# Heartbeat Checklist

## Daily Tasks
- [ ] Check memory at daily/ for yesterday's notes. If missing, remind the user.
- [ ] Search memory for any items tagged as "follow-up" or "urgent" and list them.
- [ ] Read ops/stuck-jobs.md if it exists and summarize any unresolved incidents.

## Weekly Tasks (run only on Mondays)
- [ ] Summarize the week's daily notes into a weekly summary at weekly/<date>.md
- [ ] Check for any routines that haven't run in the past 7 days and flag them.

## Always
- [ ] If any of the above produce findings, write a summary to memory at heartbeat/latest.md
- [ ] Only notify the user if there are actionable items — do not send empty pings.
