If you've ever had to click through 39 App Store Connect locales to set the same subscription display name in each language, this automates that entire process using the asc CLI tool. It walks you through listing your subscription groups and IAPs, checking which locales already have names, then bulk-creating localizations for all the missing ones with a single command per locale. The skill includes the full list of supported App Store locales and covers subscriptions, subscription groups, and in-app purchases. It's honestly just a systematic wrapper around repetitive asc commands, but that's exactly what you need when Apple makes you localize everything individually. Works for both creating new localizations and updating existing ones.
