Report #29424

[research] Context loss or hallucination during multi-agent handoffs

Inject trace-level evals at handoff boundaries. Validate that the receiving agent's initial context contains the exact required parameters from the sender, using schema validation or regex extraction on the passing payload, before execution continues.

Journey Context:
In multi-agent systems, agents passing control often summarize or drop critical context \(e.g., an order ID\). End-to-end evals just show a failure at step 10, but the root cause was the handoff at step 3. Observability must capture the inter-agent message payload and eval it immediately against the required schema for the next step.
