CPU, RAM, battery, GPU, network, running processes, OS details. Zero external dependencies — uses built-in WMI (Get-CimInstance) and PowerShell. Works on Windows 10/11 with PowerShell 5.1+. ## System Overview ```powershell powershell.exe -NoProfile -Command " $os = Get-CimInstance Win32_OperatingSystem $cs = Get-CimInstance Win32_ComputerSystem $uptime = (Get-Date) - $os.LastBootUpTime Write-Host ('Computer: {0}' -f $cs.Name) Write-Host ('OS: {0} (Build {1})' -f $os.Caption, $os.BuildNumber) Write-Host ('Architecture: {0}' -f $os.OSArchitecture) Write-Host ('User: {0}\{1}' -f $cs.Domain, $env:USERNAME) Write-Host ('Uptime: {0}d {1}h {2}m' -f [int]$uptime.TotalDays, $uptime.Hours, $uptime.Minutes) Write-Host ('Install Date: {0}' -f $os.InstallDate.ToString('yyyy-MM-dd')) " ``` ## CPU Info ```powershell powershell.exe -NoProfile -Command " $cpu = Get-CimInstance Win32_Processor foreach ($c in $cpu) { Write-Host ('CPU: {0}' -f $c.Name.Trim()) Write-Host ('Cores: {0} physical, {1} logical' -f $c.NumberOfCores, $c.NumberOfLogicalProcessors) Write-Host ('Max Clock: {0} MHz' -f $c.MaxClockSpeed) Write-Host ('Current Clock: {0} MHz' -f $c.CurrentClockSpeed) Write-Host ('Load: {0}%' -f $c.LoadPercentage) } " ``` ## CPU Usage (Real-Time) ```powershell powershell.exe -NoProfile -Command " $samples = 3 Write-Host ('Sampling CPU usage ({0} samples)...' -f $samples) for ($i = 1;

" ``` Replace `PROCESS_ID` with the PID from the process list. ## Startup Programs ```powershell powershell.exe -NoProfile -Command " Get-CimInstance Win32_StartupCommand | Select-Object Name, Command, Location | Format-Table -AutoSize " ``` ## Installed Software ```powershell powershell.exe -NoProfile -Command " Get-CimInstance Win32_Product | Select-Object Name, Version, Vendor | Sort-Object Name | Format-Table -AutoSize " ``` Note: `Win32_Product` can be slow. For a faster check of a specific program, use `winget list PROGRAM_NAME` (via the `winget` skill). ## Environment Variables ```powershell powershell.exe -NoProfile -Command " Get-ChildItem Env: | Sort-Object Name | Format-Table Name, Value -AutoSize " ``` ### Check a Specific Variable ```powershell powershell.exe -NoProfile -Command " Write-Host ('VAR_NAME = {0}' -f $env:VAR_NAME) " ``` ## Common Workflows ### System health check ``` 1. win-sysinfo: system overview (uptime, OS version) 2. win-sysinfo: CPU usage + memory usage 3. win-sysinfo: battery status 4. win-files: list drives (disk space) 5. Report any issues found ``` ### Diagnose slow machine ``` 1. win-sysinfo: top processes by CPU 2. win-sysinfo: top processes by memory 3. win-sysinfo: memory usage percentage 4. Identify resource hogs and suggest actions ``` ### Network troubleshooting ``` 1. win-sysinfo: network adapters and IP config 2. win-sysinfo: internet connectivity test 3. Report connection status and suggest fixes ``` ### Pre-meeting check ``` 1. win-sysinfo: battery level 2. win-sysinfo: internet connectivity 3. win-sysinfo: CPU/memory headroom 4. Alert if any issues before joining ``` ## Notes - Fully offline — no API keys, no network (except connectivity test), no external dependencies. - Uses WMI (`Get-CimInstance`) and built-in PowerShell cmdlets. - CPU load percentage is a snapshot — use the real-time sampling command for trends. - Battery info only available on laptops/tablets — desktops will show "No battery detected." - `Win32_Product` is slow (~30s) — prefer `winget list` for faster software queries. - NPU detection uses PnP device name matching — works for Intel AI Boost, may need adjustment for other NPU brands. - For disk space info, use the `win-files` skill's List Drives command. - Process kill requires appropriate permissions — elevated processes may need admin PowerShell. - GPU VRAM via `Win32_VideoController.AdapterRAM` is a 32-bit field (max ~4 GB). For GPUs with >4 GB VRAM, the reported value will be incorrect. Use `dxdiag` or GPU-specific tools for accurate VRAM.
