screenshot

# Screenshot — capture the game window ## When to use - User **explicitly** says "сделай скрин", "screenshot", "скринь" — just do it - You **think** a screenshot would help but user didn't ask — ask first: "Сделать скриншот?" - **Never take screenshots without permission** ## Capture command ```bash powershell -c " Add-Type -AssemblyName System.Windows.Forms Add-Type -AssemblyName System.Drawing Add-Type @' using System; using System.Runtime.InteropServices; public class ScrCap { [DllImport(\"user32.dll\")] public static extern bool SetProcessDPIAware(); [DllImport(\"user32.dll\")] public static extern bool IsIconic(IntPtr hWnd); [DllImport(\"user32.dll\")] public static extern bool ShowWindow(IntPtr hWnd, int nCmdShow); [DllImport(\"user32.dll\")] public static extern bool SetForegroundWindow(IntPtr hWnd); [DllImport(\"dwmapi.dll\")] public static extern int DwmGetWindowAttribute(IntPtr hwnd, int attr, out RECT rect, int size); [StructLayout(LayoutKind.Sequential)] public struct RECT { public int Left, Top, Right, Bottom; } } '@ [ScrCap]::SetProcessDPIAware() | Out-Null \$proc = Get-Process OpenChaos -ErrorAction SilentlyContinue if (-not \$proc) { Write-Host 'OpenChaos not running'; exit 1 } \$hwnd = \$proc.MainWindowHandle if ([ScrCap]::IsIconic(\$hwnd)) { [ScrCap]::ShowWindow(\$hwnd, 9) | Out-Null } [ScrCap]::SetForegroundWindow(\$hwnd) | Out-Null Start-Sleep -Milliseconds 300 \$rect = New-Object ScrCap+RECT [ScrCap]::DwmGetWindowAttribute(\$hwnd, 9, [ref]\$rect, [Runtime.InteropServices.Marshal]::SizeOf(\$rect)) | Out-Null \$w = \$rect.Right - \$rect.Left; \$h = \$rect.Bottom - \$rect.Top \$bmp = New-Object System.Drawing.Bitmap(\$w, \$h) \$g = [System.Drawing.Graphics]::FromImage(\$bmp) \$g.CopyFromScreen(\$rect.Left, \$rect.Top, 0, 0, (New-Object System.Drawing.Size(\$w, \$h))) \$g.Dispose() \$stream = [System.IO.File]::Create('C:\WORK\OpenChaos\_CLAUDE_SCREEN.png') \$bmp.Save(\$stream, [System.Drawing.Imaging.ImageFormat]::Png) \$stream.Close(); \$bmp.Dispose() Write-Host 'OK' " 2>&1 ``` **If PowerShell complains about duplicate type `ScrCap`** — change `ScrCap` to `ScrCap2`, `ScrCap3`, etc. (types persist per PowerShell session). ## After capturing 1. Read the screenshot: `Read` tool on `c:\WORK\OpenChaos\_CLAUDE_SCREEN.png` 2. Show the user a clickable link: `[screenshot](_CLAUDE_SCREEN.png)` 3. Describe what you see 4. File is overwritten each time, gitignored ## Technical details - `SetProcessDPIAware()` — required for correct coordinates on scaled displays - `DwmGetWindowAttribute(hwnd, 9)` — real window bounds without shadow - `IsIconic` + `ShowWindow(9)` — restores if minimized - `CopyFromScreen` — works with OpenGL (unlike PrintWindow)
