• src/main.py:293-327 (handler)

  The get_last_workout function is defined and decorated as an app.tool, acting as the handler for retrieving the most recent workout matching specified type or tags.

  @app.tool()
  def get_last_workout(
      workout_type: Optional[str] = None,
      tag: Optional[str] = None,
  ) -> dict[str, Any | None]:
      """Get the most recent workout matching type or tag."""

          raise ValueError("At least one of workout_type or tag is required")
  
      conn = get_connection()
      cursor = conn.cursor()
  
      filters: list[str] = []
      params: list[Any] = []
      if workout_type:
          filters.append("workout_type = ?")
          params.append(workout_type)
      if tag:
          filters.append("tags LIKE ?")
          params.append(f'%"{tag}"%')
  
      base = "SELECT * FROM workouts"
      if filters:
          base += " WHERE " + " AND ".join(filters)
      base += " ORDER BY date_time DESC LIMIT 1"
  
      cursor.execute(base, params)
      row = cursor.fetchone()
      if not row:
          conn.close()
          return {"workout": None}
