### 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`。

## Beta/Preview Releases

Beta versions use `.preview` suffix (e.g., `55.0.0-preview.2`), published under `@next` tag.

Check if latest is beta: https://exp.host/--/api/v2/versions (look for `-preview` in `expoVersion`)

```bash
npx expo install expo@next --fix  # install beta
```

## Step-by-Step Upgrade Process

1. Upgrade Expo and dependencies

```bash
npx expo install expo@latest
npx expo install --fix
```

2. Run diagnostics: `npx expo-doctor`

3. Clear caches and reinstall

```bash
npx expo export -p ios --clear
rm -rf node_modules .expo
watchman watch-del-all
```

## Breaking Changes Checklist

- Check for removed APIs in release notes
- Update import paths for moved modules
- Review native module changes requiring prebuild
- Test all camera, audio, and video features
- Verify navigation still works correctly

## Prebuild for Native Changes

**First check if `ios/` and `android/` directories exist in the project.** If neither directory exists, the project uses Continuous Native Generation (CNG) and native projects are regenerated at build time — skip this section and "Clear caches for bare workflow" entirely.

If upgrading requires native changes:

```bash
npx expo prebuild --clean
```

This regenerates the `ios` and `android` directories. Ensure the project is not a bare workflow app before running this command.

## Clear caches for bare workflow

These steps only apply when `ios/` and/or `android/` directories exist in the project:

- Clear the cocoapods cache for iOS: `cd ios && pod install --repo-update`
- Clear derived data for Xcode: `npx expo run:ios --no-build-cache`
- Clear the Gradle cache for Android: `cd android && ./gradlew clean`

## Housekeeping

- Review release notes for the target SDK version at https://expo.dev/changelog
- If using Expo SDK 54 or later, ensure react-native-worklets is installed — this is required for react-native-reanimated to work.
- Enable React Compiler in SDK 54+ by adding `"experiments": { "reactCompiler": true }` to app.json — it's stable and recommended
- Delete sdkVersion from `app.json` to let Expo manage it automatically
- Remove implicit packages from `package.json`: `@babel/core`, `babel-preset-expo`, `expo-constants`.
- If the babel.config.js only contains 'babel-preset-expo', delete the file
- If the metro.config.js only contains expo defaults, delete the file

## Deprecated Packages

| Old Package          | Replacement                                          |
| -------------------- | ---------------------------------------------------- |
| `expo-av`            | `expo-audio` and `expo-video`                        |
| `expo-permissions`   | Individual package permission APIs                   |
| `@expo/vector-icons` | `expo-symbols` (for SF Symbols)                      |
| `AsyncStorage`       | `expo-sqlite/localStorage/install`                   |
| `expo-app-loading`   | `expo-splash-screen`                                 |
| expo-linear-gradient | experimental_backgroundImage + CSS gradients in View |

When migrating deprecated packages, update all code usage before removing the old package. For expo-av, consult the migration references to convert Audio.Sound to useAudioPlayer, Audio.Recording to useAudioRecorder, and Video components to VideoView with useVideoPlayer.

## expo.install.exclude

Check if package.json has excluded packages:

```json
{
  "expo": { "install": { "exclude": ["react-native-reanimated"] } }
}
```

Exclusions are often workarounds that may no longer be needed after upgrading. Review each one.
## Removing patches

Check if there are any outdated patches in the `patches/` directory. Remove them if they are no longer needed.

## Postcss

- `autoprefixer` isn't needed in SDK +53. Remove it from dependencies and check `postcss.config.js` or `postcss.config.mjs` to remove it from the plugins list.
- Use `postcss.config.mjs` in SDK +53.

## Metro

Remove redundant metro config options:

- resolver.unstable_enablePackageExports is enabled by default in SDK +53.
- `experimentalImportSupport` is enabled by default in SDK +54.
- `EXPO_USE_FAST_RESOLVER=1` is removed in SDK +54.
- cjs and mjs extensions are supported by default in SDK +50.
- Expo webpack is deprecated, migrate to [Expo Router and Metro web](https://docs.expo.dev/router/migrate/from-expo-webpack/).

## Hermes engine v1

Since SDK 55, users can opt-in to use Hermes engine v1 for improved runtime performance. This requires setting `useHermesV1: true` in the `expo-build-properties` config plugin, and may require a specific version of the `hermes-compiler` npm package. Hermes v1 will become a default in some future SDK release.

## New Architecture

The new architecture is enabled by default, the app.json field `"newArchEnabled": true` is no longer needed as it's the default. Expo Go only supports the new architecture as of SDK +53.
