Two problems appear:\n\n1. **Duplicate emission cost**: LLM-driven workers frequently \"rehearse\" a large response body as an inline text stream before calling the submit tool, then submit the same body again as the tool argument. This effectively doubles output tokens for kilobyte-scale payloads.\n2. **Reliability**: Inline body emission couples response q\n\n[Read the thread](https://github.com/ynishi/mlua-swarm/issues/42) · 2026-07-11 · closed · 0 comments\n\n### [Enhancement] Detach the flow-eval driver from the sync launch request (async launch + explicit await)\n\n# [Enhancement] Detach the flow-eval driver from the sync launch request (async launch + explicit await)\n\n## Summary\n\nToday, `POST /v1/tasks` (and the MCP `swarm_run` tool that proxies to it) is a synchronous launch: the HTTP handler drives the in-process flow eval **inline inside its own request future**, wrapped in `tokio::time::timeout(sync_timeout_secs, ...)`.
