vue
Vue 3 Composition API, script setup macros, reactivity system, and built-in components. Use when writing Vue SFCs, defineProps/defineEmits/defineModel, watchers, or using Transition/Teleport/Suspense/KeepAlive.
Best use case
vue is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Vue 3 Composition API, script setup macros, reactivity system, and built-in components. Use when writing Vue SFCs, defineProps/defineEmits/defineModel, watchers, or using Transition/Teleport/Suspense/KeepAlive.
Teams using vue should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# Vue
> Based on Vue 3.5. Always use Composition API with `<script setup lang="ts">`.
## Preferences
- Prefer TypeScript over JavaScript
- Prefer `<script setup lang="ts">` over `<script>`
- For performance, prefer `shallowRef` over `ref` if deep reactivity is not needed
- Always use Composition API over Options API
- Discourage using Reactive Props Destructure

## Quick Reference
### Component Template
```vue
<script setup lang="ts">
import { ref, computed, watch, onMounted } from 'vue'
const props = defineProps<{
title: string
count?: number
}>()
const emit = defineEmits<{
update: [value: string]
}>()
const model = defineModel<string>()
const doubled = computed(() => (props.count ?? 0) * 2)
watch(() => props.title, (newVal) => {
console.log('Title changed:', newVal)
})
onMounted(() => {
console.log('Component mounted')
})
</script>
<template>
<div>{{ title }} - {{ doubled }}</div>
</template>
```
