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 | $0.00020 | $0.00597 |
| Opus 5 | $0.00010 | $0.00298 |
| Sonnet 5 | $0.00004 | $0.00119 |
| Haiku 4.5 | $0.00002 | $0.00060 |
Grade A, and why
refund-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.
What it actually says
/refund-payment — Возврат и отмена
Алгоритм
get_payment_state(payment_id) — текущий статус платежа. Без этого шага не действовать: от статуса зависит, какой инструмент нужен.- Выбери операцию по статусу:
- деньги уже списаны (платёж завершён) →
refund_payment(payment_id, amount); - средства только захолдированы двухстадийным платежом, списания не было →
cancel_payment(payment_id, amount); - нужно, наоборот, дозавершить холд →
confirm_payment(payment_id, amount).
- деньги уже списаны (платёж завершён) →
- Сумма не указана — возврат полный. Указана меньшая — частичный возврат; сумма всегда в рублях.
- Покажи пользователю, что именно вернётся и с какого платежа, и дождись подтверждения. Возврат необратим.
- Выполни операцию и перечитай
get_payment_state— покажи новый статус. - Если по платежу пробивался чек, отправь закрывающий:
send_closing_receipt(payment_id, email, phone, taxation, items — позиции с Name, Price, Quantity, Amount, Tax).
Важно
refund_paymentиcancel_payment— разные операции, а не синонимы: возврат идёт после списания, отмена — до него. Ошибка выбора даёт отказ банка, а не молчаливый успех.- Частичный возврат можно повторять до исчерпания суммы платежа; складывай уже возвращённое, прежде чем назвать доступный остаток.
- Ставка НДС в позициях чека (Tax) обязана совпадать с исходным чеком продажи, иначе ФНС отклонит.

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.
