Unverified显式流程描述承担护栏（Guardrail）作用，使 Agent 在遭遇异常时能定位问题并执行回退或重试72% similarVerifiedThe Guardrail mechanism is a system for validating and filtering model inputs and outputs, capable of intercepting sensitive information, illegal requests, or non-compliant content before input enters the model or before output is returned to the user.71% similarUnverifiedThe Guardrail intercepts prompt injection attacks on the input side, reviews generated content on the output side, and sets a cost cap for each session on the budget side, terminating when the cap is reached.69% similarUnverifiedThe interception action of a guardrail is controlled by the Tripwire, a boolean signal: when non-compliant, the tripwire is set to True to interrupt the process; when compliant, it remains False and execution continues.67% similarVerifiedIn AI engineering, guardrails refer broadly to technical mechanisms that constrain the range of model outputs or behaviors, which can be prompt-level instructions or code-level interception logic.64% similar
