AI Agents represent a paradigm shift from passive text generation to active task execution, combining LLMs with planning, tool use, and memory to automate complex workflows. This article explores their architecture, working principles, and practical applications in content creation, highlighting the transition from chatbots to intelligent executors. AI智能体标志着从被动文本生成到主动任务执行的范式转变，它结合了大语言模型、规划、工具使用和记忆功能，能够自动化复杂工作流程。本文探讨了其在内容创作领域的架构、工作原理和实际应用，强调了从聊天机器人到智能执行者的转变。

LLMs.txt and llms-full.txt are specialized document formats designed to provide Large Language Models (LLMs) and AI agents with structured access to programming documentation and APIs, particularly useful in Integrated Development Environments (IDEs). The llms.txt format serves as an index file containing links with brief descriptions, while llms-full.txt contains all detailed content in a single file. Key considerations include file size limitations for LLM context windows and integration methods through MCP servers like mcpdoc. (llms.txt和llms-full.txt是专为大型语言模型和AI智能体设计的文档格式，提供对编程文档和API的结构化访问，在集成开发环境中尤其有用。llms.txt作为索引文件包含带简要描述的链接，而llms-full.txt将所有详细内容整合在单个文件中。关键考虑因素包括LLM上下文窗口的文件大小限制以及通过MCP服务器的集成方法。)

Browser-Use is an open-source AI-powered browser automation platform that enables AI agents to interact with web pages like humans—navigating, clicking, filling forms, and scraping data—through natural language instructions or program logic. It bridges AI models with browsers, supports multiple LLMs, and offers both no-code interfaces and SDKs for technical and non-technical users. (Browser-Use是一个开源的AI驱动浏览器自动化平台，让AI代理能像人类一样与网页交互：导航、点击、填表、抓取数据等。它通过自然语言指令或程序逻辑连接AI与浏览器，支持多款LLM，并提供无代码界面和SDK，适合技术人员和非工程背景人员使用。)

English Summary: This comprehensive guide from Anthropic shares practical insights on building effective LLM agents, emphasizing simplicity over complexity. It distinguishes between workflows (predefined code paths) and agents (dynamic, self-directed systems), provides concrete patterns like prompt chaining, routing, and parallelization, and offers guidance on when to use frameworks versus direct API calls. The article stresses starting with simple solutions and adding complexity only when necessary, with real-world examples from customer implementations. 中文摘要翻译：本文是Anthropic分享的关于构建高效LLM智能体的实用指南，强调简单性优于复杂性。文章区分了工作流（预定义代码路径）和智能体（动态、自导向系统），提供了提示链、路由、并行化等具体模式，并就何时使用框架与直接API调用提供了指导。文章强调从简单解决方案开始，仅在必要时增加复杂性，并提供了客户实施的真实案例。
