SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Keeping App Store metadata consistent between local files and App Store Connect is error-prone, especially across multiple locales, app-info records, and version localizations. This Skill standardizes the pull-edit-validate-push cycle so metadata changes are reviewed and applied safely. ## Core Features & Use Cases - Canonical metadata workflow: Pull app-info and version localization JSON files, edit them locally, validate against App Store field limits, and push with dry-run previews. - Review-gated apply: Generate review artifacts with asc metadata plan, approve selectively by key or scope, and apply only after explicit confirmation. - Keyword and quick-edit flows: Diff and apply keyword-only updates, import keyword research from CSV, or make one-off field edits with explicit version selectors. - Use Case: You need to update the en-US description and keywords for version 1.2.3. Pull the canonical metadata, edit the JSON files, run validation, preview with a dry run, then push the changes to App Store Connect. ## Quick Start Ask the agent to pull the App Store metadata for your app and version, update the description and keywords, validate the changes, and push them after a dry-run preview.

FAQPage Schema

Can I migrate legacy fastlane metadata to App Store Connect?▼

How do I review metadata changes before applying them?▼

Use asc metadata plan to create a review artifact, then asc metadata approve to approve all changes or specific keys and scopes, and asc metadata status to inspect the review state. Apply with asc metadata apply --confirm once approved.
