// Scaffold, build, and package SwiftPM-based macOS apps without an Xcode project. Use when you need a from-scratch macOS app layout, SwiftPM targets/resources, a custom .app bundle assembly script, or signing/notarization/appcast steps outside Xcode.
Expert guidance on Swift Testing for writing, reviewing, migrating, and debugging tests. Use when developers mention Swift Testing, @Test, @Suite,
Operate the Ducko XMPP CLI tool. Use when asked to send XMPP messages, start an interactive XMPP session, list accounts, check roster, view history, manage presence, or test the CLI. Covers running commands, authentication, output formats, and all subcommands.
End-to-end UI testing for the Ducko macOS app using pre-built helper scripts. This skill should be used when the user asks to "test ducko", "test the app", "run E2E tests", "test the app end-to-end", "test the UI", "send a test message", or wants to verify DuckoApp works from login through messaging.
Background-safe macOS app UI testing using Peekaboo CLI and osascript. This skill should be used when the user asks to "test the app UI", "check the UI", "interact with the running app", "take a screenshot of the app", "fill in the form", "click the button", "verify the UI state", "automate the app", or wants to automate interaction with a running macOS application without stealing keyboard/mouse focus from the user.
Use when working with iOS/macOS Keychain Services (SecItem queries, kSecClass, OSStatus errors), biometric authentication (LAContext, Face ID, Touch ID), CryptoKit (AES-GCM, ChaChaPoly, ECDSA, ECDH, HPKE, ML-KEM), Secure Enclave, secure credential storage (OAuth tokens, API keys), certificate pinning (SecTrust, SPKI), keychain sharing across apps/extensions, migrating secrets from UserDefaults or plists, or OWASP MASVS/MASTG mobile compliance on Apple platforms.
Expert guidance on Swift Concurrency correctness, modern API usage, and async/await pitfalls in Swift 6.2+. Use when developers mention async/await, actors, tasks, @MainActor, Sendable, isolation, Swift 6 migration, strict concurrency diagnostics, AsyncSequence/AsyncStream, async_without_await lint warnings, or data-race issues.

Use assets/templates/bootstrap/ for the starter layout and references/packaging.md + references/release.md for packaging and release details.
Bootstrap the project folder
assets/templates/bootstrap/ into a new repo.MyApp in Package.swift, Sources/MyApp/, and version.env.APP_NAME, BUNDLE_ID, and versions.Build, package, and run the bootstrapped app
assets/templates/ into your repo (for example, Scripts/).swift build and swift test.Scripts/package_app.sh.Scripts/compile_and_run.sh (preferred) or Scripts/launch.sh.Scripts/sign-and-notarize.sh and Scripts/make_appcast.sh.assets/templates/package_app.sh: Build binaries, create the .app bundle, copy resources, sign.assets/templates/compile_and_run.sh: Dev loop to kill running app, package, launch.assets/templates/build_icon.sh: Generate .icns from an Icon Composer file (requires Xcode install).assets/templates/sign-and-notarize.sh: Notarize, staple, and zip a release build.assets/templates/make_appcast.sh: Generate Sparkle appcast entries for updates.assets/templates/setup_dev_signing.sh: Create a stable dev code-signing identity.assets/templates/launch.sh: Simple launcher for a packaged .app.assets/templates/version.env: Example version file consumed by packaging scripts.assets/templates/bootstrap/: Minimal SwiftPM macOS app skeleton (Package.swift, Sources/, version.env).CFBundleVersion), so BUILD_NUMBER in version.env must increase for each update.MENU_BAR_APP=1 when packaging to emit LSUIElement in Info.plist.
