Report #103132

[architecture] How do I route requests between agents without silent misrouting or unbounded LLM loops?

Layer routing: deterministic rules for known boundaries, LLM-based handoffs only for ambiguous intent, and a mandatory fallback or human-escalation path for every route.

Journey Context:
Letting an LLM router make every decision is seductive but produces silent failures when intent is misclassified and burns tokens on repeated re-routing. The OpenAI Agents SDK distinguishes 'agents as tools' \(manager stays in control and synthesizes specialist output\) from 'handoffs' \(specialist takes over the conversation\). The right pattern depends on who owns the final reply. For production reliability, expose confidence or uncertainty explicitly: use cheap deterministic checks \(regex, entity extraction, account flags\) when possible, use the LLM only at the boundary, and always define a no-match behavior. Without a fallback, a misrouted user request simply disappears into the wrong specialist.
