archgate

archgate is a skill for Claude Code from TserenTserenov/FMT-exocortex-template. It costs 75 tokens per session (7,056 once invoked), scanned A, original, MIT.

An architecture review method that evaluates a proposed system design or technology change across seven qualities.

In plain words
What is it for?
It helps assess proposed architecture, tools, and system changes, including required checks and extension-based review gates.
Why use it?
It provides a structured screening process for finding architectural risks before a design is adopted.

Skill for Claude Code

Written for Claude Code: argument-hint in frontmatter.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is bash .claude/scripts/load-extensions.sh archgate before.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

archgate 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 10d 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.

АрхГейт v3.1 — оценка архитектурного решения

Выполни оценку решения: $ARGUMENTS

When to use

Оценка архитектурного решения по 7 характеристикам ЭМОГССБ (v3.1 — фильтр допуска, атрибут-сценарии, совет затронутых сторон; профиль без агрегатного балла, conjunctive screening). Используй когда пользователь предлагает архитектурное решение, новый инструмент или системное изменение.

Algorithm

Extensions before (БЛОКИРУЮЩЕЕ)

До Шага 0-А ровно один раз за верхнеуровневый вызов загрузить расширения (фаза before обязательна и для быстрого трека — фильтр допуска выполняется только после неё):

bash .claude/scripts/load-extensions.sh archgate before

Код 0 → прочитать каждый путь из вывода в алфавитном порядке и выполнить. Код 1 → расширений нет, продолжить. Любой другой код, ошибка расширения, явный BLOCK/STOP или содержательное возражение рецензента внутри расширения блокирует начало оценки: показать путь файла и наблюдаемую причину.

Каждое before/checks-расширение завершает инструкции явным маркером ARCHGATE_EXTENSION: PASS либо ARCHGATE_EXTENSION: BLOCK — <причина>. Отсутствующий или неизвестный маркер = ошибка блокирующей фазы, не PASS.

Защита от рекурсии: каждая фаза before, checks, after выполняется не более одного раза за верхнеуровневый вызов. Расширению запрещено вызывать /archgate, повторно загружать archgate.* или иначе повторно входить в этот жизненный цикл. Попытка рекурсии считается ошибкой текущей фазы: блокирует before/checks, а в after даёт предупреждение и пропускается.

Расширения — доверенные локальные инструкции, а текстовый детектор — защита от прямой случайной рекурсии, не песочница для враждебного shell-кода. Не исполнять собранную через eval, декодирование, подстановку переменных или конкатенацию команду/инструкцию из расширения: неоднозначную косвенную команду считать той же ошибкой рекурсии (BLOCK в before/checks, WARN и пропуск в after).

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.
