vue3-typescript

A set of practices for building Vue 3 interfaces with TypeScript and the Composition API, Vue's way to organize reusable component logic.

In plain words
What is it for?
Creating Vue components, composables, typed stores with Pinia, reactive state, and Vue projects using the script-setup style.
Why use it?
It helps keep component properties, events, reactive state, and shared logic type-checked and easier to maintain.

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-typescript 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 2d 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 TypeScript Skill

Build type-safe Vue 3 applications with Composition API.

When to Use

  • Creating Vue 3 components
  • Using Composition API
  • Setting up Vue with TypeScript
  • Managing Vue state

Critical Rules

Component Structure

  • Use <script setup> syntax
  • Define props with defineProps<Props>()
  • Use defineEmits<Emits>() for events
  • Leverage defineExpose when needed

TypeScript Integration

  • Enable strict mode in tsconfig.json
  • Use shallowRef for large objects
  • Type reactive objects properly
  • Use generic components with defineComponent

Composition API

  • Use composables for reusable logic
  • Prefix composables with 'use'
  • Return readonly objects when appropriate
  • Type provide/inject with InjectionKey

State Management

  • Use Pinia with TypeScript
  • Define stores with setup syntax
  • Type state, getters, and actions
  • Use storeToRefs for reactive destructuring

Examples

Good

<script setup lang="ts">
interface Props {
  title: string;
  count?: number;
}

const props = withDefaults(defineProps<Props>(), {
  count: 0
});

const emit = defineEmits<{
  update: [value: number];
}>();

const doubled = computed(() => props.count * 2);
</script>

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.

vue3-typescript is a skill published in the GitHub repository usrrname/cursorrules (10 stars, last pushed 4mo ago), licensed ISC. It adds 14 tokens to every session and 353 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
