Cua Driver now supports Windows background computer-use for agents such as Claude Code, Codex, and Hermes. The driver provides window pixels, UIA/MSAA accessibility trees, and an action layer for clicks, typing, scrolling, values, and verification, using a synthetic cursor separate from the user's physical pointer. It routes between different backends (e.g., PrintWindow, Windows.Graphics.Capture, UI Automation, MSAA, PostMessage, SendInput) depending on the target app type and action.
