Partial Creating a standard API or orchestrator is straightforward, but building an enterprise agent harness with multi-tenant serverless sandboxes, isolated container execution, and streaming sessions requires serious backend infrastructure.
What it would actually take: The stack requires a distributed control plane (Go/Rust or Node), gRPC/HTTP API gateways, and microVM isolation technologies (such as Firecracker, gVisor, or Docker sandboxes) to securely execute arbitrary agent bash commands and code. The hard parts are sub-second sandbox provisioning, secure multi-tenant isolation, real-time bidirectionally streamed stdout/stderr events, and orchestrating stateful session file trees.
