app-store-kit@1.7.0

CAUTION

Publisher claims: "A Claude skill that takes an iOS/iPadOS app from code to the App Store and keeps it updated: code pre-check against Apple's rules, product page in every language, screenshots, build upload, and App Store Connect filled through the official API." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
