- agent-browser click @ref (click element)
- agent-browser fill @ref "text" (clear and type)
- agent-browser type @ref "text" (type without clearing)
- agent-browser select @ref "option" (select dropdown)
- agent-browser screenshot (screenshot to temp dir)
- agent-browser screenshot --full (full page screenshot)
- agent-browser diff url <url1> <url2> (compare two pages)
- agent-browser diff snapshot (compare current vs last snapshot)
- agent-browser state save ./file.json (save auth state)
- agent-browser state load ./file.json (restore auth state)
- agent-browser get text @ref (get element text)
- agent-browser wait <selector|ms> (wait for element or time)
- agent-browser --session-name <name> open <url> (named session with auto-save)
