Real-Time Overbooking Guard on New Meeting Invites

When a new calendar invite lands, it recalculates that day's meeting density and, if the day tips into overload, alerts you in Slack with the conflicting focus time…

What it does

This workflow reacts the instant a new event is added to your calendar. It recomputes the affected day's total meeting hours and back-to-back streaks, and if the new invite pushes the day past your overload limit or collides with a protected focus block, it warns you immediately with a recommended action.

When to use it

Use it when meetings get booked onto your calendar by others and you want a live tripwire rather than discovering an over-stacked day the morning of. Ideal for people whose calendars are open to colleagues.

How it works

  1. 1A Google Calendar event-created trigger fires when a new invite appears.
  2. 2The workflow loads the full set of events for that same day.
  3. 3A logic step recalculates total booked hours, back-to-back count, and any overlap with existing focus holds.
  4. 4If the day now exceeds the threshold or eats a focus block, an OpenAI step writes a short rationale and a decline-or-reschedule recommendation.
  5. 5The alert is delivered to your Slack DM so you can act before the meeting cements.
