OpenAI video frames orchestration layers

- A recent YouTube analysis of OpenAI's open-sourced agent orchestrator framed orchestration as three layered problems: execution, control, and observation. - The video enumerates the layers as tool calls/retries (execution), policy/permissions/fallbacks (control), and traces/intervention signals (observation) for attaching guardrails. - It recommends evaluating orchestrators by their trace exposure, typed tool outcomes, and policy insertion points for incident handling.
