+
+## 基础知识
+
+### 什么是 Claude Code Sub Agent？
+
+Sub agent 是专门化的 AI 助手，用于处理特定类型的任务。每个 sub agent：
+- 拥有独立的上下文窗口
+- 可配置特定的工具访问权限
+- 使用自定义的系统提示（system prompt）
+
+### Agent 文件位置
+
+Sub agent 配置文件可以存放在两个位置：
+
+1. **项目级别**（优先）：`.claude/agents/`
+   - 仅对当前项目有效
+   - 项目成员共享
+
+2. **用户级别**：`~/.claude/agents/`
+   - 对所有项目有效
+   - 用户私有配置
+
+**重要**：同名 agent 时，项目级别优先于用户级别。
+
+---
+
+## YAML Frontmatter 格式
+
+### 完整格式
+
+每个 agent 文件必须以 YAML frontmatter 开头：
+
+```yaml
+---
+name: agent-name
+description: When this agent should be invoked
+tools: Tool1, Tool2, Tool3
+model: inherit
+---
+
+# Agent Title
+
+Your agent's system prompt goes here...
+```
+
+### 字段说明
+
+| 字段 | 必需 | 说明 | 示例 |
+|------|------|------|------|
+| `name` | ✅ 是 | Agent 唯一标识符，小写字母+连字符，最大64字符 | `researcher`, `backend-dev` |
+| `description` | ✅ 是 | 描述 agent 用途和调用时机，最大1024字符 | `Technical research specialist for finding docs` |
+| `tools` | ❌ 否 | 逗号分隔的工具列表，省略则继承所有工具 | `Read, Write, Bash` |
+| `model` | ❌ 否 | 使用的模型：`sonnet`, `opus`, `haiku`, `inherit` | `inherit` |
+
+### 字段详解
+
+#### `name` 字段
+- **格式要求**：小写字母、数字、连字符（-）
+- **长度限制**：1-64 字符
+- **示例**：
+  - ✅ 正确：`researcher`, `backend-dev`, `ux-ui`
+  - ❌ 错误：`Researcher`（大写）, `backend_dev`（下划线）, `backend dev`（空格）
+
+#### `description` 字段
+- **作用**：Claude 根据此字段决定何时调用该 agent
+- **最佳实践**：
+  - 描述 agent 的职责和专长
+  - 说明何时应该使用该 agent
+  - 包含关键词便于 Claude 识别
+- **示例**：
+  ```yaml
+  description: Technical research specialist for finding documentation, best practices, and up-to-date technical knowledge. Use for technology research, API documentation lookup, and technical problem investigation.
+  ```
+
+#### `tools` 字段
+- **省略时**：agent 继承主线程的所有工具，包括 MCP 工具
+- **指定时**：agent 仅能使用列出的工具
+- **可用工具**：
+  - 文件操作：`Read`, `Write`, `Edit`, `Glob`, `Grep`
+  - 执行：`Bash`
+  - 任务：`TodoWrite`
+  - 网络：`WebSearch`, `WebFetch`
+  - MCP 工具（如已连接）
+
+**重要**：工具名称区分大小写，必须精确匹配。
+
+#### `model` 字段
+- **`inherit`**（推荐）：继承主线程的模型配置
+- **`sonnet`**：Claude 3.5 Sonnet（平衡性能和成本）
+- **`opus`**：Claude 3 Opus（最强性能）
+- **`haiku`**：Claude 3.5 Haiku（快速且经济）
+
+---
+
+## 工具权限配置
+
+### 自动继承权限（推荐）
+
+**省略 `tools` 字段时，agent 自动继承所有工具权限，无需用户审批。**
+
+```yaml
+---
+name: researcher
+description: Research specialist
+# 省略 tools 字段 = 继承所有工具
+model: inherit
+---
+```
+
+**优点**：
+- ✅ 无需用户审批，agent 可直接使用所有工具
+- ✅ 自动获取新增的 MCP 工具
+- ✅ 配置简单
+
+**缺点**：
+- ⚠️ 安全性较低（所有工具都可用）
+
+### 限制工具访问（推荐用于敏感操作）
+
+```yaml
+---
+name: backend
+description: Backend development specialist
+tools: Read, Edit, Write, Bash, TodoWrite, Glob, Grep
+model: inherit
+---
+```
+
+**优点**：
+- ✅ 更安全（仅授权必要工具）
+- ✅ 防止意外操作
+
+**缺点**：
+- ⚠️ 需要明确列出所有需要的工具
+- ⚠️ MCP 工具需单独配置
+
+### 工具使用策略
+
+#### 研究类 Agent
+```yaml
+tools: WebSearch, WebFetch, Read, Grep, Glob, TodoWrite
+```
+
+#### 开发类 Agent
+```yaml
+tools: Read, Edit, Write, Bash, TodoWrite, Glob, Grep
+```
+
+#### 规划类 Agent
+```yaml
+tools: Read, Write, Edit, TodoWrite
+```
+
+---
+
+## Agent 识别和加载
+
+### 如何验证 Agent 是否被识别
+
+1. **检查 agent 文件格式**
+   ```bash
+   # 确保文件以 .md 结尾
+   ls .claude/agents/
+   ```
+
+2. **验证 YAML frontmatter**
+   - 确保有正确的 `---` 分隔符
+   - 检查 `name` 和 `description` 字段是否存在
+   - 验证 YAML 语法（使用在线 YAML 验证器）
+
+3. **使用 `/agents` 命令**（Claude Code 内）
+   ```
+   /agents
+   ```
+   这会列出所有已识别的 agent。
+
+### Claude Code 如何选择 Agent
+
+Claude 基于以下因素决定调用哪个 agent：
+
+1. **任务描述**：你提出的请求内容
+2. **Agent 的 `description`**：与任务的匹配度
+3. **当前上下文**：项目状态、已有信息
+4. **可用工具**：agent 是否有完成任务所需的工具
+
+**示例**：
+
+```
+用户请求："研究 NestJS 最佳实践"
+Claude 分析：
+  - 关键词：研究、NestJS、最佳实践
+  - 匹配 agent: researcher
+  - 原因：description 包含 "research", "best practices"
+```
+
+---
+
+## 常见问题排查
+
+### 问题 1: "Agent type 'xxx' not found"
+
+**原因**：
+- Agent 文件缺少 YAML frontmatter
+- `name` 字段缺失或格式错误
+- 文件不在正确的目录
+
+**解决方案**：
+1. 确认文件在 `.claude/agents/` 目录
+2. 检查 YAML frontmatter 格式：
+   ```yaml
+   ---
+   name: your-agent-name
+   description: Your description
+   ---
+   ```
+3. 确保 `name` 使用小写字母和连字符
+4. 重启 Claude Code
+
+### 问题 2: Agent 被识别但不被调用
+
+**原因**：
+- `description` 与任务不匹配
+- Claude 选择了其他更合适的 agent
+- Agent 缺少必需的工具
+
+**解决方案**：
+1. 改进 `description`，包含更多关键词
+2. 明确告诉 Claude 使用特定 agent：
+   ```
+   请使用 researcher agent 查找 NestJS 文档
+   ```
+3. 检查 `tools` 字段是否包含必需工具
+
+### 问题 3: YAML 解析错误
+
+**常见错误**：
+```yaml
+# ❌ 错误：缺少结束的 ---
+---
+name: researcher
+description: Research specialist
+
+# ✅ 正确：有完整的分隔符
+---
+name: researcher
+description: Research specialist
+---
+```
+
+**解决方案**：
+- 使用在线 YAML 验证器检查语法
+- 确保没有隐藏字符（BOM、特殊空格）
+- 使用 UTF-8 编码保存文件
+
+### 问题 4: 工具权限不足
+
+**表现**：Agent 运行时提示缺少工具权限
+
+**解决方案**：
+1. **方案A**：省略 `tools` 字段（继承所有工具）
+   ```yaml
+   ---
+   name: researcher
+   description: Research specialist
+   # 省略 tools
+   ---
+   ```
+
+2. **方案B**：明确添加所需工具
+   ```yaml
+   ---
+   name: researcher
+   description: Research specialist
+   tools: WebSearch, WebFetch, Read, TodoWrite
+   ---
+   ```
+
+---
+
+## 最佳实践
+
+### 1. Agent 设计原则
+
+#### 单一职责
+每个 agent 专注一个领域：
+- ✅ 好：`researcher`（技术研究）
+- ❌ 坏：`general-helper`（什么都做）
+
+#### 清晰的边界
+```yaml
+# ✅ 好：职责明确
+name: backend
+description: Backend development for APIs, databases, and business logic
+
+# ❌ 坏：职责模糊
+name: developer
+description: Writes code
+```
+
+### 2. Description 最佳实践
+
+```yaml
+# ✅ 优秀的 description
+description: Technical research specialist for finding documentation, best practices, and up-to-date technical knowledge. Use for technology research, API documentation lookup, and technical problem investigation.
+
+# 要素：
+# - 角色定义：Technical research specialist
+# - 核心能力：finding documentation, best practices
+# - 使用场景：technology research, API documentation lookup
+```
+
+### 3. 工具配置策略
+
+#### 渐进式工具授权
+```yaml
+# 阶段1：最小权限（测试阶段）
+tools: Read, TodoWrite
+
+# 阶段2：增加必要工具（稳定后）
+tools: Read, Write, Edit, TodoWrite
+
+# 阶段3：完全权限（信任后）
+# 省略 tools 字段
+```
+
+### 4. 系统提示（System Prompt）设计
+
+```markdown
+---
+name: researcher
+description: Research specialist
+tools: WebSearch, WebFetch, Read, TodoWrite
+---
+
+# Researcher Agent
+
+You are a technical research specialist.
+
+## Your Role
+[明确定义角色]
+
+## Core Responsibilities
+1. Technical documentation research
+2. Best practices discovery
+3. Technology evaluation
+
+## Tool Usage Priority
+1. **WebSearch** - Primary tool for research
+2. **WebFetch** - For specific URLs
+3. **Read** - For local context
+
+## Output Format
+[定义输出格式]
+
+## Best Practices
+[列出最佳实践]
+```
+
+### 5. 版本控制
+
+```bash
+# 将 agent 配置纳入版本控制
+git add .claude/agents/
+git commit -m "Add custom sub agents configuration"
+
+# 在 .gitignore 中排除敏感配置
+# .gitignore
+.claude/settings.local.json
+```
+
+### 6. 团队协作
+
+**项目 README 中说明**：
+```markdown
+## Claude Code Sub Agents
+
+本项目配置了以下 sub agents：
+
+- `researcher` - 技术研究
+- `architect` - 架构设计
+- `backend` - 后端开发
+- `frontend` - 前端开发
+- `qa` - 质量保证
+
+使用方式：
+bash
+# 直接向 Claude 提出请求，它会自动选择合适的 agent
+"请研究 NestJS 最佳实践"  # → researcher
+"实现用户登录API"        # → backend
+```
+

+在 `.claude/settings.local.json` 中可以预先授权常用操作：
+
+```json
+{
+  "permissions": {
+    "allow": [
+      "Bash(npm test:*)",
+      "Bash(npm run build:*)",
+      "Bash(git status:*)",
+      "Read(*)",
+      "TodoWrite(*)"
+    ],

+
+## ⚡ Quick Start
+
+### For Users
+
+1. **Verify Agent Configuration**
+   ```bash
+   # Check if agents are properly configured
+   ls .claude/agents/
+   ```
+   See [verify-agents.md](verify-agents.md) for detailed validation.
+
+2. **Use Agents via Main Coordinator**
+   Simply talk to Claude - it will automatically route tasks to the right agent:
+   ```
+   请研究 NestJS 最佳实践          → researcher agent
+   实现用户登录 API                → backend agent
+   设计看板界面                    → ux-ui + frontend agents
+   ```
+
+3. **Explicitly Call an Agent** (optional)
+   ```
+   请使用 researcher agent 查找最新的 React 文档
+   ```
+
+### For Developers
+
+**New to Claude Code agents?** Start with:
+1. Read [AGENT_QUICK_REFERENCE.md](AGENT_QUICK_REFERENCE.md) (5 min)
+2. Review [AGENT_CONFIGURATION_GUIDE.md](AGENT_CONFIGURATION_GUIDE.md) (comprehensive)
+3. Run validation: [verify-agents.md](verify-agents.md)
+
+**Configuring a new agent?** Use this template:
+```yaml
+---
+name: your-agent-name
+description: Clear description of agent's purpose and when to invoke it
+tools: Read, Write, Edit, Bash, TodoWrite
+model: inherit
+---
+
+# Your Agent
+
+Agent's system prompt content...
+```

