Scope and alignment

This skill is aligned to the official Vant documentation entry points:

• Official website: https://vant-ui.github.io/
• Official guide: https://vant-ui.github.io/vant/#/zh-CN

The local skill content only claims coverage for files that actually exist in this skill directory. Do not reference non-existent local files. If the requested Vant component is not covered by a local example file, use the official guide as the primary reference and reuse the closest local pattern.

How to use this skill

Step 1: Identify the request area

Map the user request to one of these areas:

1. Quick start / setup

   • Installing Vant
   • Importing styles
   • Full import vs on-demand import
   • Vue 3 project bootstrap

2. Component implementation

   • Button
   • Cell
   • Form
   • Dialog
   • Toast
   • Popup

3. Global config and theming

   • ConfigProvider
   • theme-vars
   • Theme customization

4. API lookup

   • Common props
   • Component props/events/methods
   • Global config API

5. Template or scaffold

   • Project setup template
   • Reusable component structure

Step 2: Load only the matching files

Use the smallest relevant set of files.

A. Quick start / setup

• examples/getting-started/installation.md
• examples/getting-started/basic-usage.md
• templates/project-setup.md

Use these when the user asks how to install Vant, register components, import CSS, or start a Vue 3 + Vant project.

B. Covered component examples

Use only the component file that matches the user request:

• Button → examples/components/button.md
• Cell → examples/components/cell.md
• Form → examples/components/form.md
• Dialog → examples/components/dialog.md
• Popup → examples/components/popup.md
• Toast → examples/components/toast.md

C. Global config and theme

• api/config-provider.md
• examples/advanced/theme-customization.md

Use these for ConfigProvider, dark/light theme handling, theme-vars, CSS variables, or global UI behavior.

D. API lookup

• api/components.md
• api/config-provider.md

Use these when the user needs prop names, event names, method names, or a quick API summary.

E. Official navigation and coverage boundaries

• references/official-mapping.md

Use this file when:

• You need to confirm what this skill covers locally
• You need to route the user from an official Vant section to a local file
• You need to handle a Vant component that is not yet covered by a local example

Step 3: Follow the response workflow

When answering with this skill:

1. Confirm the target is Vant for Vue 3, not another Vue UI library.
2. Pick the matching local example or API file.
3. Keep code examples in Vue 3 Composition API style.
4. Preserve Vant naming and usage conventions:
   • import from vant
   • use van- components in templates
   • import vant/lib/index.css where setup requires it
5. Prefer mobile-first structure and touch-oriented interaction patterns.
6. If the requested component is not covered locally:
   • say that the local skill does not contain a dedicated example file for that component
   • route via references/official-mapping.md
   • use the official guide as the primary source of truth
   • adapt the closest covered local example style instead of inventing fake local files

Working rules

Do

• Use only local files that actually exist
• Keep answers anchored to the official Vant guide structure
• Prefer concrete component code over abstract explanation
• Use script setup style for Vue 3 examples unless the user already uses another style
• Mention ConfigProvider when the user asks about global theme or locale-like app-wide config
• Keep code samples runnable and focused

Do not

• Do not reference icon.md, tabs.md, navbar.md, or other files that do not exist in this skill
• Do not pretend this skill has full local coverage for every Vant component
• Do not mix Vant patterns with Element Plus, Ant Design Vue, or other UI libraries
• Do not output generic Vue UI advice when the user explicitly asks for Vant

Answer patterns

If the user asks for setup

Load:

• examples/getting-started/installation.md
• templates/project-setup.md

Return:

• install command
• CSS import
• registration strategy
• minimal Vue 3 + Vant starter

If the user asks for a covered component

Load:

• the matching file under examples/components/
• api/components.md if props/events are involved

Return:

• minimal example first
• then props/events/method notes
• then usage pitfalls if relevant

If the user asks for theme customization

Load:

• api/config-provider.md
• examples/advanced/theme-customization.md

Return:

• ConfigProvider usage
• theme-vars example
• CSS variable strategy
• scope and inheritance notes

If the user asks for an uncovered Vant component

Load:

• references/official-mapping.md
• nearest covered local file

Return:

• explicit note that the local skill has no dedicated example file for that component
• route to the official Vant guide section
• provide a Vant-consistent example following the same conventions used in this skill

Quality checklist

Before responding, verify that:

• the answer is specifically for Vant of Vue 3
• all referenced local files exist
• imports come from vant
• examples use Vue 3 syntax
• setup examples include CSS import where needed
• theme answers use ConfigProvider / theme-vars consistently
