用 LangGraph 和 Amazon Bedrock AgentCore Web Search 搭建每日依赖监控
Build a daily dependency watcher with LangGraph and Amazon Bedrock AgentCore web search
AWS 出的实战教程，教你用 LangGraph 加 Bedrock AgentCore 的 Web Search API 做一个每日依赖监控智能体。亮点是规则写代码里、搜索结果带引用可核验，还能并行查多个包生态。常维护开源依赖的工程师可以直接照抄这套工作流。
AWS 机器学习博客发布教程，介绍用 Amazon Bedrock AgentCore 的 Web Search API 与 LangGraph 构建每日依赖监控工具。该 API 能为智能体提供带引用来源的网络搜索结果，并使用已有的 AWS 凭证签名调用，无需单独配置搜索服务密钥。
教程中的工作流将监控逻辑拆分为一个 LangGraph 图：规则全部写在代码里而非提示词中，多个包生态（如 npm、PyPI 依赖）的研究任务并行执行，每条发现都会对照引用来源逐一核验，降低幻觉和误报。
对需要追踪依赖版本、安全公告和 breaking changes 的工程团队来说，这套模式可以低成本接入现有 AWS 环境，也展示了如何把"搜索—核验—报告"流程固化为可复用的智能体工作流。
Build a daily dependency watcher with LangGraph and Amazon Bedrock AgentCore web search
The Web Search API in Amazon Bedrock AgentCore gives agents current, cited web results signed with the AWS credentials they already use. In this post, build a daily dependency watcher as a LangGraph graph that researches package ecosystems in parallel, keeps its rules in code, and checks every finding against its cited sources.
