Todoist UI Skills

Todoist UI 设计指南

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

用于借助AI Agent构建Todoist风格界面的约束性设计指南。

When to Apply

适用场景

Reference these guidelines when:

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

在以下场景中请参考本指南：

构建浅色模式界面
创建Todoist风格的设计系统
实现采用Inter字体与4px网格的UI

Colors

色彩规范

SHOULD use light backgrounds for primary surfaces
MUST use
```
#FDFCFA
```
as page background (
```
surface-base
```
)
SHOULD reduce color palette (currently 20 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
页面背景必须使用
```
#FDFCFA
```
（对应语义化标记
```
surface-base
```
）
应精简色彩体系（当前检测到20种颜色）
为保障可访问性，文本对比度必须至少达到4.5:1

```
h-*
```

必须以1920px作为基础视口宽度进行设计
应使用统一的元素宽度：7px, 8px, 10px, 11px, 5px

```
h-screen
```
，需使用
