What it does

Crud Service is an agent skill from ArtisanCloud/PowerX. PowerX CRUD Service 规则(事务、审计、错误翻译、传输解耦)。

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs. The repository describes itself as: PowerX是一款以企业微信为基础的微信私域运营开放平台,帮助企业实现引流获客、精细运营。 The licence is Apache-2.0.

When your agent uses it

  • Backend & APIs work in your project

Example prompts

  • “/crud-service”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  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。

What it can do on your machine

Read from SKILL.md and the folder at commit 3f7619d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are yaml).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Crud Service loads about 1.6k tokens when it runs. Until then it costs about 13 tokens; SKILL.md has 18 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~13
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

PowerX CRUD Service

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)

service.yaml

kind: ruleset
name: crud_service
version: 1.0.0
owner: powerx
status: stable

meta:
  intent: >
    统一 Service 层职责:鉴权/审计、事务边界、幂等与并发控制、错误翻译(404/409),
    与 Repository/DTO/Handler/DI 对齐,保持传输无关(HTTP/gRPC 共用)。
  references:
    - crud_di.yaml
    - crud_repository.yaml
    - crud_dto.yaml
    - crud_api_rest.yaml
    - constitution.md

scope:
  applies_to:
    - "internal/service/**/**_service.go"

principles:
  - 传输无关:Service 只依赖 Repo 接口与 *shared.Deps,不依赖 gin/http/grpc。
  - 鉴权与审计:在 Service 层落实 RBAC/ABAC 与审计打点(入参需包含 actor/tenant/requestID)。
  - 事务:Service 负责确定事务边界;优先使用 Repo.WithTx 注入 tx。
  - 幂等与并发:Create 支持 Idempotency-Key(可选);Update 支持 If-Match/ETag(可选)。
  - 错误翻译:ErrRecordNotFound → 404;唯一键冲突/重复 → 409;其余 → 500(由上层桥接)。
  - 日志:必要路径要记录关键维度(tenant/actor/id)。
  - 形态约束:Service 默认以结构体 + `New*Service` 构造函数呈现;仅当满足“同一接口需要多种驱动/工厂模式”“为复用/测试提供可替换实现(如 handler、worker、远程代理共用服务)”等场景,或复用已有跨包 interface 规范时,才允许额外定义 interface 壳,并需在评审中说明理由。
  - Repo 生命周期:Service 构造时基于注入的 `*gorm.DB` 创建所需 Repository;禁止在 `shared.Deps` 或 Handler 层先行实例化 Repo 再传入 Service。

When should I use Crud Service?

Crud Service fits situations like: backend & APIs work in your project.

How do I install Crud Service in Claude Code?

Run `npx skills add ArtisanCloud/PowerX --skill crud-service -a claude-code`. Or copy the skill folder (.codex/skills/crud/service in ArtisanCloud/PowerX) into .claude/skills/crud-service in your project. Claude Code loads it when a task matches its description.

How do I install Crud Service in Codex?

Run `npx skills add ArtisanCloud/PowerX --skill crud-service -a codex`. Or copy the skill folder (.codex/skills/crud/service in ArtisanCloud/PowerX) into .agents/skills/crud-service in your project. Codex loads it when a task matches its description.

Can I use Crud Service in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ArtisanCloud/PowerX --skill crud-service -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/crud-service, .gemini/skills/crud-service, .github/skills/crud-service and .opencode/skills/crud-service in your project.

What does Crud Service need to run?

SKILL.md names no scripts, command-line tools or credentials: Crud Service is instructions for the agent only.

Does Crud Service access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Crud Service safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Crud Service use?

Crud Service is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Crud Service use?

About 1.6k tokens (SKILL.md is roughly 6.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Crud Service?

Skills that share tags, products or a category with Crud Service: Configuring Horizon (coollabsio/coolify, 63k stars), Nestjs Best Practices (rolling-scopes/rsschool-app, 10k stars), Sub2API Admin (Wei-Shaw/sub2api, 43k stars) and Firecrawl Build Onboarding (firecrawl/firecrawl, 190k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Crud Service?

ArtisanCloud (a GitHub organization) maintains it in ArtisanCloud/PowerX, which has 379 GitHub stars. The repository holds 21 skills in this directory. The repository was last updated on October 8, 2026.
