Report #61329

[research] Multi-agent handoffs lose critical state or hallucinate constraints because the receiving agent only gets a summarized message

Pass a structured handoff payload containing the exact tool outputs and constraints gathered so far, rather than relying on the transferring agent to summarize. Trace this payload as a distinct span in your observability tool.

Journey Context:
When Agent A hands off to Agent B, if Agent A summarizes 'I couldn't find the file', Agent B lacks the actual file paths tried and may repeat the exact same failing search. Passing the raw trace data \(or a structured subset\) prevents hallucination and redundant tool calls. OpenTelemetry for LLMs uses trace sessions to link these, but the payload itself must be explicitly forwarded.
