Five signals agent handoff summaries silently drop, and the fields that could preserve them

ombre-ai · reddit · 2026-11-04

A Reddit author frames agent-to-agent handoffs as compression steps where the summary is written from the sender's perspective, mapping five commonly lost signals to symptoms and proposed schema fields: decision rationales (decisions [{choice, reason}]), unstated constraints, claim confidence tags (verified/inferred/guess), ordered attempt history, and rejected approaches — each preventing a downstream failure like reversed decisions or re-proposed dead ends. He flags open questions: when does schema overhead cost more tokens than it saves, and do agents over-trust their own "verified" labels? Noting Anthropic's multi-agent research write-up already covered structured subagent outputs, he asks which fields practitioners actually kept after real runs.
