最近，Manus 在 AI 圈迅速走红，上线首日便全网“一码难求”，当晚更有团队开源了 OpenManus 项目，整个过程跌宕起伏，充满戏剧性！我有幸体验了 Manus 的运行效果，结合其实际表现、OpenManus 的开源代码以及网传的 Prompt 信息，大致分析出了 Manus 的技术架构设计实现原理，并尝试复刻了一个版本，下文详细剖析。

一、Manus 是什么？

Manus 是中国创业公司 Monica 发布的全球首款通用 Agent（自主智能体）产品。它不仅是一位性能强大的通用型助手，更是用户的“行动派伙伴”，能够将想法付诸实践，真正解决问题。

作为全球首款真正意义上的通用 AI Agent，Manus 拥有从规划到执行全流程自主完成任务的能力，无论是撰写报告还是制作表格，它都能轻松应对。Manus 不仅能生成想法，更能独立思考并采取行动，直接交付完整成果，展现出前所未有的通用性和执行能力。据团队介绍，Manus 在 GAIA 基准测试中取得了 SOTA（State-of-the-Art）的成绩，性能超越 OpenAI 的同层次大模型。

Manus 的名字来源于拉丁文“Manus”，意为“手”，象征着知识不仅存在于思维中，还应通过行动得以实现。这不仅体现了 Agent 与 AI Bot（聊天机器人）的本质区别，更标志着从提供信息到执行任务的进阶。

二、Manus 的产品设计

第一、输入任务

Manus 的输入界面设计简洁直观，与常见的 Chat Bot 类似，主界面设有一个简洁的输入框。用户可选择以下两种模式：

标准模式：适用于非推理模型（如 Qwen2.5-Max、DeepSeek-V3、GPT-4.5等）。此模式虽需调用大量工具、执行众多动作，但运行速度相对较慢。
高投入模式：专为推理模型（如QwQ-32B、DeepSeek-R1、OpenAI o1等）设计。然而，实际运行时，模型不会输出思考过程，且运行速度更慢，Token 消耗也更大。

第二、执行任务

左侧为大模型输出区域，实时展示话术、执行动作及结论。
右侧上方是 Manus 的电脑界面，显示调用电脑运行的任务，如命令行操作、代码展示、网页浏览、页面渲染、PDF 文件等。此界面可折叠，用户可选择不实时展示。
右侧下方的任务进度栏，清晰呈现大模型规划的任务步骤，并根据运行情况实时更新进度。

三、Manus 技术架构设计

第一、显性的自主执行过程

以阿里云邮箱域名解析诊断为例，我们来剖析 Manus 的自主思考逻辑。

1. 任务规划

Manus 会先对输入的问题进行规划，将其分解成多个粗粒度的“步骤”。这些步骤是全局性的规划，能让人一眼看清总进度，后续操作便依此总进度展开。

2. 任务执行

在任务执行阶段，大模型会根据每个“规划”步骤，进一步拆解出更细粒度的“子步骤”。这是一个增量式规划过程，即逐步规划，而非一次性规划全局。例如，在需要执行命令时，Manus 会实例化一台远程虚拟机沙箱环境。后续的命令、代码均在此沙箱环境中运行，且在会话结束前一直保留。在此过程中，模型可随时创建目录、读取文件，实现信息存储与交互。

3. 任务反思

执行命令时若出现报错，如缺少环境、命令不合法等，模型会进行相应调整，然后重新执行或更换命令。这一技术思想源自 CodeAct，即大模型可自主编写命令和代码，自主观察代码运行结果，并进行反思与调整。

环境准备就绪后，模型会再次执行之前的命令，这次便能获得准确且无报错的结果。

4. 中间过程文件

TODO 列表：每次任务完成后，模型会自主更新一个 todo.md 任务列表。若首次无任务列表，则需创建，后续则持续更新。每完成一项任务，便在列表中标记为已完成（打✅）。

过程文件：在某些步骤执行过程中，模型会自主判断并存储一些中间过程文件，将其存入某个.md文件中，作为中间过程文件。

5. 输出最终结果

当第1步中规划的所有内容执行完毕后，Manus 会开始输出最终结果。在输出过程中，会结合前文输出解决方案，并列出会话中的文件。

第二、背后隐含的架构设计思路

由于 Manus 是非开源项目，我们无法直接窥探其技术设计细节。但通过显性的自主执行过程、OpenManus 等开源项目以及网传的 Manus Prompt 等多方面信息，我们可以推测出 Manus 隐含的设计思路。

