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.
