[frontier] Agent handoffs losing critical context forcing the receiving agent to re-derive state from scratch
When handing off between agents, pass a structured handoff packet containing: the original goal, approaches tried and their outcomes, current state and progress, constraints discovered, and an explicit next-step suggestion. Never hand off with just the task description.
Journey Context:
The naive handoff is simply passing the task description. The receiving agent starts from scratch, often re-trying approaches that already failed or re-discovering constraints the previous agent already found. This wastes turns and tokens. The structured handoff pattern formalized in the OpenAI Agents SDK passes accumulated intelligence: what was tried, what failed and why, what constraints exist, and what the next step should be. The tradeoff is that the handoff packet consumes context in the receiving agent, but this is far cheaper than re-deriving the same information through exploration. Think of it as the difference between a good and bad shift change: the good one leaves detailed notes on what happened, the bad one leaves you to figure it out alone.
