PowerX: Skill for Codex

.codex/skills/crud/grpc/SKILL.md

crud-grpc is a skill for Codex from ArtisanCloud/PowerX. It costs 26 tokens per session (2,039 once invoked), scanned A, original, Apache-2.0.

A set of PowerX rules for building CRUD services over gRPC, a system for calling services through defined interface contracts. It covers protocol files, generated code, servers, interceptors, errors, pagination, and shared business logic.

In plain words
What is it for?
Use it when defining protobuf contracts, implementing gRPC servers and middleware, mapping errors, handling pagination, or checking generated-code and SDK layouts.
Why use it?
It keeps gRPC transport code aligned with the API contract and lets it reuse the same model, repository, and service layers as HTTP endpoints.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

crud-grpc scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

PowerX CRUD gRPC

步骤

  1. 打开 本文件内嵌规则。
  2. 按规则执行实现/校对。
  3. 完成后按核对清单验收。

核对点

  • 与 PowerX 当前代码结构、路径与命名一致。
  • 仅在传输层/契约层做职责内改动,不跨层越界。

规则(内嵌)

dev_crud_grpc_guides.md

# PowerX CRUD – gRPC Guides

> 本文与《dev_crud_http_guides.md》并列,复用同一套 **Model / Repository / Service** 主干,仅替换传输层为 gRPC。
> 入口仍由 `constitution.md` 控制,别名解析由同级 `manifest.yaml` 完成(`@dev-crud-grpc`)。

---

## 1. 适用范围(Scope)

* 与 HTTP 版 CRUD 规范**等价**:创建/查询/更新/删除、分页、错误、审计、多租户。
* 仅规定 **gRPC 传输层**:Server 行为、拦截器、错误映射、分页/上下文 DTO 对齐 **proto 契约**。
* 宪章入口仍为 `.specify/memory/constitution.md`(由其 `use: "` 决定是否引入本指南)。"

---

## 2. 目录与生成物(与你仓库对齐)

```
api/grpc/
  contracts/                # *.proto 契约(Buf 维护)
    buf.yaml
    buf.gen.yaml
    common/v1/{context,pagination,resource,response}.proto
    powerx/{iam,agent,auth/sts,plugin/control,setting}/v1/*.proto
  gen/go/...                # 代码生成产物(勿手改)
  sdk/{ts,rust,php}/...     # 多语言 SDK(封装拨号、上下文、重试等)

internal/transport/grpc/
  iam/{member_handler.go,team_handler.go,...}
  agent/{stream_handler.go,setting_handler.go,...}
  auth/{sts_handler.go}
  auth/middleware/auth_interceptor.go
```

* 你的 `api/grpc` 与 `internal/transport/grpc` 已经是成熟形态;本指南只统一**约束与验收**。

---

## 3. 设计原则(Transport-Agnostic)

* **服务端不写业务**:gRPC Server 仅做 **参数绑定/校验 → 调 Service → 错误映射**。
  示例:`MemberServer` 只解析上下文、分页、调用 `MemberService.ListMembers` 并映射返回。
* **多租户一致**:`tenant_id` 必须来自 **RequestContext 或 Metadata**;缺失返回 400 语义。
* **错误等价**:将应用错误(`ErrInvalidParam/ErrForbidden/ErrNotFound/ErrConflict`)映射为 gRPC `codes.*`;HTTP 与 gRPC 语义一致。
* **分页一致**:`common.v1.pagination.proto` 的 PageRequest/PageResponse 必须与 HTTP 页码/页大小语义一致。
* **审计与鉴权**:通过拦截器(Auth + Tenant)注入上下文,Service 侧照常记录审计;Server 不直接写审计逻辑。

---

## 4. Proto 契约(最小统一约束)

* **公共类型**:统一使用 `common/v1` 下的 `context.proto / pagination.proto / resource.proto / response.proto`。
* **包与版本**:采用 `powerx.<domain>.v1`,破坏性变更才升级 `v2`。
* **分页**:推荐结构(与你现有 common 保持一致):

    * `PageRequest{ page, page_size, sort_by, sort_order, offset? }`
    * `PageResponse{ total, page, page_size, pages? }`
* **Context**:`RequestContext{ tenant_id, request_id, actor_id, trace_id, ... }`,所有 RPC **强制**携带。
* 生成配置使用 Buf:`buf.yaml / buf.gen.yaml`(已存在)。

