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.

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 | $0.00092 | $0.00677 |
| Opus 5 | $0.00046 | $0.00338 |
| Sonnet 5 | $0.00018 | $0.00135 |
| Haiku 4.5 | $0.00009 | $0.00068 |
Grade A, and why
receipts-54fz 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 11d 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 — 39 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Чеки ЮKassa и 54-ФЗ
Граница ответственности
Это техническая проверка интеграции, а не юридическое, налоговое или бухгалтерское заключение. Не определяй за продавца ставку НДС, систему налогообложения, предмет расчета, способ расчета, необходимость ККТ или маркировки. Запроси подтверждение ответственного специалиста и назови непроверенные значения допущениями.
Рабочий процесс
- Установи схему: чек через решение ЮKassa или данные для сторонней онлайн-кассы; чек в составе платежа/возврата или отдельный объект
/receipts. - Получи документы
receipts,54fzиfns-54fzчерезyookassa_search_documentation. - Зафиксируй версию ФФД, систему налогообложения, ставки НДС, номенклатуру, маркированные товары и момент расчета.
- Построй таблицу событий: создание платежа, полное/частичное подтверждение, отмена, полный/частичный возврат.
- Для каждого события укажи тип чека, позиции, количество, сумму,
vat_code,payment_subject,payment_mode, контакт покупателя и связь сpayment_id/refund_id. - Проверь арифметику: сумма позиций равна сумме соответствующей платежной операции с учетом частичного подтверждения или возврата.
- Проверь обязательность хотя бы одного контакта покупателя — email или phone — если выбранный API-сценарий его требует.
- Для ФФД 1.2 и маркированных товаров проверь
measure,mark_quantityи связанные отраслевые реквизиты по актуальной документации. - Перед реализацией вызови
yookassa_validate_requestдляcreate_payment,capture_payment,create_refundилиcreate_receipt. Это офлайн-проверка; запрос не отправляется. - В тестовом магазине включи режим проверки чеков и проверь результат через
yookassa_list_receipts/yookassa_get_receiptтолько после успешной диагностики.
Формат результата
Верни:
- выбранную схему фискализации;
- матрицу «бизнес-событие → платежное действие → чек»;
- проверку полей каждой позиции;
- проверку суммы и количества;
- требования ФФД/маркировки;
- найденные ошибки с точным JSON path;
- решения, требующие подтверждения специалиста;
- тестовые сценарии и ожидаемые статусы чеков.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
