Add secure storage to .NET MAUI apps using SecureStorage.Default. Covers SetAsync, GetAsync, Remove, RemoveAll, platform setup (Android backup rules, iOS Keychain entitlements, Windows limits), common pitfalls, and a DI wrapper service for testability. USE FOR: "secure storage", "SecureStorage", "store token securely", "Keychain", "Android Keystore", "save secret", "encrypted storage", "store credentials", "sensitive data storage". DO NOT USE FOR: general file storage (use maui-file-handling), SQLite databases (use maui-sqlite-database), or authentication flows (use maui-authentication).

Add speech-to-text voice input to .NET MAUI apps using CommunityToolkit.Maui. Covers speech recognition, microphone permissions, and hands-free text entry. Works with any UI pattern (XAML/MVVM, C# Markup, MauiReactor). USE FOR: "speech to text", "voice input", "speech recognition", "microphone input", "voice command", "dictation", "SpeechToText", "hands-free text", "transcribe speech". DO NOT USE FOR: text-to-speech output (different feature), media playback (use maui-media-picker), or general permissions (use maui-permissions).

End-to-end workflow for building, deploying, inspecting, and debugging .NET MAUI and MAUI Blazor Hybrid apps as an AI agent. Use when: (1) Building or running a MAUI app on iOS simulator, Android emulator, Mac Catalyst, macOS (AppKit), or Linux/GTK, (2) Inspecting or interacting with a running app's UI (visual tree, tapping, filling text, screenshots, property queries), (3) Debugging Blazor WebView content via CDP, (4) Managing simulators or emulators, (5) Setting up MauiDevFlow in a MAUI project, (6) Completing a build-deploy-inspect-fix feedback loop, (7) Handling permission dialogs and system alerts, (8) Managing multiple simultaneous apps via the broker daemon. Covers: maui devflow CLI (the `maui` dotnet global tool, `devflow` subcommand), androidsdk.tool, appledev.tools, adb, xcrun simctl, xdotool, and dotnet build/run for all MAUI target platforms including macOS (AppKit) and Linux/GTK.

Use this skill when the user is working with an Aspire distributed application and needs to operate the AppHost or its resources through the Aspire CLI: start, restart, stop, or wait on the app; work through code/resource changes with watch, rebuild, hot reload, or resource commands; inspect resources, logs, traces, docs, or health; add integrations; manage secrets or config; publish, deploy, or rerun a named pipeline step; initialize Aspire in an existing app; recover missing `.modules` files in a TypeScript AppHost; discover the right frontend URL for Playwright from Aspire state; expose custom dashboard/resource commands; or understand unfamiliar Aspire AppHost APIs in C# or TypeScript. Use it even if they describe the task in terms of an AppHost, resources, dashboard, existing app bootstrap, missing generated modules, Playwright URL discovery, C# API understanding, or local distributed app workflow without explicitly naming Aspire. Do not use it for non-Aspire .NET apps, container-only repos with no AppHo
