[frontier] Multi-agent handoffs lose context or inject noise — passing raw conversation history between agents causes confusion

Define a structured handoff schema \(current\_task\_state, completed\_steps, remaining\_steps, blockers, key\_decisions, artifacts\_produced\) and require agents to populate it when transferring control. Pass only the schema object plus minimal relevant context to the receiving agent.

Journey Context:
The naive approach to agent handoffs is passing the entire conversation history to the next agent. This causes context pollution: the receiving agent gets confused by irrelevant details, intermediate reasoning, and tool outputs from earlier steps that it doesn't need. OpenAI's Swarm framework introduced the handoff primitive but left the payload format open. The emerging best practice is a structured handoff object that acts like a baton in a relay race: compact, standardized, and containing only what the next agent needs. The key insight is that the handoff schema is domain-specific: a code-review handoff needs different fields than a deployment handoff. The tradeoff: designing good handoff schemas takes iteration, and over-compressing can lose critical context \(e.g., why a previous approach was rejected\). But in practice, structured handoffs dramatically reduce the 'confused agent' problem where the receiving model fixates on irrelevant prior conversation and makes poor decisions.
