Token cost

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.

Security

Grade A, and why

tbank-messenger 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 — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Чаты и поддержка

Сообщения читает и пишет живой оператор поддержки (или бот банка). Отправка необратима: отозвать нельзя.

Инструменты

Тул Что делает Необратимо
messenger_unread() Сколько непрочитано и в каких чатах — по названиям нет
messenger_conversations(archived, offset) Страница чатов: название, conversationId, непрочитанные, последняя реплика; offset следующей страницы — в шапке нет
messenger_messages(conversation_id, limit, offset, max_chars, before_id) История переписки, старые сверху; по умолчанию последние 20 с текущей страницы банка; before_id листает глубже — на предыдущую страницу нет
messenger_file(conversation_id, file_id, save_to, overwrite) Скачать вложение на диск и вернуть путь: выписка, отчёт, справка нет
messenger_send(conversation_id, text) Отправить сообщение ДА

Порядок

  1. messenger_unread() — если вопрос «есть ли что-то новое», этого часто достаточно: тул сразу называет чаты, а не сырые id.
  2. messenger_conversations() — взять conversationId нужного чата. Поддержка обычно называется «Поддержка». Нет нужного чата — листай: offset из шапки.
  3. messenger_messages(conversation_id) — прочитать. Старые сверху, по умолчанию последние 20 с ОДНОЙ страницы банка: limit=0 — вся страница, offset — окно старее внутри неё (число подскажет шапка). Длинное сообщение по умолчанию обрезано до 400 символов с пометкой — max_chars=0 покажет его целиком. limit/offset листают ТОЛЬКО эту страницу; на предыдущую страницу банка (ещё старее) переводит before_id — id самого старого сообщения, СТАРЕЕ которого догрузить. Дошёл до края и хочешь глубже — тул сам печатает нужный before_id="…": это курсор на следующую страницу, а НЕ «старее ничего нет». Вызови messenger_messages(conversation_id, before_id="<тот id>").
  4. messenger_send(conversation_id, text) — только после того, как показал пользователю текст и получил согласие.

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.
