A workflow guardrail is an explicit rule that limits what an AI agent may decide or do, defines required evidence, and determines when work must pause or escalate to a person.
Examples of freight guardrails
Examples include rate floors, maximum negotiation ranges, approved lanes and equipment, carrier authority requirements, message templates, customer-specific service rules, confidence thresholds, and mandatory approval for exceptions.
