- See the discussion topics at a glance.
- Reduce last-minute searching through Slack threads.
- Share one compact agenda with attendees.

- 5Test with one real agenda message.
Questions about this workflow
Does the automation create a calendar event?
No. It creates an image from the Slack agenda message.
How can I keep the card concise?
Ask Notis in the instruction to include only the meeting title, time if present, and key agenda points.
