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

tax-prep 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.

Подготовка к налогам (быстрый запуск)

Перед налоговым сроком вопрос один: сколько отложить и что собрать, чтобы не ловить пени и не дёргать бухгалтера в последний день. Эта команда сразу, без лишних вопросов, считает аванс по УСН (или собирает выплаты подрядчикам / взносы ИП) и отдаёт готовый пакет бухгалтеру.

Запусти налоговый workflow через скилл tax-season-organizer. Действуй сразу — пользователь набрал /tax-prep, фазу discovery пропускаем.

Разбери аргументы:

  • --mode (по умолчанию выводится из даты — 1–3 кв. → авансы-усн, конец года / декабрь → оба) — авансы-усн для расчёта авансового платежа по УСН, подрядчики-гпх для учёта выплат подрядчикам и самозанятым, взносы-ип для расчёта страховых взносов ИП «за себя», оба для комбинированного прогона (авансы + подрядчики).
  • --year (по умолчанию — текущий год)

Рамка: Открывай каждый результат строкой «Подготовлено для проверки вашим бухгалтером. Не является налоговой консультацией.»

Шаг 1 — Определи режим

Если --mode не передан:

  1. Проверь текущую дату. Октябрь–январь → по умолчанию оба. Иначе → авансы-усн.
  2. Подтверди у собственника: «Судя по времени года, подготовлю [режим]. Сделать что-то другое?»

Шаг 2 — Авансовый платёж по УСН (если режим включает авансы-усн)

  1. Подтяни ОПиУ нарастающим итогом с начала года по последний завершённый квартал из ~~бухгалтерии (например, 1С:Бухгалтерия или МойСклад).
  2. Если коннектор ~~бухгалтерии не подключён — попроси выгрузить ОПиУ в CSV или вставить ключевые числа (доходы, расходы) вручную.
  3. Уточни объект налогообложения: «Доходы» (6%) или «Доходы минус расходы» (15%). Если не знаешь — спроси, это меняет всю логику.
  4. Спроси: «Сколько авансов по УСН вы уже заплатили в этом году?»
  5. Рассчитай: налоговую базу нарастающим итогом, налог по ставке объекта, для «Д−Р» — проверку минимального налога 1% от доходов, авансовый платёж к доплате за текущий квартал.
  6. Явно назови каждое допущение — ставку (регион мог снизить), объект, страховые взносы к зачёту.
  7. Выдай оформленный расчёт со сроком уплаты текущего квартала.

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.
