App Store Metadata Localizer

Pull source metadata, translate/adapt it, validate limits, get approval, then upload version or app-info localizations.

Use appstore-metadata-sync for canonical JSON field edits that are not translation-first. Use appstore-release-notes-writer when the requested artifact is only What's New or promotional text. Use appstore-subscription-localizer for subscription, group, or IAP display names.

Local Lint Helper

After writing or editing localized .strings or metadata JSON, run the bundled limit checker:

python3 "$PLUGIN_ROOT/skills/appstore-metadata-localizer/scripts/metadata_localization_lint.py" \
  "./localizations" "./app-info-localizations" --recursive

The helper checks App Store field limits for name, subtitle, keywords, description, whatsNew, and promotionalText. It does not translate, rewrite files, upload, or call ASC. Pass --json for machine-readable output.

Workflow

Confirm current asc localizations flags, then resolve app, version, and app-info IDs deterministically.
Download source and existing localizations; if download is unavailable, inspect with asc localizations list.
Translate one target locale at a time from the source locale. Preserve formatting and meaning; do not translate from memory.
Adapt keywords for native App Store search behavior instead of literal translation.
Run metadata_localization_lint.py, then show a field-by-locale summary table and wait for approval.
Upload only after approval, then verify with the matching asc localizations list command.

Translation Rules

Use formal, professional App Store register. Keep the app name unchanged unless the user explicitly asks to translate it. For updates, download current localization, show a diff, get approval, then upload.
