[research] Context lost or hallucinated during multi-agent handoffs causing downstream agent failure

Implement trace-level evals specifically at handoff boundaries by injecting a summarization check that verifies the receiving agent's initial context contains the exact required state variables from the sender.

Journey Context:
When Agent A hands off to Agent B, developers often just pass the full chat history. This bloats context and B ignores A's key outputs, or A's summary misses a crucial variable. By adding a targeted eval/assertion right at the handoff trace—checking if B's system prompt plus injected summary contains the necessary IDs/states—you isolate handoff failures from general agent incompetence.
