If you've ever had to click through 38 different language settings in App Store Connect just to set the same subscription name everywhere, this will save you an hour of your life. It wraps the asc CLI to bulk-create localizations for subscriptions, subscription groups, and in-app purchases across all supported App Store locales. You still need to have your subscription groups and products already set up, and you'll need asc auth configured, but once that's done you can push a display name to every locale with a series of commands instead of the web UI nightmare. The skill provides the full locale list and handles the tedious check-then-create workflow to avoid duplicate errors.
