Resend UI Skills

Resend UI 设计指南

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

为使用AI Agent构建Resend风格界面而制定的约束规范。

When to Apply

适用场景

Reference these guidelines when:

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

在以下场景下参考本指南：

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

Colors

颜色规范

MUST use dark backgrounds (lightness < 20) for primary surfaces - detected lightness: 2
MUST use
```
#060606
```
as page background (
```
surface-base
```
)
SHOULD limit color palette to 5 distinct colors
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2
必须使用
```
#060606
```
作为页面背景色（
```
surface-base
```
）
应将调色板限制为5种不同颜色
为保证可访问性，文本对比度必须至少达到4.5:1
