Tool Execution Pattern

​
Dynamic Tool Creation

Tools are created dynamically based on:
  • User’s active integrations
  • Available credentials
  • User permissions
  • Context requirements
Example: 
# User with Google Calendar connected
tools = [
    search_web,
    read_webpage,
    create_calendar_event,  # ✓ Available
    search_calendar,        # ✓ Available
    send_message
]

# User without Google Calendar
tools = [
    search_web,
    read_webpage,
    # Calendar tools not available
    send_message
]

​
Tool Descriptions

Each tool has clear descriptions for the AI: 
@tool
async def create_calendar_event(
    title: str,
    start_time: datetime,
    end_time: datetime,
    attendees: Optional[List[str]] = None
):
    """
    Creates a calendar event.

    Args:
        title: Event title
        start_time: Event start (ISO format)
        end_time: Event end (ISO format)
        attendees: Email addresses of attendees

    Returns:
        Event details and confirmation
    """
