Baseline UI

Baseline UI

Enforces an opinionated UI baseline to prevent AI-generated interface slop.

强制执行一套有明确主张的UI基线规范，避免AI生成的界面质量低下问题。

How to use

使用方法

```
/baseline-ui
```
Apply these constraints to any UI work in this conversation.
```
/baseline-ui <file>
```
Review the file against all constraints below and output:
- violations (quote the exact line/snippet)
- why it matters (1 short sentence)
- a concrete fix (code-level suggestion)

```
/baseline-ui
```
将这些约束应用到本次对话中的所有UI相关工作。
```
/baseline-ui <file>
```
对照以下所有约束审查指定文件，并输出：
- 违规项（引用准确的行/代码片段）
- 问题影响（1句简短说明）
- 具体修复方案（代码级建议）

Stack

技术栈

MUST use Tailwind CSS defaults unless custom values already exist or are explicitly requested
MUST use
```
motion/react
```
(formerly
```
framer-motion
```
) when JavaScript animation is required
SHOULD use
```
tw-animate-css
```
for entrance and micro-animations in Tailwind CSS
MUST use
```
cn
```
utility (
```
clsx
```
+
```
tailwind-merge
```
) for class logic

除非已有自定义值或明确要求，否则必须使用Tailwind CSS默认配置
需要JavaScript动画时必须使用
```
motion/react
```
（原
```
framer-motion
```
）
Tailwind CSS中的入场动画和微动画应该使用
```

Components

组件规范

MUST use accessible component primitives for anything with keyboard or focus behavior (
```
Base UI
```
,
```

```
,
```

NEVER mix primitive systems within the same interaction surface
SHOULD prefer
```
Base UI
```
for new primitives if compatible with the stack
MUST add an
```
aria-label
```
to icon-only buttons
NEVER rebuild keyboard or focus behavior by hand unless explicitly requested

所有涉及键盘或焦点行为的组件必须使用可访问组件库实现（
```
Base UI
```
、
```
React Aria
```
、
```

```
）
必须优先使用项目现有组件库
禁止在同一个交互面混用不同的组件基础库
如果和技术栈兼容，新组件应该优先选用
```
Base UI
```
纯图标按钮必须添加
```
aria-label
```
属性
除非明确要求，否则禁止手动实现键盘或焦点行为

Interaction

交互规范

MUST use an
```

```
safe-area-inset
```

MUST show errors next to where the action happens
NEVER block paste in
```
input
```
or
```
textarea
```
elements

涉及破坏性或不可逆操作时必须使用
```
AlertDialog
```

禁止使用
```
h-screen
```
，请使用
```
h-dvh
```