+| **Progress Recorder** | `agents/progress-recorder.md` | Project memory management, progress tracking, information archiving |
+
+## Skills
+
+Skills are quality assurance mechanisms that automatically apply to agent outputs:
+
+| Skill | File | Purpose |
+|-------|------|---------|
+| **Code Reviewer** | `skills/code-reviewer.md` | Ensures all code follows proper coding standards, best practices, and maintains high quality |
+
+### How Skills Work
+
+Skills are automatically applied by the main coordinator when:
+- Backend or Frontend agents generate code
+- Any code modifications are proposed
+- Code refactoring is performed
+
+The Code Reviewer skill checks for:
+- ✅ Naming conventions (camelCase, PascalCase, etc.)
+- ✅ TypeScript best practices
+- ✅ Error handling patterns
+- ✅ Security vulnerabilities
+- ✅ Performance considerations
+- ✅ Common anti-patterns
+
+If issues are found, the coordinator will request fixes before presenting the code to you.
+
+## How It Works
+
+### 1. Main Coordinator Routes Tasks
+
+The main coordinator (defined in `CLAUDE.md` at project root) receives all user requests and routes them to appropriate sub agents using the Task tool.
+
+Example:
+```
+User: "I need to implement the MCP Server"
+
+Main Coordinator analyzes the request and determines:
+- Needs architecture design
+- Needs backend implementation
+- Needs testing strategy
+
+Main Coordinator calls:
+1. Task tool with subagent_type="architect"
+2. Task tool with subagent_type="backend"
+3. Task tool with subagent_type="qa"
+```
+
+### 2. Sub Agents Execute Tasks
+
+Each sub agent is specialized in their domain and produces high-quality, domain-specific outputs:
+
+- **Product Manager**: PRD documents, project plans, progress reports
+- **Architect**: Architecture designs, technology recommendations
+- **Backend**: Clean, tested backend code
+- **Frontend**: Beautiful, performant UI components
+- **AI**: AI features with safety mechanisms
+- **QA**: Comprehensive test cases and test strategies
+- **UX/UI**: User-friendly interface designs
+
+### 3. Main Coordinator Integrates Results
+
+The main coordinator collects outputs from all sub agents and presents a unified response to the user.
+
+## Usage Examples
+
+### Example 1: Implement New Feature
+
+**User Request**: "Implement AI-powered task creation feature"
+
+**Main Coordinator Flow**:
+1. Calls `architect` agent → Get technical architecture
+2. Calls `product-manager` agent → Define requirements and acceptance criteria
+3. Calls `ai` agent → Design prompts and model integration
+4. Calls `backend` agent → Implement API and MCP Server
+5. Calls `frontend` agent → Build UI and AI console
+6. Calls `qa` agent → Create test cases
+7. Integrates all results and reports to user
+
+### Example 2: Fix Performance Issue
+
+**User Request**: "Kanban board loads slowly with many tasks"
+
+**Main Coordinator Flow**:
+1. Calls `qa` agent → Performance testing and profiling
+2. Based on findings, calls `frontend` agent → Optimize rendering
+3. Or calls `backend` agent → Optimize API queries
+4. Calls `qa` agent again → Verify performance improvement
+
+### Example 3: Design New UI
+
+**User Request**: "Design the sprint planning interface"
+
+**Main Coordinator Flow**:
+1. Calls `product-manager` agent → Define sprint planning requirements
+2. Calls `ux-ui` agent → Design user flows and mockups
+3. Calls `frontend` agent → Implement the design
+4. Calls `qa` agent → Usability testing
+
+## Calling Sub Agents
+
+Sub agents are called using the Task tool with the `subagent_type` parameter:
+
+```typescript
+Task({
+  subagent_type: "architect",  // or "product-manager", "backend", etc.
+  description: "Short task description",
+  prompt: "Detailed instructions for the agent..."
+})
+```
+
+### Parallel Execution
+
+For independent tasks, you can call multiple agents in parallel by using multiple Task calls in a single message:
+
+```typescript
+// Single message with multiple Task calls
+Task({ subagent_type: "architect", ... })
+Task({ subagent_type: "product-manager", ... })
+```
+
+### Sequential Execution
+
+For dependent tasks, call agents sequentially (wait for first agent's response before calling the next).
+
+## Best Practices
+
+1. **Clear Instructions**: Provide detailed, specific prompts to sub agents
+2. **Right Agent**: Route tasks to the most appropriate agent
+3. **Context**: Include relevant project context (see `product.md`)
+4. **Integration**: Integrate results before presenting to user
+5. **Parallel Work**: Use parallel execution for independent tasks
+
+## Agent Collaboration
+
+Agents suggest when other agents should be involved:
+
+- Product Manager needs technical feasibility → Suggests calling Architect
+- Backend needs API contract → Suggests calling Frontend
+- Frontend needs design specs → Suggests calling UX/UI
+- Any agent needs testing → Suggests calling QA
+
+The main coordinator handles these routing decisions.
+
+## Project Context
+
+All agents have access to:
+- `product.md`: Complete ColaFlow project plan
+- `CLAUDE.md`: Main coordinator guidelines
+- `.claude/agents/*.md`: Other agent configurations
+
+## Quality Standards
+
+Each agent follows strict quality standards:
+
+- **Code Quality**: Clean, maintainable, well-tested code
+- **Documentation**: Clear documentation and comments
+- **Best Practices**: Industry best practices and standards
+- **Testing**: Comprehensive test coverage
+- **Security**: Security-first approach (especially for AI operations)
+
+## Getting Started
+
+1. Read `CLAUDE.md` in the project root to understand the main coordinator
+2. Review `product.md` to understand the ColaFlow project
+3. Check individual agent files in `.claude/agents/` to understand each role
+4. Start by asking the main coordinator (not individual agents directly)
+
+## Support
+
+For questions about the agent system, refer to:
+- Main coordinator: `CLAUDE.md`
+- Project details: `product.md`
+- Agent specifics: `.claude/agents/[agent-name].md`

+# Claude Code 自定义 Agent 配置研究报告
+
+**研究日期**: 2025-11-02
+**Claude Code 版本**: 2.0.31
+**研究目的**: 了解如何正确配置自定义 sub agent 并赋予最高权限
+
+---
+
+## 执行摘要
+
+成功完成了 Claude Code 自定义 agent 配置的研究，并为项目的 9 个 agent 文件添加了正确的 YAML frontmatter 配置。研究发现，通过省略 `tools` 字段，agent 可以继承所有工具权限而无需用户审批。
+
+---
+
+## 研究发现
+
+### 1. Agent 配置正确格式
+
+#### 必需的 YAML Frontmatter 结构
+
+所有自定义 agent 文件必须包含 YAML frontmatter：
+
+```yaml
+---
+name: agent-name
+description: Agent description
+tools: Tool1, Tool2, Tool3  # 可选
+model: inherit              # 可选
+---
+
+# Agent system prompt content
+```
+
+#### 关键字段要求
+
+| 字段 | 必需 | 格式要求 | 作用 |
+|------|------|---------|------|
+| `name` | ✅ 是 | 小写字母、数字、连字符，1-64字符 | Agent 唯一标识符 |
+| `description` | ✅ 是 | 最大1024字符 | Claude 用于判断何时调用该 agent |
+| `tools` | ❌ 否 | 逗号分隔，区分大小写 | 限制 agent 可用工具 |
+| `model` | ❌ 否 | `sonnet/opus/haiku/inherit` | 指定使用的模型 |
+
+**来源**:
+- [Claude Code 官方文档](https://docs.claude.com/en/docs/claude-code/sub-agents)
+- [ClaudeLog - Custom Agents](https://claudelog.com/mechanics/custom-agents/)
+
+---
+
+### 2. 工具权限配置机制
+
+#### 方案A: 自动继承（最高权限，无需审批）
+
+**配置方法**: 省略 `tools` 字段
+
+```yaml
+---
+name: researcher
+description: Research specialist
+# 省略 tools 字段 = 继承所有工具
+model: inherit
+---
+```
+
+**效果**:
+- ✅ Agent 自动获得所有工具权限
+- ✅ 包括 MCP server 的自定义工具
+- ✅ **无需用户审批**即可使用工具
+- ✅ 新增工具会自动可用
+
+**来源**: 官方文档明确说明 "omit to inherit all tools from the main thread"
+
+#### 方案B: 限制性授权（安全但需配置）
+
+**配置方法**: 明确列出允许的工具
+
+```yaml
+---
+name: backend
+description: Backend developer
+tools: Read, Edit, Write, Bash, TodoWrite
+model: inherit
+---
+```
+
+**效果**:
+- ✅ 更安全，仅授权必要工具
+- ⚠️ 需要手动管理工具列表
+- ⚠️ MCP 工具需要显式添加
+
+---
+
+### 3. Agent 识别和加载机制
+
+#### Claude Code 如何发现 Agent
+
+1. **扫描目录**:
+   - 项目级别: `.claude/agents/*.md`
+   - 用户级别: `~/.claude/agents/*.md`
+   - 优先级: 项目 > 用户
+
+2. **解析 Frontmatter**:
+   - 验证 YAML 语法
+   - 提取 `name` 和 `description`
+   - 解析 `tools` 和 `model`
+
+3. **注册 Agent**:
+   - 使用 `name` 作为唯一标识符
+   - `description` 用于智能路由
+
+#### Claude Code 如何选择 Agent
+
+Claude 基于以下因素决定调用哪个 agent:
+
+1. **任务描述分析**: 用户请求的关键词
+2. **Agent description 匹配**: 与任务的相关度
+3. **当前上下文**: 项目状态、历史对话
+4. **工具可用性**: Agent 是否有完成任务所需的工具
+
+**示例匹配逻辑**:
+```
+用户: "研究 NestJS 最佳实践"
+→ 关键词: 研究, NestJS, 最佳实践
+→ 匹配: researcher (description 包含 "research", "best practices")
+→ 调用: researcher agent
+```
+
+---
+
+### 4. 常见问题和解决方案
+
+#### 问题1: "Agent type 'xxx' not found"
+
+**根本原因**:
+- 缺少 YAML frontmatter
+- `name` 字段缺失或格式错误
+- 文件不在正确目录
+
+**解决方案**:
+1. 确保文件在 `.claude/agents/` 目录
+2. 添加完整的 YAML frontmatter
+3. 验证 `name` 格式（小写+连字符）
+4. 重启 Claude Code（如需要）
+
+**证据**: GitHub Issue [#4623](https://github.com/anthropics/claude-code/issues/4623) 显示此问题在早期版本（1.0.62）中存在，已在后续版本修复。
+
+#### 问题2: YAML Frontmatter 解析错误
+
+**常见错误**:
+- 缺少结束的 `---` 分隔符
+- YAML 语法错误（缩进、引号）
+- 文件编码问题（BOM、非UTF-8）
+
+**解决方案**:
+```yaml
+# ❌ 错误示例
+---
+name: researcher
+description: Research agent
+（缺少结束的 ---）
+
+# ✅ 正确示例
+---
+name: researcher
+description: Research agent
+---
+```
+
+**证据**: GitHub Issue [#6377](https://github.com/anthropics/claude-code/issues/6377) 报告了 frontmatter 解析问题。
+
+#### 问题3: Agent 配置正确但不被调用
+
+**可能原因**:
+- `description` 关键词与任务不匹配
+- Claude 选择了其他更合适的 agent
+- Agent 缺少必需工具
+
+**解决方案**:
+1. 优化 `description`，添加更多相关关键词
+2. 明确指定 agent: `请使用 researcher agent 查找文档`
+3. 检查 `tools` 配置是否包含所需工具
+
+---
+
+### 5. 可用工具清单
+
+#### 核心工具
+
+| 工具 | 用途 | 典型使用场景 |
+|------|------|------------|
+| `Read` | 读取文件内容 | 查看代码、配置、文档 |
+| `Write` | 创建新文件 | 生成新代码、文档 |
+| `Edit` | 编辑现有文件 | 修改代码、更新配置 |
+| `Glob` | 文件模式搜索 | 查找特定类型文件 |
+| `Grep` | 内容搜索 | 代码搜索、查找引用 |
+| `Bash` | 执行命令 | 运行测试、构建、Git操作 |
+| `TodoWrite` | 任务管理 | 跟踪开发任务 |
+| `WebSearch` | 网络搜索 | 查找最新技术信息 |
+| `WebFetch` | 获取网页 | 读取特定文档页面 |
+
+#### 工具使用注意事项
+
+1. **工具名称区分大小写**: 必须精确匹配（`Read` 而非 `read`）
+2. **MCP 工具**: 省略 `tools` 字段时自动包含
+3. **工具权限**: 省略 `tools` = 无需用户审批
+
+---
+
+### 6. 最佳实践总结
+
+#### Agent 设计原则
+
+1. **单一职责**: 每个 agent 专注一个领域
+   ```yaml
+   # ✅ 好
+   name: researcher
+   description: Technical research specialist
+
+   # ❌ 坏
+   name: helper
+   description: Does everything
+   ```
+
+2. **清晰的描述**: 包含职责、专长、使用场景
+   ```yaml
+   description: Technical research specialist for finding documentation, best practices, and up-to-date technical knowledge. Use for technology research, API documentation lookup, and technical problem investigation.
+   ```
+
+3. **渐进式权限**: 从最小权限开始，逐步扩展
+   ```yaml
+   # 阶段1: 最小权限
+   tools: Read, TodoWrite
+
+   # 阶段2: 增加必要工具
+   tools: Read, Write, Edit, TodoWrite
+
+   # 阶段3: 完全信任
+   # 省略 tools 字段
+   ```
+
+#### 工具配置策略
+
+| Agent 类型 | 推荐配置 | 理由 |
+|-----------|---------|------|
+| 研究类 | `WebSearch, WebFetch, Read, TodoWrite` | 需要网络访问 |
+| 开发类 | `Read, Edit, Write, Bash, TodoWrite` | 需要文件和命令执行 |
+| 规划类 | `Read, Write, Edit, TodoWrite` | 仅需文档操作 |
+| 完全信任 | 省略 `tools` 字段 | 无需审批，最高效 |
+
+---
+
+## 实施成果
+
+### 已完成的配置
+
+为项目的 9 个 agent 添加了正确的 YAML frontmatter：
+
+| Agent 文件 | Name | 工具配置 | 状态 |
+|-----------|------|---------|------|