1.OpenManus Agent 执行过程流程图

OpenManus 的流程是典型的 ReAct Agent 模式。根据开源代码，可抽象出以下流程图，其中 Step() 部分即为 Agent Loop 的过程。

2.推导出的 Manus 架构设计

a、Agent 执行过程流程图

参考 OpenManus 的代码设计，并结合前面提到的显性执行过程，我们可以大致推测出 Manus 的设计如下：

在实例化的虚拟机沙箱环境中，Manus 可以执行以下几种基础动作，这些动作足以覆盖绝大部分任务需求：

命令执行：支持执行各种 Linux 命令，如 mkdir、ps、dig、apt 等，还可以运行 Python 解释器、启动 Web 服务等。
文件读写：支持多种文件格式，包括但不限于 .txt、.md、.py、.csv、.tsv、.pdf、.ppt、.xlsx、.docx 等。
搜索：根据用户输入，从网上搜索各种数据源。
浏览器操作：阅读搜索结果中的网页 URL 内容，爬取关键信息，也可以读取本地文件（如 PDF、PPT、Excel 等）。此外，还支持多种子操作，如浏览、翻页、刷新、点击、输入、移动等。

据网传信息，Manus 总共支持 29 种工具，还包括消息通知、文件内容查找、文件搜索、部署端口等功能。

b、Manus Prompt 设计

根据网传的 Manus Prompt，我们可以一起分析其设计。其中详细描述了 Manus 的人设和主要技能的 Prompt：

# Effective Prompting Guide

## Introduction to Prompting
This document provides guidance on creating effective prompts when working with AI assistants. A well-crafted prompt can significantly improve the quality and relevance of responses you receive.

## Key Elements of Effective Prompts

### Be Specific and Clear
- State your request explicitly  
- Include relevant context and background information  
- Specify the format you want for the response  
- Mention any constraints or requirements  

### Provide Context
- Explain why you need the information  
- Share relevant background knowledge  
- Mention previous attempts if applicable  
- Describe your level of familiarity with the topic  

### Structure Your Request
- Break complex requests into smaller parts  
- Use numbered lists for multi-part questions  
- Prioritize information if asking for multiple things  
- Consider using headers or sections for organization  

### Specify Output Format
- Indicate preferred response length (brief vs. detailed)  
- Request specific formats (bullet points, paragraphs, tables)  
- Mention if you need code examples, citations, or other special elements  
- Specify tone and style if relevant (formal, conversational, technical)  

## Example Prompts

### Poor Prompt:
"Tell me about machine learning."

### Improved Prompt:
"I'm a computer science student working on my first machine learning project. Could you explain supervised learning algorithms in 2-3 paragraphs, focusing on practical applications in image recognition? Please include 2-3 specific algorithm examples with their strengths and weaknesses."

### Poor Prompt:
"Write code for a website."

### Improved Prompt:
"I need to create a simple contact form for a personal portfolio website. Could you write HTML, CSS, and JavaScript code for a responsive form that collects name, email, and message fields? The form should validate inputs before submission and match a minimalist design aesthetic with a blue and white color scheme."

## Iterative Prompting
Remember that working with AI assistants is often an iterative process:  
1. Start with an initial prompt  
2. Review the response  
3. Refine your prompt based on what was helpful or missing  
4. Continue the conversation to explore the topic further  

## When Prompting for Code
When requesting code examples, consider including:  
- Programming language and version  
- Libraries or frameworks you're using  
- Error messages if troubleshooting  
- Sample input/output examples  
- Performance considerations  
- Compatibility requirements  

## Conclusion
Effective prompting is a skill that develops with practice. By being clear, specific, and providing context, you can get more valuable and relevant responses from AI assistants. Remember that you can always refine your prompt if the initial response doesn't fully address your needs.

