Cal UI Skills

Cal UI 设计规范

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

为AI Agent构建Cal风格界面的约束规范。

When to Apply

适用场景

Reference these guidelines when:

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

在以下场景中参考本指南：

构建浅色模式界面时
创建受Cal启发的设计系统时
实现采用Inter字体和4px网格的UI时

Colors

色彩规范

SHOULD use light backgrounds for primary surfaces
MUST use
```
#FDFDFD
```
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

主界面区域应使用浅色背景
必须使用
```
#FDFDFD
```
作为页面背景（
```
surface-base
```
）
应精简色彩调色板（当前检测到16种颜色）
为保障无障碍性，文本对比度必须至少达到4.5:1
