vue-expert

vue-expert is a skill for Claude Code, Codex from eric861129/SKILLS_All-in-one. It costs 103 tokens per session (994 once invoked), scanned A, original, MIT.

A Vue 3 development assistant for building components and applications with the Composition API, Nuxt, Pinia, Quasar, and Vite. It also covers progressive web apps and mobile projects built with Capacitor.

In plain words
What is it for?
Use it to build Vue interfaces, reusable composables, Nuxt applications, Pinia stores, Quasar or Capacitor apps, and Vue component tests.
Why use it?
It helps organize Vue components, shared state, routing, and reactive code, while checking types and testing component behavior. This reduces common problems such as incorrect reactivity or unnecessary updates.

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

vue-expert 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 9d 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.

Vue Expert

Senior Vue specialist with deep expertise in Vue 3 Composition API, reactivity system, and modern Vue ecosystem.

Core Workflow

  1. Analyze requirements - Identify component hierarchy, state needs, routing
  2. Design architecture - Plan composables, stores, component structure
  3. Implement - Build components with Composition API and proper reactivity
  4. Validate - Run vue-tsc --noEmit for type errors; verify reactivity with Vue DevTools. If type errors are found: fix each issue and re-run vue-tsc --noEmit until the output is clean before proceeding
  5. Optimize - Minimize re-renders, optimize computed properties, lazy load
  6. Test - Write component tests with Vue Test Utils and Vitest. If tests fail: inspect failure output, identify whether the root cause is a component bug or an incorrect test assertion, fix accordingly, and re-run until all tests pass

Reference Guide

Topic Reference Load When
Composition API references/composition-api.md ref, reactive, computed, watch, lifecycle
Components references/components.md Props, emits, slots, provide/inject
State Management references/state-management.md Pinia stores, actions, getters
Nuxt 3 references/nuxt.md SSR, file-based routing, useFetch, Fastify, hydration

Quick Example

Minimal component demonstrating preferred patterns:

<script setup lang="ts">
import { ref, computed } from 'vue'

const props = defineProps<{ initialCount?: number }>()

const count = ref(props.initialCount ?? 0)
const doubled = computed(() => count.value * 2)

function increment() {
  count.value++
}
</script>

<template>
  <button @click="increment">Count: {{ count }} (doubled: {{ doubled }})</button>
</template>

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.
