An open connection keeps the sandbox active and billed\n2. Set a TTL or idle expiry on throwaway sandboxes. The default is to keep them\n3. Set `forbiddenDomains` or an allow list at creation, with `network.firewall` for tools that ignore proxy settings. Both can only be set when the sandbox is created\n4. Retry only on WORKLOAD_UNAVAILABLE. The error reference says other codes won't succeed on retry\n5. Connect to `\u003csandbox URL\u003e/mcp` with your API key instead of wrapping the REST API in tools yourself\n\n### Runloop Devboxes\n\n1. Set an idle policy (`idle_time_seconds` with `on_idle: suspend`) so a forgotten devbox stops billing compute\n2. Route outbound API calls through an agent gateway instead of putting keys in the devbox environment\n3. Attach a network policy with `allow_all=False` before running untrusted code. Egress is open by default\n4. Restart background services after every resume. Nothing in memory survives\n5.
