Lattice UI Skills

Lattice UI设计规范

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

为使用AI Agent构建Lattice风格界面而制定的约束规范。

When to Apply

适用场景

Reference these guidelines when:

Building light-mode interfaces
Creating Lattice-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Lattice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

SHOULD use light backgrounds for primary surfaces
MUST use
```
#FEFDFC
```
as page background (
```
surface-base
```
)
MUST use
```
#26B177
```
for primary actions and focus states (
```
accent
```
)
SHOULD reduce color palette (currently 37 colors detected)
MUST maintain text contrast ratio of at least 4.5:1 for accessibility

主界面应使用浅色背景
页面背景必须使用
```
#FEFDFC
```
（
```
surface-base
```
）
主要操作和焦点状态必须使用
```
#26B177
```
（
```
accent
```
）
应精简调色板（目前检测到37种颜色）
为了可访问性，文本对比度必须至少达到4.5:1

SHOULD use structural skeletons for loading states
MUST show errors next to where the action happens
NEVER block paste in
```
input
```
or
```

Animation

动画

NEVER add animation unless it is explicitly requested
MUST animate only compositor props (

top
```
,
```
left
```
,
```
margin
```
,
```
padding
```
)
SHOULD use
```
ease-out
```
on entrance animations
NEVER exceed
```
200ms
```
for interaction feedback
SHOULD respect
```
prefers-reduced-motion
```

除非明确要求，否则绝不要添加动画
仅能对合成器属性（

NEVER animate large
```
blur()
```

```
will-change
```
outside an active animation
NEVER use

for anything that can be expressed as render logic

绝不要对大面积的
```

绝不要在非活跃动画中使用
```
will-change
```
