Asc Metadata Sync

This is the skill you want if you're managing App Store metadata programmatically and need to keep local files in sync with App Store Connect. It uses a canonical JSON format for app-info and version localizations, validates everything before upload, and supports dry-run previews so you don't push garbage. The workflow is pull, edit, validate, push. It also handles legacy fastlane metadata migration and lower-level .strings files if you need them, but the modern path is cleaner. Character limits are baked into validation. Honestly, the command surface is large, but the common case of syncing descriptions and keywords is straightforward once you pick between metadata pull/push versus the lower-level localization commands.
