## What it does

The skill steers the agent toward the modern Swift StoreKit 2 surface: `Product`, `Transaction`, `PurchaseAction`, `StoreView` and `SubscriptionStoreView`. It tells you to leave the original `SKProduct` and `SKPaymentQueue` APIs alone unless an older OS version forces your hand.

Covered inside: product types (consumable, non-consumable, auto-renewable, non-renewing), fetching items with `Product.products(for:)`, every `PurchaseResult` branch, the `Transaction.updates` listener, and entitlement checks through `Transaction.currentEntitlements`. Separate sections handle restore purchases, subscription status, Family Sharing, Ask to Buy, refunds and billing retry.

Start the `Transaction.updates` listener when the app launches, not when a paywall appears. A purchase made on another device, or an Ask to Buy approval, will otherwise slip past. For custom SwiftUI buttons the skill reaches for `PurchaseAction` from the environment; on watchOS it uses `product.purchase(options:)`.

## When to use it
- build a paywall with `SubscriptionStoreView` instead of hand-rolled UI
- handle every `PurchaseResult` branch, `.pending` included
- check active entitlements via `Transaction.currentEntitlements`
- wire the `Transaction.updates` listener at app launch
- work through Family Sharing, Ask to Buy and refunds

## Example prompts
- Build a subscription screen with `SubscriptionStoreView` for monthly and yearly plans
- Add a premium entitlement check using `Transaction.currentEntitlements`
- Handle a consumable purchase and cover the `.pending` case
