geo

geo is a skill for Claude Code from tonydzi/second-brain-starter-kit. It costs 74 tokens per session (2,067 once invoked), scanned A, original, MIT.

A measurement guide for checking whether AI search engines can find, index, and cite your site. It treats crawling, appearing in a search index, and being named in an AI answer as separate stages.

In plain words
What is it for?
Use it to measure your site's visibility in AI engines and decide which discovery problem needs attention first.
Why use it?
It prevents you from mistaking crawler visits for real visibility. This helps show whether the problem is access, search indexing, or citation before creating more content.

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

geo 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 21d 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.

/geo — замер находимости в AI-движках

Боль, из-за которой скилл существует. 04.08.2026 мы чуть не «отмасштабировали» уже решённую стадию. Логи показали 13 845 обращений краулеров за 9 дней — выглядело как успех. Замер показал: страниц в индексе Bing/DDG ноль, а Gemini на прямой вопрос про наш домен отвечает «no verifiable independent lab operating under that name». Без замера мы бы потратили недели на красивые страницы, которых никто не увидит.

Три стадии — не одна

КРАУЛ  ──►  ИНДЕКС  ──►  ЦИТАТА
робот      страница      движок называет
пришёл     в выдаче      нас в ответе

Стадии проваливаются независимо, и лечатся РАЗНЫМ:

Провалена стадия Симптом Лечение НЕ лечится
Краул ботов в логах нет robots, sitemap, статика без JS, llms.txt контентом
Индекс боты ходят, в выдаче нас нет ссылочная масса, возраст, различимое имя ещё одной страницей
Цитата в выдаче есть, в ответах нет атрибутируемый формат, CITATION.cff, присутствие в курируемых списках рекламой

Замер 04.08: краул ✅ · индекс ❌ · цитата ❌.

Наше преимущество — мы владеем origin

Почти никто не знает, какие его страницы AI-краулеры перечитывают, а какие взяли один раз и забыли. Мы владеем origin, значит видим логи, значит считаем частоту возврата по каждому URL. Это превращает GEO из гадания в цикл.

Как запускать

python ~/.claude/scripts/geo_measure.py --all --verbose
  • --crawl — кто из движков ходил, на какие URL, как часто возвращается
  • --index — есть ли мы в выдаче (сперва контроль прибора, см. ниже)
  • --format — готовность артефактов к цитированию (зовёт publish_format_gate.py)
  • --html PATH — дашборд ([[prefer-visual-dashboards]])
  • --selftest — доказать, что парсер умеет краснеть

Коды: 0 картина снята · 1 есть красное · 4 прибор не смог измерить.

⚠️ Железный контракт: ноль — вердикт только после контроля

Скрипт СНАЧАЛА ищет чужую фразу, про которую доказано, что она в индексе есть. Контроль не нашёлся → скрипт печатает «прибор не отвечает» и выходит 4, не показав наших цифр. Потому что «0 результатов» одинаково выглядит и когда нас нет в индексе, и когда сломалась качалка.

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.
