# Google Mobile Ninja

**Jump Skill** — Master orchestrator that routes mobile development tasks to 35+ specialized skills from official Google repositories.

## Purpose

This skill acts as an intelligent router to the Android, Flutter, and Dart skills library. Instead of manually searching for the right skill, describe your mobile dev task and this skill will:

1. Identify the most relevant specialized skill(s)
2. Load the full skill instructions on demand
3. Execute the task with expert-level mobile knowledge

## Routing Logic

When a task arrives:

1. **Jetpack Compose?** → `jetpack-compose`
2. **Android Navigation?** → `compose-navigation`
3. **Camera/CameraX?** → `camerax`
4. **AGP/Gradle upgrade?** → `agp-9-upgrade`
5. **App size/R8?** → `r8-analyzer`
6. **Android profiling?** → `android-profiler`
7. **Sign-in/Identity?** → `identity`
8. **Play Store?** → `play`
9. **Flutter new app?** → `flutter-create-app`
10. **Flutter widget?** → `flutter-widget-guide`
11. **Flutter state?** → `flutter-state-management`
12. **Flutter test?** → `flutter-add-test`
13. **Flutter debug?** → `flutter-fix-bug`
14. **Dart package?** → `dart-create-package`
15. **Dart test?** → `dart-add-unit-test`

## Execution Pattern

```
1. Announce: "Routing to [skill-name]..."
2. Load: Read the SKILL.md from the path in the catalog
3. Execute: Follow the skill's instructions
4. Cite: Reference the skill in the response
```

## Quick Reference

| Task | Route To |
|------|----------|
| Build Compose UI | `jetpack-compose` |
| Setup navigation | `compose-navigation` |
| Add camera feature | `camerax` |
| Upgrade AGP | `agp-9-upgrade` |
| Reduce APK size | `r8-analyzer` |
| Create Flutter app | `flutter-create-app` |
| Add Flutter feature | `flutter-add-feature` |
| Flutter state management | `flutter-state-management` |
| Write Flutter tests | `flutter-add-test` |
| Create Dart package | `dart-create-package` |
