A skill for writing and organizing OneScript code, where OneScript is a cross-platform scripting language related to 1C but usable without the 1C platform. It covers .os files, project structure, and package files.

Use it to create or maintain .os files, structure OneScript projects, and work with packagedef, opm, and related directives.

It gives OneScript projects consistent code structure and guidance for the language's syntax and conventions.

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.

Model	Per session	Once invoked
Fable 5	$0.00045	$0.01348
Opus 5	$0.00023	$0.00674
Sonnet 5	$0.00009	$0.00270
Haiku 4.5	$0.00005	$0.00135

Security

Grade A, and why

onescript 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 yesterday.

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 — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.

OneScript

Навык для написания и структурирования кода на OneScript — кроссплатформенном интерпретаторе языка 1С:Предприятие 8 без платформы 1С. Код выполняется из текстовых файлов .os, аналогично Python или Node.js.

Структура модуля

Модуль — текстовый файл с расширением .os. Три секции (сверху вниз):

Секция переменных — Перем ИмяПеременной;
Секция методов — процедуры и функции
Секция тела модуля — код, выполняемый при запуске (обязательно внизу файла)

Минимальный скрипт:

Сообщить("Привет, Мир!");

Процедуры и функции:

Процедура МояПроцедура(Параметр1, Параметр2)
    // операторы
КонецПроцедуры

Функция МояФункция(Параметр1, Параметр2)
    Возврат Параметр1 + Параметр2;
КонецФункции

Типы и литералы

Типизация динамическая. Примитивы: Строка, Число, Булево, Дата; специальные: Неопределено, Null.

Число: 12345.899
Строка: "Текст", кавычка внутри — "". Многострочная: новая строка начинается с |, пробелы до | отбрасываются.
Дата: '20250212235959' или '2025-02-12 23:59:59'

Структура проекта

Рекомендуемая структура каталогов:

src/ — исходный код (в дистрибутив)
src/Классы/ — файлы .os, подключаемые как классы (создание через Новый)
src/Модули/ — файлы .os, подключаемые как общие модули
tests/ — тесты
tasks/ — служебные скрипты (сборка, тесты)
Корень: packagedef (манифест), README, LICENSE

Точка входа (например src/main.os) должна импортировать свой каталог:

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.

onescript is a skill published in the GitHub repository yellow-hammer/skills-onescript (40 stars, last pushed 5mo ago), licensed MIT. It adds 45 tokens to every session and 1,348 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
