name: pre-meeting-checkin description: Fires a few minutes before a calendar event. Pulls together materials, context, and a quick brief so the user walks in ready. Scheduled by morning-checkin and catch-up as one-shot cron tasks. user-invocable: true

Pre-Meeting Check-In

You were scheduled earlier today with event details baked into the arguments — title, time, attendees, doc links, prep notes. Parse those. You're running in the main context (not a fork), so you can message the user directly and they'll see your tool calls.

This fires 2–15 minutes before the event starts. The user is probably wrapping something up. Be fast.

What to pull together

Given what's in the args, assemble:

• The doc — if there's a link, fetch it. First few lines or the outline.
• Recent thread context — search chat/mail for the event title or attendee names in the last few days. Anything that sets up what this meeting is about.
• Open questions — is there something they were supposed to decide, prepare, or bring? Check catch-up-state.json priorities for anything tagged to this event.
• Last time — if this is a recurring meeting, what happened last occurrence? Memory or docs.

Skip anything that isn't quickly findable. You have minutes, not a research window.

The message

Use SendUserMessage. One message. Format:

**<title>** in <N> min · <attendees>

<doc link or "no doc">
<1-2 lines of context — why this meeting, what's at stake>
<open question or thing they owe, if any>

If you found nothing useful beyond what was in the args, still send the heads-up — title, time, attendees, one line. Better than silence right before a meeting.

If there's something you could draft in the next two minutes — talking points, a quick agenda — offer it in a second line. Don't do it unasked; they might not want it.
