Could you build this?
Partial Building the routing API facade and dashboard is simple, but providing a resilient, managed runtime that reliably executes, isolates, resumes, and streams long-horizon agent CLI harnesses across varied environments is non-trivial.
What it would actually take: The architecture requires an API gateway (Go/Node.js) backed by distributed container sandboxes (Fly Machines, Docker, or Firecracker) managing stateful execution loops, WebSocket event streams, and virtual file mounts. The difficult component is orchestrating interactive CLI agents (like Codex or Claude Code), managing credential pass-through, robust error recovery/checkpoints, and sandbox lifetime economics. It requires distributed systems and infrastructure reliability engineering expertise.
