[research] Agent handoffs silently route to the wrong specialist or lose context

Treat each handoff as a function tool with structured input\_type metadata and an input\_filter; evaluate routing correctness, the metadata emitted, and whether the specialist received the right history.

Journey Context:
OpenAI Agents SDK implements handoffs as function calls named transfer\_to\_, so routing is a tool-selection problem that can be logged and scored. input\_type lets the model emit reason/priority/summary that you can assert against, while input\_filter controls context leakage and token waste. The trap is only grading final answers: a handoff can reach the right agent but pass polluted history and still fail. Anthropic's multi-agent research system evaluates end-state and process quality because valid paths differ across runs.
