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 | $0.00046 | $0.01085 |
| Opus 5 | $0.00023 | $0.00543 |
| Sonnet 5 | $0.00009 | $0.00217 |
| Haiku 4.5 | $0.00005 | $0.00109 |
Grade A, and why
rc-price-changes 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 10d 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.

Price Changes
Use this skill when you roll out a new price for an existing subscription product on Android and want RevenueCat to manage the cohort and consent plumbing for you.
Phase 1: Understand
Google Play supports two kinds of price changes for active subscribers:
- Opt out changes (typically decreases, and increases within Google's opt out threshold). The new price applies automatically at the next renewal. No user action required.
- Opt in changes (larger increases). Google shows its own in app consent dialog. If the user consents, they continue at the new price. If they decline, the subscription cancels at period end.
RevenueCat processes SUBSCRIPTION_PRICE_CHANGE_UPDATED and related RTDNs on its backend and updates CustomerInfo when a subscriber's cohort or consent state changes. Your app reads entitlements the same way it always does.
For most price change scenarios, there is nothing to implement in your app or backend.
Phase 2: Plan
Decide which path applies before you touch anything.
| Question | Opt out | Opt in |
|---|---|---|
| Typical trigger | Decrease, or small increase within Google's threshold | Larger increase above Google's threshold |
| User consent | Not required | Required, prompted by Google Play UI |
| If user declines | N/A | Subscription cancels at period end, CANCELLATION webhook fires |
| New price applies | Automatically at next renewal | After user consents in Play's dialog |
| RTDN RevenueCat consumes | SUBSCRIPTION_PRICE_CHANGE_UPDATED |
SUBSCRIPTION_PRICE_CHANGE_UPDATED, then SUBSCRIPTION_CANCELED if declined |
| App code change | None required | None required |
| Paywall price source | pkg.product.price.formatted (new purchases only) |
pkg.product.price.formatted (new purchases only) |
Questions to answer before executing:
- Is the change a decrease, a small increase, or a larger increase? That determines opt out vs opt in.
- Do you want to notify existing subscribers in app before the change takes effect? That is optional, driven by a webhook or a Targeting rule, not a requirement.
- Which legacy cohorts exist today? Existing subscribers keep paying their old price until Google migrates them. This is a Google Play concern, not visible in the SDK.
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-price-changes is a skill published in the GitHub repository RevenueCat/ai-toolkit (65 stars, last pushed 8d ago), licensed MIT. It adds 46 tokens to every session and 1,085 once invoked, about $0.0002 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.
