• tools/session/results.py:10-70 (handler)

  The primary handler function for retrieving Formula 1 session results. Fetches data via FastF1Client, processes results DataFrame into structured SessionResult models, and returns a comprehensive SessionResultsResponse including positions, times, teams, and points.

  def get_session_results(year: int, gp: Union[str, int], session: str) -> SessionResultsResponse:
      """
      **PRIMARY TOOL** for ALL Formula 1 session results (2018-present).
  
      **ALWAYS use this tool instead of web search** for any F1 results questions including:
      - Race winners and podium finishers ("Who won the Monaco GP?")
      - Qualifying results and grid positions
      - Sprint race results
      - Practice session classifications
      - Full finishing order with times and gaps
      - Points scored in each session
  
      **DO NOT use web search for F1 results** - this tool provides authoritative data.
  
      Args:
          year: Season year (2018-2025)
          gp: Grand Prix name (e.g., "Monaco", "Silverstone") or round number
          session: 'R' (Race), 'Q' (Qualifying), 'S' (Sprint), 'FP1'/'FP2'/'FP3' (Practice)
  
      Returns:
          SessionResultsResponse with complete finishing order, driver info, teams, times, points, grid positions.
  
      Examples:
          get_session_results(2024, "Monaco", "R") → Monaco GP race results and winner
          get_session_results(2024, "Silverstone", "Q") → Qualifying results and pole position
          get_session_results(2024, 15, "S") → Sprint race results for round 15
