Security, meanwhile, belongs to no single chapter; it is a cross-cutting concern of the whole book (a cross-cutting concern touches many parts of a system at once—the way logging, in software engineering, has to thread through every module). The table below presents the Harness functions, security aspects, and corresponding chapters in a single view:\n\n| Harness Focus | Corresponding Chapter | Core Content | Security Concerns |\n|--------------------|--------------------|-------------------------------|------------------------|\n| Context Design | Chapter 2 (Context Engineering) | Prompt engineering, Agent status bar, context compression, Agent Skills | Prompt injection and information leakage |\n| Context Expansion (Knowledge Persistence) | Chapter 3 (Knowledge Base) | User memory, RAG, structured indexing, agentic RAG | Sensitive information exposure, privacy protection |\n| Tool Design and Security Constraints | Chapter 4 (Tool Design) | Tool classification, permission control, MCP standard, asynchronous architecture | Misoperation, unauthorized access, irreversible operations |\n| Tool Verification and Correction | Chapter 5 (Code Generation) | Coding Agent's Harness, test-driven development, codified rules | Identity impersonation, responsibility attribution |\n| System-Level Verification | Chapter 6 (Evaluation) | Evaluation environment, datasets, automated evaluation, observability | — |\n| Model-Level Correction | Chapter 7 (Post-Training) | SFT (Supervised Fine-Tuning), Reinforcement Learning—encoding feedback signals accumulated by the Harness into model parameters, as an extension of Harness engineering | Goal misalignment, alignment and robustness |\n| System-Level Correction | Chapter 8 (Self-Evolution) | Externalized learning, tool creation, experience accumulation | — |\n| Multimodal Context and Tools | Chapter 9 (Multimodal and Real-Time Interaction) | Voice Agent, Computer Use, robotic operation | Security filtering of multimodal input, permission control in real-time interaction |\n| Constraints and Corrections Among Multiple Agents | Chapter 10 (Multi-Agent Collaboration) | Collaboration architecture, failure modes, Agent society | Trust boundary violations between Agents, shared resource conflicts |\n\nAnthropic's practice in building long-running Agents shows how Harness design can solve problems the model itself cannot. They split complex tasks between an \"Initialization Agent\" (setting up the environment, decomposing the task list) and an \"Execution Agent\" (making incremental progress each session and leaving clear handover artifacts), using a structured Harness to tackle the two failure modes of long tasks: running out of context and declaring the task done prematurely. The chapters ahead work through the Harness component by component—Chapter 2 begins with the most central one, context engineering, and Chapter 5 lays out the complete practice of Harness engineering in Coding Agents.\n\n## Chapter Summary\n\nThis chapter has built a practice-first framework for understanding and constructing AI Agents.\n\n**Agent = Reasoning Engine + Working Context + Action Interfaces**: The LLM provides reasoning and decision-making, context supplies the working set of information available at decision time, and tools provide the action interfaces. None of the three is dispensable.