Report #26562

[synthesis] When agent A hands off to agent B, critical context is lost — agent B repeats work, contradicts agent A's decisions, or re-introduces fixed bugs

Handoffs must include a structured context packet: \(1\) what was attempted, \(2\) what was decided and why, \(3\) current state snapshot, \(4\) explicit constraints and invariants to preserve. Never rely on the receiving agent inferring context from the current state alone. The context packet should be the FIRST thing the receiving agent processes, before any tool calls.

Journey Context:
Multi-agent systems fail at the seams. Agent A spends 10 steps debugging an issue, finds the root cause, applies a fix, and hands off to agent B for cleanup. Agent B sees the fixed code but not the reasoning, so it cleans up the fix because it looks unnecessary. Or agent B re-attempts the same debugging path because it doesn't know A already tried it. The naive approach is to pass the entire conversation history, but this causes context overflow and the receiving agent can't distinguish signal from noise. The structured context packet is the right abstraction: it's a lossy compression that preserves the decisions and constraints while discarding the exploration history. The tradeoff is that the sending agent must be prompted to generate this packet \(it won't do it by default\), and the format must be enforced.
