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

counterparty-guard 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 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/fetch_counterparty.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Counterparty Guard — проверка контрагента по ИНН

Помогает оценить риск работы с контрагентом по открытым данным. Не является юридической или кредитной гарантией. Финальное решение — за собственником.

Отгрузить в долг, внести предоплату, подписать договор на год — и через месяц узнать, что контрагент в банкротстве, а директор дисквалифицирован. Самое обидное: всё это было открыто ещё до сделки — в ЕГРЮЛ, ФССП, картотеке арбитража, ЕФРСБ. Просто никто не свёл это в одну картину за те пять минут, что есть у собственника. Скилл сводит — по одному ИНН, до сделки, в светофор 🟢/🟡/🔴 с рекомендацией («отсрочка / только предоплата / избегать») и списком того, что мониторить дальше.

Почему круговая сверка, а не один агрегатор (живой тест 15.06.2026). Прогнали одну компанию через 5 бесплатных агрегаторов. Число судов разошлось почти втрое: у одного примерно ~500, у другого ~1000, у третьего ~1500 (разная методология подсчёта дел/эпизодов), а один вдобавок подмешал чужие банкротные «намерения». Зато выручка и число исполнительных производств совпали у всех. Отсюда главный принцип скилла: одиночному агрегатору верить нельзя — счётчики врут уверенно. Факт = то, что совпало у ≥3 источников; расхождение = флаг, а не повод выбрать одну цифру. (Цифры намеренно округлены; проверяйте на своих контрагентах сами.)

Принцип (POV). Риск контрагента — это не «есть компромат / нет компромата», а сведение противоречивых открытых сигналов в одно датированное решение. Деньги реальные, поэтому: считаем кодом, датируем каждый сигнал, светофор двигаем только вверх по тревожности (вниз — лишь при опровержении сигнала, не «потому что хочется сделки»), одиночному источнику не верим. Скилл не выносит приговор компании — показывает риск собственнику и оставляет решение ему.

Цель: по ИНН собрать открытые данные и выдать светофор риска с понятной рекомендацией — работать ли с контрагентом и на каких условиях (предоплата / отсрочка / избегать). Работает в два захода: быстрый quick-scan по deal-killer-сигналам, затем полное досье по запросу.

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.
