name: dump-ebitengine-screen description: > Use this skill to capture a screenshot of a running Ebitengine app (Guigui, raw Ebitengine, anything that implements ebiten.Game) for visual debugging — for example to verify a layout or rendering fix without asking the user to run the app and paste a screenshot. Works on macOS where screencapture / AppleScript / EBITENGINE_SCREENSHOT_KEY + keystroke-injection tricks tend to fail because the example window doesn't take focus when launched from a sandboxed shell. Use whenever
