What problem does it solve? Keeping App Store Connect (ASC) and RevenueCat catalogs in sync is error-prone: product identifiers drift, entitlements get misattached, and missing ASC metadata blocks RevenueCat mapping. This Skill audits both systems, builds a deterministic diff, and applies approved changes safely. ## Core Features & Use Cases - Read-only drift audit: Compare ASC subscription groups, subscriptions, and IAPs against RevenueCat apps, products, entitlements, offerings, and packages, then present a no-write reconciliation plan. - Guided apply mode: Create missing ASC groups, subscriptions, and IAPs with pricing, localizations, and review screenshots, then map them to RevenueCat products, entitlements, and offerings in a fixed order. - Strict validation gates: Run asc validate subscriptions and asc validate iap in strict mode and block RevenueCat mapping until both exit cleanly. - Use Case: Before a release, audit your ASC catalog against RevenueCat, create a missing annual subscription with pricing and localization, validate it, then attach it to the premium entitlement and $rc_annual package. ## Quick Start Ask the agent to audit your App Store Connect subscriptions and IAPs against your RevenueCat project and show what is missing on either side.
