What it does

Some recurring meetings die quietly — attendance dwindles occurrence by occurrence until two people sit in a room out of habit. This workflow runs monthly, looks back across the last several instances of each series, and surfaces the ghosts: series with a clear downward attendance trend. For each one it posts the organizer a short, evidence-backed message proposing cancellation.

When to use it

Use it as a recurring cleanup pass for teams and orgs. It catches the meetings nobody will volunteer to kill because no single occurrence feels bad enough. The historical trend, not a single low turnout, is what makes the case persuasive.

How it works

  1. 1A monthly schedule fires the run.
  2. 2It pulls past instances of each recurring series from Google Calendar with attendee responses.
  3. 3Logic computes an attendance trend per series and flags sustained declines, not one-off dips.
  4. 4For flagged series, OpenAI writes a concise cancellation case citing the trend numbers.
  5. 5The organizer gets the case as a Slack message; a summary row per ghost series is appended to an Airtable tracker.
