Report #98390

[architecture] Handoffs pass only text summaries, losing tool outputs, citations, and reasoning traces

Carry the full structured trace \(tool calls, results, artifacts\) in the handoff payload and let the receiver filter and summarize, not the sender.

Journey Context:
Compressing context to a paragraph seems token-efficient, but it discards the exact evidence the next agent needs to verify or continue. Structured traces preserve provenance and make failures debuggable. Protocols like A2A model results as typed Artifacts/Parts precisely so receivers can select what matters. The cost is larger payloads; the benefit is correctness and auditability.
