Pitch UI Skills

Pitch UI 设计规范

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

用于借助AI Agent构建Pitch风格界面的约束性设计规范。

When to Apply

适用场景

Reference these guidelines when:

Building light-mode interfaces
Creating Pitch-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Pitch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
```
#000000
```
as page background (
```
surface-base
```
)
MUST use
```
#5836F6
```
for primary actions and focus states (
```
accent
```
)
SHOULD reduce color palette (currently 28 colors detected)
MUST maintain text contrast ratio of at least 4.5:1 for accessibility

应将浅色背景用于主要界面区域
必须使用
```
#000000
```
作为页面背景（
```
surface-base
```
）
必须使用
```
#5836F6
```
作为主要操作和焦点状态的颜色（
```
accent
```
）
应精简调色板（当前检测到28种颜色）
必须保持文本对比度至少为4.5:1以满足无障碍要求
