Supabase UI Skills

Supabase UI 设计指南

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

为使用AI Agent构建Supabase风格界面制定的约束规范。

When to Apply

适用场景

Reference these guidelines when:

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

在以下场景中参考本指南：

构建深色模式界面
创建受Supabase启发的设计系统
实现采用Inter字体和4px网格的UI

Colors

颜色规范

MUST use dark backgrounds (lightness < 20) for primary surfaces - detected lightness: 7
MUST use
```
#121212
```
as page background (
```
surface-base
```
)
SHOULD reduce color palette (currently 16 colors detected)
MUST maintain text contrast ratio of at least 4.5:1 for accessibility

主界面必须使用深色背景（亮度<20）——检测到的亮度为7
必须使用
```
#121212
```
作为页面背景（
```
surface-base
```
）
应精简调色板（当前检测到16种颜色）
为保证可访问性，文本对比度必须至少达到4.5:1
