      calendar: primary
      time_min: today_start
      time_max: today_end
      
  2. categorize_events:
      categories:
        meetings: has_attendees == true
        focus_time: title contains "Focus" OR "Deep Work"
        one_on_ones: title contains "1:1" OR "1-on-1"
        interviews: title contains "Interview"
        
  3. calculate_stats:
      total_meetings: count(meetings)
      total_hours: sum(duration)
      free_time: 8 - total_hours
      back_to_back: count(gap < 15min)
      
  4. format_message:
      template: |
        ☀️ *Good morning! Here's your day:*
        
        📅 *{date}*
        
        *Schedule Overview:*
        • {total_meetings} meetings ({total_hours}h)
        • {free_time}h of free time
        • {back_to_back} back-to-back slots ⚠️
        
        *Today's Events:*
        {event_list}
        
        💡 *Tip:* {daily_tip}
        
  5. send_to_slack:
