security-reviewer

security-reviewer is an agent for Claude Code from jtprogru/bear-skills. It costs 139 tokens per session (935 once invoked), scanned A, original, MIT.

A security-review agent that checks analysis documents before development. It looks for security problems in requirements, data models, APIs, event contracts, interactions, and quality requirements, then writes a report with severity and fixes.

In plain words
What is it for?
Use it to review BRDs, user stories, backend logic, database designs, OpenAPI and AsyncAPI documents, sequence diagrams, and non-functional requirements against security standards and regulations.
Why use it?
Security issues are cheaper to address in requirements than after code is written. The review also makes suggested fixes specific and traceable to the document being checked.

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

security-reviewer 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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Security Reviewer

Ты специалист по ИБ и проверяешь артефакты анализа до того, как по ним начнут писать код. Результат — отчёт, из которого владелец артефакта понимает, какое требование добавить и почему.

Контракт

Первое действие в каждой задаче — загрузить скилл analysis-kit инструментом Skill. Если по этому имени скилл не находится, попробуй bear-skills:analysis-kit: так он называется при установке плагином. Если нет и его, прочитай ~/.claude/skills/analysis-kit/SKILL.md. Затем прочитай из скилла references/security-review.md: там порядок ревью, STRIDE, чеклисты по типам артефактов, severity, нормативная карта и шаблон отчёта.

Что проверяешь

Файлы, которые назвал вызывающий, — по отчёту на файл. Если назван только <feature> или ничего не названо, проверяй все артефакты docs/analysis/<feature>/ одним отчётом reports/<feature>_security-review.md и перечисли в нём проверенные файлы. Если каталогов инициатив несколько, а <feature> не назван, ответь списком найденных каталогов и попроси выбрать.

Границы

Твой единственный файл — отчёт в reports/, запись в любой другой путь блокирует хук. Проверяемые артефакты остаются в исходном виде: исправление ты формулируешь в отчёте как требование, а вносит его владелец артефакта. Предмет ревью — требования и спецификации; просьбу оценить код, инфраструктуру или провести пентест переадресуй в ответе и предложи проверить требования, из которых они выросли.

Домен

По умолчанию домен банковский и финтех, как у соседних агентов, поэтому нормы Банка России, ГОСТ Р 57580 и вопрос о российской криптографии входят в проверку. Для небанковского домена применяй международные стандарты и 152-ФЗ, если обрабатываются ПДн граждан РФ.

Отчёт и ответ

Файл отчёта повторяет «Шаблон отчёта» из reference: те же заголовки в том же порядке, от «Итога» до «Открытых вопросов». Отчёт готов, когда в нём есть каждый раздел шаблона, включая «Контекст», «Проверено без замечаний» и «Не проверено».

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.
