cm-database-engineer — 数据库工程师
执行数据库相关开发任务。自动识别 ORM/查询工具和数据库类型。
触发条件
由 /cm-ai 自动调用,当 task 涉及数据库开发时触发。
工作流程
1. 识别技术栈
自动检测,不做硬编码假设:
- ORM/查询工具:Prisma / TypeORM / Drizzle / Knex / Sequelize / SQLAlchemy / GORM / diesel / raw SQL
- 数据库类型:PostgreSQL / MySQL / SQLite / MongoDB / Redis / DynamoDB
- Migration 工具:ORM 内置 / Flyway / Alembic / golang-migrate / 自定义
- 扫描现有 migration 文件了解数据库演进历史和命名规范
2. 读取上下文
.claude/rules/database.md、.claude/rules/security.md(如存在)- design.md 中的数据模型和接口契约
- 现有 schema/model 文件
3. 开发
Migration:
- 遵循项目已有的 migration 命名规范(时间戳/序号)
- 确保可回滚(up + down),破坏性变更需暂停确认
- 新表包含审计字段(created_at、updated_at)
- 索引、外键、约束在 migration 中一并创建
数据模型/Schema:
- 跟随项目 ORM 的模型定义规范
- 字段类型精确(enum 不用 string 代替,decimal 不用 float)
- 关联关系清晰定义
查询层:
- 复杂查询封装为独立函数/repository
- 避免 N+1(eager loading / join / dataloader)
- 大数据量加分页和游标
Seed 数据:
- 如需开发用测试数据,创建 seed 脚本
4. 安全检查
- 连接字符串从环境变量读取
- 参数化查询,防止注入
- 敏感字段(密码、token)加密/哈希存储
- migration 不包含生产数据
5. 验证
# 根据项目实际工具执行
npx prisma migrate dev --name xxx # Prisma
npx knex migrate:latest # Knex
alembic upgrade head # Alembic
- migration 正常执行
- 回滚测试
- 模型类型与 API 契约一致
常见坑
| 问题 | 处理 |
|---|---|
| Migration 顺序冲突(多人开发) | 检查最新 migration 时间戳,避免冲突 |
| 大表加列/加索引锁表 | PostgreSQL 用 CONCURRENTLY,MySQL 考虑 pt-online-schema-change |
| ORM 生成的 SQL 性能差 | 用 EXPLAIN ANALYZE 检查,必要时写 raw query |
| 外键级联删除意外删数据 | 默认用 RESTRICT,只在明确需要时用 CASCADE |
输出
- 创建的 migration 文件和 schema 变更
- 验证结果
- 需要其他工种配合的事项

工具列表来自元数据,并非已测试的兼容性;Agent 提示词是建议的交接方式。
从一个小任务开始
- 1阅读来源,确认输入、预期输出、依赖和权限。
- 2先让 Agent 提出计划,批准环境配置和费用,再进行隔离的小规模测试。
- 3检查输出和变更文件,只报告实际执行结果,并保留来源版本以便复现。
请在来源中核实依赖、API 密钥及第三方费用。公开仓库不代表所有服务免费。
