Use boolean response schemas to check UI states, verify conditions, and make decisions in your automation flows.

​
Basic Usage

from askui import VisionAgent

with VisionAgent() as agent:
    agent.tools.webbrowser.open_new("http://www.example.com")
    agent.wait(3)  # Wait for page to load

    is_loaded = agent.get("Is the page fully loaded?", response_schema=bool)
    assert is_loaded, "Page should be loaded"

    print(f"is loaded: {is_loaded}")

Best Practices

  1. Be Specific: Ask precise questions about what you’re checking 
    # Good - specific
is_error = agent.get("Is there a red error message below the email field?", response_schema=bool)

# Less specific
is_error = agent.get("Is there an error?", response_schema=bool)
  2. Use for Control Flow: Boolean questions are perfect for conditional logic 
    if agent.get("Is the cookie banner visible?", response_schema=bool):
    agent.click("Accept cookies")

# Continue with main flow
  3. Combine Multiple Checks: Use multiple boolean questions for complex validations 
    can_proceed = all([
    agent.get("Is the form completely filled?", response_schema=bool),
    agent.get("Is the terms checkbox checked?", response_schema=bool),
    not agent.get("Are there any validation errors?", response_schema=bool)
])
