ebiten

Use this skill to run an Ebitengine app (anything implementing ebiten.Game) headlessly and programmatically — no visible window and no changes to the app's source — to test, debug, screenshot, or otherwise exercise it. It launches the app as a vmhost guest, drives it through its ticks faster than real time, injects keyboard / mouse / touch / gamepad / text input, reads the rendered frame back as pixels to assert on or dump as a PNG, and observes the audio the app plays. Use when you need input injection, deterministic multi-tick runs, golden-image checks, or audio assertions — for example to reproduce an input-dependent bug, verify behavior after a sequence of clicks or key presses, check that the right sound plays, capture a single rendered frame, or let an AI agent drive an app end-to-end.
