"""
Desktop Computer-Use Environment Client.

Connects to a running desktop-openenv server and exposes
desktop interaction tools via the MCP tool-calling interface.

Example:
    >>> with DesktopEnv(base_url="http://localhost:8000") as env:
    ...     obs = env.reset(app="libreoffice-calc")
    ...     print("Stream:", obs["metadata"]["stream_url"])
    ...
    ...     # Discover tools
    ...     tools = env.list_tools()
    ...     print([t.name for t in tools])
    ...     # ['screenshot', 'click', 'double_click', 'right_click',
    ...     #  'type_text', 'press_key', 'scroll', 'drag',
    ...     #  'run_command', 'get_cursor_position', 'get_screen_size']
    ...
    ...     # Take screenshot
    ...     img_b64 = env.call_tool("screenshot")
    ...
    ...     # Click on something
    ...     env.call_tool("click", x=500, y=300)
    ...
    ...     # Type text
    ...     env.call_tool("type_text", text="Hello world")
    ...
    ...     # Press key combo
    ...     env.call_tool("press_key", key="ctrl+s")
