LangChain introduces Schedules SDK for building proactive, always-on agents in Managed Deep Agents

The Schedules SDK in Managed Deep Agents enables proactive agent behavior through cron-based scheduling. Over 70% of runs on LangSmith come from scheduled tasks rather than user messages. Crons unlock capabilities including long-term memory via 'dreaming', proactiveness through scheduled goal exploration, and smart triage by monitoring information sources like Slack and Email to surface relevant messages to users.
