[architecture] Downstream agent receives factually incorrect or misformatted output from upstream agent

Insert a lightweight 'Verifier' agent \(or programmatic assertion\) at the handoff boundary that evaluates the output against the original goal before passing the baton.

Journey Context:
Trusting an agent to 'do it right the first time' fails in complex tasks. A common mistake is making the downstream agent both verify the input and do its job, which splits its attention and degrades performance. Separating verification into a distinct step \(LLM-as-a-judge or deterministic script\) ensures the contract is met. The tradeoff is increased latency and token cost, but it drastically reduces cascading error rates in multi-step pipelines.
