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 | $0.00053 | $0.00968 |
| Opus 5 | $0.00026 | $0.00484 |
| Sonnet 5 | $0.00011 | $0.00194 |
| Haiku 4.5 | $0.00005 | $0.00097 |
Grade A, and why
rc-payment-recovery 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 12d 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 — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Payment Recovery
Failed renewals on Google Play move a subscription through two states: grace period (user keeps access while Google retries the card) and account hold (access revoked until the user fixes the payment method). With RevenueCat, both states land in CustomerInfo automatically, and Google's in app message shows by default.
Phase 1: Understand
Three things happen when a renewal fails:
| State | Access | How RevenueCat surfaces it | User sees |
|---|---|---|---|
| Grace period | Retained | entitlement.isActive == true and billingIssueDetectedAt != null |
Google in app snackbar by default |
| Account hold | Revoked | entitlement.isActive == false and billingIssueDetectedAt != null |
Google in app snackbar by default |
| Recovered | Retained | billingIssueDetectedAt == null |
Nothing |
Two signals matter in the SDK:
EntitlementInfo.billingIssueDetectedAtis non null from the moment Google reports a billing problem until the user resolves it.EntitlementInfo.isActivetells you whether they still have access.
On the backend, a BILLING_ISSUE webhook fires once per transition. You do not decode RTDNs.
Phase 2: Plan
Before you write app code, decide what you actually need. Most apps need none.
Ask:
- Do you want the default Google in app message? If yes, do nothing. The SDK calls
showInAppMessagesIfNeededon BillingClient connect. - Do you want your own banner or dialog? If yes, read
billingIssueDetectedAtfromCustomerInfoand branch onisActive. - Do you want to gate the message to specific screens? If yes, disable the automatic call and invoke
showInAppMessagesIfNeeded(activity)yourself. - Do you need a server side flag (for example, to send a recovery email)? If yes, handle the
BILLING_ISSUEwebhook. No app code required.
If you only want the default behavior, stop here.
Phase 3: Execute
Default (recommended)
Leave automatic in app messages on. This is the default:
PurchasesConfiguration.Builder(context, apiKey)
.showInAppMessagesAutomatically(true)
.build()
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-payment-recovery is a skill published in the GitHub repository RevenueCat/ai-toolkit (65 stars, last pushed 10d ago), licensed MIT. It adds 53 tokens to every session and 968 once invoked, about $0.0003 per session on Opus 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.
