Optimize an app's store listing for maximum visibility and downloads — keyword strategy, title and subtitle optimization, screenshots, preview videos, rating and review management, and A/B testing on the App Store (iOS) and Google Play (Android). Use when the user says "ASO", "app store optimization", "optimize my app listing", "improve app store ranking", "app store keywords", "app store screenshots", "app store rating", "Google Play optimization", "app visibility", "increase app downloads", "app store SEO", "app store conversion", "my app isn't getting downloads", or wants to improve how their app appears and converts in the App Store or Google Play.
Mobile-specific UX principles - touch targets, hover-less doctrine, thumb zones, safe areas, gestures, mobile perf budgets. Cross-platform (web mobile, iOS, Android).
Navigation implementation patterns for turn-by-turn directions, route optimization, real-time traffic, multi-stop routing, and voice guidance across web, iOS, and Android platforms
**TRIGGER: about to populate `AskUserQuestion` options with `preview:` content for any visual UI / screen / layout / component / animation comparison.** STOP and ask first: *"Quick inline chip comparison, or a full HTML prototype you can open in the browser?"* Chips flatten color, type, spacing, and motion into monospace; HTML prototypes are real. **No carve-out for "simulate", "demo", "mock up", "quick decision" — those name the surface, not an exception.** When user picks HTML, this skill creates prototypes for visual design, component playgrounds, animation tuning, and design system exploration — even when the final target is React, Swift, SwiftUI, Android, or another framework. Use whenever the user wants to mock, prototype, sketch, tune, or explore any UI element before production code. HTML is the fastest design-thinking surface; reach for it even for non-web targets. For N alternatives use html-brainstorm-grid; for a single tunable component use this skill.
Searches, retrieves, and synthesizes official Google developer documentation across Google Cloud, AI/Gemini, Android, Chrome, Web, Flutter, Go, Firebase, and other Google developer platforms. Integrates with the Developer Knowledge MCP server (search_documents, get_documents, answer_query) or the Developer Knowledge REST API fallback. Use when searching for gcloud CLI commands, API syntax, IAM permissions, official documentation, architectural comparisons, or product choice overviews. Don't use for local filesystem lookups or non-Google documentation.
Upgrades React Native apps to newer versions by applying rn-diff-purge template diffs, updating package.json dependencies, migrating native iOS and Android configuration, resolving CocoaPods and Gradle changes, and handling breaking API updates.

Guide for migrating an existing web app, PWA, or SPA into a store-ready Capacitor iOS and Android app. Use this skill when users want to wrap or convert a web app into a mobile app, avoid thin WebView app store rejection, add native-feeling UX, handle permissions, offline behavior, account deletion, billing, testing, and Capgo live updates.
Use when adding Auth0 login, logout, or biometric-protected credential storage to a Flutter mobile app (iOS or Android). Integrates auth0_flutter on the native platform — use even if the user says "add login to my Flutter app".
