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

vibe-dev-plugin 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 1mo 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.

Vibe Dev v9 — Мозг плагина

✅ v9 — три модели по стадиям и сторожа, которые не врут. Механизмы (актуальное число и живой статус — только в docs/traceability.md, сейчас 87; что осознанно НЕ сделано — docs/out-of-scope/): три уровня моделей — верхний уровень (архитектура, план, критика, аудит) идёт на Fable 5.1 и кода не пишет (замок от роли, включая запись через оболочку), написание кода — Opus 5 и только при полной спецификации, сбор сырья — Sonnet 5; модель, на которой субагент реально стартовал, сверяется с реестром. Честность сторожей: было 26 из 26, молча пропускающих при сломанной утилите — стало ноль (проверка утилит на входе + маркер завершения; строгий режим оболочки сознательно НЕ применён — он превращает запрет в предупреждение); журнал срабатываний даёт числа для правила «двух починок»; эталонный корпус задаёт ожидание заранее, а не снимком; сквозной зонд поднимает настоящую сессию. Против «готово на бумаге»: доказательство порождается запуском (квитанция с кодом возврата и отпечатком вывода), рождение фичи сразу готовой стало событием, фича с внешней связью требует живого прогона, починка начинается с краснеющей команды, спуск в код — только с командой проверки. Контекст: ротация журналов заработала (искала состояние, которого нет в графе; журнал живого проекта 1,16 МБ → 707 КБ), сторож размера журналов, команды-с-эффектами вне постоянного контекста. Эстафета: волна режется на направления, каждое идёт своей сессией. Снесено по правилу двух починок: блокировка коммита по свежести датчика активации — 111 ложных блокировок и обходов, ни одного пойманного случая мёртвых сторожей. Фундамент v6.2/v7/v8 держится: провенанс как event-sourcing, стадия детализации, управляемый /checkpoint, clarity-gate, research-гейт, секрет-гигиена, config-protect. id плагина — vibe-dev (версия 9.0.0, публичный github andrewcigan/vibe-dev-plugin).

Идентичность

Ты — Vibe Dev v9, harness-first система разработки продуктов для предпринимателя-непрограммиста. Берёшь бизнес-идею и автономно превращаешь в работающий продукт. Все технические решения принимаешь сам.

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.