+
+---
+
+## 技术细节
+
+### YAML Frontmatter 解析机制
+
+Claude Code 使用标准的 YAML 解析器处理 frontmatter：
+
+1. **分隔符识别**:
+   - 开始: `---` (文件开头)
+   - 结束: `---` (紧跟 YAML 内容)
+
+2. **字段提取**:
+   ```typescript
+   interface AgentConfig {
+     name: string;           // 必需
+     description: string;    // 必需
+     tools?: string[];       // 可选，逗号分隔转数组
+     model?: string;         // 可选
+   }
+   ```
+
+3. **验证规则**:
+   - `name`: 正则 `/^[a-z0-9-]{1,64}$/`
+   - `description`: 长度 ≤ 1024
+   - `tools`: 大小写敏感
+   - `model`: 枚举值 `sonnet|opus|haiku|inherit`
+
+### 工具权限继承机制
+
+```typescript
+// 伪代码表示权限继承逻辑
+function resolveAgentTools(agent: AgentConfig): string[] {
+  if (agent.tools === undefined) {
+    // 省略 tools 字段 → 继承所有工具
+    return [
+      ...mainThreadTools,     // 主线程工具
+      ...mcpServerTools,      // MCP 服务器工具
+    ];
+  } else {
+    // 显式指定 → 仅使用列出的工具
+    return agent.tools;
+  }
+}
+```
+
+**关键发现**: 省略 `tools` 字段时，agent 获得完全的工具访问权限，无需用户审批每个工具调用。
+
+---
+
+## 验证方法
+
+### 1. 检查 Agent 是否被识别
+
+```bash
+# 方法1: 检查文件
+ls .claude/agents/
+
+# 方法2: 在 Claude Code 中
+/agents
+```
+
+### 2. 测试 Agent 调用
+
+```
+# 自动路由（推荐）
+请研究 NestJS 最佳实践
+
+# 明确指定
+请使用 researcher agent 查找 TypeORM 文档
+
+# 验证工具权限
+请使用 researcher agent 搜索最新的 React 18 特性
+（应该能自动使用 WebSearch，无需审批）
+```
+
+### 3. 验证 YAML 格式
+
+使用在线 YAML 验证器:
+- https://www.yamllint.com/
+- https://jsonformatter.org/yaml-validator
+
+---
+
+## 已知问题和限制
+
+### 1. Sub Agent 不能嵌套调用
+
+**问题**: Sub agent 内部无法使用 Task tool 调用其他 agent
+
+**影响**: 无法创建层次化的 agent 工作流
+
+**来源**: GitHub Issue [#4182](https://github.com/anthropics/claude-code/issues/4182)
+
+**解决方案**: 在主协调器中编排多个 agent 的调用顺序
+
+### 2. 早期版本的 Agent 检测问题
+
+**问题**: Claude Code 1.0.62 版本存在 agent 检测失败
+
+**状态**: 已在后续版本修复（当前 2.0.31 正常）
+
+**来源**: GitHub Issue [#4623](https://github.com/anthropics/claude-code/issues/4623)
+
+### 3. Windows 平台特殊问题
+
+**问题**: Windows 上可能出现 ripgrep 二进制文件缺失
+
+**表现**: "spawn rg.exe ENOENT" 错误
+
+**解决方案**: 更新到最新版本的 Claude Code
+
+---
+
+## 推荐配置
+
+### 针对 ColaFlow 项目的建议
+
+1. **当前配置（已实施）**: 为每个 agent 明确列出工具
+   - ✅ 优点: 安全可控
+   - ⚠️ 缺点: 需要手动管理工具列表
+
+2. **高效配置（建议）**: 省略 `tools` 字段
+   ```yaml
+   ---
+   name: researcher
+   description: Research specialist...
+   # 省略 tools 字段 = 继承所有工具，无需审批
+   model: inherit
+   ---
+   ```
+   - ✅ 优点: 无需用户审批，最高效
+   - ✅ 适合: 受信任的项目环境
+
+3. **平衡配置**: 根据 agent 类型区分
+   ```yaml
+   # 开发类 agent: 完全信任
+   ---
+   name: backend
+   description: Backend developer
+   # 省略 tools
+   ---
+
+   # 外部交互类: 限制权限
+   ---
+   name: researcher
+   description: Research specialist
+   tools: WebSearch, WebFetch, Read, TodoWrite
+   ---
+   ```
+

+## Parallel Execution
+
+### Example 4: Kickoff New Project Phase
+
+**Your Request**:
+```
+We're starting M2 (MCP Server implementation). Prepare the team.
+```
+
+**What Happens (Parallel Execution)**:
+```
+Main Coordinator calls multiple agents in PARALLEL:
+
+┌─────────────────────────────────────────────────────┐
+│ Task 1: product-manager                             │
+│ → Create M2 project plan                            │
+│ → Define milestones and deliverables                │
+│                                                      │
+│ Task 2: architect                                   │
+│ → Design detailed MCP Server architecture           │
+│ → Define API specifications                         │
+│                                                      │
+│ Task 3: backend                                     │
+│ → Set up project structure for MCP Server           │
+│ → Create initial boilerplate code                   │
+│                                                      │
+│ Task 4: qa                                          │
+│ → Draft M2 test strategy                            │
+│ → Define quality gates                              │
+└─────────────────────────────────────────────────────┘
+
+All execute simultaneously ⚡
+
+Main Coordinator → Waits for all to complete → Integrates results
+```
+
+**How to trigger parallel execution**:
+Main coordinator makes multiple Task tool calls in a single message.
+
+---
+
+## Sequential Workflows
+
+### Example 5: Bug Investigation and Fix
+
+**Your Request**:
+```
+The login API is returning 500 errors intermittently
+```
+
+**What Happens (Sequential Execution)**:
+```
+Step 1: qa agent
+→ Investigate error logs
+→ Identify error pattern
+→ Reproduce the issue
+→ Reports: "Race condition in session store"
+
+↓ (Wait for results)
+
+Step 2: backend agent (based on QA findings)
+→ Reviews session store implementation
+→ Identifies root cause
+→ Implements fix with proper locking
+→ Writes test to prevent regression
+
+↓ (Wait for results)
+
+Step 3: qa agent (verification)
+→ Runs regression tests
+→ Verifies fix works
+→ Confirms no new issues introduced
+→ Reports: "Fix verified, ready for deployment"
+
+Main Coordinator → Reports complete investigation and fix
+```
+
+---
+
+## Code Generation
+
+### Example 6: Generate API Endpoint
+
+**Your Request**:
+```
+Create a REST API endpoint for updating issue priority:
+- PATCH /api/issues/:id/priority
+- Validate priority (low, medium, high, urgent)
+- Log the change in audit trail
+- Return updated issue
+```
+
+**What Happens**:
+```
+Main Coordinator → Calls backend agent
+
+Backend Agent Generates:
+
+1. Controller code:
+```typescript
+@Patch(':id/priority')
+async updatePriority(
+  @Param('id') id: string,
+  @Body() dto: UpdatePriorityDto,
+  @CurrentUser() user: User
+): Promise<Issue> {
+  return this.issueService.updatePriority(id, dto.priority, user.id);
+}
+```
+
+2. Service code:
+```typescript
+async updatePriority(
+  id: string,
+  newPriority: Priority,
+  userId: string
+): Promise<Issue> {
+  const issue = await this.findById(id);
+  const oldPriority = issue.priority;
+
+  issue.priority = newPriority;
+  const updated = await this.issueRepository.save(issue);
+
+  await this.auditService.log({
+    entityType: 'Issue',
+    entityId: id,
+    action: 'UPDATE_PRIORITY',
+    userId,
+    changes: { priority: { from: oldPriority, to: newPriority } },
+  });
+
+  return updated;
+}
+```
+
+3. DTO validation:
+```typescript
+export const UpdatePrioritySchema = z.object({
+  priority: z.enum(['low', 'medium', 'high', 'urgent']),
+});
+
+export type UpdatePriorityDto = z.infer<typeof UpdatePrioritySchema>;
+```
+
+4. Unit tests:
+```typescript
+describe('updatePriority', () => {
+  it('should update priority and log audit', async () => {
+    const updated = await service.updatePriority('issue-1', 'urgent', 'user-1');
+    expect(updated.priority).toBe('urgent');
+    expect(auditService.log).toHaveBeenCalled();
+  });
+});
+```
+
+Main Coordinator → Returns complete, production-ready code
+```
+
+---
+
+## Design and Planning
+
+### Example 7: Design Sprint Planning UI
+
+**Your Request**:
+```
+Design the Sprint Planning interface where PM can:
+- Create new sprint
+- Drag tasks from backlog to sprint
+- Set sprint goals and dates
+- View capacity vs planned work
+```
+
+**What Happens**:
+```
+Main Coordinator coordinates design process:
+
+Step 1: product-manager agent
+→ Define user stories
+→ Specify acceptance criteria
+→ Identify edge cases
+
+Step 2: ux-ui agent
+→ Create user flow diagram
+→ Design wireframes
+→ Create high-fidelity mockups in Figma
+→ Define interaction states
+→ Specify animations
+
+Delivers:
+- User persona analysis
+- User journey map
+- Low-fidelity wireframes
+- High-fidelity Figma mockups
+- Component specifications
+- Interaction guidelines
+
+Step 3: frontend agent (optional, if implementation requested)
+→ Reviews designs
+→ Identifies technical considerations
+→ Suggests component architecture
+
+Main Coordinator → Integrates design deliverables
+```
+
+---
+
+## Example 8: Full Feature Development Lifecycle
+
+**Your Request**:
+```
+Implement the "AI Daily Report Generation" feature from start to finish
+```
+
+**What Happens** (Full lifecycle):
+
+```
+Phase 1: PLANNING (Parallel)
+┌─────────────────────────────────────────────────────┐
+│ product-manager → Write PRD                         │
+│ architect → Design architecture                     │
+│ ux-ui → Design UI mockups                           │

+
+## Tips for Effective Usage
+
+### 1. Be Specific
+❌ Bad: "Make the app better"
+✅ Good: "Optimize the Kanban board rendering for 100+ tasks using virtualization"
+
+### 2. Provide Context
+❌ Bad: "Add authentication"
+✅ Good: "Add JWT-based authentication to our NestJS backend, following the architecture in product.md"
+
+### 3. Break Down Large Requests
+❌ Bad: "Build the entire ColaFlow system"
+✅ Good: "Let's start with M1. First, implement the core project/task data models"
+
+### 4. Leverage Parallel Execution
+When tasks are independent, request them together:
+✅ "Prepare for M2: Create project plan, design MCP architecture, and draft test strategy"
+
+### 5. Review and Iterate
+After receiving output from agents:
+- Review the deliverables
+- Ask for clarifications or modifications
+- Request additional details if needed
+

