Security should exist in the execution path (approval binding, state version checks, idempotency keys) rather than in the prompt; a policy that a model can talk its way around does not deserve to be called a guardrail.

UnverifiedGuards sit between the model and the tool functions, bearing responsibility for safety validation by checking before any tool is called, and are a key mechanism for defending against prompt injection and abnormal operations.77% similarVerifiedPolicy guardrails (Guardrails) insert rule validation before executing actions, using deterministic rules as a fallback, such as capping amounts, whitelisting APIs, and requiring explicit confirmation for sensitive operations.75% similarUnverifiedCore rules need to be enforced through side channels (such as hard-coded validators, independent rule-checking layers, and deterministic verification) rather than relying on conversational context.74% similarUnverifiedReview checkpoints should be placed according to risk type rather than process position, and reversible and irreversible operations should be distinguished74% similarVerifiedAn effective prompt injection defense system typically requires a combination of input content filtering, instruction source tracing, and pre-execution intent verification, as relying solely on the model's own safety training is insufficient to resist adversarial examples.74% similar
