asc-metadata-sync

The asc-metadata-sync skill helps teams keep App Store metadata aligned with App Store Connect using the current canonical metadata workflow. It is designed for syncing, validating, and applying metadata changes across app-level and version-level localization content while reducing manual update errors. This skill is especially useful when updating App Store listing content such as names, subtitles, descriptions, keywords, promotional text, or support links, and also supports teams migrating from legacy fastlane metadata into the newer canonical structure. By organizing metadata into local files and validating changes before upload, it creates a repeatable workflow for maintaining consistency between source-controlled metadata and App Store Connect.

Its core capabilities include pulling canonical metadata into a local directory, editing localized JSON files, validating metadata before upload, previewing changes through dry runs, and applying updates back to App Store Connect. It also supports a keyword-focused workflow for comparing, importing, and syncing keywords independently when only keyword metadata needs updating. For targeted changes, the skill includes quick field update workflows for editing version-localization content or app-info fields without running a full metadata sync. Lower-level localization and migration commands remain available when `.strings` files or legacy fastlane-format metadata are specifically required.

This skill is intended for developers, release engineers, App Store operations teams, and product or marketing contributors responsible for App Store metadata management. It is particularly valuable for teams managing localized metadata across multiple versions, maintaining metadata as part of a release workflow, or migrating existing metadata pipelines to the current asc canonical metadata structure. It works well in environments where metadata is reviewed locally before validation and deployment.
