## What it does

This skill teaches coding agents how to bridge Google Play's three-tier subscription structure (Subscription, Base Plan, and Offer) into RevenueCat's Android object model. It guides the model through classes like `Offering`, `Package`, and `SubscriptionOption`, showing how to fetch catalogs with `awaitOfferings()` and initiate purchases using `PurchaseParams`.

It details offer selection logic and package iteration patterns. When passing a `Package`, `defaultOption` picks the longest trial or lowest initial cost while filtering out `rc-ignore-offer` tags. For win-back promotions, the skill demonstrates searching `subscriptionOptions` by tag with a fallback to `defaultOption`. It also covers prepaid plans requiring `pendingTransactionsForPrepaidPlansEnabled(true)`.

Google Play handles trial eligibility checks, meaning ineligible trial options simply do not show up in the SDK results. After a transaction completes, access verification relies on `customerInfo.entitlements` rather than raw subscription IDs.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add RevenueCat/ai-toolkit --skill rc-subscriptions -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/rc-subscriptions/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/rc-subscriptions/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add RevenueCat/ai-toolkit --skill rc-subscriptions -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/rc-subscriptions/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add RevenueCat/ai-toolkit --skill rc-subscriptions -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/rc-subscriptions/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install RevenueCat/ai-toolkit rc-subscriptions
```

2. **Manually: put the files in place**
- File: `.github/skills/rc-subscriptions/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add RevenueCat/ai-toolkit --skill rc-subscriptions -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/RevenueCat/ai-toolkit --path revenuecat-play-billing/skills/rc-subscriptions
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/rc-subscriptions/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add RevenueCat/ai-toolkit --skill rc-subscriptions -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/RevenueCat/ai-toolkit/tree/HEAD/revenuecat-play-billing/skills/rc-subscriptions/SKILL.md

## When to use it
- map Google Play subscription tiers to RevenueCat objects on Android
- configure paywalls using `offerings.current` or segment experiments
- target win-back or promotional offers via `subscriptionOptions` tags
- extract trial durations and formatted pricing from `pricingPhases`
- enable pending transactions for prepaid Google Play subscription plans

## Example prompts
- Show me how to fetch the current Offering and start a purchase for the monthly package in Kotlin.
- Write RevenueCat Android code to pick a win-back offer by tag with a fallback to `defaultOption`.
- How do I extract the trial period length and price from `PricingPhase`?

# Subscriptions on Android with RevenueCat

Google Play exposes subscriptions through a three tier hierarchy: Subscription, Base Plan, and Offer. RevenueCat wraps that hierarchy in a flatter model you configure from the dashboard: Offerings, Packages, and SubscriptionOptions. You fetch an Offering, pick a Package, and in most flows let the SDK choose the right SubscriptionOption for you.

## Phase 1: Understand

The mapping from Google Play to RevenueCat:

| Google Play | RevenueCat |
|---|---|
| Subscription (product ID) | `StoreProduct` |
| Base Plan | `SubscriptionOption` (base plan) |
| Offer | `SubscriptionOption` (offer) |
| Group of base plans grouped in dashboard | `Package` inside an `Offering` |

Key types you will touch:

- `Offering`: a dashboard configured group of `Package` objects. `offerings.current` is the one you show by default.
- `Package`: a purchasable slot (monthly, annual, weekly, custom). Exposes a `product: StoreProduct`.
- `StoreProduct`: the Google Play subscription product. Has `subscriptionOptions: List<SubscriptionOption>?` and a `defaultOption`.
- `SubscriptionOption`: either a base plan or an offer. Has `pricingPhases`, `tags`, and an `id`.
- `PricingPhase`: one billing segment (intro trial, intro price, or recurring). Has `billingPeriod`, `price`, `offerPaymentMode`, and `recurrenceMode`.

See the [Subscriptions chapter on revenuecat.com](https://www.revenuecat.com/guides/revenuecat-android-sdk/subscriptions-with-revenuecat) for the object model diagram showing the full Offerings hierarchy alongside the CustomerInfo hierarchy used for entitlement checks.

## Phase 2: Plan

Before you write code, map your paywall to the object model. Answer these three questions.

### 2.1 Which Offering drives the paywall?

- Default paywall: use `offerings.current`. This is the Offering marked current in the dashboard and is the standard choice.
