New benchmark across 1,039 tasks shows structured agent handoffs beat chat summaries
ombre-ai · reddit · 2026-11-09
A new benchmark tests whether a receiving agent can recover repository evidence and continue from a prior agent's conversational, tool and file state — not just whether it remembers a summary. Across 1,039 tasks, structured handoff state improved evidence recovery for every receiving model and continuation for most. The author argues "summarize the conversation" is the wrong handoff primitive, and proposes handoffs should capture decisions, rejected options with reasons, supporting evidence, what's been tried, and the exact next action.
