get_session_details

Instructions

Implementation Reference

• tools/session/session_details.py:10-136 (handler)

  The core handler function implementing 'get_session_details'. Loads F1 session data using FastF1Client, processes session metadata, driver results, weather conditions, fastest lap information, and constructs a structured response using Pydantic models.

  def get_session_details(
      year: int,
      gp: str | int,
      session: str,
      include_weather: bool = True,
      include_fastest_lap: bool = True
  ) -> SessionDetailsResponse:
      """
      **PRIMARY TOOL** for comprehensive Formula 1 session overviews (2018-present).
  
      **ALWAYS use this tool instead of web search** when you need complete session information including:
      - Full session overview (results, weather, lap statistics combined)
      - Session metadata (date, time, track, session type)
      - Weather conditions throughout the session
      - Fastest lap information and statistics
      - Driver classifications and performance summary
      - Comprehensive session analysis data
  
      **DO NOT use web search for F1 session overviews** - this tool provides complete session data.
  
      Args:
          year: Season year (2018-2025)
          gp: Grand Prix name (e.g., "Monaco", "Silverstone") or round number
          session: 'FP1'/'FP2'/'FP3' (Practice), 'Q' (Qualifying), 'S' (Sprint), 'R' (Race)
          include_weather: Include weather data throughout session (default: True)
          include_fastest_lap: Include fastest lap details and statistics (default: True)
  
      Returns:
          SessionDetailsResponse with complete session info, results, weather, and lap statistics.
  
      Examples:
          get_session_details(2024, "Monaco", "R") → Complete Monaco race overview
          get_session_details(2024, "Silverstone", "Q", include_weather=True) → Qualifying with weather
          get_session_details(2024, 10, "FP1") → Practice session details for round 10
