In this post (Part 2), you will learn how each layer works and what it looks like in working code.
发生了什么
AWS 作者展示了开源数据分析解决方案 Deep Insight 如何借助 Strands Agents SDK 和 Amazon Bedrock AgentCore 应用四层上下文工程。演示涵盖 Agent 之间的上下文隔离、提示词规则、基于文件系统的工具和笔记，以及独立验证保护机制。在参考实现中，合并写入与执行功能的工具可将每个脚本增加的令牌数减少约 95%，而按需加载技能可将系统提示词缩短约 97%。
推荐理由
Deep Insight 演示展示了四层上下文工程如何协同工作，并介绍了实现细节，以及脚本输出和按需加载技能所报告的令牌数减少情况。

查看这件事的完整进展AWS Shows Four Context Engineering Practices for Production AI Agents这件事到目前为止
AWS Machine Learning Blog authors demonstrated four layers of context engineering in Deep Insight, an open-source data analysis solution built with the Strands Agents SDK and Amazon Bedrock AgentCore. The practices cover isolating context across agents, setting prompt rules, using filesystem-based tools and notes, and adding independent verification safeguards. In the reference implementation, a combined write-and-execute tool reduces the tokens added by each script by about 95 percent. Loading skills on demand reduces the system prompt by about 97 percent.
