You built an AI agent to follow up with clients, and now it quietly runs in the background. But what happens the day the machine reboots, the internet drops, and your agent just stops, and you have no idea? In this episode, Shaun walks through the same problem he hit building an executive assistant agent on a local Mac Mini. The fix is a heartbeat: a small outside service that pings your system on a set cadence and pokes you when it goes quiet. He shares the free tool he landed on, healthchecks.io, how he set a 10-minute check with a 15-minute grace window, and why the monitor has to live outside the machine it's watching. Think of it like a wellness check for the family member who lives alone.
