Show HN: I sandboxed OpenAI's Symphony orchestrator in one file using YSA (opens in new tab)

YSA is an open source sandbox runtime for AI agents. Each task runs in an isolated Podman container with a network proxy that filters every outbound request.

This example repo shows how to connect it to Symphony (OpenAI's agent orchestrator) — the entire integration is one new file, runner/ysa.ts.

The demo shows an agent attempting to POST data to an external URL and getting blocked by the network proxy.
