Implementation Reference

• src/tools/mouse-keyboard.js:188-200 (handler)

  The core handler function implementing get_screen_size tool logic, retrieving screen size via robotjs or fallback default values.

  getScreenSize() {
    try {
      if (this.robotAvailable) {
        const size = this.robot.getScreenSize();
        return { success: true, width: size.width, height: size.height };
      } else {
        // 备用方法：使用 PowerShell
        return { success: true, width: 1920, height: 1080, note: '使用默认值' };
      }
    } catch (error) {
      return { success: false, error: error.message };
    }
  }

• src/tools/mouse-keyboard.js:82-89 (schema)

  Schema definition for the get_screen_size tool, specifying name, description, and empty input schema.

  {
    name: 'get_screen_size',
    description: '获取屏幕尺寸',
    inputSchema: {
      type: 'object',
      properties: {},
    },
  },

• src/tools/mouse-keyboard.js:118-119 (registration)

  Registration and dispatch of get_screen_size in the executeTool method's switch statement.

  case 'get_screen_size':
    return this.getScreenSize();

• src/tools/mouse-keyboard.js:94-96 (registration)

  Tool name registered in the canHandle method's supported tools array.

  const tools = ['move_mouse', 'mouse_click', 'type_text', 'press_key', 
                 'get_mouse_position', 'get_screen_size'];
  return tools.includes(toolName);

• src/tools/mouse-keyboard.js:100-105 (helper)

  Helper condition in executeTool allowing get_screen_size to run without robotjs dependency.

  if (!this.robotAvailable && name !== 'get_screen_size') {
    return { 
      success: false, 
      error: 'robotjs 未安装。请运行: npm install robotjs（需要 Windows Build Tools）' 
    };
  }
