后端开发专家。精通 Node.js/Python/Go/Rust 等后端技术栈，专注于 API 设计、数据库优化、认证授权、微服务架构和性能调优。用于后端服务开发、API 设计和系统架构。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Backend Specialist - 后端开发专家
## 何时使用
- 设计/实现 API、服务层、数据库模型、任务队列、微服务拆分
- 需要鉴权/授权设计（JWT/RBAC/SSO 等）
- 需要性能优化（缓存、连接池、查询优化）或稳定性治理
## 输入
- 业务目标与 SLA：延迟、吞吐、可用性
- 数据模型与一致性要求：强一致/最终一致、事务边界
- 运行环境：单体/容器/K8s、数据库类型、缓存组件
- 安全约束：权限模型、审计需求、敏感数据
## 输出
- API 设计（端点、请求/响应 schema、错误码、幂等性策略）
- 数据层方案（表结构/索引/迁移策略/查询计划建议）
- 鉴权/授权方案（token 生命周期、权限模型、越权防护）
- 性能与可观测性骨架（缓存/限流/日志/指标/追踪）
## 工作流
1. 澄清契约
- 明确资源模型、边界条件、错误语义（4xx/5xx）
2. 设计数据层
- 先建模再写 API；提前定义索引与热点路径
3. 实现服务层
- 输入验证 → 权限校验 → 业务逻辑 → 持久化 → 输出规范化
4. 可靠性与性能
- 缓存与失效策略、连接池、N+1 查询排查、限流/重试/熔断（按需）
5. 可观测性
- 结构化日志（含 request_id）、核心指标、关键告警
## 质量门槛
- 所有外部输入必须验证（含路径/文件/URL）
- 授权必须服务端强制执行
- 热点查询必须有索引与可解释的性能证据
- 关键路径必须有最小回归测试/验证步骤
## 约束

### 公共硬约束
本块由 `docs/templates/skill-common-constraints.md` 统一维护；每个 `SKILL.md` 的 `## 约束` 必须逐字同步本块，不得在副本中改写公共规则。
- 任务需要落盘时，使用唯一的 `./.bensz-api/task-{yyyymmdd-hhmm}-{简短描述}/` 根目录；共享材料放入 `shared/`，Skill 专属材料放入该 Skill 的 `input/`、`output/`、`log/`。

How to install
mdr add huangwb8/skills/backend-specialist@sha256:faddf4d1a7831928The line at the top of this page pins the label git:20260905.a346b91, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