\n\n**Expanding Context and Tools Is the Primary Capability Lever**: Once the model is fixed, redefining or enlarging the observation and action spaces—that is, expanding context and tools—can often turn an unsolvable task into a solvable one directly. The evolution from Manus to OpenClaw shows that much of generality comes from broadening the interface boundary; that expansion must remain on-demand and be paired with permissions and verification.\n\n**Context Is the Decisive Factor**: Context consists of a static prefix (system prompt + tool definitions) and a dynamic trajectory (message history). Ablation shows that removing any component degrades the system markedly. The essence of the ReAct loop is appending to the trajectory, over and over, so the model keeps advancing the task.\n\n**Harness Is the Competitive Advantage**: Model capability is commoditizing; the real differentiator is the Harness—the constrain, verify, and correct mechanisms built around context and tools that enable reliable task completion. In production-grade Agent systems, the vast majority of Harness code goes into these safeguards, not the context and tools alone.\n\n**From Workflow to Autonomous Agent**: Prompts first, then workflows, autonomous Agents last—that ordering is the most practical way to reduce unexpected behavior. Every orchestration pattern has situations where it fits; no single pattern is best everywhere.\n\n**Security Is an Architectural Issue**: Guardrails, human-in-the-loop intervention, alignment (keeping the model's behavior consistent with human intent)—security has to be designed in from the first line of code, not patched on before launch. It spans five levels: model, context, tools, collaboration, and society.\n\nThe next chapter examines the Harness's most central component in depth: context engineering. Chapter 7 covers the Agent concept's academic roots in reinforcement learning and compares traditional RL with modern LLM Agents.\n\nThe thought questions below are designed to take the chapter's core concepts a level deeper.\n\n## Thought Questions\n\n1. ★★ If you could only add one capability to an Agent system—a stronger model, richer context, or more tools—which would you choose? Under what conditions would your choice change?\n2. ★★★ In the ReAct loop, each of the Agent's LLM calls receives the full history trajectory, so as the trajectory grows, the cost of this design grows quadratically. Can that quadratic growth be broken without losing critical information?\n3. ★★ The \"Model as Agent\" paradigm means models are becoming more autonomous in tool-calling decisions. However, this chapter argues that the importance of Harness engineering is actually increasing. How can these two trends coexist? Where does the future core value of Agent frameworks lie?\n4. ★★ In the ablation experiment, the absence of \"tool result feedback\" caused the Agent to fall into an infinite loop. In a production environment, besides missing tool results, what other situations could cause an Agent to loop? What detection and termination mechanisms would you design?\n5. ★ This chapter analyzed five Agent products along three dimensions: working context, action interfaces, and strategy. Pick an AI product you use daily, analyze it along the same three dimensions, and judge whether its architecture is appropriate. If you were designing it, what would you improve?\n6. ★★ If you were to design a customer service system specifically for booking flights, would you choose a workflow pattern or an autonomous Agent pattern? Is it possible to mix both patterns in the same system?