Implementation Reference

src/index.ts:520-554 (handler)

The handler function that implements the get_last_image_info tool. It checks if a last image path exists, verifies the file, retrieves stats, and returns formatted information or appropriate messages if no image or file missing.

private async getLastImageInfo(): Promise<CallToolResult> {
  if (!this.lastImagePath) {
    return {
      content: [
        {
          type: "text",
          text: "📷 No previous image found.\n\nPlease generate or edit an image first, then this command will show information about your last image.",
        },
      ],
    };
  }

  // 检查文件是否存在
  try {
    await fs.access(this.lastImagePath);
    const stats = await fs.stat(this.lastImagePath);
    
    return {
      content: [
        {
          type: "text",
          text: `📷 Last Image Information:\n\nPath: ${this.lastImagePath}\nFile Size: ${Math.round(stats.size / 1024)} KB\nLast Modified: ${stats.mtime.toLocaleString()}\n\n💡 Use continue_editing to make further changes to this image.`,
        },
      ],
    };
  } catch {
    return {
      content: [
        {
          type: "text",
          text: `📷 Last Image Information:\n\nPath: ${this.lastImagePath}\nStatus: ❌ File not found\n\n💡 The image file may have been moved or deleted. Please generate a new image.`,
        },
      ],
    };
  }
