# windows-screenshot
Capture a visible Windows app window as a PNG and return the saved path.
## When to use
Use this skill when the user asks for a screenshot of a running Windows app.
Typical trigger phrases:
- "screenshot the app"
- "grab a screenshot of the Windows app"
- "capture the Flutter window"
- "show me the VS Code window screenshot"
Do not use this skill for browser pages. Use the browser screenshot tool instead.
## How to invoke
```powershell
powershell -NoProfile -ExecutionPolicy Bypass -File "<skill-folder>\capture.ps1" -Match "<window-title>"
```
Replace `<skill-folder>` with the folder containing this `SKILL.md` file.
Optional flags:
- `-OutDir "C:/some/dir"`
- `-WaitMs 500`
## Output Format
- The last printed line is the full PNG path.
- Other messages print before it.
- Exit codes:
- `0` success
- `2` no match
- `3` `GetWindowRect` failed
- `4` zero-size window
- `5` `PrintWindow` failed
## Safety Rules
- Do not read PNG bytes into chat unless user asks to inspect image.
- If multiple windows match, narrow with a more specific `-Match` value.
## Why this skill saves tokens
- Saves the display-scale and window-capture steps in one place.
- Returns one path line.
- Avoids repeating fixes for common capture problems.