> 你现有 `powerx/iam/v1/member.proto`、`team.proto` 与 `common/v1/*.proto` 均满足上述形态,可直接沿用。

---

## 5. Server 实现(约束与示例)

### 5.1 绑定/校验

* **tenant 提取**:优先读 `RequestContext.tenant_id`,其次仅从 Metadata `tenant-id` 兜底(不接受任何 `x-powerx-*` 遗留租户头)。
  你的 `tenantIDFrom()` 已经实现这一落地逻辑。
* **分页映射**:`PageRequest(offset,page_size)` → `(page,size)` 的换算统一用工具函数(如 `pageFrom()`)。
* **错误回包**:Meta 中返回 `code/message/request_id`,与你的 `okMeta/badMeta` 一致(见 `member_handler.go`/`team_handler.go` 调用)。

### 5.2 调用 Service

* Server 仅调用同名用例,如 `MemberService.ListMembers/GetMember/...`;
* 严禁在 Server 内写 DB 或外部 IO 调用(与 HTTP 版一致)。

### 5.3 映射输出

* 领域对象 → PB:使用专用转换函数(如 `toPBMember()`),并保持 PRN/Ref 等字段预留。
* 分页总数写入 `PageResponse.total`,按需要计算 `pages`。

---

## 6. 拦截器(Auth / Tenant / Trace / Recovery)

* 统一在 `internal/transport/grpc/auth/middleware/auth_interceptor.go` 注册链:
  `Tracing → Auth/Tenant → Recovery → Logging/Audit(可选)`。
* Auth 成功后,将 `tenant_id`、`actor` 注入 `context.Context`,与 HTTP 中间件语义一致。
* Server 端实现保持**无状态**;租户与权限校验仍以 Service 为准。
  (你已存在 `auth_interceptor.go` 路径,保持即可。)

---

## 7. 错误映射(与 HTTP 等价)

| 应用错误                   | gRPC Code                                          |
| ---------------------- | -------------------------------------------------- |
| ErrInvalidParam / 参数缺失 | `codes.InvalidArgument`                            |
| ErrForbidden / 越权      | `codes.PermissionDenied`                           |
| ErrNotFound / 不存在      | `codes.NotFound`                                   |
| ErrConflict / 冲突       | `codes.AlreadyExists` 或 `codes.FailedPrecondition` |
| 其他未分类                  | `codes.Internal`                                   |

> 建议提供一个 `grpcerr.FromAppError(err)` 小工具集中处理映射;当前 `member_handler.go`/`team_handler.go` 以 “Meta + 200/400/500 语义”返回,你也可以逐步替换为标准 `status.Error` 形式以统一链路。

---

## 8. 流式(Server-Streaming)

* 与 SSE 事件顺序对齐:`start → data(token/partial) → final → end`;异常用 `error` 结束。
* 建议为长连接加入 heartbeat(超时时间与退避策略由客户端/SDK 控制)。
* 你的 `agent/stream_handler.go` 已是落地点,遵循以上语义即可。

---

## 9. 代码生成(Buf)

* 在 `api/grpc/contracts/` 下运行:

  ```
  buf lint
  buf breaking --against 'https://github.com/<org>/<repo>.git#branch=main'
  buf generate
  ```
* 生成物落在 `api/grpc/gen/go/**`,不要手改;SDK 封装在 `api/grpc/sdk/**`。

---

## 10. 验收要点(Checklist)

* [ ] **Server 零业务**:仅绑定/校验/调用 Service/错误映射(对齐 HTTP 版职能)。
* [ ] **多租户**:`tenant_id` 必带;缺失返回 400 语义或 `codes.InvalidArgument`。
* [ ] **分页一致**:PageRequest/PageResponse 与 HTTP 语义一致(`page/page_size/pages`)。
* [ ] **错误等价**:应用错误 → `codes.*`;或临时以 Meta 语义保持一致,逐步收敛至 `status.Error`。
* [ ] **拦截器链**:Tracing → Auth/Tenant → Recovery → Logging/Audit;服务端不重复做鉴权解析细节。
* [ ] **输出映射**:使用 `toPB*`,保留 `ResourceRef/PRN` 等字段空位。
* [ ] **生成流程**:`buf lint / breaking / generate` 通过;生成物与源码分离。
* [ ] **与 HTTP 等价**:同一用例在 HTTP 与 gRPC 的语义、错误、分页完全可对照。
