Self-Executing AI Agents: Architecture for 24/7 Autonomous Operations

Most AI systems are reactive, waiting for user commands, but production operations require proactive agents that work autonomously 24/7. This three-layer architecture—combining Heartbeat for periodic health checks, Cron for scheduled execution, and a persistent Memory system—enables AI agents to maintain context across sessions and execute work without human intervention. The approach demonstrates how to build and operate 20+ autonomous agents in production while controlling costs and preventing token waste.
