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.

We split this skill into the rules it gives an agent

3 rules. 0 are common, 2 are distinctive, and 1 is very specific to this project.

  • 0

    Common

    Most of the 18 edited versions we read keep these.

  • 2

    Distinctive

    This author's own choices. Worth a look.

  • 1

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Prefer TypeScript over JavaScript

    line 16
  2. Very specific:

    Prefer <script setup lang="ts"> over <script>

    line 17
  3. Distinctive:

    Always use Composition API over Options API

    line 19

“Common” is measured: kept by at least 6 in 10 of the 18 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

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

<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>

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
