Documentation Structure

文档结构

All documentation follows this hierarchy:

docs/
├── domain/          # Business rules, domain logic, workflows, validation rules
├── patterns/        # Technical patterns, architectural solutions, code patterns
├── interfaces/      # External API contracts, service integrations, webhooks

所有文档遵循以下层级结构：

docs/
├── domain/          # 业务规则、领域逻辑、工作流、验证规则
├── patterns/        # 技术模式、架构方案、代码模式
├── interfaces/      # 外部API契约、服务集成、Webhook

Workflow

工作流程

Step 0: DEDUPLICATION (REQUIRED - DO THIS FIRST)

步骤0：去重（必填 - 首先执行此步骤）

Always check for existing documentation before creating new files:

bash

undefined

创建新文档前务必检查现有文档：

bash

undefined

Search for existing documentation

搜索现有文档

grep -ri "main keyword" docs/domain/ docs/patterns/ docs/interfaces/ find docs -name "topic-keyword"


**Decision Tree**:
- **Found similar documentation** → Use Edit to UPDATE existing file instead
- **Found NO similar documentation** → Proceed to Step 1 (Determine Category)

**Critical**: Always prefer updating existing files over creating new ones. Deduplication prevents documentation fragmentation.

grep -ri "main keyword" docs/domain/ docs/patterns/ docs/interfaces/ find docs -name "topic-keyword"


**决策树**:
- **找到相似文档** → 编辑现有文件进行更新
- **未找到相似文档** → 进入步骤1（确定分类）

**关键提示**：优先更新现有文件而非创建新文件。去重可避免文档碎片化。

Step 1: Determine Category

步骤1：确定分类

Ask yourself:

Is this about business logic? →
```
docs/domain/
```
Is this about how we build? →
```
docs/patterns/
```
Is this about external services? →
```
docs/interfaces/
```

自问：

是否涉及业务逻辑？ →
```
docs/domain/
```
是否涉及开发实现方式？ →
```
docs/patterns/
```
是否涉及外部服务？ →
```
docs/interfaces/
```

Step 2: Choose: Create New or Update Existing

步骤2：选择：创建新文档或更新现有文档

Create new if:

No related documentation exists
Topic is distinct enough to warrant separation
Would create confusion to merge with existing doc

Update existing if:

Related documentation already exists
New info enhances existing document
Same category and closely related topic

创建新文档的情况：

无相关文档存在
主题足够独特，需要单独分离
合并到现有文档会造成混淆

更新现有文档的情况：

已有相关文档
新信息可补充现有文档
同一分类且主题密切相关

Step 3: Use Descriptive, Searchable Names

步骤3：使用具有描述性、可搜索的文件名

Good names:

```
authentication-flow.md
```
(clear, searchable)
```
database-migration-strategy.md
```
(specific)
```
stripe-payment-integration.md
```
(exact)

Bad names:

```
auth.md
```
(too vague)
```
db.md
```
(unclear)
```
api.md
```
(which API?)

好的文件名：

```
authentication-flow.md
```
（清晰、可搜索）
```
database-migration-strategy.md
```
（具体）
```
stripe-payment-integration.md
```
（精准）

不好的文件名：

```
auth.md
```
（过于模糊）
```
db.md
```
（不明确）
```
api.md
```
（指代哪个API？）

Step 4: Follow the Template Structure

步骤4：遵循模板结构

Use the templates in

templates/

for consistent formatting:

```
pattern-template.md
```
- For technical patterns
```
interface-template.md
```
- For external integrations
```
domain-template.md
```
- For business rules

使用

templates/

中的模板保证格式一致：

```
pattern-template.md
```
- 用于技术模式文档
```
interface-template.md
```
- 用于外部集成文档
```
domain-template.md
```
- 用于业务规则文档

Document Structure Standards

文档结构标准

Every document should include:

Title and Purpose - What this documents
Context - When/why this applies
Details - The actual content (patterns, rules, contracts)
Examples - Code snippets or scenarios
References - Related docs or external links

每份文档应包含：

标题与目的 - 本文档记录的内容
背景 - 适用场景与原因
详情 - 实际内容（模式、规则、契约）
示例 - 代码片段或场景
参考资料 - 相关文档或外部链接

Deduplication Protocol

去重协议

Before creating any documentation:

Search by topic:
```
grep -ri "topic" docs/
```
Check category: List files in target category
Read related files: Verify no overlap
Decide: Create new vs enhance existing
Cross-reference: Link between related docs

创建任何文档前：

按主题搜索：
```
grep -ri "topic" docs/
```
检查分类：列出目标分类下的文件
阅读相关文件：确认无重叠内容
决策：创建新文档或补充现有文档
交叉引用：在相关文档间建立链接

```

场景： 用户仅能编辑自己发布的内容

分析：

是否为业务规则？ → 是 →
```
docs/domain/
```
是否为外部服务？ → 否
检查现有文档：
```
find docs/domain -name "*permission*"
```

```
？ → 更新该文档
未找到？ → 创建
```
docs/domain/user-permissions.md
```

Output Format

输出格式

After documenting, always report:

📝 Documentation Created/Updated:
- docs/[category]/[filename].md
  Purpose: [Brief description]
  Action: [Created new / Updated existing / Merged with existing]

完成文档记录后，需提交以下报告：

📝 文档创建/更新：

Documentation Maintenance

文档维护

Beyond creating documentation, maintain its accuracy over time.

除创建文档外，还需长期维护文档的准确性。

Staleness Detection

过时检测

Check for stale documentation when modifying code:

Git-based staleness: Compare doc and code modification times
- If source file changed after related doc → flag for review
Reference validation: Verify documented items still exist
- Function names, API endpoints, configuration options
Example validation: Confirm code examples still work

修改代码时检查文档是否过时：

基于Git的过时检测：比较文档与代码的修改时间
- 如果源文件在相关文档之后修改 → 标记为需要审核
引用验证：验证文档中记录的内容是否仍存在
- 函数名、API端点、配置选项
示例验证：确认代码示例仍可正常运行

Staleness Categories

过时分类

Category	Indicator	Action
🔴 Critical	Code changed, doc not updated	Update immediately
🟡 Warning	> 90 days since doc update	Review needed
⚪ Info	> 180 days since update	Consider refresh

分类	指标	操作
🔴 关键	代码已修改，但文档未更新	立即更新
🟡 警告	文档超过90天未更新	需要审核
⚪ 信息	文档超过180天未更新	考虑刷新内容

Sync During Implementation

实施过程中的同步

When modifying code, proactively check documentation impact:

Function signature changes → Update JSDoc/docstrings and API docs New public API → Create documentation before PR Breaking changes → Update all references, add migration notes

修改代码时，主动检查对文档的影响：

函数签名变更 → 更新JSDoc/文档字符串及API文档 新增公开API → 提交PR前创建文档 破坏性变更 → 更新所有引用，添加迁移说明
