## Summary

LangChain says nearly all emerging proactive agents run as cron tasks that trigger agent runs on a schedule. The post names four cron-driven behaviors: memory consolidation, proactive messages, smart triage, and follow-up reminders. It says more than 70% of Managed Deep Agent runs on LangSmith come from scheduled runs rather than a human typing a message.