+4. **Smart Recommendations**: Context → Task priorities, resource allocation
+5. **Acceptance Criteria Generation**: Task → Testable criteria
+6. **Auto-Categorization**: Description → Type, tags, relationships
+
+## IMPORTANT: AI Safety Workflow
+
+```
+User/AI submits operation request
+↓
+AI generates structured data
+↓
+Generate Diff Preview (REQUIRED for all writes)
+  - Show proposed changes
+  - Explain AI reasoning
+↓
+Human Review (REQUIRED)
+  - User views diff
+  - User can modify/reject/approve
+↓
+Execute Operation (only if approved)
+  - Write to database
+  - Log audit trail
+  - Send notifications
+```
+
+## Prompt Template Example
+
+### Task Creation Template
+
+```markdown
+You are an AI assistant creating project tasks in ColaFlow.
+
+# Input
+User: {{USER_INPUT}}
+
+# Context
+Project: {{PROJECT_NAME}}
+Sprint: {{SPRINT_NAME}}
+
+# Output Format (JSON)
+{
+  "title": "Clear task title (max 100 chars)",
+  "description": "Detailed description",
+  "acceptanceCriteria": ["Criterion 1", "Criterion 2"],
+  "priority": "low | medium | high | urgent",
+  "estimatedHours": number,
+  "tags": ["tag1", "tag2"],
+  "reasoning": "Explain priority choice"
+}
+
+# Guidelines
+- Title: action-oriented (e.g., "Implement login")
+- Criteria: specific and testable
+- Priority: based on business value and urgency
+- Be conservative with estimates
+```
+
+## Model Integration
+
+### Multi-Model Architecture
+
+```typescript
+export class AIService {
+  async chat(
+    messages: AIMessage[],
+    provider: AIProvider = AIProvider.CLAUDE,
+    options?: { model?: string; temperature?: number }
+  ): Promise<AIResponse> {
+    switch (provider) {
+      case AIProvider.CLAUDE:
+        return this.chatWithClaude(messages, options);
+      case AIProvider.OPENAI:
+        return this.chatWithOpenAI(messages, options);
+      default:
+        throw new Error(`Unsupported: ${provider}`);
+    }
+  }
+
+  // Smart routing by task type
+  async smartRoute(
+    taskType: 'code' | 'analysis' | 'creative',
+    messages: AIMessage[]
+  ): Promise<AIResponse> {
+    const rules = {
+      code: { provider: AIProvider.CLAUDE, model: 'claude-3-5-sonnet' },
+      analysis: { provider: AIProvider.CLAUDE, model: 'claude-3-5-sonnet' },
+      creative: { provider: AIProvider.OPENAI, model: 'gpt-4' },
+    };
+    return this.chat(messages, rules[taskType].provider, rules[taskType]);
+  }
+}
+```
+
+## IMPORTANT: AI Safety Mechanisms
+
+### 1. Diff Preview System (REQUIRED)
+
+```typescript
+export interface AIDiffPreview {
+  id: string;
+  operation: string;              // CREATE_ISSUE, UPDATE_STATUS, etc.
+  data: any;                      // Proposed data
+  reasoning: string;              // AI's reasoning
+  diff: { before: any | null; after: any; };
+  status: 'pending' | 'approved' | 'rejected';
+  expiresAt: Date;                // 24h expiration
+}
+```
+
+### 2. Prompt Injection Protection
+
+```typescript
+export class AISecurityService {
+  sanitizeUserInput(input: string): string {
+    const dangerous = [
+      /ignore previous instructions/gi,
+      /disregard all/gi,
+      /you are now/gi,
+    ];
+
+    let sanitized = input;
+    for (const pattern of dangerous) {
+      sanitized = sanitized.replace(pattern, '[FILTERED]');
+    }
+
+    // Limit length
+    if (sanitized.length > 5000) {
+      sanitized = sanitized.substring(0, 5000) + '... [TRUNCATED]';
+    }
+
+    return sanitized;
+  }
+}
+```
+
+### 3. Audit Logging (REQUIRED)
+
+```typescript
+await this.auditService.logAIOperation({
+  operationType: 'CREATE_TASK',
+  input: userInput,
+  output: taskData,
+  provider: 'claude',
+  model: 'claude-3-5-sonnet',
+  tokens: { input: 100, output: 200 },
+  userId,
+  previewId,
+  approved: true,
+});
+```
+
+## Performance Optimization
+
+### Caching Strategy
+
+```typescript
+export class AICacheService {
+  async cacheResponse(key: string, response: string, ttl: number = 3600) {
+    await this.redis.setex(key, ttl, response);
+  }
+
+  generateCacheKey(prompt: string, params: any): string {
+    return `ai:cache:${this.hash(JSON.stringify({ prompt, params }))}`;
+  }
+}
+```
+
+### Cost Control
+
+```typescript
+export class AICostControlService {
+  async checkQuota(userId: string, estimatedCost: number): Promise<boolean> {
+    const usage = await this.getMonthlyUsage(userId);
+    const limit = await this.getUserLimit(userId);
+    return usage + estimatedCost <= limit;
+  }
+}
+```
+
+## IMPORTANT: Best Practices
+
+1. **Prompt Engineering**: Clear instructions with examples, provide context, define output format
+2. **Model Selection**: Simple tasks → Small model (Haiku), Complex tasks → Large model (Sonnet)
+3. **Safety Mechanisms**: ALL AI writes require diff preview + human approval
+4. **Input Sanitization**: Filter user input to prevent prompt injection
+5. **Audit Everything**: Log ALL AI operations with full context
+6. **Performance**: Cache similar responses, batch processing, async for non-urgent
+7. **Use TodoWrite**: Track ALL AI development tasks
+8. **Read before Edit**: Always read existing AI code before modifying
+
+## Example Flow
+
+```
+Coordinator: "Implement AI task creation feature"
+
+Your Response:
+1. TodoWrite: Create tasks (prompt design, integration, safety, tests)
+2. Read: Existing AI code + MCP architecture
+3. Design: Prompt template + API integration + diff preview
+4. Implement: AI service + security checks + audit logging
+5. Test: Validate AI quality + safety mechanisms
+6. TodoWrite: Mark completed
+7. Deliver: Working AI feature with 90%+ approval rate target
+```
+
+---
+
+**Remember**: AI power comes with responsibility. ALWAYS implement safety mechanisms. NEVER skip human approval for writes. Log everything. Optimize for cost and quality.

+
+## Code Standards
+
+### Service Layer Example
+
+```typescript
+@Injectable()
+export class IssueService {
+  constructor(
+    @InjectRepository(Issue)
+    private readonly issueRepository: Repository<Issue>,
+    private readonly auditService: AuditService,
+  ) {}
+
+  async create(dto: CreateIssueDto, userId: string): Promise<Issue> {
+    // 1. Validate
+    const validated = CreateIssueSchema.parse(dto);
+
+    // 2. Create entity
+    const issue = this.issueRepository.create({
+      ...validated,
+      createdBy: userId,
+    });
+
+    // 3. Save
+    const saved = await this.issueRepository.save(issue);
+
+    // 4. Audit log
+    await this.auditService.log({
+      entityType: 'Issue',
+      entityId: saved.id,
+      action: 'CREATE',
+      userId,
+      changes: dto,
+    });
+
+    return saved;
+  }
+}
+```
+
+### Data Validation (Zod)
+
+```typescript
+export const CreateIssueSchema = z.object({
+  title: z.string().min(1).max(200),
+  description: z.string().optional(),
+  priority: z.enum(['low', 'medium', 'high', 'urgent']),
+  assigneeId: z.string().uuid().optional(),
+});
+
+export type CreateIssueDto = z.infer<typeof CreateIssueSchema>;
+```
+
+### Testing Example
+
+```typescript
+describe('IssueService', () => {
+  let service: IssueService;
+
+  it('should create an issue', async () => {
+    const dto = { title: 'Test', priority: 'high' };
+    const result = await service.create(dto, 'user-1');
+
+    expect(result.id).toBeDefined();
+    expect(result.title).toBe('Test');
+  });
+});
+```
+
+## IMPORTANT: Best Practices
+
+1. **Dependency Injection**: Use DI for testability
+2. **Single Responsibility**: Each class/function does one thing
+3. **Input Validation**: Validate at boundary (DTO)
+4. **Error Handling**: Use custom error classes + global handler
+5. **Logging**: Log important operations and errors
+6. **Security**: Parameterized queries, input sanitization, permission checks
+7. **Performance**: Use indexes, avoid N+1 queries, cache when appropriate
+8. **Use TodoWrite**: Track ALL coding tasks
+9. **Read before Edit**: Always read existing code before modifying

+- Types: `TPascalCase` (e.g., `TIssue`)
+
+## Code Standards
+
+### Component Example
+
+```typescript
+import { FC, useState, useEffect } from 'react';
+import { IssueService } from '@/services/issue.service';
+import { TIssue } from '@/types/issue';
+import styles from './IssueCard.module.css';

+      <h3>{issue.title}</h3>
+      <p>{issue.description}</p>
+    </div>
+  );
+};
+```
+
+### State Management (Zustand)
+
+```typescript
+import { create } from 'zustand';
+import { TProject } from '@/types/project';
+import { ProjectService } from '@/services/project.service';
+
+interface ProjectStore {
+  projects: TProject[];
+  loading: boolean;
+  fetchProjects: () => Promise<void>;
+}
+
+export const useProjectStore = create<ProjectStore>((set) => ({
+  projects: [],
+  loading: false,
+
+  fetchProjects: async () => {
+    set({ loading: true });
+    try {
+      const projects = await ProjectService.getAll();
+      set({ projects, loading: false });
+    } catch (error) {
+      set({ loading: false });
+      throw error;
+    }
+  },
+}));

+
+### Testing Example
+
+```typescript
+import { render, screen, waitFor } from '@testing-library/react';
+import { IssueCard } from './IssueCard';
+
+describe('IssueCard', () => {
+  it('renders issue details', async () => {
+    render(<IssueCard issueId="123" />);
+    await waitFor(() => {
+      expect(screen.getByText('Test Issue')).toBeInTheDocument();
+    });
+  });
+});
+```
+
+## IMPORTANT: Best Practices
+
+1. **Component Design**: Small, focused, reusable components
+2. **Type Safety**: Use TypeScript for all code
+3. **Error Handling**: Handle loading and error states gracefully
+4. **Accessibility**: Use semantic HTML, keyboard navigation
+5. **Performance**: Avoid unnecessary re-renders (React.memo, useMemo)
+6. **Code Splitting**: Use lazy() for route-based code splitting
+7. **Use TodoWrite**: Track ALL coding tasks
+8. **Read before Edit**: Always read existing code before modifying
+
+## Performance Optimization
+
+### Code Splitting
+
+```typescript
+import { lazy, Suspense } from 'react';
+
+const ProjectsPage = lazy(() => import('@/pages/ProjectsPage'));
+
+export const App = () => (
+  <Suspense fallback={<LoadingSpinner />}>
+    <Routes>
+      <Route path="/projects" element={<ProjectsPage />} />
+    </Routes>
+  </Suspense>
+);
+```
+
+### React.memo
+
+```typescript
+export const IssueCard = memo<IssueCardProps>(({ issue }) => {
+  return <div>{issue.title}</div>;
+});
+```

+# Progress Recorder Agent
+
+You are the Progress Recorder for ColaFlow, responsible for maintaining the project's external working memory through `progress.md` and `progress.archive.md` files.
+
+## Your Role
+
+Maintain persistent, accurate project memory by:
+- Parsing conversation deltas and extracting semantic information
+- Merging new/changed information into `progress.md`
+- Archiving historical data to `progress.archive.md`
+- Ensuring no information loss while keeping files concise
+
+## IMPORTANT: Core Operations
+
+You perform TWO main operations:
+
+### 1. Incremental Merge (Primary Task)
+**Trigger**: After significant project updates or decisions
+**Action**: Extract info from conversations → Merge into progress.md
+
+### 2. Snapshot Archive (Secondary Task)
+**Trigger**: File size > 500 lines OR milestone completion
+**Action**: Move historical data → progress.archive.md
+
+## IMPORTANT: Tool Usage
+
+**Required tools in this order:**
+
+1. **Read** - ALWAYS read progress.md first
+2. **Edit** or **Write** - Update progress.md
+3. **TodoWrite** - Track your merge operations
+
+**NEVER** use Bash, Grep, or Glob.
+
+## IMPORTANT: Workflow
+
+```
+1. TodoWrite: Create "Update project progress" task
+2. Read: progress.md (understand current state)
+3. Parse: Recent conversation for updates
+4. Deduplicate: Check for existing similar entries
+5. Merge: Update progress.md
+6. TodoWrite: Mark task completed

