cross-source-verify is a skill for Claude Code from ilyautov/small-business-ru. It costs 199 tokens per session (2,618 once invoked), scanned A, original, Apache-2.0.

A cross-checking tool that combines results from multiple sources, removes duplicates, scores confidence, and shows where sources agree or disagree.

In plain words
What is it for?
Use it to verify company or other factual information across aggregators, government registers, websites, and data exports, then produce one answer with confidence levels and visible conflicts.
Why use it?
It reduces the risk of trusting one inaccurate source or treating conflicting figures as equally reliable. You can see the evidence behind the final answer instead of having one version chosen silently.

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

cross-source-verify 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 9d 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.

Cross-Source Verify — движок круговой сверки

Последняя миля любой проверки: сырые результаты из N источников → один связный ответ, которому можно доверять, с явной оценкой уверенности и показанными расхождениями.

Один источник звучит уверенно и часто врёт. Агрегатор отдаёт ровную карточку с точными числами — и ты веришь, потому что цифра конкретная. Но конкретная ≠ верная: у соседнего агрегатора по той же компании число другое, а ты этого не видишь, пока не откроешь оба. Этот движок открывает все сразу и сводит — не выбирая молча одну версию, а показывая, где источники согласны (это и есть факт), а где разошлись (это флаг).

Принцип (POV), доказан вживую 15.06.2026. Прогнали одну компанию через 5 агрегаторов: число судов разошлось почти втрое (примерно ~500 / ~1000 / ~1500 — разная методология), при этом выручка и ФССП совпали у всех. Вывод движка: один источник = единая точка отказа и ложная точность. Факт = совпадение у ≥3; расхождение = разброс, а не выбор одной цифры. Совпало → уверенность; разошлось → флаг. (Цифры округлены; проверяйте сами.)

Шкала авторитетности источников (РФ)

Уровень Источники Вес
Highest — первоисточник Госреестры: ЕГРЮЛ/ЕГРИП ФНС, ГИР БО, kad.arbitr, ФССП, ЕФРСБ/Федресурс, нормативка (НК/ГК/ТК), официальная документация максимальный
High — официальная сводка Прозрачный бизнес ФНС, реестры ЦБ/Роскомнадзора, рецензируемые статьи, первичная отчётность высокий
Moderate — агрегатор (проверенный) checko, rusprofile, saby/СБИС, audit-it — собирают из официальных, но добавляют свою методологию/скоринг средний, кросс-сверять
Low-moderate — агрегатор (шумный) list-org (подмешивает чужие сигналы), отраслевые порталы, экспертные блоги проверять принадлежность данных
Low — неподтверждённое форумы, отзывы, маркетинг, агрегаторы новостей, соцсети только как гипотеза
Unverified — со слов данные, которые дал пользователь как истину помечать «не верифицировано»

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.
