+> **DEPRECATED**: This license is no longer in effect. Please refer to the [LICENSE](LICENSE) file for current licensing terms.
+
+# Commercial License for Yao
+
+This document outlines the terms for the commercial license of the **Yao** project. While the Yao project is primarily licensed under the **Apache License, Version 2.0**, certain commercial use cases require a separate commercial license.
+
+## 1. Commercial License Requirements
+
+The following use cases require a commercial license:
+
+1. **Application Hosting Services**  
+   If you use Yao, or any derivative product (such as a forked or modified version of Yao), to provide Yao-based application hosting services (e.g., Software-as-a-Service (SaaS) or Platform-as-a-Service (PaaS)) to users, you must obtain a commercial license. This restriction applies regardless of whether the original Yao code or a modified version is used to host and manage applications on behalf of third-party users for commercial purposes.  
+   **In addition**, if you provide hosting services for applications that are built using Yao (even if they are customized or modified versions of Yao), a commercial license is required.
+
+   ### Definition: Application Hosting Services
+
+   "Application Hosting Services" refers to any service that involves hosting Yao-based applications or web applications created with Yao (including modified versions of Yao) for third-party users. This includes, but is not limited to:
+
+   - **Hosting platforms** providing software or services built on top of Yao for third-party users.
+   - **SaaS or PaaS offerings** where you manage and host applications that are based on or utilize Yao, either in their original or modified form.
+   - **Managed hosting services** where Yao is used as the underlying technology for applications deployed for external clients.
+
+   In these cases, a commercial license is required, whether you are using the original Yao code or a fork/modified version.
+
+2. **AI Web Application Generation Services**  
+   If you provide services that generate AI-driven web applications using Yao, or any derivative product (such as a fork or modified version of Yao), to third-party users, you are required to purchase a commercial license.
+
+   ### Definition: AI Web Application Generation Services
+
+   "AI Web Application Generation Services" refers to any service or functionality that utilizes Yao (or any forked or modified version of Yao) to automate the creation of web applications with AI capabilities. This includes, but is not limited to, providing third-party users with:
+
+   - **Automated web application development** driven by AI, where the service generates complete or partial web applications.
+   - **Customizable web solutions** that are powered by AI and built using Yao as the core technology.
+   - **On-demand application generation** for specific client needs, using Yao to dynamically build, configure, or deploy applications for users.
+
+   In these cases, whether Yao is directly used, forked, or modified, a commercial license is required to operate legally.
+
+## 2. Use Under Apache License 2.0
+
+For all other uses, the **Apache License, Version 2.0** applies. You are free to use, modify, and distribute the Yao project under the terms of Apache 2.0 as long as your usage does not fall within the restricted scenarios outlined above.
+
+## 3. Obtaining a Commercial License
+
+To inquire about or obtain a commercial license, please contact us at:
+
+- **Email**: [friends@iqka.com]
+- **Website**: [https://moapi.ai/contact]
+
+Pricing and terms for commercial licenses vary based on usage scenarios, user scale, and other factors.
+
+## 4. Compliance and Auditing
+
+If you have any questions about whether your use case requires a commercial license, please contact us for clarification. We reserve the right to audit usage for compliance and enforce commercial licensing terms where necessary.
+

-## How It Works
+## What Makes Yao Different?

-Think of Yao Agent as a **cage, not an animal**. What you put inside determines the behavior; the cage keeps it controlled.
+| Traditional AI Assistants     | Yao Autonomous Agents                 |
+| ----------------------------- | ------------------------------------- |
+| Entry point: Chatbox          | Entry point: Email, Events, Schedules |
+| Passive: You ask, they answer | Proactive: They work autonomously     |
+| Role: Tool                    | Role: Team member                     |

-Every request flows through the same pipeline:
-
-![Pipeline](docs/pipeline.png)
-
-`Create Hook` runs before the executor — inject context, enforce constraints, route requests.  
-`Next Hook` runs after — validate output, trigger downstream actions, drive multi-step loops.  
-**The AI does the heavy lifting. You define the boundaries.**
-
-### Three Modes
-
-| Mode | Executor | When to use |
-|------|----------|-------------|
-| **LLM** | OpenAI, Anthropic, etc. | Conversational assistants, Q&A, content generation |
-| **CLI Agent** | OpenCode, Claude Code, Codex in a container | Computer use, sandbox isolation, SKILL ecosystem |
-| **Pure Hook** | Your own TypeScript code | Deterministic logic, routing, menu flows — no AI needed |
-
-All three share the same Hook interface. You can mix them freely — route some requests through the LLM, handle others with pure code, all inside a single `Create Hook`.
+> The entry point is not a chatbox — it's email, events, and scheduled tasks.

