.NET MAUI safe area and edge-to-edge layout guidance for .NET 10+. Covers the new SafeAreaEdges property, SafeAreaRegions enum, per-edge control, keyboard avoidance, Blazor Hybrid CSS safe areas, migration from legacy iOS-only APIs, and platform-specific behavior for Android, iOS, and Mac Catalyst. USE FOR: "safe area", "edge-to-edge", "SafeAreaEdges", "SafeAreaRegions", "keyboard avoidance", "notch insets", "status bar overlap", "iOS safe area", "Android edge-to-edge", "content behind status bar", "UseSafeArea migration", "soft input keyboard", "IgnoreSafeArea replacement". DO NOT USE FOR: general layout or grid design (use Grid and StackLayout), app lifecycle handling (use maui-app-lifecycle), theming or styling (use maui-theming), or Shell navigation structure.
Set up a testing environment for RevenueCat purchases without charging real money. Use when the user says test RevenueCat purchases, sandbox setup, StoreKit configuration file, license tester, how do I test purchases without real money, set up sandbox account, internal testing track, or test paywall on iOS, Android, Kotlin Multiplatform, Flutter, or React Native.
Design to iOS and Android conventions — what each OS mandates, where they diverge, and when to unify. Use when shipping native apps. For breakpoint adaptation use `responsive-design`; for matching competitor patterns use `jakobs-law` (interaction-design).
The React Native / Expo CLI for AI agents. Use when running or building a React Native or Expo app on a simulator, emulator, or device, including expo run:ios, expo run:android, react-native run-ios, react-native run-android, expo start, and Metro; when reading build, launch, redbox, or runtime errors from the app logs; when working in parallel worktrees; or when identifying the correct device for UI interaction.
Create App Store and Play Store screenshots and preview videos for an iOS or Android app. goldie explores the app on a simulator or emulator, writes argent flows, renders framed screenshots and a preview video, and opens a local studio with the finished store page. Use this skill when the user asks for store screenshots, store assets, a preview video, or mentions goldie. Also use it to change assets goldie made before: new headlines, a different background or bezel, or a new screenshot order. Run it from the mobile app's repo.
Implement, configure, and secure Sign In With Google (SiwG) using Google Identity Services (GIS / `https://accounts.google.com/gsi/client`) across web architectures. Use when creating Google sign-in buttons, implementing Google One Tap with FedCM, integrating GIS in React/Next.js/Angular/HTML, verifying ID tokens on backend runtimes (Python/Node.js/Go/Java), enforcing Google Workspace domain restrictions (`hd`), securing client-side ID tokens via WebCrypto nonces or encrypted IndexedDB, embedding in cross-origin iframes via the Intermediate Iframe API (`https://accounts.google.com/gsi/intermediate`), configuring Content Security Policy (CSP), COOP, and Permissions Policy (`identity-credentials-get`) headers, or handling sign-out and revocation. Don't use for legacy Google Sign-In (`gapi.auth2`), Google Cloud IAM service accounts, or Android/iOS native Credential Manager.
Guides the agent through connecting an MCP client to the hosted, unofficial Ionic Framework MCP server by Capawesome, which serves the official Ionic Framework documentation for v9 and v8, the component API reference, the official usage examples for Angular, React, Vue and vanilla JavaScript, and the Ionic blog. Covers client detection, setup for Claude Code, Claude Desktop, Cursor, VS Code, Windsurf, Zed and stdio-only clients, documentation version selection, verification, and troubleshooting. Do not use for Capacitor plugins or native iOS and Android configuration, upgrading or migrating apps to a newer version, Capawesome Cloud, or MCP servers other than the Ionic Framework one.
Guides authoring, review, optimization, and false-positive debugging of YARA-X detection rules for malware identification across PE, script, npm, Office, Chrome extensions (crx module), and Android DEX (dex module). Covers string and atom quality, condition short-circuiting, legacy YARA migration, yarGen/FLOSS workflows, goodware validation, and production deployment—not full malware reverse engineering, network IDS (Suricata/Snort), or memory forensics (Volatility). Use when the user asks to write YARA rule, YARA-X, yr check, yr scan, false positive YARA, yarGen, malware detection rule, crx module, dex module, optimize YARA performance, or migrate legacy YARA.
A Google Play Store API alternative on fetcher.sh — pay-per-call in USDC via x402, or prepaid credits with a Bearer key, no Google Play Console access. Use when the user wants to search Android apps by keyword with price (free/paid) and country storefront filters, fetch an app's full details, reviews sorted by newest/rating/helpfulness, permissions, or data safety disclosure, list apps similar to a given app, or fetch a developer's app catalog. Also covers Android app store optimization (ASO) research, competitor app monitoring, review sentiment input, and app discovery without Google Play Console developer access.
Compose and Compose Multiplatform expert for UI development across Android, Desktop, iOS, and Web. Use whenever the user mentions Compose APIs (@Composable, remember, LaunchedEffect, NavHost, MaterialTheme, LazyColumn, Modifier, recomposition), Compose Multiplatform (commonMain, expect/actual, Res.*, ComposeUIViewController, UIKitView, ComposeViewport), Android TV (tv-material, D-pad, focus, Carousel), Material 3 motion, atomic design systems, design-to-code workflows, Paging 3, or navigation. Activates Review Mode on GitHub PR URLs and review phrases ("review this PR", "what's wrong with this"). Auto-detects Compose projects on session_start. Backed by actual androidx/androidx and JetBrains/compose-multiplatform-core source receipts. See "## When this skill applies" in SKILL.md for the full trigger surface.
Integrate Cartridge Controller into native mobile applications (iOS, Android, React Native) and web wrappers (Capacitor). Use when building mobile games or apps that need Controller wallet functionality with local keypair signing. Covers SessionConnector for native auth flows, Controller.c FFI bindings, passkey configuration with Apple App Site Association, and platform-specific setup.
React Native and Expo patterns for building performant mobile apps. Covers list performance, animations with Reanimated, navigation, UI patterns, state management, platform-specific code, and Expo workflows. Use when building or reviewing React Native code. Triggers: 'react native', 'expo', 'mobile app', 'react native performance', 'flatlist', 'reanimated', 'expo router', 'mobile development', 'ios app', 'android app'.
