What it does

Instead of a weekly batch report, this guardrail reacts in real time. Each time a calendar event is created or accepted, it recomputes that day's total meeting hours and remaining free windows. If the new event tips the day over a configurable meeting-hours cap or eliminates the day's last 90-minute focus block, it fires an instant Slack direct message so you can decline or reschedule while there's still room.

When to use it

Use it when over-booking happens through a thousand small yeses and you want a tripwire at the moment of damage, not a post-mortem on Friday. Best for people who accept invites quickly and regret it later.

How it works

  1. 1An event trigger fires on new or changed Google Calendar events.
  2. 2The flow recomputes the affected day's meeting hours and free blocks.
  3. 3A logic step checks the day against the hours cap and focus-block rule.
  4. 4If a threshold is crossed, it composes a contextual warning naming the offending event.
  5. 5The alert is delivered as a Slack direct message to the calendar owner.
