Report #23967

[research] Multi-agent system produces wrong outputs because context is lost or garbled at handoff boundaries

At each agent handoff, log the full transferred context payload in the trace span. Add a handoff verification step where the receiving agent confirms it has the required information before proceeding. Tag each span with agent identity and handoff sequence number. Alert on handoffs where the receiving agent's first action is requesting information that should have been in the transfer.

Journey Context:
Multi-agent handoffs are the primary source of silent failures in agentic systems. The sending agent summarizes or compresses context, losing critical details. The receiving agent does not know what it does not know. This compounds in long chains \(A -> B -> C -> D\) where each handoff loses information. The fix has two parts: observability \(you must see exactly what context was transferred\) and verification \(the receiver confirms receipt of required info\). The tradeoff is added latency and token cost for verification, but this catches handoff failures early before they cascade into wrong final outputs that are expensive to debug.
