Implementation Reference

• tools/live/pit_stops.py:9-95 (handler)

  The main tool handler function that fetches pit stop data using OpenF1Client, converts to Pydantic models, calculates statistics like fastest/slowest/average pit stop durations, and returns PitStopsResponse.

  def get_live_pit_stops(
      year: int,
      country: str,
      session_name: str = "Race",
      driver_number: Optional[int] = None
  ) -> PitStopsResponse:
      """
      Get pit stop analysis with crew timing from OpenF1.
  
      Args:
          year: Season year (2023+, OpenF1 data availability)
          country: Country name (e.g., "Monaco", "Italy", "United States")
          session_name: Session name - 'Race', 'Qualifying', 'Sprint', 'Practice 1/2/3' (default: 'Race')
          driver_number: Optional filter by driver number (1-99)
  
      Returns:
          PitStopsResponse with pit stop durations and statistics
  
      Example:
          get_live_pit_stops(2024, "Monaco", "Race") → All pit stops with timing
          get_live_pit_stops(2024, "Monaco", "Race", 1) → Verstappen's pit stops