 ---

 ## Features

-### Agent Framework
+### Autonomous Agent Framework

- **TypeScript Hooks** — `Create` and `Next` hooks intercept every request; built-in V8 engine
- **Native MCP Support** — Connect tools via process, SSE, or STDIO transport

- **Multi-Agent** — Delegate to specialist agents or call agents in parallel
- **CLI Agent / Sandbox** — Run Claude Code (or other CLI runners) in an isolated container with VNC desktop support
- **Skills Ecosystem** — Drop reusable capability packs (`SKILL.md`) into any CLI Agent
+Build agents that work like real team members:
+
+- **Three Trigger Modes** — Clock (scheduled), Human (email/message), Event (webhook/database)
+- **Six-Phase Execution** — Inspiration → Goals → Tasks → Run → Deliver → Learn
+- **Multi-Agent Orchestration** — Agents delegate, collaborate, and compose dynamically
+- **Continuous Learning** — Agents accumulate experience in private knowledge bases
+
+### Native MCP Support

-## About the Name
-
-Yao (爻, yáo) is the fundamental symbol in the I Ching — the building block of the eight trigrams. Like a binary digit, it has two states. Their combinations describe the patterns of everything.
+- **All-in-One** — Data, API, Agent, UI in one engine
+- **TypeScript Support** — Built-in V8 engine
+- **Single Binary** — No Node.js, Python, or containers required
+- **Edge-Ready** — Runs on ARM64/x64 devices

+YAO 是一款开源应用引擎，使用 Golang 编写，以一个命令行工具的形式存在, 下载即用。适合用于开发业务系统、网站/APP API 接口、管理后台、自建低代码平台等。

-## 工作原理
+YAO 采用 flow-based 的编程模式，通过编写 YAO DSL (JSON 格式逻辑描述) 或使用 JavaScript 编写处理器，实现各种功能。 YAO DSL 可以有多种编写方式:

-Yao Agent 本质上是一个**笼子，而不是动物**。放进去的东西决定行为，笼子保证可控。
+1. 纯手工编写

-每个请求都经过同一套管道：
+2. 使用自动化脚本，根据上下文逻辑生成

-![Pipeline](docs/pipeline.png)
+3. 使用可视化编辑器，通过“拖拉拽”制作

-`Create Hook` 在执行器前运行 —— 注入上下文、施加约束、路由请求。  
-`Next Hook` 在执行器后运行 —— 校验输出、触发下游动作、驱动多步循环。  
-**AI 负责干活，你来划定边界。**
+官网: [https://yaoapps.com](https://yaoapps.com)

-### 三种模式
+文档: [https://yaoapps.com/doc](https://yaoapps.com/doc)

-| 模式 | 执行器 | 适用场景 |
-|------|--------|---------|
-| **LLM** | OpenAI、Anthropic 等 | 对话助手、问答、内容生成 |
-| **CLI Agent** | 容器中的 OpenCode、Claude Code、Codex | Computer Use、沙箱隔离、SKILL 生态 |
-| **纯 Hook** | 你自己的 TypeScript 代码 | 确定性逻辑、菜单路由、无需 AI 的业务流程 |
+## 最新版本下载安装 (推荐)

-三种模式共享同一套 Hook 接口，可以自由混合 —— 在一个 `Create Hook` 里，部分请求走 LLM，部分用纯代码处理。
+https://github.com/YaoApp/xgen-dev-app

+## 演示

-## 功能特性
+![界面](docs/yao-setup-demo.jpg)

-### Agent 框架
+使用 YAO 开发的应用

- **TypeScript Hook** — `Create` 和 `Next` 两个钩子拦截每一次请求；内置 V8 引擎
- **原生 MCP 支持** — 通过 process、SSE 或 STDIO 传输协议接入工具
- **Memory API** — 四个作用域：请求级、会话级、用户级、团队级
- **多 Agent 协作** — 委派给专属 Agent 或并行调用多个 Agent
- **CLI Agent / 沙箱** — 在隔离容器中运行 Claude Code 等 CLI 程序，支持 VNC 桌面
- **Skills 生态** — 将可复用的能力包（`SKILL.md`）挂载到任意 CLI Agent

-### 全栈运行时
+## 介绍

-一个二进制文件包含所有能力：
+Yao 是一个只需使用 JSON 即可创建数据库模型、编写 API 接口、描述管理后台界面的应用引擎，使用 Yao 构建的应用可运行在云端或物联网设备上。 开发者不需要写一行代码，就可以拥有 10 倍生产力。

- **数据模型** — 用 JSON/YAML 定义数据库表和关联关系
- **REST API** — 将路由映射到模型查询或 TypeScript 处理器
- **SUI 页面** — 组件化 Web UI，支持服务端渲染
- **Chat UI（CUI）** — 内置对话界面，开箱即用
- **TypeScript** — 内置 V8 引擎，不依赖 Node.js
- **单一二进制** — 支持 ARM64/x64，宿主机无需 Python、Node 或容器
+Yao 基于 **flow-based** 编程思想，采用 **Go** 语言开发，支持多种方式扩展数据流处理器。这使得 Yao 具有极好的**通用性**，大部分场景下可以代替编程语言, 在复用性和编码效率上是传统编程语言的 **10 倍**；应用性能和资源占比上优于 **PHP**, **JAVA** 等语言。

-### 内置搜索
+Yao 内置了一套数据管理系统，通过编写 **JSON** 描述界面布局，即可实现 90% 常见界面交互功能，特别适合快速制作各类管理后台、CRM、ERP 等企业内部系统。对于特殊交互功能亦可通过编写扩展组件或 HTML 页面的方式实现。内置管理系统与 Yao 并不耦合，亦可采用 **VUE**, **React** 等任意前端技术实现管理界面。

- **向量搜索** — 支持 OpenAI 或 FastEmbed 嵌入模型
- **知识图谱** — 实体关系检索
- **GraphRAG** — 向量 + 图谱混合搜索
+## 安装
