Takeaway

Durable state, isolated environments, and centralized review become essential as agent fleets spread across machines.

Summary

  • A three-machine fleet uses hierarchical agents with scoped contexts and approval boundaries to reduce the operator’s coordination burden.
  • Missions, status, and handoffs persist in files so sessions can reset or restart after crashes without relying on context compaction.
  • Failures included uncontrolled worker growth, memory exhaustion, credential collisions, laptop outages, and conflicting shared context.
  • Git and SSH move work between machines, one always-on review gateway centralizes approvals, and Kubernetes is the planned foundation for scheduling and resource isolation.

Original description
An honest field report from my own personal fleet of AI agents, run across several machines as a daily driver. Less about any single tool, more about the journey: how things that work on one machine break once you scale to many, what it takes to keep a setup like this running, and where it's all converging. Not a company platform — just real, evolving lessons from running it myself.
