### 导出副本边界与技能别名

迁移、安装、修复和经验回写只作用于当前加载的目标宿主技能副本。原 Codex 技能/MCP、下载的源码和 `original-skills` 均为来源材料，不因执行本副本而写入；只有用户另行明确要求配置 Codex 产品本身时，才按该产品流程处理指定目标。脚本需要安装目录或状态目录时，显式提供目标路径；不得从 `CODEX_HOME` 隐式推断写入位置。

跨技能名称可能沿用源库别名。先查 [技能别名表](../../skill-aliases.json)，优先选择同来源、同插件的条目，再使用其 `id` 调用或读取对应入口；不得假定旧 `$skill`、`superpowers:skill` 名称在新宿主直接注册。不能确定目标时先核对，不替换真实产品命令或 Shell 环境变量。

## 跨宿主使用约定

本副本供支持 Agent Skills 的客户端使用。先检查当前宿主实际提供的工具、权限和已连接服务，再执行正文工作流。原文中的宿主工具标识是能力参考；只有实际发现该工具时才可调用，其他宿主应使用经核验的等价 MCP、CLI 或 API。没有等价能力的步骤必须报告不可用，不能虚构调用或完成状态。

技能资源以本技能目录为基准；输出写入当前项目中用户指定的位置。通过技能名称或自然语言触发，具体快捷命令由宿主决定。涉及真实产品、模型 API、协议字段和官方网址的名称保持原意。授权、审批、隐私和工具范围限制在迁移后仍然有效；不得为兼容而扩大权限。具体依赖与迁移说明见同目录 `PORTABILITY.md`。

# SwiftUI Liquid Glass

## Overview
Use this skill to build or review SwiftUI features that fully align with the iOS 26+ Liquid Glass API. Prioritize native APIs (`glassEffect`, `GlassEffectContainer`, glass button styles) and Apple design guidance. Keep usage consistent, interactive where needed, and performance aware.

## Workflow Decision Tree
Choose the path that matches the request:

### 1) Review an existing feature
- Inspect where Liquid Glass should be used and where it should not.
- Verify correct modifier order, shape usage, and container placement.
- Check for iOS 26+ availability handling and sensible fallbacks.

### 2) Improve a feature using Liquid Glass
- Identify target components for glass treatment (surfaces, chips, buttons, cards).
- Refactor to use `GlassEffectContainer` where multiple glass elements appear.
- Introduce interactive glass only for tappable or focusable elements.

### 3) Implement a new feature using Liquid Glass
- Design the glass surfaces and interactions first (shape, prominence, grouping).
- Add glass modifiers after layout/appearance modifiers.
- Add morphing transitions only when the view hierarchy changes with animation.

## Core Guidelines
- Prefer native Liquid Glass APIs over custom blurs.
- Use `GlassEffectContainer` when multiple glass elements coexist.
- Apply `.glassEffect(...)` after layout and visual modifiers.
- Use `.interactive()` for elements that respond to touch/pointer.
- Keep shapes consistent across related elements for a cohesive look.
- Gate with `#available(iOS 26, *)` and provide a non-glass fallback.

## Review Checklist
- **Availability**: `#available(iOS 26, *)` present with fallback UI.
- **Composition**: Multiple glass views wrapped in `GlassEffectContainer`.
- **Modifier order**: `glassEffect` applied after layout/appearance modifiers.
- **Interactivity**: `interactive()` only where user interaction exists.
- **Transitions**: `glassEffectID` used with `@Namespace` for morphing.
- **Consistency**: Shapes, tinting, and spacing align across the feature.

## Implementation Checklist
- Define target elements and desired glass prominence.
- Wrap grouped glass elements in `GlassEffectContainer` and tune spacing.
- Use `.glassEffect(.regular.tint(...).interactive(), in: .rect(cornerRadius: ...))` as needed.
- Use `.buttonStyle(.glass)` / `.buttonStyle(.glassProminent)` for actions.
- Add morphing transitions with `glassEffectID` when hierarchy changes.
- Provide fallback materials and visuals for earlier iOS versions.

## Quick Snippets
Use these patterns directly and tailor shapes/tints/spacing.

```swift
if #available(iOS 26, *) {
    Text("Hello")
        .padding()
        .glassEffect(.regular.interactive(), in: .rect(cornerRadius: 16))
} else {
    Text("Hello")
        .padding()
        .background(.ultraThinMaterial, in: RoundedRectangle(cornerRadius: 16))
}
```

```swift
GlassEffectContainer(spacing: 24) {
    HStack(spacing: 24) {
        Image(systemName: "scribble.variable")
            .frame(width: 72, height: 72)
            .font(.system(size: 32))
            .glassEffect()
        Image(systemName: "eraser.fill")
            .frame(width: 72, height: 72)
            .font(.system(size: 32))
            .glassEffect()
    }
}
```

```swift
Button("Confirm") { }
    .buttonStyle(.glassProminent)
```
