Agent

askui.VisionAgent

class VisionAgent()

A vision-based agent that can interact with user interfaces through computer vision and AI.

This agent can perform various UI interactions like clicking, typing, scrolling, and more. It uses computer vision models to locate UI elements and execute actions on them.

Arguments:

log_level int | str, optional - The logging level to use. Defaults to logging.INFO.
display int, optional - The display number to use for screen interactions. Defaults to 1.
model_router ModelRouter | None, optional - Custom model router instance. If None, a default one will be created.
reporters list[Reporter] | None, optional - List of reporter instances for logging and reporting. If None, an empty list is used.
tools AgentToolbox | None, optional - Custom toolbox instance. If None, a default one will be created with AskUiControllerClient.
model ModelComposition | str | None, optional - The default composition or name of the model(s) to be used for vision tasks. Can be overridden by the model parameter in the click(), get(), act() etc. methods.

Example:

from askui import VisionAgent

with VisionAgent() as agent:
    agent.click("Submit button")
    agent.type("Hello World")
    agent.act("Open settings menu")

act

def act(
    goal: Annotated[str, Field(min_length=1)],
    model: str | None = None
) -> None

Instructs the agent to achieve a specified goal through autonomous actions.

The agent will analyze the screen, determine necessary steps, and perform actions to accomplish the goal. This may include clicking, typing, scrolling, and other interface interactions.

Arguments:

goal str - A description of what the agent should achieve.
model str | None, optional - The composition or name of the model(s) to be used for achieving the goal.

Example:

from askui import VisionAgent

with VisionAgent() as agent:
    agent.act("Open the settings menu")
    agent.act("Search for 'printer' in the search box")
    agent.act("Log in with username 'admin' and password '1234'")

cli

def cli(command: Annotated[str, Field(min_length=1)]) -> None

Executes a command on the command line interface.

This method allows running shell commands directly from the agent. The command is split on spaces and executed as a subprocess.

Arguments:

command str - The command to execute on the command line.

Example:

from askui import VisionAgent

with VisionAgent() as agent:
    agent.cli("echo Hello World")  # Prints "Hello World"
    agent.cli("ls -la")  # Lists files in current directory with details
    agent.cli("python --version")  # Displays Python version

click

def click(
    locator: Optional[str | Locator] = None,
    button: Literal['left', 'middle', 'right'] = 'left',
    repeat: Annotated[int, Field(gt=0)] = 1,
    model: ModelComposition | str | None = None
) -> None

Simulates a mouse click on the user interface element identified by the provided locator.

Arguments:

locator str | Locator | None, optional - The identifier or description of the element to click. If None, clicks at current position.
button ‘left’ | ‘middle’ | ‘right’, optional - Specifies which mouse button to click. Defaults to 'left'.
repeat int, optional - The number of times to click. Must be greater than 0. Defaults to 1.
model ModelComposition | str | None, optional - The composition or name of the model(s) to be used for locating the element to click on using the locator.

Example:

from askui import VisionAgent

with VisionAgent() as agent:
    agent.click()              # Left click on current position
    agent.click("Edit")        # Left click on text "Edit"
    agent.click("Edit", button="right")  # Right click on text "Edit"
    agent.click(repeat=2)      # Double left click on current position
    agent.click("Edit", button="middle", repeat=4)   # 4x middle click on text "Edit"

    image: Optional[Img] = None,
    response_schema: Type[ResponseSchema] | None = None,
    model: str | None = None
) -> ResponseSchema | str

Retrieves information from an image (defaults to a screenshot of the current screen) based on the provided query.

Arguments:

query str - The query describing what information to retrieve.
image Img | None, optional - The image to extract information from. Defaults to a screenshot of the current screen. Can be a path to an image file, a PIL Image object or a data URL.

model str | None, optional - The composition or name of the model(s) to be used for retrieving information from the screen or image using the query. Note: response_schema is not supported by all models.

Returns:

ResponseSchema | str: The extracted information, str if no response_schema is provided.

Limitations:

Nested Pydantic schemas are not currently supported
Schema support is only available with “askui” model (default model if ASKUI_WORKSPACE_ID and ASKUI_TOKEN are set) at the moment

class UrlResponse(JsonSchemaBase):
    url: str

with VisionAgent() as agent:
    # Get URL as string
    url = agent.get("What is the current url shown in the url bar?")

    # Get URL as Pydantic model from image at (relative) path
    response = agent.get(
        "What is the current url shown in the url bar?",
        response_schema=UrlResponse,
        image="screenshot.png",
    )
    print(response.url)

Arguments:

x int - The horizontal scroll amount. Positive values typically scroll right, negative values scroll left.
y int - The vertical scroll amount. Positive values typically scroll down, negative values scroll up.

Notes:

The actual scroll direction depends on the operating system’s configuration. Some systems may have “natural scrolling” enabled, which reverses the traditional direction.

The meaning of scroll units varies across operating systems and applications. A scroll value of 10 might result in different distances depending on the application and system settings.

Example:

from askui import VisionAgent

with VisionAgent() as agent:
    agent.mouse_scroll(0, 10)  # Usually scrolls down 10 units
