[research] Agent handoffs between sub-agents or tools result in context loss or hallucinated state

Instrument trace-level spans specifically for LLM context injection. Verify that the exact context passed to the receiving agent matches the output context of the sender using trace IDs.

Journey Context:
In multi-agent systems, handoffs are the weakest link. Agents often summarize or hallucinate state during handoffs rather than passing exact JSON. Without span-level tracing on the context payload, these hallucinations are invisible until the final output is wrong.
