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

claude-code-secrets-guard CLAUDE.md 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 5d 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.

What it actually says

secrets-guard (страж секретов)

Наш «проект №0» — разминочная утилита. Контекст для будущих сессий в этой папке.

Что это

PreToolUse-хук для Claude Code, который блокирует публикацию/вывод секретов (пароли, токены, API-ключи, .env, ключи) в Bash-командах.

Цель

Технический барьер к правилу «Безопасность секретов» (см. корневой CLAUDE.md). Критерий «готово»: установлен, test.sh проходит без провалов, срабатывает вживую.

Стек / инструменты

Чистый bash + jq (разбор JSON хука). Никаких внешних зависимостей и сети — важно для доступности из РФ и простоты.

Важные решения

  • Логика вынесена в отдельный скрипт (а не строкой в settings.json) — чище и тестируемо.
  • Активная копия живёт в ~/.claude/hooks/ (глобально, вне sz), чтобы барьер работал в любой папке и любой сессии. Исходник-источник — здесь, в проекте; разворачивается через install.sh.
  • Настройки в отдельном secrets-guard.config; install.sh не перезатирает уже существующий конфиг.
  • Три уровня решения: deny (явная утечка) / ask (риск) / allow (молча пропустить).

Статус

Готово и развёрнуто. Барьер активен. Тест: 27 проверок.

Дальше (TODO, по желанию)

  • Дорастить шаблоны под реальные сервисы СТВ (когда появятся токены/ключи).
  • Подумать про аналогичную проверку для инструментов Write/Edit (не только Bash).
  • Если понадобится серьёзная защита репозитория — подключить gitleaks/pre-commit.

Заметки для Claude

  • Не выводить и не пересылать секреты при работе над проектом (рекурсивно — то же правило).
  • Менять логику — в src/, потом bash src/install.sh для синхронизации с ~/.claude/hooks/, затем bash src/test.sh.
  • Связано с памятью: secrets-policy, backup-setup.
Changes

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.
