Appstore metadata sync

App Store Metadata Sync

Prefer canonical asc metadata JSON for app-info and version fields. Use .strings or fastlane flows only when specifically needed.

Use appstore-metadata-localizer when the main work is translation/adaptation across locales. Use appstore-release-notes-writer for What's New copy. Use appstore-subscription-localizer for subscription, group, or IAP display-name localizations.

Command Plan Helper

For a deterministic dry-run command plan, run the helper from the plugin root:

python3 "$PLUGIN_ROOT/skills/appstore-metadata-sync/scripts/metadata_sync_plan.py" \
  --app "APP_ID" --version "1.2.3" --platform IOS --dir "./metadata" \
  --app-info "APP_INFO_ID" --version-id "VERSION_ID" \
  --include-keywords --keywords-csv "./keywords.csv"

The helper prints commands only; it does not call ASC, mutate metadata, or read credentials. Pass --json for machine-readable output. Pass --confirming-actions only after manually verifying generated --confirm commands.

Workflow

1. Pull canonical metadata JSON into ./metadata before editing unless the user already provided a fresh metadata tree.
2. Resolve APP_INFO_ID when multiple app-info records exist.
3. Edit the owning JSON fields: app-info fields for name/subtitle/privacy text and version fields for description, keywords, marketing URL, promotional text, support URL, and What's New.
4. Validate locally, then run push --dry-run; apply/push without dry-run only after the diff and target app/version are confirmed.
5. Use alternate .strings or fastlane migration flows only for legacy repos or explicit user requests.

Limits: name/subtitle 30, keywords 100, description/What's New 4000, promotional text 170. Use table output for human verification and JSON for automation.
