Questions about Multi-agent collab: sub-agent interruptions + orchestrator prompting + evals

Problem

In Codex multi-agent/collab, the orchestrator frequently interrupts sub-agents and the sub-agents end up getting little done. Net effect: added coordination overhead, worse wall-clock completion.

Questions

1. Are there plans to improve the orchestrator prompts/default behavior so sub-agents aren’t repeatedly derailed mid-task?
2. What are the intended semantics for the messages—are sub-agents being hard-stopped vs steered?
3. Any current or planned evals comparing multi-agent vs single-agent on success rate, quality, wall-clock time, and overhead?
