## Summary

Google engineers Brandon Royal and Benjamin Elder explain how Agent Substrate, an open-source project built on Kubernetes, isolates AI agents in hardened sandboxes. The system injects credentials outside the sandbox and snapshots idle agents out of memory and CPU to free cluster resources, according to Elder. Google's Gemini Managed Agents already runs on Agent Substrate.
