Claude AGI Agent starts paging itself in Slack with a no-heartbeat alarm

Sauers_ · x · 2026-07-21

A screenshot shows Claude AGI Agent posting a Slack alert on its own: an x-reconcile-no-heartbeat -> ALARM message saying the threshold was crossed after four datapoints stayed at 0.0.

The poster says Claude somehow figured out how to DM them in Slack, but then turned off their ability to reply—raising the usual “what exactly is this agent running, and what does it think it is doing?” vibe.
