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 | $0.00026 | $0.00697 |
| Opus 5 | $0.00013 | $0.00349 |
| Sonnet 5 | $0.00005 | $0.00139 |
| Haiku 4.5 | $0.00003 | $0.00070 |
Grade A, and why
recurrent-payment 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 4d 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 — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/recurrent-payment — Автоплатежи и карты
Алгоритм — первичная привязка карты
add_customer(customer_key — ваш уникальный ID покупателя, email, phone) — зарегистрируй покупателя.init_payment(amount в рублях, order_id, description, customer_key, recurrent: "Y", success_url, fail_url, notification_url) — первый платёж обязан идти с признаком recurrent, иначе карта не привяжется и автосписаний не будет.- Отдай покупателю PaymentURL из ответа, дождись оплаты, проверь
get_payment_state(payment_id). - RebillId приходит в уведомлении на notification_url. Это ключ карты для последующих списаний — сохрани его на своей стороне.
Алгоритм — списание по подписке
get_card_list(customer_key) — привязанные карты покупателя, маскированные номера и CardId.charge_payment(payment_id — исходный платёж с recurrent, rebill_id — карта, amount) — автосписание. Форма оплаты покупателю не показывается.get_payment_state(payment_id) — подтверди успех, не считай платёж прошедшим по факту вызова.- Чек по факту оказания услуги —
send_closing_receipt(payment_id, email, phone, taxation, items).
Отвязка и удаление
remove_card(customer_key, card_id) — снять одну карту, CardId берётся изget_card_list.remove_customer(customer_key) — удалить покупателя вместе со всеми его картами. Действие необратимое, подтверждай отдельно.- Проверить, заведён ли покупатель, —
get_customer(customer_key).
Важно
- Списание без согласия держателя карты — прямой путь к чарджбэку. Автосписание запускать только по правилу, которое пользователь подтвердил (сумма, периодичность, за что).
- Забыли recurrent: "Y" в первом платеже — RebillId не появится; лечится только новым первичным платежом, задним числом карту не привязать.
- customer_key — ваш идентификатор, а не выданный банком; он же связывает карты с покупателем.

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.

recurrent-payment is a skill published in the GitHub repository theYahia/WWmcp (29 stars, last pushed 2d ago), licensed MIT. It adds 26 tokens to every session and 697 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings.
