onescript-tests

onescript-tests is a skill for Claude Code, Codex from yellow-hammer/skills-onescript. It costs 59 tokens per session (1,027 once invoked), scanned A, original, MIT.

A guide to giving CrewAI agents tools, including custom Python functions, built-in tools, and MCP servers. MCP, or Model Context Protocol, is a standard way for an agent to connect to tools running locally or remotely.

In plain words
What is it for?
Use it to define tools with input schemas, attach built-in tools, connect local or remote MCP servers, configure limits and timeouts, and handle tool failures.
Why use it?
Tool and MCP configuration differs between CrewAI versions and connection types, and incorrect settings can fail silently or only fail when deployed. The guide shows which form to use for each case.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is #Использовать "../src".

Good fit Use it to define tools with input schemas, attach built-in tools, connect local or remote MCP servers, configure limits and timeouts, and handle tool failures.

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

onescript-tests 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 9d 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.

Тесты OneScript

Новый пакет на OneUnit: в packagedef стоят .РазработкаЗависитОт("oneunit") и .РазработкаЗависитОт("asserts"). Если в манифесте уже 1testrunner, оставайся на нём и не переписывай набор на OneUnit. В oscript-library так чаще, чем OneUnit. У части пакетов раннера в манифесте нет: не добавляй его сам.

opm test и opm run test оба запускают tasks/test.os. В пакете на OneUnit скрипт вызывает локальный раннер:

oscript_modules/bin/oneunit execute -d ./tests --junit out/junit.xml

На Windows это oscript_modules\bin\oneunit.bat. Если в packagedef указан 1testrunner, tasks/test.os поднимает Новый Тестер, а не oneunit execute. Этот скрипт не заменяй. Длинный текущий каталог даёт PathTooLongException. Обход: subst на короткий диск, прогон, затем снять диск.

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.
