VerifiedThere is currently no perfect defense against prompt injection in the industry; the primary approach relies on multi-layered protection strategies, including input filtering, output detection, and the model's own instruction-following capability.77% similarUnverifiedCurrently there is no mature universal defense against prompt injection in the industry, and instruction-priority isolation at the model level remains an active area of research.69% similarUnverified在提示工程领域，负向约束通过明确「不应该做什么」来引导输出，是一种重要但常被忽视的技巧67% similarUnverified文章提出三种提示词策略引导AI跳出常规思维：排除法、约束驱动法和多轮迭代法67% similarUnverifiedThe core value of an external policy layer lies in its non-bypassability — even if the agent code is tampered with or subjected to a prompt injection attack, it can still serve as the last line of defense.66% similar
