[frontier] Agent handoffs lose critical context or waste tokens on irrelevant conversation history

Generate a structured 'handoff brief' at every agent transfer: current objective, key decisions made, relevant facts discovered, specific ask for the receiving agent, and any constraints. Pass only the brief—not the full conversation history—to the receiving agent.

Journey Context:
The OpenAI Swarm pattern introduced handoffs as a primitive, but naive implementations either forward everything \(the receiving agent gets confused by irrelevant history and wastes tokens\) or too little \(critical context is lost\). The handoff brief pattern—where the departing agent explicitly generates a structured summary for the next agent—is emerging as the production standard. It is analogous to a shift handoff in operations. The tradeoff is one extra LLM call to generate the brief, but receiving agents perform significantly better with focused context. OpenAI's Agents SDK formalizes this with context\_variables, but the brief pattern goes further by making the departing agent responsible for curating what matters.
