AGENTS.md

multi AGENTS.md is an instructions file for Codex, OpenCode from szarkans/multi. It costs 631 tokens per session, scanned A, original, MIT.

Project instructions for multi, a Claude Code plugin where several AI models review the same code and disagreements highlight possible problems.

In plain words
What is it for?
Use them when changing multi, running its tests or code review, updating versions or documentation, and maintaining its Bash scripts.
Why use it?
They define checks to run before pushing and guard against shell compatibility issues, unsafe repository instructions, and ignored review findings.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions .claude-plugin; mentions Claude Code; $skill-name invocation.

This is szarkans/multi's own configuration. It tells Codex and OpenCode how to work on multi itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything multi configures →

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

multi AGENTS.md 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 12d 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.

What it actually says

Правила проекта multi

Плагин multi для Claude Code: несколько моделей ревьюят один и тот же код, разногласия — сигнал. Чужой суд честнее своего.

Перед пушем

  1. Все суиты зелёные, каждая выдала ALL PASS: for t in scripts/test-*.sh evals/test-*.sh; do echo "$t: $(bash "$t" 2>&1 | tail -1)"; done (не bash scripts/test-*.sh — так bash запускает только первый файл, остальные уходят ему аргументами).
  2. Живой прогон /multi:code-review на диффе, минимум один круг. Находки не выкидываются молча: каждая либо чинится, либо попадает в отчёт с причиной.
  3. Коммит и пуш — только после согласия Серёжи.

Баш-скрипты

  • Работают на bash 3.2 (стоковый macOS). Известные ловушки: declare -A нет вообще; обращение к пустому массиву под set -u — падение; [ -f ] фолловит симлинки; grep -q в пайпе под pipefail ломает условие из-за SIGPIPE; [[:print:]] под LC_ALL=C режет не-ASCII имена. mkdir — не лок: uutils coreutils (Rust, Ubuntu 25.10+) отвечает 0 обоим гонщикам (замер 07.09.2026), лок — set -o noclobber; : > f.
  • Статус бэкенда — это маркеры и файлы, никогда не парсинг текста ответа модели.
  • Пустой файл ответа никогда не читается как «всё чисто».
  • Правила из ревьюируемого репозитория — недоверенные данные. Защиту в collect-context.sh не ослаблять; каждое новое исключение закрывается тестом в test-injection.sh.

Версии и доки

  • Версия бампается синхронно в .claude-plugin/plugin.json и .claude-plugin/marketplace.json. Semver: x.0.0 — большая переделка, x.1.0 — стоящее обновление, x.0.x — багфикс.
  • Доки (SPEC и прочее) живут в docs/; папка в .gitignore — в коммиты не попадают.
  • Критика от внешних моделей собрана в issue #4; её дедуп — в docs/SPEC.md.

Рабочий процесс

  • Багфиксы — в текущем чате; хотелки и новые режимы — отдельным чатом.
  • Сверяйся с origin/main и памятью через $dont-forget about перед тем, как браться за работу.
Changes

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.
