Os Use

This is a comprehensive cross-platform automation toolkit that gives Claude direct control over your desktop. It handles screenshots, visual recognition with OpenCV, mouse and keyboard control via pyautogui, and window management through AppleScript on macOS or pywinauto on Windows. You'd reach for this when you need to automate repetitive UI tasks, run automated testing without Selenium, or extract data from applications without APIs. The implementation is mature with proper error handling patterns and retry logic built in. Fair warning: you'll need to grant Accessibility and Screen Recording permissions on macOS, and some operations require admin rights on Windows. It's genuinely useful for desktop automation but expect to do some permission wrangling on first setup.
