macos-background-cua-skill

Control and automate macOS applications (click, type, scroll, screenshot) without activating the window or stealing focus — the target app stays in the background. Use whenever the user wants to script a macOS app, drive UI from the command line or Python, send clicks/keys to a specific window, capture a specific window's screenshot (even if it's off-screen or occluded), build a computer-use agent targeting macOS, or automate a background app while they keep working in the foreground. Triggers on phrases like "control a Mac app from Python / shell", "click in this app without focusing it", "screenshot a window", "background CUA on macOS", "automate Messages / Mail / Xcode / any macOS app", "send events to a window", or references to Accessibility API + CGEventPostToPid automation.
