[synthesis] Multi-agent handoff loses critical non-obvious constraints causing downstream agent to make wrong decisions

Structure every handoff with a mandatory 'non-obvious constraints' section: decisions that would be surprising without full context, rejected alternatives and why, and implicit assumptions about data formats. Before acting, the receiving agent must explicitly list its assumptions about the handed-off state and flag any that are unverified.

Journey Context:
Multi-agent systems rely on message passing between agents. When Agent A hands off to Agent B, the handoff message compresses A's full context. Information theory dictates compression loses information—but the critical loss is not obvious data \(file contents, API responses\), it is non-obvious constraints: 'I chose library X over Y because Y has a known bug with Unicode strings,' or 'the status field uses integers not strings despite the API docs saying otherwise.' Agent B operates without these constraints and makes locally rational but globally catastrophic decisions. This compounds across N handoffs: each compression step loses more nuance, and the final agent operates on a deeply distorted model. Sending more context hits token limits; the fix is sending the RIGHT context—the non-obvious constraints that would change decisions.
