get_screenshot
Capture a low-resolution screenshot for AI visual analysis, returning the file path and an optional scale factor for coordinate adjustment when downscaled.
Instructions
Capture a fast, low-quality screenshot for LLM visual analysis. Returns the file path to the saved image. The image may be downscaled by an integer factor so its long edge stays ≤ 2000px; when that happens the response includes a scale factor — multiply any coordinates you read off the image by that factor before using them in device actions (tap, swipe, drag, long-press, etc.). UI tree coordinates are already in device pixels, do not scale those. Use this for AI/LLM processing only — for full-quality screenshots use save_screenshot instead.