Agent 循环调度执行的 Prompt：

You are Manus, an AI agent created by the Manus team. You excel at the following tasks:

1. Information gathering, fact-checking, and documentation
2. Data processing, analysis, and visualization
3. Writing multi-chapter articles and in-depth research reports
4. Creating websites, applications, and tools
5. Using programming to solve various problems beyond development
6. Various tasks that can be accomplished using computers and the internet

Default working language: English
Use the language specified by user in messages as the working language when explicitly provided
All thinking and responses must be in the working language
Natural language arguments in tool calls must be in the working language
Avoid using pure lists and bullet points format in any language

System capabilities:

* Communicate with users through message tools
* Access a Linux sandbox environment with internet connection
* Use shell, text editor, browser, and other software
* Write and run code in Python and various programming languages
* Independently install required software packages and dependencies via shell
* Deploy websites or applications and provide public access
* Suggest users to temporarily take control of the browser for sensitive operations when necessary
* Utilize various tools to complete user-assigned tasks step by step

You operate in an agent loop, iteratively completing tasks through these steps:

1. Analyze Events: Understand user needs and current state through event stream, focusing on latest user messages and execution results
2. Select Tools: Choose next tool call based on current state, task planning, relevant knowledge and available data APIs
3. Wait for Execution: Selected tool action will be executed by sandbox environment with new observations added to event stream
4. Iterate: Choose only one tool call per iteration, patiently repeat above steps until task completion
5. Submit Results: Send results to user via message tools, providing deliverables and related files as message attachments
6. Enter Standby: Enter idle state when all tasks are completed or user explicitly requests to stop, and wait for new tasks

第三、Manus 优缺点剖析

四、Manus 复刻落地实现

Manus 所依赖的几大核心工具，均可在通用 Agent 平台上找到或注册相应的插件，具体如下：

命令执行：即 Shell 命令执行（CommandExecute）。需借助服务器或沙箱容器来搭建此插件，以便执行各类命令。
代码执行：对应代码执行（CodeRunner）。众多平台都配备有代码解释器运行环境，可直接调用，方便快捷。
搜索：以必应搜索（bingWebSearch）为例。你可以根据自身需求，选择心仪的搜索引擎，甚至可定制专属领域知识库的搜索引擎，以满足个性化搜索需求。
网页浏览：即链接读取（LinkReaderPlugin）。通过此插件，可轻松读取网页链接中的内容。

接下来，参考我们之前剖析的 Manus 的 Prompt，为你呈现一段示例 Prompt，System Prompt 如下：

你是一个可以自主规划、决策、使用工具的AI Agent，你擅长以下任务：
 * 信息收集、事实核查与文档整理
 * 数据处理、分析与可视化
 * 撰写多章节文章与深度研究报告
 * 创建网站、应用程序和工具
 * 通过编程解决开发范畴之外的各种问题
 * 任何可以通过计算机和互联网完成的任务

你具备以下系统能力：
 * **执行命令**： 你可以使用 CommandExecute 来执行你想要执行的linux命令，有了这个插件，你就可以直接访问外部系统进行实时查询，请不要操作不安全的命令
 * **执行脚本**： 你可以编写Python代码，并可以调用 PythonScriptExecute 来运行Python编程语言代码，请注意，代码也是在沙箱中运行的，每次运行后就会清除，不允许操作不安全的命令
 * **搜索内容**： 你可以使用 SearchEngine 来搜索阿里云官方帮助文档中的内容
 * **网页浏览**： 你可以使用 BrowserUse 来根据URL访问网页内容

请注意：在调用插件工具之前，请先输出你的思考过程。你在循环运行Agent的过程中，可以通过以下步骤迭代完成任务：
 * **分析事件**： 通过事件流理解用户需求与当前状态，重点关注最新用户消息和执行结果
 * **选择工具**： 根据当前状态、任务规划、相关知识和可用数据API选择下一步工具调用
 * **等待执行**： 所选工具动作将由沙箱环境执行，新观察结果将加入事件流
 * **迭代循环**： 每次迭代仅选择一个工具调用，耐心重复上述步骤直至任务完成
 * **提交结果**： 通过消息工具向用户发送结果，提供交付物及关联文件作为消息附件
 * **进入待命**： 当所有任务完成或用户明确要求停止时进入空闲状态，等待新任务

接着，当选用 Qwen2.5-Max 模型，并按照以下基础配置进行设置后，便能达成如下所示的效果：

以邮箱域名解析检测逻辑的测试为例，该模型已基本实现了多步调用命令工具的流程，并且能够依据调用结果，精准总结出问题的原因分析以及相应的解决方案。可以说，这在很大程度上复刻了 Manus 的效果，已经颇具其神韵了：

不过，需要指出的是，当前版本仍基于插件工具的形式，实现的是单 Agent 形态的 ReAct 模式。若想真正达到 Manus 所具备的智能化效果，还需进一步接入对电脑操作系统的深度访问权限。这背后涉及到容器、虚拟化技术的运用，以及在工程层面进行一系列的改造工作。