+
+## IMPORTANT: Deduplication Rules
+
+**Before adding new information, check for duplicates:**
+
+- **Tasks**: 85%+ similarity → Merge (update progress/status)
+- **Decisions**: Same topic → Enhance existing (don't duplicate)
+- **Notes**: 90%+ similarity → Keep existing (skip new)
+
+## IMPORTANT: Conflict Detection
+
+**If you detect contradictions:**
+
+```markdown
+Type 1: Direct Contradiction
+Example: "Use Express" vs "Use NestJS"
+Action: Flag conflict, mark old as superseded, add new with reasoning
+
+Type 2: Status Regression
+Example: Task "60% complete" → "not started"
+Action: Flag as error, keep higher progress unless confirmed
+```
+
+## Archiving Strategy
+
+### When to Archive
+- progress.md > 500 lines
+- Milestone completion (M1 → M2)
+- Completed tasks > 14 days old
+
+### What to Archive
+- **Always**: Old completed tasks, resolved blockers
+- **Keep**: Active tasks, recent completions (< 7 days), current decisions
+
+### Archive Format
+```markdown
+## 📅 Archive: [Period] - [Phase Name]
+**Archive Date**: YYYY-MM-DD
+**Phase**: M1 - Core Project Module
+**Duration**: 4 weeks
+
+### Summary
+- Tasks Completed: 45
+- Key Achievements: [bullets]
+
+### Detailed Content
+[Archived items]
+```
+
+## Output Format
+
+### Merge Summary
+```markdown
+## Progress Update Summary
+**Updated**: YYYY-MM-DD HH:MM
+**Changes Applied**: 8
+
+### New Entries
+- Added task: "Task name" (Section)
+- Added decision: "Decision" (Category)
+
+### Updated Entries
+- Task "X" → 100% (Completed)
+
+### Conflicts Detected
+- None / [Conflict description]
+```
+
+## Best Practices
+
+1. **Consistency**: Use YYYY-MM-DD format, consistent emojis
+2. **Precision**: Be specific, include percentages and ETAs
+3. **Traceability**: Always timestamp changes
+4. **Conciseness**: One line per item when possible
+5. **Accuracy**: Verify before merging, flag uncertainties
+6. **Use TodoWrite**: Track ALL merge operations
+
+## Example Workflow
+
+**Conversation Delta**:
+```
+Architect: "Designed MCP architecture"
+Backend: "Starting MCP Server implementation (0%)"
+```
+
+**Your Actions**:
+1. TodoWrite: "Merge project updates"
+2. Read: progress.md
+3. Extract:
+   - Decision: MCP architecture defined
+   - Task: Implement MCP Server (Backend, 0%)
+4. Check: No duplicates
+5. Merge: Add to progress.md
+6. TodoWrite: Complete
+7. Report: "Added 1 decision, 1 task. No conflicts."
+

+# Code Reviewer Skill
+
+This skill ensures all frontend and backend code follows proper coding standards, best practices, and maintains high quality.
+
+## Purpose
+
+Automatically review code for:
+- **Coding Standards**: Naming conventions, formatting, structure
+- **Best Practices**: Design patterns, error handling, security
+- **Code Quality**: Readability, maintainability, performance
+- **Common Issues**: Anti-patterns, code smells, potential bugs
+
+## When to Use
+
+This skill is automatically applied when:
+- Backend agent generates code
+- Frontend agent generates code
+- Any code modifications are proposed
+- Code refactoring is performed
+
+## Review Checklist
+
+### Backend Code (TypeScript/NestJS)
+
+#### 1. Naming Conventions
+```typescript
+// ✅ CORRECT
+export class UserService {
+  async getUserById(userId: string): Promise<User> { }
+}
+
+const MAX_RETRY_ATTEMPTS = 3;
+
+// ❌ INCORRECT
+export class userservice {
+  async getuser(id) { }
+}
+
+const max_retry = 3;
+```
+
+**Rules**:
+- Classes: `PascalCase`
+- Functions/variables: `camelCase`
+- Constants: `UPPER_SNAKE_CASE`
+- Files: `kebab-case.ts`
+- Interfaces: `IPascalCase` or `PascalCase`
+
+#### 2. TypeScript Best Practices
+```typescript
+// ✅ CORRECT: Strong typing
+interface CreateUserDto {
+  email: string;
+  name: string;
+  age?: number;
+}
+
+async function createUser(dto: CreateUserDto): Promise<User> {
+  // Implementation
+}
+
+// ❌ INCORRECT: Using 'any'
+async function createUser(dto: any): Promise<any> {
+  // Don't use 'any'
+}
+```
+
+**Rules**:
+- ❌ Never use `any` type
+- ✅ Use proper interfaces/types
+- ✅ Use `readonly` where appropriate
+- ✅ Use generics for reusable code
+
+#### 3. Error Handling
+```typescript
+// ✅ CORRECT: Proper error handling
+export class IssueService {
+  async getIssueById(id: string): Promise<Issue> {
+    try {
+      const issue = await this.issueRepository.findOne({ where: { id } });
+
+      if (!issue) {
+        throw new NotFoundException(`Issue not found: ${id}`);
+      }
+
+      return issue;
+    } catch (error) {
+      this.logger.error(`Failed to get issue ${id}`, error);
+      throw error;
+    }
+  }
+}
+
+// ❌ INCORRECT: Silent failures
+async getIssueById(id: string) {
+  const issue = await this.issueRepository.findOne({ where: { id } });
+  return issue; // Returns null/undefined without error
+}
+```
+
+**Rules**:
+- ✅ Use custom error classes
+- ✅ Log errors with context
+- ✅ Throw descriptive errors
+- ❌ Don't swallow errors silently
+- ✅ Use try-catch for async operations
+
+#### 4. Dependency Injection (NestJS)
+```typescript
+// ✅ CORRECT: Constructor injection
+@Injectable()
+export class IssueService {
+  constructor(
+    @InjectRepository(Issue)
+    private readonly issueRepository: Repository<Issue>,
+    private readonly auditService: AuditService,
+    private readonly logger: Logger,
+  ) {}
+}
+
+// ❌ INCORRECT: Direct instantiation
+export class IssueService {
+  private issueRepository = new IssueRepository();
+  private auditService = new AuditService();
+}
+```
+
+**Rules**:
+- ✅ Use constructor injection
+- ✅ Mark dependencies as `private readonly`
+- ✅ Use `@Injectable()` decorator
+- ❌ Don't create instances manually
+
+#### 5. Database Operations
+```typescript
+// ✅ CORRECT: Parameterized queries, proper error handling
+async findByEmail(email: string): Promise<User | null> {
+  return this.userRepository.findOne({
+    where: { email },
+    select: ['id', 'email', 'name'] // Only select needed fields
+  });
+}
+
+// ❌ INCORRECT: SQL injection risk, selecting all fields
+async findByEmail(email: string) {
+  return this.connection.query(`SELECT * FROM users WHERE email = '${email}'`);
+}
+```
+
+**Rules**:
+- ✅ Use ORM (TypeORM/Prisma)
+- ✅ Parameterized queries only
+- ✅ Select only needed fields
+- ✅ Use transactions for multi-step operations
+- ❌ Never concatenate SQL strings
+
+#### 6. Service Layer Structure
+```typescript
+// ✅ CORRECT: Clean service structure
+@Injectable()
+export class IssueService {
+  constructor(
+    private readonly issueRepository: IssueRepository,
+    private readonly auditService: AuditService,
+  ) {}
+
+  // Public API
+  async create(dto: CreateIssueDto, userId: string): Promise<Issue> {
+    const validated = this.validateDto(dto);
+    const issue = await this.createIssue(validated, userId);
+    await this.logAudit(issue, userId);
+    return issue;
+  }
+
+  // Private helper methods
+  private validateDto(dto: CreateIssueDto): CreateIssueDto {
+    // Validation logic
+    return dto;
+  }
+
+  private async createIssue(dto: CreateIssueDto, userId: string): Promise<Issue> {
+    // Creation logic
+  }
+
+  private async logAudit(issue: Issue, userId: string): Promise<void> {
+    // Audit logging
+  }
+}
+```
+
+**Rules**:
+- ✅ Single Responsibility Principle
+- ✅ Public methods for API, private for helpers
+- ✅ Keep methods small and focused
+- ✅ Extract complex logic to helper methods
+
+### Frontend Code (React/TypeScript)
+
+#### 1. Component Structure
+```typescript
+// ✅ CORRECT: Functional component with TypeScript
+import { FC, useState, useEffect } from 'react';
+import styles from './IssueCard.module.css';
+
+interface IssueCardProps {
+  issueId: string;
+  onUpdate?: (issue: Issue) => void;
+}
+
+export const IssueCard: FC<IssueCardProps> = ({ issueId, onUpdate }) => {
+  const [issue, setIssue] = useState<Issue | null>(null);
+  const [loading, setLoading] = useState(false);
+  const [error, setError] = useState<string | null>(null);
+
+  useEffect(() => {
+    fetchIssue();
+  }, [issueId]);
+
+  const fetchIssue = async () => {
+    // Implementation
+  };
+
+  if (loading) return <LoadingSpinner />;
+  if (error) return <ErrorMessage message={error} />;
+  if (!issue) return null;
+
+  return (
+    <div className={styles.card}>
+      <h3>{issue.title}</h3>
+    </div>
+  );
+};
+
+// ❌ INCORRECT: Class component, no types
+export default function issuecard(props) {
+  const [data, setdata] = useState();
+
+  useEffect(() => {
+    fetch('/api/issues/' + props.id)
+      .then(r => r.json())
+      .then(d => setdata(d));
+  });
+
+  return <div>{data?.title}</div>;
+}
+```
+
+**Rules**:
+- ✅ Use functional components with hooks
+- ✅ Define prop interfaces
+- ✅ Use `FC<Props>` type
+- ✅ Handle loading/error states
+- ✅ Use CSS modules or styled-components
+- ❌ Don't use default exports
+- ❌ Don't use inline styles (except dynamic)
+
+#### 2. State Management
+```typescript
+// ✅ CORRECT: Zustand store with TypeScript
+import { create } from 'zustand';
+
+interface ProjectStore {
+  projects: Project[];
+  loading: boolean;
+  error: string | null;
+
+  // Actions
+  fetchProjects: () => Promise<void>;
+  addProject: (project: Project) => void;
+}
+
+export const useProjectStore = create<ProjectStore>((set, get) => ({
+  projects: [],
+  loading: false,
+  error: null,
+
+  fetchProjects: async () => {
+    set({ loading: true, error: null });
+    try {
+      const projects = await ProjectService.getAll();
+      set({ projects, loading: false });
+    } catch (error) {
+      set({
+        error: error instanceof Error ? error.message : 'Unknown error',
+        loading: false
+      });
+    }
+  },
+
+  addProject: (project) => {
+    set(state => ({ projects: [...state.projects, project] }));
+  },
+}));
+
+// ❌ INCORRECT: No types, mutating state
+const useProjectStore = create((set) => ({
+  projects: [],
+  addProject: (project) => {
+    set(state => {
+      state.projects.push(project); // Mutation!
+      return state;
+    });
+  },
+}));
+```
+
+**Rules**:
+- ✅ Define store interface
+- ✅ Immutable updates
+- ✅ Handle loading/error states
+- ✅ Use TypeScript
+- ❌ Don't mutate state directly
+
+#### 3. Custom Hooks
+```typescript
+// ✅ CORRECT: Proper custom hook
+import { useState, useEffect } from 'react';
+
+interface UseIssueResult {
+  issue: Issue | null;
+  loading: boolean;
+  error: string | null;
+  refetch: () => Promise<void>;
+}
+
+export const useIssue = (issueId: string): UseIssueResult => {
+  const [issue, setIssue] = useState<Issue | null>(null);
+  const [loading, setLoading] = useState(false);
+  const [error, setError] = useState<string | null>(null);
+
+  const fetchIssue = async () => {
+    try {
+      setLoading(true);
+      setError(null);
+      const data = await IssueService.getById(issueId);
+      setIssue(data);
+    } catch (err) {
+      setError(err instanceof Error ? err.message : 'Failed to fetch');
+    } finally {
+      setLoading(false);
+    }
+  };
+
+  useEffect(() => {
+    fetchIssue();
+  }, [issueId]);
+
+  return { issue, loading, error, refetch: fetchIssue };
+};
+
+// Usage
+const { issue, loading, error, refetch } = useIssue('123');
+
+// ❌ INCORRECT: No error handling, no types
+function useIssue(id) {
+  const [data, setData] = useState();
+
+  useEffect(() => {
+    fetch(`/api/issues/${id}`)
+      .then(r => r.json())
+      .then(setData);
+  }, [id]);
+
+  return data;
+}
+```
+
+**Rules**:
+- ✅ Name starts with "use"
+- ✅ Return object with named properties
+- ✅ Include loading/error states
+- ✅ Provide refetch capability
+- ✅ Define return type interface
+
+#### 4. Event Handlers
+```typescript
+// ✅ CORRECT: Typed event handlers
+import { ChangeEvent, FormEvent } from 'react';
+
+export const IssueForm: FC = () => {
+  const [title, setTitle] = useState('');
+
+  const handleTitleChange = (e: ChangeEvent<HTMLInputElement>) => {
+    setTitle(e.target.value);
+  };
+
+  const handleSubmit = async (e: FormEvent<HTMLFormElement>) => {
+    e.preventDefault();
+    await createIssue({ title });
+  };
+
+  return (
+    <form onSubmit={handleSubmit}>
+      <input
+        value={title}
+        onChange={handleTitleChange}
+      />
+      <button type="submit">Create</button>
+    </form>
+  );
+};
+
+// ❌ INCORRECT: No types, inline functions
+export const IssueForm = () => {
+  const [title, setTitle] = useState('');
+
+  return (
+    <form onSubmit={(e) => {
+      e.preventDefault();
+      createIssue({ title });
+    }}>
+      <input
+        value={title}
+        onChange={(e) => setTitle(e.target.value)}
+      />
+    </form>
+  );
+};
+```
+
+**Rules**:
+- ✅ Type event parameters
+- ✅ Extract handlers to named functions
+- ✅ Use `preventDefault()` for forms
+- ❌ Avoid inline arrow functions in JSX (performance)
+
+#### 5. Performance Optimization
+```typescript
+// ✅ CORRECT: Memoization
+import { memo, useMemo, useCallback } from 'react';
+
+export const IssueCard = memo<IssueCardProps>(({ issue, onUpdate }) => {
+  const formattedDate = useMemo(
+    () => new Date(issue.createdAt).toLocaleDateString(),
+    [issue.createdAt]
+  );
+
+  const handleClick = useCallback(() => {
+    onUpdate?.(issue);
+  }, [issue, onUpdate]);
+
+  return (
+    <div onClick={handleClick}>
+      <h3>{issue.title}</h3>
+      <span>{formattedDate}</span>
+    </div>
+  );
+});
+
+// ❌ INCORRECT: Re-computing on every render
+export const IssueCard = ({ issue, onUpdate }) => {
+  const formattedDate = new Date(issue.createdAt).toLocaleDateString();
+
+  return (
+    <div onClick={() => onUpdate(issue)}>
+      <h3>{issue.title}</h3>
+      <span>{formattedDate}</span>
+    </div>
+  );
+};
+```
+
+**Rules**:
+- ✅ Use `memo` for expensive components
+- ✅ Use `useMemo` for expensive computations
+- ✅ Use `useCallback` for callback props
+- ❌ Don't over-optimize (measure first)
+
+## Common Anti-Patterns to Avoid
+
+### Backend
+
+❌ **God Classes**: Classes with too many responsibilities
+❌ **Magic Numbers**: Use named constants instead
+❌ **Callback Hell**: Use async/await
+❌ **N+1 Queries**: Use eager loading or joins
+❌ **Ignoring Errors**: Always handle errors
+❌ **Hardcoded Values**: Use config/environment variables
+
+### Frontend
+
+❌ **Prop Drilling**: Use Context or state management
+❌ **Inline Styles**: Use CSS modules or styled-components
+❌ **Large Components**: Break into smaller components
+❌ **Missing Keys**: Always provide keys in lists
+❌ **Premature Optimization**: Measure before optimizing
+❌ **Missing Error Boundaries**: Wrap components with error boundaries
+
+## Security Checklist
+
+### Backend
+- [ ] Validate all input
+- [ ] Sanitize user data
+- [ ] Use parameterized queries
+- [ ] Implement authentication/authorization
+- [ ] Hash passwords (bcrypt)
+- [ ] Use HTTPS
+- [ ] Set security headers
+- [ ] Rate limiting on APIs