\n7. ★★★ The guardrails section mentioned tool risk ratings. If a tool is generally low-risk but becomes high-risk with specific parameter combinations (e.g., `delete_file` deleting a normal file vs. deleting a system file), how would you design dynamic risk assessment?\n8. ★★ In the Agent product table in this chapter, all Agents have an \"open-ended\" action space. In what scenarios would a constrained action space (e.g., only being able to choose from predefined options) be superior to an open-ended one?\n9. ★★ The human-in-the-loop intervention mechanism requires the Agent to \"gracefully hand over control.\" However, in practice, the user might be offline, respond slowly, or give vague instructions. What should the Agent do in such cases?\n10. ★★★ The introduction states that \"good design principles should transcend model iteration cycles.\" Give an example of a current Agent design principle that you believe might become obsolete as models improve, and explain your reasoning.\n\n\nANONYMOUS CHINESE X:\n### 从Harness工程视角看[第9/9部分]AI代理入门\n\n从Harness工程的角度来看，本书的每一章都系统地构建了Harness的一个组成部分。与此同时，安全问题并不属于单一章节；它是贯穿整本书的跨领域关注点（跨领域关注点会同时涉及系统的多个部分，就像软件工程中的日志必须贯穿每个模块一样）。下表以单一视图呈现了Harness功能、安全方面及相应章节：\n\n| Harness关注点 | 对应章节 | 核心内容 | 安全关注点 |\n|--------------------|--------------------|-------------------------------|------------------------|\n| 上下文设计 | 第2章（上下文工程） | 提示工程、Agent状态栏、上下文压缩、Agent技能 | 提示注入和信息泄露 |\n|

|\n\nAnthropic在构建长期运行的Agent时的实践展示了Harness设计如何解决模型自身无法解决的问题。他们在“初始化Agent”（设置环境、分解任务列表）和“执行Agent”（每次会话逐步推进并留下清晰的交接工件）之间分配复杂任务，使用结构化的Harness来应对长任务的两种失败模式：上下文耗尽和过早宣告任务完成。接下来的章节将逐个介绍Harness组件——第2章从最核心的部分开始，即上下文工程，第5章阐述了编码Agent中Harness工程的完整实践。\n\n### 章节总结\n\n本章构建了一个以实践为导向的框架，用于理解和构建AI代理。\n\n**Agent = 推理引擎 + 工作上下文 + 行动接口**：大语言模型提供推理和决策，上下文提供决策时可用的工作信息集，工具提供行动接口。三者缺一不可。\n\n**扩展上下文和工具是主要的能力杠杆**：一旦模型固定，重新定义或扩大观察和行动空间——即扩展上下文和工具——通常可以直接将无法解决的任务转化为可解决的任务。从Manus到OpenClaw的演变表明，很多通用性来自于扩展接口边界；这种扩展必须按需进行，并与权限和验证相结合。\n\n**上下文是决定性因素**：上下文由静态前缀（系统提示 + 工具定义）和动态轨迹（消息历史）组成。消融实验表明，移除任何组件都会显著降低系统性能。ReAct循环的本质是不断向轨迹中追加内容，从而使模型不断推进任务。\n\n**Harness是竞争优势**：模型能力正在商品化；真正的差异化因素是Harness——围绕上下文和工具构建的约束、验证和纠正机制，能够实现可靠的任务完成。在生产级Agent系统中，绝大多数Harness代码都用于这些保障措施，而不仅仅是上下文和工具。\n\n**从工作流到自主Agent**：先有提示词，然后是工作流，最后是自主Agent——这种顺序是减少意外行为的最实用方式。每种编排模式都有其适用的情况；没有一种模式在所有地方都是最好的。\n\n**安全是架构问题**：护栏、人工参与、对齐（使模型行为与人类意图保持一致）——安全必须从代码的第一行开始设计，而不是在发布前修补。它涵盖五个层面：模型、上下文、工具、协作和社会。\n\n下一章将深入探讨Harness最核心的组件：上下文工程。第7章将介绍Agent概念在强化学习中的学术根源，并比较传统RL与现代LLM Agent。\n\n以下是针对本章核心概念进一步深入的思考问题。\n\n### 思考问题\n\n1. ★★ 如果只能给Agent系统添加一种能力——更强的模型、更丰富的上下文或更多工具，你会选择哪一种？在什么条件下你的选择会改变？\n2. ★★★ 在ReAct循环中，Agent的每次大语言模型调用都会接收完整的历史轨迹，因此随着轨迹增长，这种设计的成本呈二次方增长。能否在不丢失关键信息的情况下打破这种二次方增长？\n3. ★★ “模型即Agent”范式意味着模型在工具调用决策上变得更加自主。然而，本章认为Harness工程的重要性实际上在增加。这两种趋势如何共存？Agent框架的未来核心价值在哪里？\n4. ★★ 在消融实验中，缺少“工具结果反馈”导致Agent陷入无限循环。在生产环境中，除了缺少工具结果，还有哪些情况可能导致Agent循环？你会设计哪些检测和终止机制？\n5. ★ 本章从工作上下文、行动接口和策略三个维度分析了五种Agent产品。选择一个你日常使用的AI产品，从相同的三个维度进行分析，并判断其架构是否合适。如果由你设计，你会如何改进？\n6. ★★ 如果你要专门设计一个用于预订航班的客户服务系统，你会选择工作流模式还是自主Agent模式？是否可能在同一系统中混合使用这两种模式？\n7. ★★★ 护栏部分提到了工具风险评级。如果一个工具通常风险较低，但在特定参数组合下变得风险较高（例如`delete_file`删除普通文件与删除系统文件），你会如何设计动态风险评估？\n8. ★★ 在本章的Agent产品表中，所有Agent都有“开放式”行动空间。在什么场景下，受限行动空间（例如只能从预定义选项中选择）比开放式行动空间更优？\n9. ★★ 人工参与干预机制要求Agent“优雅地移交控制权”。然而，在实践中，用户可能离线、响应缓慢或给出模糊指示。这种情况下Agent应该怎么做？\n10. ★★★ 引言中提到“好的设计原则应该超越模型迭代周期”。给出一个你认为随着模型改进可能过时的当前Agent设计原则，并解释原因。\n\nANONYMOUS CHINESE Y:\n###
