backend-domain-architecture SKILL.md skillA

backend-domain-architecture from devcodex-labs/devcodex is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add devcodex-labs/devcodex/backend-domain-architecture@git:20260730.6ee304a

Pins git:20260730.6ee304a in mdr.lock. Pin the fingerprint instead.

后端领域架构专家 Owner — 当任务涉及领域模型、业务流程、权限、API、事务、一致性、幂等、兼容、数据边界、服务职责或用户要求从后端/领域专家角度审查时使用；要求用领域语言和业务不变量约束实现。.

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 Domain Architecture Skill

## 定位

本 Skill 负责后端领域架构 Owner 视角。它要求后端设计先表达领域语言、业务流程、不变量和一致性边界，再落到接口、服务、权限、事务、缓存和数据结构，避免把框架样板或测试 fixture 当领域设计。

## 触发条件

| 场景 | 是否触发 |
|------|:--------:|
| API、服务、权限、领域模型、业务流程、数据一致性或事务边界变化 | 必须 |
| 涉及幂等、并发、缓存、队列、长事务、兼容迁移、public types | 必须 |
| 用户指出示例像低阶、route 重复声明、权限/资源模型不专业 | 必须 |
| 纯静态文档或前端视觉调整，后端契约不变 | N/A + skipReason |

## 核心门禁

| Gate | 要求 | 证据 |
|------|------|------|
| `BackendDomainArchitectureGate` | 后端方案必须绑定领域语言、边界上下文、业务不变量和一致性策略 | 源码、类型、schema、测试、运行证据 |
| `DomainLanguageGate` | API、服务、文档和测试使用一致的领域词汇 | domainLanguage |
| `BoundedContextGate` | 区分服务职责、模块边界、共享库和历史 route namespace | boundedContext |
| `WorkflowInvariantGate` | 关键业务流程必须写前置条件、状态转换和不可破坏不变量 | workflowInvariants |
| `PermissionModelGate` | 权限、资源、action、route group 或 middleware 由推荐主路径承载 | permissionModel |
| `ConsistencyIdempotencyGate` | 事务、一致性、幂等、重试和兼容演进有明确策略 | transactionConsistency、idempotencyCompatibility |

## 执行步骤

1. 提取领域语言：实体、资源、动作、角色、状态、事件和约束。
2. 划定边界上下文：当前服务、共享库、adapter、legacy/compat、public API 和内部实现。
3. 描述业务流程：入口、前置条件、状态变化、失败分支、回滚和审计。
4. 设计权限模型：认证、授权、资源映射、route group、policy 和默认拒绝边界。
5. 设计一致性：事务范围、读写模型、缓存失效、幂等 key、重试和补偿。
6. 检查兼容性：public types、历史路由、迁移、版本化和消费者影响。

How to install

The exact contents, by fingerprint

mdr add devcodex-labs/devcodex/backend-domain-architecture@sha256:be1ffa5465862388

The line at the top of this page pins the label git:20260730.6ee304a, 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.
