msw-packages

MSWPackages catalog — official 1st-party prebuilt packages for common MSW features. Use this skill BEFORE writing a feature from scratch when the user asks for any standard game system (toast/notification, ranking/leaderboard, inventory/equipment, shop/store, world shop, mail, quest/achievement, dialog/NPC conversation, key binding, game event broadcast, player data/save, collection/dex, slash command, scrollview/virtualized list, drop table, global config, GM message, resource/currency, UI components). Always check the catalog first; if a package matches the requested feature, fetch its README and propose integrating instead of building from zero. Keywords: MSWPackages, package, prebuilt, integration.
