Claude Code Vue.js Skill: How to Build Smarter Vue Apps with AI Skills

What is a Claude Code skill?

A skill is a simple folder with a SKILL.md file. Inside that file you write two things:

  1. Frontmatter — a few lines at the top that tell Claude when to use the skill.
  2. Instructions — the steps Claude should follow when the skill runs. Claude Code reads these files and adds them to its toolkit. When your task matches a skill, Claude uses it automatically. You can also run a skill yourself by typing its name, like /build-vue-component.

Skills follow the Agent Skills open standard (agentskills.io). This means the same skill file works across many AI tools — not just Claude Code.

Why Vue developers should love skills

Vue projects are full of repeated work. You write components, composables, form validation, and tests over and over. Without skills, every new component means typing the same instructions to Claude again. With skills, your AI already knows:

  • Your Vue 3 style: <script setup>, Composition API, naming rules.
  • Your project conventions: no semicolons, single quotes, 100 character lines.
  • Your component structure and folder layout.
  • How you write and run tests. The result? Less typing, fewer mistakes, and code that looks like it was written by your own team.

Where skills live

Claude Code looks for skills in a few places:

LocationPathApplies toPersonal~/.claude/skills/<skill-name>/SKILL.mdAll your projectsProject.claude/skills/<skill-name>/SKILL.mdThis project onlyPlugin<plugin>/skills/<skill-name>/SKILL.mdWhere the plugin is enabled

For a team, put Vue skills in the project folder (.claude/skills/) and commit them to git. That way every developer — and every AI session — follows the same rules.

Claude Code watches skill folders for changes. Edit a SKILL.md and the new version works in your current session without a restart.

Create your first Vue skill

Let's build a simple skill that helps Claude create Vue 3 components the way you like them.

Step 1: Make a folder.

mkdir -p .claude/skills/vue-component

Step 2: Write the SKILL.md file.

---
description: Create Vue 3 components using the Composition API with script setup. Use when the user asks to build a new Vue component or page.
---

Create a Vue 3 component following these rules:

1. Use `<script setup>` and the Composition API. Never use the Options API.
2. Import composables and utilities from `@/composables/` and `@/utils/`.
3. Name the file with PascalCase, like `ContactForm.vue`.
4. Use `ref` and `computed` for state. Keep props simple with `defineProps`.
5. Add no semicolons and use single quotes for strings.
6. End the template with a clean, simple structure that matches the design system.

Step 3: Test it. Open Claude Code in your project and ask:

"Create a contact form component."

Claude reads the skill and builds the component exactly the way your team wants.

Frontmatter fields explained simply

You do not need to memorize every option. These are the ones you will use most:

FieldWhat it doesdescriptionTells Claude when to use the skill. Always add this.nameA display name. Claude Code uses the folder name for the command.disable-model-invocation: trueClaude never runs this skill by itself. Only you can type /name. Good for deploy or commit steps.user-invocable: falseOnly Claude can use it. Good for background knowledge.when_to_useExtra hints, like example questions that should trigger the skill.allowed-toolsTools Claude may use without asking, for example Bash(npm run test).

The description matters most. Write it like this: what the skill does, then when to use it. Claude reads it to decide if the skill fits your request.

Vue skill ideas you can copy

Here are practical Claude Code Vue.js skill ideas. Each one saves real time.

1. The Vue component builder

The example above. It keeps every component consistent with your design system and conventions.

2. The composable writer

---
description: Create reusable Vue composables with the Composition API. Use when the user wants shared logic like forms, API calls, or local storage.
---

Write a composable in `src/composables/`:

1. Export a function that returns `ref`, `computed`, and functions.
2. Keep the name meaningful, like `useContactForm`.
3. Handle loading, error, and success states clearly.
4. Add no semicolons and use single quotes.
5. Return only what the component needs to use.

3. The Vue tester

---
description: Write and run Vue tests with Vitest. Use when the user asks to test a component or composable.
---

1. Write tests in `src/components/__tests__/`.
2. Use `@vue/test-utils` to mount components.
3. Test user-visible behavior first: rendering, events, and forms.
4. Run `pnpm run test:unit` after writing the tests.

4. The refactor assistant

---
description: Migrate Vue 2 Options API code to Vue 3 Composition API. Use when the user asks to refactor or modernize old Vue components.
---

When refactoring a Vue component:

1. Convert `data`, `methods`, and `computed` into Composition API `ref`, functions, and `computed`.
2. Move lifecycle hooks (`mounted`, `beforeDestroy`) to `onMounted`, `onBeforeUnmount`.
3. Keep behavior identical — do not change what the component does.
4. Replace `this.$emit` and `this.$props` with `defineEmits` and `defineProps`.
5. Explain the changes briefly so the developer can review.

5. The project instructions skill

---
description: Apply this project's coding rules to every Vue file. Use for all Vue.js work in this repo.
---

This project uses Vue 3, Vite, and Tailwind CSS.

- Use the Composition API with `<script setup>`.
- Never use standard Tailwind color names for brand colors. Use `text-primary`, `bg-primary`.
- Keep components in `src/components/`, pages in `src/views/`.
- Add new translated strings to all three files: `english.js`, `french.js`, `arabic.js`.
- Run `pnpm run lint` before finishing.

This skill turns your project's rules into a file the whole team shares.

Bundled skills that help Vue work

Claude Code ships with ready-made skills. Some are very useful for Vue projects:

  • /run — launches your app and checks that a change works, not just that it compiles.
  • /verify — builds and runs your Vue app to confirm a change does what it should.
  • /code-review — reviews your latest code changes and catches problems before you commit.
  • /debug — helps you find and fix bugs faster.
  • /doctor — checks that your Claude Code setup is healthy. You can also use @vueuse/head, vue-router, and other Vue tools together with skills — the skill just adds the rules on top.

Skills vs CLAUDE.md

Many developers ask: why not just put everything in CLAUDE.md?

The short answer: context. CLAUDE.md loads on every session, which costs tokens and attention. A skill only loads when it is needed. Long reference material — like your full design system — belongs in a skill, not in CLAUDE.md. Keep CLAUDE.md for short, always-needed facts.

Claude Code remembers that skills follow the same idea: keep SKILL.md short and simple, and put the details in supporting files.

Best practices for Claude Code Vue.js skills

  1. Write a cleardescription. It decides when Claude uses the skill.
  2. Keep the skill short. Every line you add stays in context for the whole session.
  3. Use dynamic context. A line like git diff HEAD runs a command and pastes the result into the skill. Great for review skills.
  4. Commit skills to git. Your whole team gets the same AI behavior.
  5. Usedisable-model-invocationfor risky steps. Let only humans trigger deploys or commits.
  6. Split big skills into files. Reference extra docs and examples from SKILL.md instead of writing everything in one file.

    Start using your Vue.js skill today

Claude Code skills are one of the easiest ways to make AI coding feel personal. In ten minutes you can create a Vue skill that saves hours every week. Start with one simple skill — like the Vue component builder — and grow your set as you discover new repeat work.

The best skills are the ones your team actually uses. Put them in the project, commit them, and let Claude Code learn how you build Vue.
