# 闭世界解析方法解决LLM Agent调用不存在工具的问题

arXiv论文针对LLM Agent的工具幻觉问题提出闭世界解析方法。Agent会调用不存在的工具或传入没有schema声明的参数，而现有防御手段要么只解决工具选择，要么只解决工具安全，均未覆盖这一失败模式。该论文提出的方法专门应对Agent调用虚构工具和非法参数的情况。具体方案和实验结果参见论文全文。

## English Version

**Closed-World Resolution Targets Tool Hallucination in LLM Agents**

A paper on arXiv proposes a closed-world resolution method targeting tool hallucination in LLM agents. Agents call tools that do not exist and pass arguments no schema declares, a failure mode unaddressed by existing tool-selection or tool-security defenses. The proposed method specifically handles agents invoking non-existent tools and invalid arguments. Technical details and results are in the full paper.
