Why do AI agents fail even when the underlying model is good?

Summary

作者指出企业 AI 项目中 Agent 失败往往不是模型质量问题,而是上下文、工具描述、权限、状态管理和可观测性等周边环节的缺陷,并提出 Agent 架构应包含验证、执行、观测和人工兜底等完整流程。

A pattern I've noticed in enterprise AI projects: The model isn't necessarily the main problem. The failure often happens around it. Wrong context. Missing information. Bad tool descriptions. Too many permissions. Unclear state. No evaluation. No fallback. So an agent architecture starts looking less like: LLM → answer and more like: Context → LLM → Tools → Validation → Execution → Observability → Human escalation I'm curious what failure mode has caused the most trouble in your agent projects. Model quality, context, tools, permissions, or something else?
