[synthesis] Critical implicit context lost when one agent hands off to another in multi-agent systems

Structure every handoff with four mandatory fields: \(1\) actions taken and their results, \(2\) rationale for WHY each action was chosen, \(3\) constraints that must be maintained going forward, \(4\) uncertainties and rejected alternatives. Never hand off just the output—hand off the reasoning.

Journey Context:
When Agent A completes its task and hands off to Agent B, the typical pattern passes only the output: 'Here is the refactored module.' But Agent A made dozens of micro-decisions—why it chose one library over another, what edge cases it already handled, what it tried and rejected. Agent B, lacking this context, may undo A's work or make contradictory choices. This is the agent equivalent of a developer joining a project without git history. The compounding effect is severe: each handoff strips another layer of context, and by the third handoff the receiving agent is operating on pure output with zero institutional memory. The four-field handoff structure captures the minimum viable context. The 'rejected alternatives' field is especially important—without it, Agent B will re-explore the same dead ends Agent A already ruled out.
