+
+# Plugin Development Standards
+
+## Strict Requirements for New Independent Plugins
+
+When creating **new independent plugins** (e.g., newly implemented wasm plugins or golang-filter plugins), you **MUST** follow these standards:
+
+### 1. Design Documentation Directory Requirements
+
+- You **MUST** create a `design/` directory within the plugin directory
+- Directory structure example:
+  ```
+  plugins/wasm-go/extensions/my-new-plugin/
+    ├── design/
+    │   ├── design-doc.md          # Design document
+    │   ├── architecture.md         # Architecture (optional)
+    │   └── requirements.md         # Requirements (optional)
+    ├── main.go
+    ├── go.mod
+    └── README.md
+  ```
+
+### 2. Design Documentation Content Requirements
+
+The design documentation in the `design/` directory should include:
+
+- **Plugin Purpose and Use Cases**: Clearly explain what problem the plugin solves
+- **Core Functionality Design**: Detailed description of main features and implementation approach
+- **Configuration Parameters**: List all configuration items and their meanings
+- **Technology Selection and Dependencies**: Explain the technology stack and third-party libraries used
+- **Boundary Conditions and Limitations**: Define the applicable scope and limitations of the plugin
+- **Testing Strategy**: How to verify plugin functionality
+
+### 3. Documentation Provided to AI Coding Tools
+
+If you are using AI Coding tools (such as Cursor, GitHub Copilot, etc.) to generate code:
+
+- You **MUST** save the complete design documents, requirement descriptions, and prompts you provided to the AI in the `design/` directory
+- Recommended file naming:
+  - `ai-prompts.md` - AI prompts record
+  - `design-doc.md` - Complete design document
+  - `requirements.md` - Feature requirements list
+
+### 4. Files NOT to Commit to Git
+
+Note: The following files should **NOT** be committed to Git:
+- AI Coding tool work summary documents (should be placed in PR description)
+- Temporary feature change summary documents
+
+Design documents in the `design/` directory **SHOULD** be committed to Git, as they serve as the design basis and technical documentation for the plugin.
+
+## Examples
+
+### Good Plugin Directory Structure Example
+
+```
+plugins/wasm-go/extensions/ai-security-guard/
+  ├── design/
+  │   ├── design-doc.md          # ✅ Detailed design document
+  │   ├── ai-prompts.md          # ✅ Prompts provided to AI
+  │   └── architecture.png        # ✅ Architecture diagram
+  ├── main.go
+  ├── config.go
+  ├── README.md
+  └── go.mod
+```
+
+### Design Document Template
+
+When creating `design/design-doc.md`, you can refer to the following template:
+
+```markdown
+# [Plugin Name] Design Document
+
+## Overview
+- Plugin purpose
+- Problem it solves
+- Target users
+
+## Functional Design
+### Core Feature 1
+- Feature description
+- Implementation approach
+- Key code logic
+
+### Core Feature 2
+...
+
+## Configuration Parameters
+| Parameter | Type | Required | Description | Default |
+|-----------|------|----------|-------------|---------|
+| ...       | ...  | ...      | ...         | ...     |
+
+## Technical Implementation
+- Technology selection
+- Dependencies
+- Performance considerations
+
+## Test Plan
+- Unit tests
+- Integration tests
+- Boundary tests
+
+## Limitations and Notes
+- Known limitations
+- Usage recommendations
+```
+
+## Execution Checklist
+
+When creating a new plugin, please confirm:
+
+- [ ] Created `design/` directory within the plugin directory
+- [ ] Placed design documentation in the `design/` directory
+- [ ] If using AI Coding tools, saved prompts/requirement documents in the `design/` directory
+- [ ] Prepared AI Coding tool work summary (for PR description)
+- [ ] Design documentation is complete with necessary technical details
+
+## Tips
+
+- Design documentation is important technical documentation for the plugin, helpful for:
+  - Understanding design intent during code review
+  - Quickly understanding implementation approach during future maintenance
+  - Learning and reference for other developers
+  - Tracing the reasoning behind design decisions

 PR 是更改 Higress 项目文件的唯一方法。为了帮助审查人更好地理解你的目的，PR 描述不能太详细。我们鼓励贡献者遵循 [PR 模板](./.github/PULL_REQUEST_TEMPLATE.md) 来完成拉取请求。
 
