;
    this.saveConfig(config);
  
    return {
      content: [
        {
          type: "text",
