AWS教你用Strands Evals自动揪出AI Agent的失败根因，还告诉你该改提示词还是工具定义，比盲猜管用多了。
AWS博客介绍了Strands Evals工具，用于检测AI Agent执行中的失败并定位根因。调用detector函数后，输出包含分类失败类型与置信度分数、从根因到下游症状的因果链，以及修复建议（指定修改系统提示还是工具定义）。该工具可集成到评估流程中，实现每个测试运行的自动诊断。

AI Agent Failure Detection and Root Cause Analysis with Strands Evals
In this post, we walk you through calling the detector functions to diagnose real agent failures. You learn how to interpret their structured output: categorized failures with confidence scores, causal chains linking root causes to downstream symptoms, and fix recommendations specifying whether a change belongs in your system prompt or tool definitions. You also learn how to integrate detection into your evaluation pipeline for automated diagnosis on every test run.
