Liveblocks UI Skills

Liveblocks UI 设计规范

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

为使用AI Agent构建Liveblocks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 Liveblocks-inspired design systems
Implementing UIs with Inter font and 4px grid

以下场景请参考本指南：

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

Colors

颜色

MUST use dark backgrounds (lightness < 20) for primary surfaces - detected lightness: 0
MUST use
```
#000000
```
as page background (
```
surface-base
```
)
SHOULD reduce color palette (currently 11 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0
页面背景必须使用
```
#000000
```
（
```
surface-base
```
）
应精简调色板（当前检测到11种颜色）
为保证可访问性，文本对比度必须至少达到4.5:1
