1c-dev

1c-dev is a skill for Claude Code from vgtitov/bsl-ai-toolkit. It costs 524 tokens per session (3,093 once invoked), scanned A, original, MIT.

A development and code-review aid for 1C:Enterprise 8.3, a business software platform, using its BSL programming language. It checks real project code through MCP tools and uses the platform’s documentation instead of relying on memory.

In plain words
What is it for?
Use it to write, change, or review BSL code, shared modules, forms, queries, data registers, roles, and features described in technical specifications.
Why use it?
It reduces errors caused by guessing how a particular 1C configuration works. It also checks edited code for syntax, coding standards, and database access inside loops.

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

1c-dev 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 7d 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.

Разработка 1С (BSL) — писать корректный и производительный код по реальному коду

Локализация (сначала, если есть)

Если в скилле есть каталог references/local/ — прочитай его ПЕРЕД работой: version-stack.md (версии платформы/библиотек, режим совместимости, префиксы ТВОЕЙ компании) и остальные карты. При противоречии локальное побеждает generic. Контракт — docs/SKILL_LOCALIZATION.md toolkit.

Скилл разработчика: писать prod-ready BSL и ревьюить его по реальному коду и стандартам, не по памяти. Адаптируется под любую конфигурацию/расширение — заполни конвенции своего проекта (см. ниже).

Главное правило: спроси инструмент, не угадывай

Нейросеть врёт в деталях 1С. Источник истины — реальный код и официальная справка:

  • Перед написанием — найди, как уже сделано: MCP-поиск по коду (find/search/read), затем grep по клонам. Сигнатуры встроенных функций — справка платформы (MCP справки платформы под твою версию).
  • После правки — прогони BSL Language Server (синтаксис + стандарты ИТС). До 3 циклов автоисправления.
  • Гвард производительности (ENFORCED) — прогони детектор «обращение к БД в цикле»: python scripts/bsl_guard.py <изменённые .bsl> (exit 1 = находки). Ловит Запрос…Выполнить()/.ПолучитьОбъект()/ .Ссылка.<Реквизит> внутри Пока/Для (баг печатной формы). То же на коммите — pre-commit хук на staged *.bsl.
  • Нет поведения ни в коде, ни в справке — так и скажи. Механизм без сверки помечай [проверить], не «верно».

Алгоритм поиска (MCP-first): find_object → search → read_module → grep по клонам. Параметром scope ограничивай слой/контур или расширяй на все (scope задаётся в config/layers.*.toml; без конфига — все слои). Не делай вывод об отсутствии по непросмотренному слою.

Когда файл уже найден и вопрос точечный (что вызывает эту функцию, где она объявлена, какой тип у выражения, не сломает ли правку сигнатуры другой контекст вызова) — не гадай по тексту и не грепай заново: bsl-ls-native (MCP ≥1.0, JDK 21+) даёт definition/find_references/call_hierarchy/hover/type_at_position семантически, без ложных совпадений по имени. Справка по глобальным функциям/типам платформы (сигнатуры, since/deprecated, примеры) — тем же MCP: global_member_info/global_member_search/type_info.

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.
