Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00051 | $0.01818 |
| Opus 5.5 | $0.00020 | $0.00727 |
| Sonnet 5.5 | $0.00010 | $0.00364 |
| Haiku 4.5 | $0.00005 | $0.00182 |
Grade A, and why
rc-subscriptions scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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 ofPackageobjects.offerings.currentis the one you show by default.Package: a purchasable slot (monthly, annual, weekly, custom). Exposes aproduct: StoreProduct.StoreProduct: the Google Play subscription product. HassubscriptionOptions: List<SubscriptionOption>?and adefaultOption.SubscriptionOption: either a base plan or an offer. HaspricingPhases,tags, and anid.PricingPhase: one billing segment (intro trial, intro price, or recurring). HasbillingPeriod,price,offerPaymentMode, andrecurrenceMode.
See the Subscriptions chapter on revenuecat.com 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. - Experiment or segment specific paywall: fetch
offerings.all["experiment-a"]. You keep the dashboard in charge of which products appear, so no app update ships when the catalog changes.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

rc-subscriptions is a skill published in the GitHub repository RevenueCat/ai-toolkit (76 stars, last pushed today), licensed MIT. It adds 51 tokens to every session and 1,818 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
