Set up a complete RevenueCat project from scratch — creates apps, products, entitlements, offerings, and packages in the correct order. Use when the user wants to create a new RevenueCat project, configure in-app purchases, set up subscriptions or monetization, or bootstrap IAP infrastructure for iOS, Android, or Web.

End-to-end RevenueCat integration — sets up the dashboard side via the RevenueCat MCP or the `rc` CLI (project, app, public API key) and installs/configures the Purchases SDK in the app. Use when the user asks to add RevenueCat, hook up RevenueCat, add subscriptions or in-app purchases to an app, integrate Purchases, install the RevenueCat SDK, set up a RevenueCat API key, configure Purchases on launch, or set up a brand new RevenueCat integration on iOS, Android, Kotlin Multiplatform, Flutter, or React Native.

Use this skill when selling one time products on Android with RevenueCat. Covers fetching offerings, running awaitPurchase on a non subscription package, and relying on the SDK to acknowledge or consume automatically.

Use this skill when handling failed renewals on Android with RevenueCat. Covers how Grace Period and Account Hold are reflected in CustomerInfo automatically, when to prompt the user, and how to trigger Google's in app messaging via showInAppMessages.

Use this skill when implementing subscription upgrades, downgrades, and plan switches via RevenueCat on Android. Covers GoogleProductChangeInfo, picking a Google replacement mode, and letting the SDK manage linkedPurchaseToken chaining.

Use this skill when rolling out subscription price changes on Android with RevenueCat. Covers opt out decreases versus opt in increases, RevenueCat's automatic handling of the change confirmation flow, and the dashboard configuration involved.

Use this skill as a quick reference for the RevenueCat Android SDK 10.x and REST API. Covers SDK init, common Purchases calls, CustomerInfo / Offerings access patterns, and the most used REST endpoints.

Use this skill to decide whether to use RevenueCat or raw Google Play Billing on Android. Provides a side by side reference of what RevenueCat handles versus what remains your responsibility at both client and backend layers.

Covers Trusted Entitlements response verification (INFORMATIONAL vs ENFORCED), why the server is always the authority, API key hygiene (public SDK key vs secret REST key), anonymous user identity, and purchase token protections RevenueCat provides automatically.

Use this skill when setting up a RevenueCat project for Android: creating the app in the dashboard, uploading the Google Play service account credentials, configuring entitlements and offerings, and getting the public SDK API key for the Android app.

Use this skill when modeling subscriptions through RevenueCat's object model on Android. Covers Offerings, Packages, StoreProduct, SubscriptionOption, PricingPhase, and how they map to Google Play's Subscription, Base Plan, and Offer hierarchy.

Use this skill when gating access based on RevenueCat subscription state on Android. Covers reading CustomerInfo, checking entitlement.isActive as the single source of truth for access, and drilling into willRenew, periodType, and expirationDate when deeper logic is needed.

Use this skill when testing a RevenueCat Android integration. Covers the RevenueCat Test Store (test_ API key prefix, in dialog Success/Fail/Cancel choice), mockk based unit testing with an interface wrapper around Purchases, and a GitHub Actions CI pattern. Avoids Google Play sandbox for day to day test iteration.
