vue-rules

vue-rules is a cursor rule for Cursor from beel-collab/presets.dev. It costs 0 tokens per session (1,132 once invoked), scanned A, original, MIT.

A set of file-based instructions for Cursor when working with Vue, a framework for building web interfaces, including server-rendered applications with Nuxt-like setups. It covers script setup, reusable composables, reactivity, server-side rendering, security, performance, and tests.

In plain words
What is it for?
Use it when creating or editing Vue components, composables, reactive state, server-rendered pages, or tests.
Why use it?
It keeps new code consistent with the project's Vue style and prevents mixing incompatible component patterns. It also helps preserve the distinction between browser code and server-rendered code.

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-rules 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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Vue Rules for Cursor: Script Setup, Composables and SSR

Install

Install the native export at .cursor/rules/vue-rules.mdc. Copy that export, not this catalog file. Catalog fields such as tools and author are for presets.dev. Install one skill file per name. Cursor, GitHub Copilot, Codex, Antigravity CLI, and Devin can all read .agents/skills, so a second copy with the same name collides.

Vue Rules for Cursor: Script Setup, Composables and SSR

File-scoped Cursor rule for Vue. It attaches when a matching file is in context.

Updated for Vue 3.5.45, Nov 2026

Do not upgrade dependencies or the framework version unless the task asks.

Project shape

New components use <script setup lang="ts"> when the project is on Vue 3 and TypeScript. Follow the existing single-file component layout. A composable is named useSomething and lives next to the feature that owns it.

Do not mix Options API and Composition API in a new component. An old Options component stays until you are asked to convert that file.

Reactivity

ref and reactive are the state. A computed derives a value. Do not copy a prop into a ref unless you need a local editable copy, and then say so.

Since Vue 3.5, destructuring defineProps() in <script setup> stays reactive. The compiler rewrites those bindings. Do not flag that. Destructuring a reactive() object, or a Pinia store without storeToRefs, still copies plain values and drops reactivity. On 3.4 and earlier, defineProps() destructure is also a plain copy unless the project turned the transform on.

A watcher has a cleanup. Stop a timer, an observer, and a request when the scope disposes. watchEffect is for a side effect you can rerun. It is not a place to derive state you could compute.

Props, emits, and templates

Declare props and emits with types. A prop is read-only. Emit the change and let the parent own the value. v-for uses a stable key, not the index, when the list can reorder.

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.
