Implementation Reference

• src/tools/powershell.js:125-154 (handler)

  The main handler function for 'get_system_info' that executes PowerShell commands to gather system details including OS, computer model, memory, and CPU information, parses the JSON output, and returns it in a success/error structure.

  async getSystemInfo() {
    try {
      const command = `
        $os = Get-CimInstance Win32_OperatingSystem
        $cs = Get-CimInstance Win32_ComputerSystem
        $cpu = Get-CimInstance Win32_Processor
        @{
          ComputerName = $cs.Name
          OS = $os.Caption
          Version = $os.Version
          Architecture = $os.OSArchitecture
          Manufacturer = $cs.Manufacturer
          Model = $cs.Model
          TotalMemoryGB = [math]::Round($cs.TotalPhysicalMemory / 1GB, 2)
          CPU = $cpu.Name
          CPUCores = $cpu.NumberOfCores
          CPULogical = $cpu.NumberOfLogicalProcessors
        } | ConvertTo-Json
      `;
  
      const { stdout } = await execAsync(`powershell -Command "${command.replace(/"/g, '\\"')}"`, {
        shell: 'powershell.exe'
      });
  
      const info = JSON.parse(stdout);
      return { success: true, info };
    } catch (error) {
      return { success: false, error: error.message };
    }
  }
