vue3-pinia-composition

vue3-pinia-composition is a skill for Claude Code, Codex from 2428424081cn/Skill-mcp. It costs 36 tokens per session (480 once invoked), scanned A, original, MIT.

A set of Chinese-language rules for building Vue 3 applications with the Composition API and Pinia. Vue 3 is a JavaScript user-interface framework, while Pinia manages shared application state.

In plain words
What is it for?
Use it when designing or reviewing Vue 3 components, Pinia stores, composables, and reactive state handling.
Why use it?
It helps prevent a common bug where destructuring state removes Vue’s automatic updates. The rules also standardize composables, which are reusable pieces of Vue logic, and cleanup when components are removed.

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

vue3-pinia-composition 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 12d 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.

What it actually says

Vue 3 组合式 API 与 Pinia 架构规范

1. 响应式铁律 (Reactivity Rules)

  1. 优先使用 ref():对于基本类型和普通对象,优先统一使用 ref(),避免 reactive() 在解构赋值时丢失响应性。
  2. 禁止直接解构 Store:Pinia Store 状态必须使用 storeToRefs() 解构,Actions 可直接解构:
    const userStore = useUserStore();
    // ❌ 错误:会破坏响应性
    const { profile, isLoggedIn } = userStore;
    // ✅ 正确:保持响应性
    const { profile, isLoggedIn } = storeToRefs(userStore);
    const { login, logout } = userStore; // actions 保持引用
    
  3. 函数式 Setup Store:Pinia 推荐采用与 <script setup> 风格一致的函数式写法:
import { defineStore } from 'pinia';
import { ref, computed } from 'vue';

export const useUserStore = defineStore('user', () => {
  const token = ref<string | null>(null);
  const user = ref<UserProfile | null>(null);

  const isAuthenticated = computed(() => !!token.value);

  async function fetchCurrentUser() {
    if (!token.value) return;
    user.value = await api.getUser();
  }

  function clearSession() {
    token.value = null;
    user.value = null;
  }

  return { token, user, isAuthenticated, fetchCurrentUser, clearSession };
});

2. 组合式函数 (Composable) 规范

  • 命名统一以 use... 开头(如 usePagination.ts, useWebSocket.ts)。
  • 总是返回纯对象,包含响应式 Ref 与操作函数。
  • 必须处理组件卸载生命周期,在 onUnmounted() 中清理定时器与事件监听器。

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
