Typical Workflow

1. Read the screen to understand what's visible:

   python3 skills/desktop-control/scripts/screen.py read-ui
   

2. Identify targets from the accessibility tree output
3. Interact using mouse/keyboard:

   python3 skills/desktop-control/scripts/mouse.py click --x 500 --y 300
   python3 skills/desktop-control/scripts/keyboard.py type --text "search query"
   python3 skills/desktop-control/scripts/keyboard.py press --key enter
   

4. Verify by reading the screen again

Example

click on the search bar
type "hello" into the text field
press command+s to save
what's on the screen right now
read the UI elements of the current window
move the mouse to the center of the screen
scroll down in this window
