screenshot

description

Take a screenshot of the game window (OpenChaos.exe). Use when the user asks to see the game screen, or when you need to see what's currently rendered. Never take screenshots proactively — only when the user explicitly asks or confirms. Trigger when: user says "скрин", "screenshot", "покажи что на экране", "сделай скрин", "что сейчас видно", "скринь", "сфоткай", "покажи экран", or when you suggest taking a screenshot and the user agrees.

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

powershell -c "

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)
