Cua control primitives

These tools target the active Cua sandbox (or localhost when in that mode). Always take a cua_screenshot first when you need coordinates; never guess pixel positions blindly.

Coordinates

Coordinates are in pixels from the top-left of the target display. The default sandbox display is 1024x768 (XGA) which matches Anthropic's recommended computer-use resolution. Cua handles Retina/HiDPI scaling internally on macOS.
