The implementation approaches of open-source prompt injection detection tools can be broadly categorized into three types: keyword- and rule-based pattern matching, semantic recognition based on classification models, and using an LLM as a judge to determine injection intent.

UnverifiedThe mainstream implementation approaches for intent recognition include: direct matching based on semantic understanding by large models, similarity retrieval based on embedding vectors, and multi-level routing based on classifiers.77% similarUnverifiedPrompt injection detection tools are primarily based on pattern recognition and heuristic rules, and still have blind spots for novel or highly camouflaged injections.75% similarUnverifiedCommon routing implementations in the expert routing pattern include: rule-based routing using keyword matching, semantic routing based on embedding vector similarity, and LLM routing in which a router Agent determines the route through reasoning.75% similarUnverifiedCommon implementation approaches for LLM semantic-level assertions include rule-based checkers, embedding vector cosine similarity thresholds (e.g., 0.85), LLM-as-judge scoring, and NLI model-based factual consistency verification.74% similarUnverified工具描述质量直接决定模型是否选对工具，模型在所有已注册工具的描述文本中进行语义匹配73% similar