+#### 使用 AI Coding 工具的特殊要求
+
+如果你使用 AI Coding 工具（如 Cursor、GitHub Copilot 等）来生成 PR，我们有以下**严格要求**：
+
+**针对新增独立插件的场景**（例如新实现的 wasm 插件或 golang-filter 插件）：
+- 你**必须**在插件目录下创建 `design/` 目录
+- 将你提供给 AI Coding 工具的设计文档放在 `design/` 目录中
+- 在 PR 描述中提供 AI Coding 工具生成的工作总结
+
+**针对日常更新/修改的场景**：
+- 在 PR 描述中提供你给 AI Coding 工具的提示词/指令
+- 在 PR 描述中提供 AI Coding 工具生成的工作总结
+
+**AI Coding 工作总结应包括**：
+- 做出的关键决策
+- 实现的主要更改
+- 重要的注意事项或限制
+
+**Review 优先级说明**：
+- 如果你使用了 AI Coding 工具但没有按照上述要求操作，你的 PR review 优先级将会**降低**
+- 我们**无法保证**对不符合要求的 AI Coding PR 进行及时 review
+- 如果不是使用 AI Coding 工具完成的 PR，则不需要遵循这些额外要求
+
+这些要求的目的是确保使用 AI 生成的代码具有充分的文档记录和可追溯性，便于代码审查和后续维护。通过要求提供提示词/设计文档，我们可以更好地理解开发意图和上下文。

 PR is the only way to make change to Higress project files. To help reviewers better get your purpose, PR description could not be too detailed. We encourage contributors to follow the [PR template](./.github/PULL_REQUEST_TEMPLATE.md) to finish the pull request.
 
+#### Special Requirements for AI Coding Tool Usage
+
+If you use AI Coding tools (such as Cursor, GitHub Copilot, etc.) to generate PRs, we have the following **strict requirements**:
+
+**For new standalone plugin scenarios** (e.g., newly implemented wasm plugins or golang-filter plugins):
+- You **MUST** create a `design/` directory under the plugin directory
+- Place the design document you provided to the AI Coding tool in the `design/` directory
+- Provide an AI Coding summary in the PR description
+
+**For regular updates/changes scenarios**:
+- Provide the prompts/instructions you gave to the AI Coding tool in the PR description
+- Provide an AI Coding summary in the PR description
+
+**AI Coding Summary should include**:
+- Key decisions made
+- Major changes implemented
+- Important considerations or limitations
+
+**Review Priority Notice**:
+- If you use AI Coding tools but do not follow the above requirements, your PR review priority will be **lowered**
+- We **cannot guarantee** timely reviews for AI Coding PRs that do not meet these requirements
+- If the PR is not completed using AI Coding tools, these additional requirements do not apply
+
+The purpose of these requirements is to ensure that AI-generated code is adequately documented and traceable, facilitating code review and subsequent maintenance. By requiring prompts/design documents, we can better understand the development intent and context.

+#### AI Coding ツール使用時の特別な要件
+
+AI Coding ツール（Cursor、GitHub Copilot など）を使用して PR を生成する場合、以下の**厳格な要件**があります：
+
+**新規独立プラグインのシナリオ**（新しく実装された wasm プラグインや golang-filter プラグインなど）の場合：

+- PR の説明に AI Coding サマリーを提供してください
+
+**AI Coding サマリーには以下を含める必要があります**：
+- 行われた重要な決定
+- 実装された主要な変更
+- 重要な考慮事項または制限事項
+
+**レビュー優先度に関する通知**：
+- AI Coding ツールを使用したが上記の要件に従わなかった場合、PR のレビュー優先度が**低下**します
+- 要件を満たしていない AI Coding PR に対して、タイムリーなレビューを**保証できません**
+- AI Coding ツールを使用せずに完了した PR の場合、これらの追加要件は適用されません
+
+これらの要件の目的は、AI で生成されたコードが十分に文書化され、追跡可能であることを保証し、コードレビューと後続のメンテナンスを容易にすることです。プロンプト/設計ドキュメントを要求することで、開発意図とコンテキストをより良く理解できます。

 - WasmPlugin Controller：监听 WasmPlugin 资源，将 Higress WasmPlugin 转化为 Istio WasmPlugin。Higress WasmPlugin 在 Istio WasmPlugin 的基础上进行了扩展，支持全局、路由、域名、服务级别的配置。