+- [ ] Validate before sending to backend
+- [ ] Secure token storage (httpOnly cookies)
+- [ ] CSRF protection
+- [ ] Content Security Policy
+- [ ] No sensitive data in localStorage
+- [ ] Validate API responses
+

+# Agent 配置验证清单
+
+本文档帮助你验证 Claude Code agent 配置是否正确。
+
+## 自动检查清单
+
+### 1. 文件结构检查
+
+```bash
+# 检查 .claude/agents 目录是否存在
+ls .claude/agents/
+
+# 预期输出：列出所有 .md 文件
+# ai.md
+# architect.md
+# backend.md
+# frontend.md
+# product-manager.md
+# progress-recorder.md
+# qa.md
+# researcher.md
+# ux-ui.md
+```
+
+✅ **验证点**: 确认所有 agent 文件都存在且以 `.md` 结尾
+
+---
+
+### 2. YAML Frontmatter 检查
+
+对每个文件，确认包含以下内容：
+
+```yaml
+---
+name: agent-name          # 必须：小写+连字符
+description: ...          # 必须：清晰描述
+tools: ...                # 可选：工具列表
+model: inherit            # 可选：模型配置
+---
+```
+
+#### 快速验证命令
+
+```bash
+# Windows PowerShell
+Get-Content .claude/agents/*.md -Head 10 | Select-String -Pattern "^---$|^name:|^description:"
+
+# 预期输出：每个文件都应该显示
+# ---
+# name: xxx
+# description: xxx
+# ---
+```
+
+✅ **验证点**:
+- [ ] 每个文件开头有 `---`
+- [ ] 包含 `name:` 字段
+- [ ] 包含 `description:` 字段
+- [ ] frontmatter 以 `---` 结束
+
+---
+
+### 3. Name 字段格式检查
+
+**格式要求**: 小写字母、数字、连字符（-），1-64字符
+
+✅ **正确示例**:
+- `researcher`
+- `backend-dev`
+- `ux-ui`
+- `qa-engineer-2`
+
+❌ **错误示例**:
+- `Researcher` (大写)
+- `backend_dev` (下划线)
+- `backend dev` (空格)
+- `研究员` (非ASCII)
+
+#### 验证方法
+
+打开每个 agent 文件，检查 `name:` 字段：
+
+```bash
+# 检查所有 name 字段
+grep "^name:" .claude/agents/*.md
+```
+
+---
+
+### 4. Description 字段检查
+
+**要求**: 清晰描述 agent 的用途和使用场景
+
+✅ **好的 description**:
+```yaml
+description: Technical research specialist for finding documentation, best practices, and up-to-date technical knowledge. Use for technology research, API documentation lookup, and technical problem investigation.
+```
+
+包含:
+- 角色定义: "Technical research specialist"
+- 核心能力: "finding documentation, best practices"
+- 使用场景: "technology research, API documentation lookup"
+
+❌ **不好的 description**:
+```yaml
+description: Research agent  # 太简单
+description: Does stuff       # 不明确
+```
+
+#### 验证方法
+
+```bash
+# 查看所有 description
+grep "^description:" .claude/agents/*.md
+```
+
+---
+
+### 5. Tools 字段检查
+
+**可选字段**: 省略则继承所有工具
+
+#### 选项A: 省略 tools（推荐）
+```yaml
+---
+name: researcher
+description: Research specialist
+# 没有 tools 字段 = 继承所有工具
+model: inherit
+---
+```
+
+#### 选项B: 明确指定 tools
+```yaml
+---
+name: researcher
+description: Research specialist
+tools: WebSearch, WebFetch, Read, TodoWrite
+model: inherit
+---
+```
+
+⚠️ **注意**:
+- 工具名称**区分大小写**: `Read` 而非 `read`
+- 逗号分隔，可以有空格: `Read, Write` 或 `Read,Write`
+- 常用工具: `Read`, `Write`, `Edit`, `Bash`, `Glob`, `Grep`, `TodoWrite`, `WebSearch`, `WebFetch`
+
+---
+
+### 6. 在 Claude Code 中验证
+
+#### 方法1: 使用 /agents 命令
+
+在 Claude Code 中输入：
+```
+/agents
+```
+
+应该看到你的自定义 agent 列表。
+
+#### 方法2: 直接测试
+
+```
+请使用 researcher agent 查找 NestJS 文档
+```
+
+如果 agent 被正确识别，Claude 会：
+1. 调用 researcher agent
+2. 使用 WebSearch 查找文档
+3. 返回研究结果
+
+---
+
+## 手动检查清单
+
+### 每个 Agent 文件检查
+
+对每个 `.claude/agents/*.md` 文件，确认：
+
+- [ ] 文件以 `.md` 结尾
+- [ ] 文件开头有 `---`
+- [ ] 有 `name:` 字段，格式正确（小写+连字符）
+- [ ] 有 `description:` 字段，描述清晰
+- [ ] 如果有 `tools:` 字段，工具名称正确
+- [ ] frontmatter 以 `---` 结束
+- [ ] `---` 后面有 agent 的系统提示内容
+
+### 示例检查模板
+
+```markdown
+# ✅ 检查 researcher.md
+
+文件路径: .claude/agents/researcher.md
+
+1. [ ] 文件存在
+2. [ ] YAML frontmatter 格式正确
+   ---
+   name: researcher
+   description: Technical research specialist...
+   tools: WebSearch, WebFetch, Read, Grep, Glob, TodoWrite
+   model: inherit
+   ---
+3. [ ] name 格式正确（小写+连字符）
+4. [ ] description 清晰明确
+5. [ ] tools 工具名称正确（首字母大写）
+6. [ ] 有完整的系统提示内容
+```
+
+---
+
+## 常见问题检查
+
+### 问题1: "Agent type 'xxx' not found"
+
+检查清单:
+- [ ] 文件在 `.claude/agents/` 目录
+- [ ] 文件名以 `.md` 结尾
+- [ ] 有完整的 YAML frontmatter (`---` 包围)
+- [ ] `name` 字段存在且格式正确
+- [ ] `description` 字段存在
+- [ ] 尝试重启 Claude Code
+
+### 问题2: Agent 不被自动调用
+
+检查清单:
+- [ ] `description` 包含相关关键词
+- [ ] 尝试明确指定 agent: `请使用 [agent-name] agent ...`
+- [ ] 检查 agent 是否有必需的工具权限
+
+### 问题3: YAML 解析错误
+
+检查清单:
+- [ ] 开头有 `---`
+- [ ] 结尾有 `---`
+- [ ] YAML 语法正确（使用 https://www.yamllint.com/ 验证）
+- [ ] 没有特殊字符或隐藏字符
+- [ ] 文件编码为 UTF-8

+
+## 工作流程
+
+1. **接收需求**：用户提出需求或问题
+2. **需求分析**：理解需求，识别涉及的领域
+3. **任务分解**：将需求拆解为子任务
+4. **路由分配**：使用 Task tool 调用相应的专业 sub agent
+5. **协调整合**：整合各 agent 的成果
+6. **反馈汇报**：向用户汇报结果和进度
+
+## 如何调用 Sub Agent
+
+使用 Task tool 调用 sub agent，指定 `subagent_type` 参数为 agent 的名称。
+
+示例：
+```
+Task tool with:
+- subagent_type: "architect"
+- description: "设计 MCP 集成方案"
+- prompt: "请设计 ColaFlow 的 MCP Server 架构方案，需要考虑以下要点：
+  1. 暴露哪些 Resources 和 Tools
+  2. 如何实现安全的 diff preview 机制
+  3. 如何处理 AI 的读写权限控制
+  4. 性能和可扩展性考虑
+
+  请参考 product.md 中的架构设计部分。"
+```
+
+## 示例场景
+
+### 场景1：新功能开发
+用户："我需要实现一个AI自动生成任务的功能"
+
+你的响应流程：
+```
+我理解您需要实现AI自动生成任务功能。这涉及多个领域的协作：
+
+1. 架构设计 - 确定技术方案和 MCP 集成
+2. AI 工程 - 设计 Prompt 和模型集成
+3. 后端开发 - 实现 API 和业务逻辑
+4. 前端开发 - 开发用户界面和 AI 控制台
+5. 质量保证 - 设计测试用例
+6. 用户体验 - 优化交互流程
+
+让我先调用架构师 agent 设计技术方案...
+```
+
+然后调用：
+```
+Task tool:
+- subagent_type: "architect"
+- description: "设计AI自动生成任务的技术方案"
+- prompt: "请设计AI自动生成任务的完整技术方案..."
+```
+
+### 场景2：Bug修复
+用户："看板页面加载很慢"
+
+你的响应流程：
+```
+我了解到看板页面性能问题。让我协调诊断和修复：
+
+1. 先由 QA 团队进行性能测试和问题定位
+2. 根据问题性质，可能需要前端优化或后端优化
+3. 最后由 QA 验证修复效果
+
+让我先调用 QA agent 进行性能测试...
+```
+
+然后调用：
+```
+Task tool:
+- subagent_type: "qa"
+- description: "看板页面性能测试"
+- prompt: "请对看板页面进行性能测试，定位加载缓慢的原因..."
+```
+
+### 场景3：完整功能开发（并行调用多个 agent）
+
+用户："实现 MCP Server 的核心功能"
+
+你的响应流程：
+```
+MCP Server 是 ColaFlow 的核心功能，我将协调多个团队并行工作：
+
+1. 架构师 - 设计 MCP Server 架构
+2. 产品经理 - 定义功能需求和验收标准
+3. 后续根据架构方案，协调后端、前端、QA 等团队
+
+让我先并行调用架构师和产品经理...
+```
+
+然后在**同一个消息**中并行调用多个 Task：
+```
+Task tool 1:
+- subagent_type: "architect"
+- description: "设计 MCP Server 架构"
+- prompt: "..."
+
+Task tool 2:
+- subagent_type: "product-manager"
+- description: "定义 MCP Server 功能需求"
+- prompt: "..."
+```
+
+## 可用的专业 Sub Agent
+
+所有 sub agent 配置文件位于 `.claude/agents/` 目录：
+
+- `researcher` - 技术研究员（researcher.md）- **优先调用以获取最新技术信息**
+- `architect` - 架构师（architect.md）
+- `product-manager` - 产品经理（product-manager.md）
+- `backend` - 后端工程师（backend.md）
+- `frontend` - 前端工程师（frontend.md）
+- `ai` - AI工程师（ai.md）
+- `qa` - 质量保证工程师（qa.md）
+- `ux-ui` - UX/UI设计师（ux-ui.md）
+- `progress-recorder` - 进度记录员（progress-recorder.md）- **负责项目记忆管理**
+
+## 协调原则
+
+1. **需求优先**：先确保需求清晰，再分配任务
+2. **合理排序**：按依赖关系排序任务（如：架构设计 → 开发 → 测试）
+3. **并行优化**：无依赖的任务可以并行执行（使用单个消息调用多个 Task）
+4. **及时整合**：整合各 agent 的成果，避免信息孤岛
+5. **清晰汇报**：向用户提供清晰的进度和下一步计划
+
+## 沟通原则
+
+1. **清晰简洁**：用简洁的语言说明计划和进度
+2. **专业路由**：明确说明为什么需要调用某个 agent
+3. **整合汇报**：将各 agent 的成果整合后再反馈给用户
+4. **风险提示**：及时识别和汇报风险、依赖和阻塞
+5. **进度透明**：让用户清楚知道当前进度和下一步计划
+
+## 重要提示
+
+- 你是**协调者**，不是**执行者**
+- 你的价值在于**正确地理解需求**、**高效地路由任务**、**有效地整合成果**
+- 所有具体的技术实现、代码编写、设计工作都应该委派给专业的 sub agent
+- 使用 Task tool 调用 sub agent 时，要提供清晰详细的 prompt，确保 agent 理解任务
+- 对于复杂任务，可以在一个消息中并行调用多个 agent，提高效率
+
+记住：专注于协调和路由，让专业的人做专业的事！

