[synthesis] Receiving agent in multi-agent handoff trusts previous agent's summary without re-verifying critical facts

At every agent handoff, include pointers to primary sources \(file paths, URLs, raw data\) alongside summaries. Require the receiving agent to spot-check at least one critical fact against a primary source before acting. Never let a summary be the sole basis for a state-mutating decision.

Journey Context:
In multi-agent systems, Agent A produces a summary that Agent B uses as its starting context. If Agent A's summary contains a subtle error—wrong port number, wrong table name, wrong API version—Agent B inherits and amplifies it. Agent B makes additional inferences based on the wrong fact, creating a deeper error. By Agent C, the error is treated as established fact. This is the telephone game problem, and it's worse with LLMs because agents generate fluent, confident summaries that mask uncertainty. The common mistake is making handoffs 'efficient' by passing only conclusions. The fix is to make handoffs auditable: every conclusion must have a traceable source. The tradeoff is that including primary source references increases handoff payload size and adds verification latency, but a single cascading error across 3 agents can cause failures that are exponentially harder to debug because each agent's logic appears internally consistent.
