UnverifiedThe whitelist approach, which only declares permitted component types and properties, is safer than a blacklist because the model's output space is nearly infinite and attackers can always find variants not on the blacklist.68% similarUnverifiedThe fail-closed intuition of a whitelist only holds in single-layer decision-making; once the decision chain is split into a selector layer and a verdict layer, the whitelist only provides fail-closed guarantees at the verdict layer.66% similarUnverifiedA default-deny tool allowlist is the single highest-impact change among the five layers of defense: tool calls not on the allowlist are rejected outright, and side-effect tools require approval.64% similarUnverifiedThe choice type always selects one option, and if no abstention option is provided, the model is forced to give an answer even when evidence is insufficient; the Learn documentation recommends adding an abstention option when a choice should not be forced.64% similar
