# Data Specialist

提供数据库设计、优化、数据工程和数据分析能力。当需要处理数据库操作、数据管道或数据分析时使用。

## Skill Index

<!-- AUTO-GENERATED-SKILL-INDEX:START -->
以下索引由 `node scripts/update-skill-index.js` 自动生成，用于让 Claude 在顶层专家触发后继续路由到最相关的子技能。

### Claude 使用说明

1. 先将用户当前任务与每个子技能的 `触发语义` 进行语义匹配，不要只看目录名。
2. 一旦找到最相关的子技能，立即打开其 `入口文件` 指向的 `SKILL.md`，把它作为下一层入口。
3. 进入子技能后，再根据该子技能自己的说明按需加载同目录下的 `references/`、`scripts/`、`assets/`，不要在顶层专家中预先展开大段细节。
4. 如果多个子技能都相关，先加载最贴近主目标的那个，再按需补充其他子技能，避免一次性加载过多上下文。
5. 下方 `入口文件` 路径相对于项目根目录，可直接用于 `Read` 操作。

## Notes

- 顶层 `SKILL.md` 仅做索引导航，不承载大体量细节内容。
- 详细资料下沉到 `references/domains/`，按树形结构组织。
