What this skill does

This skill lets the agent control the local Ubuntu VM desktop:

• Move the mouse to a given coordinate
• Click / right-click / double-click
• Drag from one point to another
• Scroll at a given location
• Type text
• Trigger common hotkeys (copy / paste / select all / undo / redo / address bar / refresh)
• Press single keys like Enter / Esc / Tab reliably
• Focus target windows by title before actions
• Probe current active window + mouse position (focus-probe)
• Retry click around a base point to handle small offset errors (click-retry)
• Take full-screen screenshots and save them to disk

All commands are executed via this Python script and virtualenv:

• Script: /home/moderlick/tools/screen_tool.py
• Python: /home/moderlick/tools/screen-env/.venv/bin/python

Always call it like:

/home/moderlick/tools/screen-env/.venv/bin/python /home/moderlick/tools/screen_tool.py <subcommand> [options...]

Session note:

• Prefer Xorg (x11) session for reliable mouse/keyboard control.
• Under Wayland, pyautogui input simulation may fail due to compositor security restrictions.

Move the mouse

/home/moderlick/tools/screen-env/.venv/bin/python /home/moderlick/tools/screen_tool.py move --position 255,255

Click

/home/moderlick/tools/screen-env/.venv/bin/python /home/moderlick/tools/screen_tool.py click --position 400,300
/home/moderlick/tools/screen-env/.venv/bin/python /home/moderlick/tools/screen_tool.py click --position 400,300 --right
/home/moderlick/tools/screen-env/.venv/bin/python /home/moderlick/tools/screen_tool.py click --position 400,300 --double

Drag

/home/moderlick/tools/screen-env/.venv/bin/python /home/moderlick/tools/screen_tool.py drag --start 100,100 --end 600,400 --duration 0.8

Scroll

/home/moderlick/tools/screen-env/.venv/bin/python /home/moderlick/tools/screen_tool.py scroll --position 800,400 --amount -500

Type text

/home/moderlick/tools/screen-env/.venv/bin/python /home/moderlick/tools/screen_tool.py type --text "Hello from OpenClaw"

Hotkeys

/home/moderlick/tools/screen-env/.venv/bin/python /home/moderlick/tools/screen_tool.py hotkey --combo copy
/home/moderlick/tools/screen-env/.venv/bin/python /home/moderlick/tools/screen_tool.py hotkey --combo address_bar

Press single key

/home/moderlick/tools/screen-env/.venv/bin/python /home/moderlick/tools/screen_tool.py press --key enter
/home/moderlick/tools/screen-env/.venv/bin/python /home/moderlick/tools/screen_tool.py press --key esc

Focus window

/home/moderlick/tools/screen-env/.venv/bin/python /home/moderlick/tools/screen_tool.py focus --name "Firefox|火狐"

Focus probe (check active window + mouse)

/home/moderlick/tools/screen-env/.venv/bin/python /home/moderlick/tools/screen_tool.py focus-probe

Click retry (small-offset compensation)

/home/moderlick/tools/screen-env/.venv/bin/python /home/moderlick/tools/screen_tool.py click-retry --position 1148,768 --radius 30 --step 8 --retries 5

Recommended web workflow:

1. focus Firefox
2. focus-probe
3. click-retry on target input area
4. type text
5. press enter
