Could you build this?
Partial Creating a unified router and wrapper API for agent models is vibe-codeable, but provisioning scalable serverless execution sandboxes with bidirectional streaming is complex systems work.
What it would actually take: A complete implementation requires an API gateway that translates disparate agent CLI protocols into a unified schema, backed by an orchestration layer managing ephemeral microVM sandboxes (using technologies like Firecracker, Docker, or E2B). The challenging components are managing secure, multi-tenant sandbox lifecycles with rapid spin-up times, live bidirectional terminal/PTY streaming, stateful file system synchronization, and fine-grained process resource isolation. This demands cloud infrastructure and systems engineers experienced with containerization, WebSockets, and low-latency networking.

Same idea, different domain
Nobody's really built a agent / copilot tool for Agriculture yet.
