A OneScript library for building command-line programs with commands, subcommands, arguments, and options. Commands are defined on classes using annotations.

Use it to create OneScript terminal tools, define their command hierarchy, accept values and options, and show command descriptions.

It provides a structured way to describe command-line input and connect each command to the code that runs it.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 5.1	$0.00046	$0.01922
Opus 5.5	$0.00018	$0.00769
Sonnet 5.5	$0.00009	$0.00384
Haiku 4.5	$0.00005	$0.00192

Measured 1mo ago against content hash d1fde3f6185e, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

autumn-cli 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.

How it starts

The opening of the file, as written. The whole thing — 165 lines — stays where its author put it; the contents beside it link to each section on GitHub.

autumn-cli

Обёртка над библиотекой cli для создания консольных приложений на фреймворке Autumn. Команды, подкоманды, аргументы и опции описываются аннотациями на классах.

Сверено с autumn-cli 1.3.0 на autumn 5.0.2: зависимость пакета — autumn от 4.3.7, верхней границы нет. Отдельного релиза под пятёрку нет, и этот тег на 5.0.2 работает. Точка входа ниже не вызывает методы Поделка, которые в пятёрке удалены. Примеры самого релиза (example/main.os) их ещё содержат: в новый код их не копируй.

Подключение и запуск

Точка входа (например main.os):

#Использовать autumn
#Использовать autumn-cli
#Использовать "Каталог/С/Классами/Команд"

Поделка = Новый Поделка();
Поделка.ЗапуститьПриложение();

Каталог с командами должен содержать классы с аннотацией &КомандаПриложения или &ПодкомандаПриложения. Библиотека сама ставит рогатку ИКС_Рогатка с ЗапускатьВФоне = Ложь: команда выполняется в текущем потоке, затем процесс завершается. Вторую рогатку на те же аргументы командной строки не вешай.

Команда приложения

Класс объявляется командой аннотацией на конструкторе. Метод, выполняемый при вызове команды, помечается &ВыполнениеКоманды.

&Аргумент(Имя = "ARG", Описание = "Значение числа")
&ТЧисло
Перем ПереданноеЧисло;

&КомандаПриложения(Имя = "p plus", Описание = "Прибавляет 10 к заданному числу")
Процедура ПриСозданииОбъекта()
КонецПроцедуры

&ВыполнениеКоманды
Процедура ВывестиРезультатСложения() Экспорт
    Результат = ПереданноеЧисло + 10;
    Сообщить("Результат сложения: " + Результат);
КонецПроцедуры

Параметры аннотации &КомандаПриложения: Имя — имя в CLI (например "p plus"), Описание — текст справки. Повторяемый параметр Подкоманда устарел: подкоманду привязывай параметром Родитель с её стороны.

Аргументы и опции

Аргумент — позиционный аргумент: переменная с &Аргумент(Имя = "ARG", Описание = "...").
Опция — именованный параметр: переменная с &Опция(Имя = "n name", Описание = "Имя пользователя").

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.
