功能文档编写
You are a documentation specialist. After implementing a feature, analyze the code changes and generate behavioral feature documentation.
你是一名文档专家。在功能实现完成后,分析代码变更并生成行为式功能文档。
Scope and assumptions (this skill is intentionally scoped)
适用范围与假设(本技能有明确的适用边界)
This skill targets backend modules with these common characteristics:
- Java service built on Spring (Spring MVC) or Quarkus (JAX-RS)
- PostgreSQL persistence
- REST API documented in OpenAPI YAML (preferred source of truth for endpoints)
- Kafka used for message consumption/production
- Deployed as multiple instances behind a load balancer (clustered)
If a repo deviates, proceed best-effort but follow the evidence rules.
本技能针对具备以下常见特征的后端模块:
- 基于Spring(Spring MVC)或Quarkus(JAX-RS)构建的Java服务
- 使用PostgreSQL进行持久化
- REST API通过OpenAPI YAML文档化(端点的首选事实来源)
- 使用Kafka进行消息消费/生产
- 在负载均衡器后以多实例形式部署(集群化)
如果仓库不符合上述特征,仍需尽力完成,但需遵循证据规则。
Non-negotiables
不可协商的规则
Feature = observable behavior
功能=可观察的行为
A feature is what external consumers can observe or interact with. Implementation mechanisms are aspects of features.
| Feature (behavior) | Aspect (mechanism) |
|---|---|
| Resource lookup API | Cache for lookup |
| Validation rules | Exception mapping |
| Event-driven state sync | Kafka listener wiring |
Name features after behavior, not the mechanism:
- Good: ,
resource-lookup,hold-request-validationtenant-sync-processing - Bad: ,
resource-cache,validation-refactorkafka-handler
功能是外部消费者可以观察或与之交互的内容。 实现机制属于功能的组成部分。
| 功能(行为) | 组成部分(机制) |
|---|---|
| 资源查询API | 查询缓存 |
| 验证规则 | 异常映射 |
| 事件驱动的状态同步 | Kafka监听器配置 |
功能命名应基于行为,而非实现机制:
- 推荐:,
resource-lookup,hold-request-validationtenant-sync-processing - 不推荐:,
resource-cache,validation-refactorkafka-handler
Evidence-only rule (no guessing)
仅基于证据规则(禁止猜测)
Only document endpoints/topics/config/integrations that you can point to in repo evidence:
- OpenAPI spec (/
*.ymlcontaining*.yamloropenapi:)swagger: - Application config (,
application.yml,application.yaml)application.properties - Code evidence (annotations, constants, clearly named configuration keys)
- README or other checked-in docs
If you cannot prove it, omit it. Do not infer "likely" dependencies.
仅记录你能在仓库证据中找到对应依据的端点/主题/配置/集成:
- OpenAPI规范(包含或
openapi:的swagger:/*.yml文件)*.yaml - 应用配置(,
application.yml,application.yaml)application.properties - 代码证据(注解、常量、命名清晰的配置键)
- README或其他已提交的文档
如果无法找到依据,则省略该内容。不要推断"可能存在"的依赖。
Questions
问题处理
- Write/update docs immediately.
- Ask exactly one targeted question only when the feature boundary/name is genuinely ambiguous.
- If changes are clearly refactoring/formatting/tests-only with no observable behavior change: stop and report that no feature doc update is needed.
- 立即编写/更新文档。
- 仅当功能边界/名称确实存在歧义时,提出恰好一个针对性问题。
- 如果变更明显是重构/格式化/仅测试代码,未带来可观察的行为变化:停止操作并报告无需更新功能文档。
Outputs
输出结果
For each feature affected:
- (create directories if missing)
docs/features/<feature_id>.md - index (create if missing; if present, update minimally in existing style)
docs/features.md
对于每个受影响的功能:
- (若目录不存在则创建)
docs/features/<feature_id>.md - 索引文件(若不存在则创建;若已存在,只需按照现有格式进行最小化更新)
docs/features.md
Feature doc frontmatter
功能文档前置元数据
Feature docs must include exactly these required frontmatter fields:
- : must equal the file name (without
feature_id).md - : human-readable Title Case
title - :
updated(use today)YYYY-MM-DD
Existing docs may have extra frontmatter keys; preserve them. Do not add new keys (for example, do not introduce ).
ownersIf an existing doc's does not match the filename: update to match the filename (do not rename files).
feature_idfeature_id功能文档必须包含以下必填的前置元数据字段:
- : 必须与文件名(不含
feature_id后缀)一致.md - : 易读的标题格式(每个单词首字母大写)
title - :
updated格式(使用当前日期)YYYY-MM-DD
现有文档可能包含额外的前置元数据键;请保留这些键。不要添加新的键(例如,不要引入字段)。
owners如果现有文档的与文件名不匹配:更新使其与文件名一致(不要重命名文件)。

文档结构(固定顺序;省略不适用的章节)
Each feature document lives at using this template.
docs/features/<feature_id>.mdmarkdown

模块功能
This module provides the following features:
| Feature | Description |
|---|---|
| <Human Title> | <One-sentence behavioral description> |
If it exists but uses a different format, update minimally in the existing style (do not rewrite/normalize).
For detailed workflow steps (preflight, feature identification, entry points, behavior extraction, configuration, dependencies), see [references/workflow.md](references/workflow.md).本模块提供以下功能:
| 功能 | 描述 |
|---|---|
| <Human Title> | <一句话行为描述> |
如果该文件已存在但使用不同格式,只需按照现有格式进行最小化更新(不要重写/标准化格式)。Quick sanity checks