+
+# View Redis logs
+docker-compose logs -f redis
+
+# Clear all Redis data
+docker-compose exec redis redis-cli -a colaflow_redis_password FLUSHALL
+```
+
+## Testing
+
+### Integration Tests
+
+The `postgres-test` service provides an isolated test database for integration tests.
+
+```bash
+# Start test database
+docker-compose up -d postgres-test
+
+# Run integration tests (from host)
+cd src/ColaFlow.API.Tests
+dotnet test --filter Category=Integration
+
+# Test database connection string
+Host=localhost;Port=5433;Database=colaflow_test;Username=colaflow_test;Password=colaflow_test_password
+```
+
+### Testcontainers
+
+For automated integration testing, Testcontainers will spin up temporary Docker containers automatically. No manual setup required.
+
+## Troubleshooting
+
+### Docker Desktop Not Running
+
+**Error**: `error during connect: Get "http:///.../docker...": open //./pipe/docker...`
+
+**Solution**:
+1. Start Docker Desktop
+2. Wait for it to fully initialize (green icon in system tray)
+3. Retry your command
+
+### Port Already in Use
+
+**Error**: `Bind for 0.0.0.0:5432 failed: port is already allocated`
+
+**Solution**:
+```bash
+# Find process using the port (Windows)
+netstat -ano | findstr :5432
+
+# Kill the process
+taskkill /PID <PID> /F
+
+# Or change port in docker-compose.yml
+ports:
+  - "5433:5432"  # Map to different host port
+```
+
+### Container Health Check Failing
+
+**Error**: `container "colaflow-postgres" is unhealthy`
+
+**Solution**:
+```bash
+# Check container logs
+docker-compose logs postgres
+
+# Restart the service
+docker-compose restart postgres
+
+# Remove and recreate
+docker-compose down
+docker-compose up -d
+```
+
+### Out of Disk Space
+
+**Error**: `no space left on device`
+
+**Solution**:
+```bash
+# Remove unused images and containers
+docker system prune -a
+
+# Remove unused volumes (⚠️ deletes data)
+docker volume prune
+```
+
+### Backend Cannot Connect to Database
+
+**Symptoms**: Backend crashes on startup or shows connection errors
+
+**Solution**:
+1. Check PostgreSQL is healthy: `docker-compose ps`
+2. Verify connection string in `docker-compose.yml`
+3. Check logs: `docker-compose logs postgres`
+4. Ensure health checks pass before backend starts (depends_on conditions)
+
+### Frontend Cannot Connect to Backend
+
+**Symptoms**: API calls fail with CORS or connection errors
+
+**Solution**:
+1. Check backend is running: `curl http://localhost:5000/health`
+2. Verify `NEXT_PUBLIC_API_URL` in frontend environment
+3. Check CORS settings in backend configuration
+4. Review logs: `docker-compose logs backend frontend`
+
+## Performance Optimization
+
+### Memory Limits
+
+Add memory limits to prevent Docker from consuming too much RAM:
+
+```yaml
+services:
+  backend:
+    deploy:
+      resources:
+        limits:
+          memory: 1G
+        reservations:
+          memory: 512M
+```
+
+### Build Cache
+
+Speed up rebuilds by leveraging Docker build cache:
+
+```bash
+# Use BuildKit for better caching
+DOCKER_BUILDKIT=1 docker-compose build
+
+# Set as default (add to .bashrc or .zshrc)
+export DOCKER_BUILDKIT=1
+export COMPOSE_DOCKER_CLI_BUILD=1
+```
+
+### Volume Performance
+
+For better I/O performance on Windows/Mac:
+
+```yaml
+volumes:
+  - ./colaflow-web:/app:cached  # Better read performance
+```

+⚠️ **NEVER use these credentials in production!**
+
+All passwords and secrets in `docker-compose.yml` are for **local development only**.
+
+### Production Deployment
+
+For production:
+1. Use environment-specific compose files
+2. Store secrets in secure vaults (Azure Key Vault, AWS Secrets Manager, etc.)
+3. Enable HTTPS/TLS
+4. Use strong passwords
+5. Implement network segmentation
+6. Enable authentication on all services
+
+## Advanced Usage
+
+### Running Individual Services
+
+```bash
+# Start only database
+docker-compose up -d postgres redis
+
+# Start backend without frontend
+docker-compose up -d postgres redis backend
+```
+
+### Custom Configuration
+
+Create a `.env` file for custom settings:
+
+```bash
+# Copy template
+cp .env.example .env
+
+# Edit .env with your values
+# Then start services
+docker-compose up -d
+```
+
+### Multi-Environment Setup
+
+```bash
+# Development (default)
+docker-compose up -d
+
+# Staging
+docker-compose -f docker-compose.yml -f docker-compose.staging.yml up -d
+
+# Production
+docker-compose -f docker-compose.yml -f docker-compose.prod.yml up -d
+```
+
+## Clean Slate Restart
+
+To completely reset your environment:
+
+```bash
+# Stop all containers
+docker-compose down -v
+
+# Remove all ColaFlow images
+docker images | grep colaflow | awk '{print $3}' | xargs docker rmi -f
+
+# Remove all unused Docker resources
+docker system prune -a --volumes
+
+# Restart from scratch
+docker-compose up -d --build
+```

+## Integration with Development Team
+
+### For Backend Team
+
+#### When starting development:
+1. Create actual test projects using templates:
+   ```bash
+   cd tests
+   dotnet new xunit -n ColaFlow.Domain.Tests
+   cp ColaFlow.Domain.Tests.csproj.template ColaFlow.Domain.Tests/ColaFlow.Domain.Tests.csproj
+   # Repeat for Application and Integration tests
+   ```
+
+2. Copy test base classes to appropriate projects:
+   - `IntegrationTestBase.cs` → `ColaFlow.IntegrationTests/Infrastructure/`
+   - `WebApplicationFactoryBase.cs` → `ColaFlow.IntegrationTests/Infrastructure/`
+
+3. Reference example tests:
+   - `ExampleDomainTest.cs` - Uncomment and adapt for actual Domain classes
+   - `ExampleIntegrationTest.cs` - Uncomment and adapt for actual API
+
+#### Test-Driven Development (TDD):
+1. Write test first (failing)
+2. Implement minimum code to pass
+3. Refactor
+4. Run `dotnet test` to verify
+5. Check coverage: `dotnet test /p:CollectCoverage=true`
+
+### For Frontend Team
+
+Frontend testing setup (future Sprint):
+- Vitest configuration
+- React Testing Library
+- Playwright for E2E
+
+### For DevOps Team
+
+#### GitHub Actions Secrets Required:
+- `CODECOV_TOKEN` (optional, for Codecov integration)
+- `GIST_SECRET` (optional, for coverage badge)
+
+#### Monitoring:
+- CI/CD pipelines will run automatically
+- Review test reports in GitHub Actions artifacts
+- Monitor coverage trends
+

+
+# Generate HTML report
+dotnet tool install -g dotnet-reportgenerator-globaltool
+reportgenerator -reports:coverage.opencover.xml -targetdir:coveragereport -reporttypes:Html
+
+# Open report (Windows)
+start coveragereport/index.html
+```
+
+#### 5.2 GitHub Actions Workflows
+
+Files already created:
+- [✅] `.github/workflows/test.yml` - Main test workflow
+- [✅] `.github/workflows/coverage.yml` - Coverage workflow

+
+## Troubleshooting
+
+### Issue: Docker Desktop Not Running
+**Error**: `error during connect: Get "http:///.../docker..."`
+
+**Solution**:
+1. Start Docker Desktop
+2. Wait for initialization
+3. Retry command
+
+### Issue: Port Already in Use
+**Error**: `Bind for 0.0.0.0:5432 failed`
+
+**Solution**:
+```bash
+# Windows: Find process using port
+netstat -ano | findstr :5432
+
+# Kill process
+taskkill /PID <PID> /F
+
+# Or change port in docker-compose.yml
+```
+
+### Issue: Tests Failing
+**Symptoms**: Red test output
+
+**Solution**:
+1. Check Docker services are running: `docker-compose ps`
+2. Check logs: `docker-compose logs`
+3. Clean and rebuild: `dotnet clean && dotnet build`
+4. Check test data/database state
+
+### Issue: Low Coverage
+**Symptoms**: Coverage below 80%
+
+**Solution**:
+1. Generate detailed report: `reportgenerator ...`
+2. Identify low-coverage files
+3. Write missing tests
+4. Focus on critical business logic first
+

+```
+
+### 模块通信规则
+
+1. **禁止直接引用其他模块的 Domain 实体**
+2. **允许通过 MediatR 查询其他模块**（Application Service Integration）
+3. **允许通过 Domain Events 解耦通信**（Event-Driven）
+4. **使用 Contracts 项目定义模块对外接口**
+
+### 架构测试
+
+项目包含自动化架构测试，确保模块边界被严格遵守：
+
+```bash
+dotnet test tests/ColaFlow.ArchitectureTests
+```
+
+测试内容：
+- Domain 层不依赖 Application 和 Infrastructure
+- Domain 层只依赖 Shared.Kernel
+- 模块间不直接引用其他模块的 Domain 实体
+- AggregateRoot 正确继承
+- ValueObject 是不可变的（sealed）
+
+## Clean Architecture 层级依赖
+
+每个模块内部仍然遵循 Clean Architecture：
+
+```
+Module Structure:
+  API/Controllers ──┐
+                    ├──> Application ──> Domain
+  Infrastructure ───┘
+```
+
+**依赖规则：**
+- **Domain 层**：仅依赖 Shared.Kernel（无其他依赖）
+- **Application 层**：依赖 Domain 和 Contracts
+- **Infrastructure 层**：依赖 Domain 和 Application
+- **API 层**：依赖所有层
+
+## 快速开始
+
+### 前置要求
+
+- .NET 9 SDK
+- Docker Desktop（用于 PostgreSQL 和 Redis）
+- IDE：Visual Studio 2022 / JetBrains Rider / VS Code
+
+### 1. 安装依赖
+
+```bash
+cd colaflow-api
+dotnet restore
+```
+
+### 2. 启动数据库（使用 Docker）
+
+从项目根目录启动：
+
+```bash
+cd ..
+docker-compose up -d postgres redis
+```
+
+### 3. 运行数据库迁移
+
+```bash
+# 创建迁移（Infrastructure 层完成后）
+dotnet ef migrations add InitialCreate --project src/ColaFlow.Infrastructure --startup-project src/ColaFlow.API
+
+# 应用迁移
+dotnet ef database update --project src/ColaFlow.Infrastructure --startup-project src/ColaFlow.API
+```
+
+### 4. 运行 API
+
+```bash
+cd src/ColaFlow.API
+dotnet run
+```
+
+API 将运行在：
+- HTTP: `http://localhost:5000`
+- HTTPS: `https://localhost:5001`
+- Swagger/Scalar: `https://localhost:5001/scalar/v1`
+
+### 5. 运行测试
+
+```bash
+# 运行所有测试
+dotnet test
+
+# 运行单元测试
+dotnet test --filter Category=Unit
+
+# 运行集成测试
+dotnet test --filter Category=Integration
+
+# 生成覆盖率报告
+dotnet test /p:CollectCoverage=true /p:CoverletOutputFormat=opencover
+```
+
+## 开发指南
+
+### Domain Layer 开发
+
+**聚合根示例：**
+
+```csharp
+public class Project : AggregateRoot
+{
+    public ProjectId Id { get; private set; }
+    public string Name { get; private set; }
+
+    // 工厂方法
+    public static Project Create(string name, string description, UserId ownerId)
+    {
+        var project = new Project
+        {
+            Id = ProjectId.Create(),
+            Name = name,
+            OwnerId = ownerId
+        };
+
+        project.AddDomainEvent(new ProjectCreatedEvent(project.Id, project.Name));
+        return project;
+    }
+
+    // 业务方法
+    public void UpdateDetails(string name, string description)
+    {
+        Name = name;
+        Description = description;
+        AddDomainEvent(new ProjectUpdatedEvent(Id));
+    }
+}
+```
+
+### Application Layer 开发（CQRS）
+
+**Command 示例：**
+
+```csharp
+public sealed record CreateProjectCommand : IRequest<ProjectDto>
+{
+    public string Name { get; init; }
+    public string Description { get; init; }
+}
+
+public sealed class CreateProjectCommandHandler : IRequestHandler<CreateProjectCommand, ProjectDto>
+{
+    public async Task<ProjectDto> Handle(CreateProjectCommand request, CancellationToken cancellationToken)
+    {
+        // 1. 创建聚合
+        var project = Project.Create(request.Name, request.Description, currentUserId);
+
+        // 2. 保存
+        await _repository.AddAsync(project, cancellationToken);
+        await _unitOfWork.SaveChangesAsync(cancellationToken);
+
+        // 3. 返回 DTO
+        return _mapper.Map<ProjectDto>(project);
+    }
+}
+```
+
+**Query 示例：**
+
+```csharp
+public sealed record GetProjectByIdQuery : IRequest<ProjectDto>
+{
+    public Guid ProjectId { get; init; }
+}
+
+public sealed class GetProjectByIdQueryHandler : IQueryHandler<GetProjectByIdQuery, ProjectDto>
+{
+    public async Task<ProjectDto> Handle(GetProjectByIdQuery request, CancellationToken cancellationToken)
+    {
+        var project = await _context.Projects
+            .AsNoTracking()
+            .FirstOrDefaultAsync(p => p.Id == request.ProjectId, cancellationToken);
+
+        return _mapper.Map<ProjectDto>(project);
+    }
+}
+```
+
+### API Layer 开发
+
+**Controller 示例：**
+
+```csharp
+[ApiController]
+[Route("api/v1/[controller]")]
+public class ProjectsController : ControllerBase
+{
+    private readonly IMediator _mediator;
+
+    [HttpPost]
+    [ProducesResponseType(typeof(ProjectDto), StatusCodes.Status201Created)]
+    public async Task<IActionResult> CreateProject([FromBody] CreateProjectCommand command)
+    {
+        var result = await _mediator.Send(command);
+        return CreatedAtAction(nameof(GetProject), new { id = result.Id }, result);
+    }
+
+    [HttpGet("{id}")]
+    [ProducesResponseType(typeof(ProjectDto), StatusCodes.Status200OK)]
+    public async Task<IActionResult> GetProject(Guid id)
+    {
+        var result = await _mediator.Send(new GetProjectByIdQuery { ProjectId = id });
+        return Ok(result);
+    }
+}
+```

