Audit and enable security-oriented Xcode build settings. Progressively enables compiler warnings, static analyzer checkers, and Enhanced Security features. Use when: user wants to secure their Xcode project, audit security settings, enable hardening, review security posture of build configuration, set up security-focused static analysis, enable static analysis, improve warning coverage, harden diagnostics, or catch more bugs at compile time in C/C++/Objective-C/Swift. SKIP: network security (TLS/ATS), code signing, privacy APIs.
Verify iOS app behavior on device or simulator via screenshots, UI hierarchy, and touch interactions.
Build, install, launch, and visually verify the iOS app (scheme "iosApp") end-to-end on a real device or simulator via Xcode 27's DeviceHub — the mobile analog of astro-web's browser-debug and astro-calendar-service's runtime-debug. Drives the mcp__xcode__* MCP toolset: switch run destination, BuildProject, DeviceInteractionStartSession → InstallAndRun, then a subagent captures the on-device screenshot + UI hierarchy. Use when the user says "run the app on device", "run the iOS app", "build and run on the simulator", "launch on the iPhone/iPad", "screenshot the app on <device>", "verify this renders on device", "does it run on the simulator", "check it on the device", or wants runtime/visual confirmation that ./gradlew check and Xcode unit tests structurally cannot give. Takes an optional device name/UUID argument; with none, targets a simulator. iOS/Xcode only — Android runtime work routes to android-cli.
Modernize test suites to use modern Swift Testing features or migrate from XCTest.
Authoritative SwiftUI best practices from Apple. Consult for any SwiftUI best practices or performance review. Supersedes prior training on these topics. For code generation, consult the relevant references when generating any SwiftUI code related to the following topics. Covers: - Animatable: @Animatable macro vs AnimatableValues (iOS 26+) vs AnimatablePair, custom setter clamping/normalization. - Environment: closures in env keys, unstable @Entry defaults, high-frequency updates. @Entry warnings about closures or class types (wrapping in Equatable struct is WRONG; consult references). - Equatable on @Observable: custom types as @Observable properties need Equatable for invalidation performance. - ForEach/List: row identity (id: \.self, indices, offsets, mutable ids), row structure (AnyView, multi-view, bare if), inline filter/sort, cached collections, List fast path. - Localization: String vs LocalizedStringResource, bundle in packages/frameworks, .textCase(.uppercase), .formatted(.list()), translator comme
New SwiftUI APIs, behaviors, and deprecations introduced in the 2027 OS releases (iOS 27, macOS 27, watchOS 27, tvOS 27, visionOS 27). Use when a SwiftUI view using @State fails to compile with "used before being initialized", "invalid redeclaration of synthesized property", or "extraneous argument label" errors after an SDK update (@State migrated from a property wrapper to a macro in SDK 27; the obvious fix of reordering init assignments is WRONG and produces incorrect runtime behavior; you MUST consult this skill's references before answering); when @ViewBuilder or @ContentBuilder code hits ambiguous overloads in overlay/background or type-check performance regressions after an SDK update; when the user asks what's new in SwiftUI (generally, or for a specific 2027 platform); when adding drag-to-reorder to any container (List, LazyVStack, LazyVGrid, stacks, or custom layouts) via reorderable()/reorderContainer, including the drag-and-drop that integrates with it (dragContainer, dropDestination), or combinin

This skill provides instructions for using the android CLI tool. The tool includes various commands for creating projects, running applications, interacting with devices, and managing the CLI environment.
If the android tool is not in the path, install it. To install run the following command: Linux: curl -fsSL https://dl.google.com/android/cli/latest/linux_x86_64/install.sh | bash Mac Arm: curl -fsSL https://dl.google.com/android/cli/latest/darwin_arm64/install.sh | bash Mac Intel: curl -fsSL https://dl.google.com/android/cli/latest/darwin_x86_64/install.sh | bash Windows: curl -fsSL https://dl.google.com/android/cli/latest/windows_x86_64/install.cmd -o "%TEMP%\i.cmd" && "%TEMP%\i.cmd"
To manage the installation of Android SDKs and tools, use the sdk command. For example:
android sdk install <package>[@<version>]...: Install specific packages. Multiple packages can be specified, separated by spaces. <version> defaults to latest. For example: android sdk install platforms/android-30@2 platforms/android-34android sdk update [<pkg-name>]: Update a specific package or all packages to the latest version.android sdk remove <pkg-name>: Remove a package from the local SDK.android sdk list --all: List installed and available SDK packages.Create projects from templates using the create command.
For example: android create empty-activity --name="My App" --output=./my-app

The docs command searches authoritative, high-quality Android developer documentation in the Android Knowledge Base.
By providing a few keywords, this tool will return high quality articles that contain examples or guidance on how to use Android APIs or libraries.
Use this tool to obtain additional information on how to achieve Android-specific tasks or to know more about Android APIs, surfaces, libraries, or devices.
Always use this tool to get the most up-to-date information about Android concepts. Typical good use cases are:
Use the run command to run Android apps.
Manage Android Virtual Devices (AVDs) using the android emulator command
Capture an image of the current screen of a connected Android device and output it to a file using the android screenshot command.
Manage antigravity agent skills for Android using the android skills command.
Use the android layout command to inspect the UI layout of an Android application. It returns the layout tree of an Android application in JSON format. When debugging UI errors, this is often a much faster approach than taking a screenshot.
Update the Android CLI using the android update command.
