What causes autonomous AI agents to stop running?

Timezone mismatches, session mode errors, and skipped verifications — like this 7-hour cron fail — turn heartbeats into snoozes.

How do you make AI agents reliable?

Enforce UTC timestamps, main-session alarms, and post-set checks via cron list. Add external monitors for production.

Will AI agents replace cron jobs entirely?

Doubt it — cron’s too entrenched. But expect agent-specific schedulers with built-in failovers by next year.
