macOS Terminal Skill

Control macOS Terminal.app using AppleScript (osascript).

Opening Windows and Tabs

# New window (empty)
osascript -e 'tell application "Terminal" to do script ""'

# New window running a command
osascript -e 'tell application "Terminal" to do script "echo hello"'

# New tab in frontmost window (via System Events keystroke)
osascript -e 'tell application "System Events" to tell process "Terminal" to keystroke "t" using command down'

Note: There is no native AppleScript command to open a new tab — System Events keystroke is required (needs Accessibility permission).
