Vercel UI Skills

Vercel UI 设计指南

Opinionated constraints for building Vercel-style interfaces with AI agents.

用于借助AI Agent构建Vercel风格界面的专属约束规范。

When to Apply

适用场景

Reference these guidelines when:

Building light-mode interfaces
Creating Vercel-inspired design systems
Implementing UIs with Inter font and 4px grid

在以下场景中参考本指南：

构建浅色模式界面
创建受Vercel启发的设计系统
实现采用Inter字体与4px网格的UI

Colors

色彩规范

SHOULD use light backgrounds for primary surfaces
MUST use
```
#F9F9F9
```
as page background (
```
surface-base
```
)
MUST use
```
#000001
```
for primary actions and focus states (
```
accent
```
)
SHOULD reduce color palette (currently 12 colors detected)
MUST maintain text contrast ratio of at least 4.5:1 for accessibility

主界面应使用浅色背景
页面背景必须使用
```
#F9F9F9
```
（对应
```
surface-base
```
）
主要操作与焦点状态必须使用
```
#000001
```
（对应
```
accent
```
）
应精简调色板（当前检测到12种颜色）
为保障可访问性，文本对比度必须至少达到4.5:1

SHOULD use
```
size-*
```
for square elements instead of
```
w-*
```
+
```
h-*

应使用统一的元素宽度：8px, 181px, 66px
应保持以文本为主的布局，并具备清晰的层级结构
绝不能使用
```
h-screen
```
，需使用
```
h-dvh
