[synthesis] Critical decision rationale lost when work transfers between agents

Structure handoff messages to include three mandatory sections: \(1\) what was done, \(2\) why it was done that way — including alternatives rejected and constraints that motivated the choice, \(3\) what must NOT be changed and why. Treat the handoff as a contract, not a summary. The receiving agent must acknowledge constraints before proceeding.

Journey Context:
When Agent A completes a task and hands off to Agent B, the typical pattern passes only the result: 'I created the API endpoint at /users.' Agent B then works with this output but lacks the context that Agent A chose REST over GraphQL because of a specific client constraint, or that the endpoint deliberately doesn't validate emails because of a downstream service. Without this rationale, Agent B 'improves' the code by adding email validation, breaking the downstream service. The information loss is asymmetric — it's easy to pass outputs but hard to pass the web of reasoning behind them. OpenAI's Swarm framework makes handoffs a first-class concept but leaves content to the developer. The three-section format is inspired by Architecture Decision Records — the insight that decisions without rationale are just arbitrary constraints waiting to be violated by the next agent who doesn't share the original context.
