productivityGuided multi-platform app release lifecycle. Three-tier command architecture: /ship-advisor (strategic router), per-framework execution (/ship-flutter, /ship-pwa, /ship-snap, /ship-msstore, /ship-kmp, /ship-maui production-ready; /ship-swift roadmap stub), and /ship-everywhere (mass-publish orchestrator). 10 commands, 15 skills (6 framework-agnostic, 4 Flutter-coupled with TODO markers, 5 framework-specific: pwa-quality, msstore-submission, snap-build, kmp-build, maui-publishing; alt-distribution extended with Flathub coverage), 2 agents. Covers Codemagic/GitHub Actions CI/CD, Google Play + App Store + Microsoft Store + Snap Store + Flathub + alternative distribution, RevenueCat monetization, Shorebird code push (Flutter), Workbox/Lighthouse PWA quality, MSIX packaging via PWA Builder or native, snapcraft authoring, KMP iOS framework integration, MAUI multi-target builds, and pre-launch checklist based on Andrea Bizzotto's methodology.