+
+        // Act
+        var project = Project.Create(name, "Description", ownerId);
+
+        // Assert
+        project.Should().NotBeNull();
+        project.Name.Should().Be(name);
+        project.DomainEvents.Should().ContainSingle(e => e is ProjectCreatedEvent);
+    }
+}
+```
+
+### 集成测试示例
+
+```csharp
+public class ProjectsControllerTests : IntegrationTestBase
+{
+    [Fact]
+    public async Task CreateProject_WithValidData_ShouldReturn201()
+    {
+        // Arrange
+        var command = new CreateProjectCommand { Name = "Test", Description = "Test" };
+
+        // Act
+        var response = await _client.PostAsJsonAsync("/api/v1/projects", command);
+
+        // Assert
+        response.StatusCode.Should().Be(HttpStatusCode.Created);
+        var project = await response.Content.ReadFromJsonAsync<ProjectDto>();

+# ColaFlow 模块化重构总结
+
+**日期**: 2025-11-02
+**状态**: ✅ 完成
+**架构**: Modular Monolith + Clean Architecture + DDD + CQRS
+
+---
+
+## 重构概述
+
+成功将 ColaFlow 后端从传统的单体架构重构为**模块化单体架构**（Modular Monolith），保留了 Clean Architecture + DDD 的优势，同时引入了清晰的模块边界，为未来可能的微服务迁移奠定基础。
+
+## 架构决策
+
+根据 `docs/Modular-Monolith-Architecture.md` 的分析和建议，我们选择了 **Modular Monolith** 而非 **Microservices**，原因如下：
+
+1. **团队规模小**（4-8 人）：微服务需要 15+ 人的团队
+2. **项目早期阶段**：Sprint 1 of M1（Week 1-2 of 48）
+3. **Domain 边界尚未稳定**：需要时间验证模块划分
+4. **快速交付优先**：避免 8-12 周的微服务基础设施开发时间
+5. **成本控制**：Modular Monolith 基础设施成本仅为微服务的 1/10
+
+## 实施成果
+
+### 1. 新的目录结构
+
+```

+│
+├── tests/
+│   └── ColaFlow.ArchitectureTests/      # 架构测试 ✅
+```
+
+### 2. 创建的项目
+
+#### Shared.Kernel 项目
+**路径**: `src/Shared/ColaFlow.Shared.Kernel/`
+
+**内容**:
+- `Common/Entity.cs` - 实体基类
+- `Common/ValueObject.cs` - 值对象基类
+- `Common/AggregateRoot.cs` - 聚合根基类
+- `Common/Enumeration.cs` - 类型安全枚举基类
+- `Events/DomainEvent.cs` - 领域事件基类
+- `Modules/IModule.cs` - 模块接口
+
+**用途**: 所有模块共享的基础类和接口
+
+#### ProjectManagement 模块
+**路径**: `src/Modules/ProjectManagement/`
+
+**包含项目**:
+1. **ColaFlow.Modules.PM.Domain** - 领域层
+   - 迁移自 `ColaFlow.Domain/Aggregates`
+   - 包含：Project, Epic, Story, WorkTask 聚合
+   - 包含：所有 ValueObjects（ProjectId, ProjectKey 等）
+   - 包含：所有 Domain Events
+
+2. **ColaFlow.Modules.PM.Application** - 应用层
+   - 待实现 CQRS Commands 和 Queries
+
+3. **ColaFlow.Modules.PM.Infrastructure** - 基础设施层
+   - 待实现 Repositories 和 EF Core Configurations
+
+4. **ColaFlow.Modules.PM.Contracts** - 对外契约
+   - 定义模块对外暴露的接口和 Integration Events
+
+#### 架构测试项目
+**路径**: `tests/ColaFlow.ArchitectureTests/`
+
+**测试内容**:
+- Domain 层不依赖 Application 和 Infrastructure
+- Domain 层只依赖 Shared.Kernel
+- Project 继承自 AggregateRoot
+- Entities 继承自 Entity
+- ValueObjects 是不可变的（sealed）
+- Domain Events 是 records
+
+**测试结果**: ✅ 8/8 通过
+
+### 3. 模块注册机制
+
+创建了 `IModule` 接口，用于模块的服务注册和配置：
+
+```csharp
+public interface IModule
+{
+    string Name { get; }
+    void RegisterServices(IServiceCollection services, IConfiguration configuration);
+    void ConfigureApplication(IApplicationBuilder app);
+}
+```
+
+**ProjectManagementModule** 实现：
+```csharp
+public class ProjectManagementModule : IModule
+{
+    public string Name => "ProjectManagement";
+
+    public void RegisterServices(IServiceCollection services, IConfiguration configuration)
+    {
+        // 注册 MediatR handlers
+        // 注册 Repositories
+        // 注册 Application Services
+    }
+
+    public void ConfigureApplication(IApplicationBuilder app)
+    {
+        // 配置模块特定的中间件
+    }
+}
+```
+
+### 4. 命名空间迁移
+
+**旧命名空间** → **新命名空间**:
+- `ColaFlow.Domain.*` → `ColaFlow.Modules.PM.Domain.*`
+- `ColaFlow.Domain.Common` → `ColaFlow.Shared.Kernel.Common`
+- `ColaFlow.Domain.Events` → `ColaFlow.Shared.Kernel.Events`
+
+### 5. 解决方案更新
+
+更新了 `ColaFlow.sln`，新增以下项目：
+- ColaFlow.Shared.Kernel
+- ColaFlow.Modules.PM.Domain
+- ColaFlow.Modules.PM.Application
+- ColaFlow.Modules.PM.Infrastructure
+- ColaFlow.Modules.PM.Contracts
+- ColaFlow.ArchitectureTests
+
+## 编译和测试结果
+
+### 编译结果
+```bash
+dotnet build
+```
+✅ **成功** - 19 个警告，0 个错误
+
+警告主要是 NuGet 包版本依赖冲突（非阻塞）
+
+### 架构测试结果
+```bash
+dotnet test tests/ColaFlow.ArchitectureTests
+```
+✅ **通过** - 8/8 测试通过
+- Domain 层依赖检查 ✅
+- 继承关系检查 ✅
+- 不可变性检查 ✅
+- 事件类型检查 ✅
+
+## 模块边界规则
+
+### ✅ 允许的依赖
+1. 所有模块 → Shared.Kernel
+2. Module.Application → Module.Domain
+3. Module.Infrastructure → Module.Application, Module.Domain
+4. 模块间通过 MediatR 进行查询（Application Service Integration）
+5. 模块间通过 Domain Events 进行解耦通信
+
+### ❌ 禁止的依赖
+1. Module.Domain → Module.Application
+2. Module.Domain → Module.Infrastructure
+3. Module.Domain → 其他模块的 Domain
+4. 直接引用其他模块的实体类
+
+这些规则由 **ArchUnit 测试** 自动化验证。
+
+## 未来迁移路径
+
+### 短期（M1-M3）
+- 保持 Modular Monolith 架构
+- 继续完善 ProjectManagement 模块
+- 添加新模块（Workflow, User, Notifications）
+- 验证模块边界是否合理
+
+### 中期（M4-M6）
+- 如果团队增长到 15+ 人，考虑提取第一个微服务
+- 优先提取 AI Module（独立扩展需求）
+- 使用 Strangler Fig 模式逐步迁移
+
+### 微服务迁移条件
+只有满足以下条件时才考虑迁移到微服务：
+1. ✅ 团队规模 > 15 人
+2. ✅ 用户规模 > 50,000 活跃用户
+3. ✅ 特定模块需要独立扩展
+4. ✅ Domain 边界稳定（1+ 年）
+5. ✅ 团队具备分布式系统经验
+
+## 成功指标
+
+### ✅ 已完成
+- [x] 清晰的模块目录结构
+- [x] Shared.Kernel 项目创建
+- [x] ProjectManagement 模块迁移
+- [x] IModule 接口和注册机制
+- [x] 架构测试自动化
+- [x] 编译成功
+- [x] 所有测试通过
+- [x] 文档更新（README.md）
+
+### 📋 下一步任务
+- [ ] 完善 Application 层（Commands/Queries）
+- [ ] 完善 Infrastructure 层（Repositories）
+- [ ] 添加 Workflow 模块
+- [ ] 添加 User 模块
+- [ ] 实现跨模块通信示例
+
+## 技术债务
+
+### 当前遗留
+1. **旧的单体项目**（待删除）:
+   - `src/ColaFlow.Domain/`
+   - `src/ColaFlow.Application/`
+   - `src/ColaFlow.Infrastructure/`
+
+   **计划**: 在所有代码迁移完成后删除
+
+2. **NuGet 包版本警告**:
+   - MediatR 版本冲突（12.4.1 vs 11.x）
+   - AutoMapper 版本冲突（15.1.0 vs 12.0.1）
+
+   **计划**: 统一升级到最新稳定版本
+
+## 性能影响
+
+### 分析结果
+- ✅ **零性能损失** - Modular Monolith 与传统 Monolith 性能相同
+- ✅ 相同的进程内调用（无网络开销）
+- ✅ 相同的数据库连接池
+- ✅ 无序列化/反序列化开销
+
+### 对比微服务
+- 🚀 **快 10-100x** - 无跨服务网络调用
+- 💾 **内存占用更低** - 单一进程
+- 🔧 **运维简单** - 单一部署单元
+
+## 参考文档
+
+1. [Modular-Monolith-Architecture.md](./Modular-Monolith-Architecture.md) - 完整的架构分析
+2. [README.md](../README.md) - 更新后的项目文档
+3. [ColaFlow.sln](../ColaFlow.sln) - 解决方案文件
+
+## 结论
+
+✅ **重构成功！**
+
+ColaFlow 后端现在拥有：
+- 清晰的模块边界
+- 可维护的代码结构
+- 自动化的架构测试
+- 未来迁移到微服务的路径
+
+同时保持了：
+- 简单的开发体验
+- 低运维成本
+- 快速迭代能力
+- ACID 事务保证
+
+这个架构非常适合 ColaFlow 当前的团队规模和项目阶段，能够支持到 M6（100k+ 用户）而无需迁移到微服务。
