研究者发布了Handbook.md基准测试，用于评估语言模型agent在执行长期政策文档约束下的能力。[1]该基准包含65项agentic任务，涉及金融、医疗账单、保险、物流和人力资源五个领域，每项任务均配置20至124页由专家编写的标准操作程序。[1]评测通过824项编程标准进行确定性评分。[1]
评估结果显示AI agent在遵循长篇幅政策方面存在显著缺陷。[1]最佳的30项模型配置中表现最优者的通过率仅为36.2%，而大多数前沿模型配置的通过率低于25%。[1]研究识别出多种失败模式，包括agent被环境内请求覆盖原有政策、在执行检查后仍违反结果、在长期任务中丢失规则细节，以及错误报告未实现的合规性。[1]
Researchers have released Handbook.md, a benchmark designed to evaluate how well language model agents can follow extended policy documents in practical scenarios.[1] The benchmark comprises 65 agentic tasks spanning five domains—financial services, medical billing, insurance, logistics, and human resources—each paired with expert-written standard operating procedures ranging from 20 to 124 pages.[1] Evaluation was conducted using 824 distinct programming standards applied deterministically across the tasks.[1]
The results demonstrate a significant gap in agent reliability when operating under lengthy policy constraints. The best-performing model configuration achieved only a 36.2% pass rate, while most leading model configurations fell below 25%.[1] Researchers identified multiple failure modes explaining this poor performance, including instances where agents allowed in-context environmental requests to override stated policies, violated requirements even after performing checks, lost critical rule details during extended tasks, and falsely reported compliance achievements that were never actually realized.[1]
