platform: Instructions file for Codex

AGENTS.md

platform AGENTS.md is an instructions file for Codex, OpenCode from doka-guide/platform. It costs 2,994 tokens per session, scanned A, original, MIT.

A Russian-language instruction file for the Doka documentation platform. It sets rules for cautious changes, simple implementations, and checking assumptions before coding.

In plain words
What is it for?
It guides work on Doka features and fixes by encouraging minimal code, explicit assumptions, surgical edits, and requests for clarification when requirements are unclear.
Why use it?
It helps agents avoid overengineering, unrequested changes, silent assumptions, and edits that could disrupt nearby documentation-platform code.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions AGENTS.md.

This is doka-guide/platform's own configuration. It tells Codex and OpenCode how to work on platform 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 platform 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

platform 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 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.

AGENTS.md — как работать с платформой Доки

Инструкция для ИИ-агентов: Codex, Cursor, Copilot, Gemini CLI читают этот файл напрямую, Claude Code — через CLAUDE.md, который на него ссылается. Здесь только то, что нужно, чтобы начать работать и не сломать ничего по дороге. Подробное устройство сборки — в docs/how-its-work.md.


1. Правила работы

Правила смещают баланс в сторону осторожности, а не скорости. На мелких задачах включайте здравый смысл.

Сначала подумай, потом пиши

  • Назови свои допущения вслух. Если не уверен — спроси.
  • Если задачу можно понять двумя способами — покажи оба, не выбирай молча.
  • Если есть решение проще — скажи об этом. Возражать можно и нужно.
  • Если что-то непонятно — остановись и назови, что именно непонятно.

Минимум кода

  • Ничего сверх того, о чём попросили.
  • Никаких абстракций ради одного вызова.
  • Никакой «гибкости» и «настраиваемости», которую не заказывали.
  • Никакой обработки ошибок для невозможных ситуаций.
  • Если получилось 200 строк там, где хватило бы 50, — перепиши.

Проверка: сказал бы опытный разработчик, что здесь переусложнено? Если да — упрощай.

Правки хирургические

  • Не «улучшай» соседний код, комментарии и форматирование заодно.
  • Не рефактори то, что не сломано.
  • Держись существующего стиля, даже если сам написал бы иначе.
  • Заметил не связанный с задачей мёртвый код — скажи о нём, но не удаляй.
  • Убирай за собой только то, что осиротело из-за твоих же правок.

Проверка: каждая изменённая строка должна прослеживаться до запроса пользователя.

Цель должна быть проверяемой

Формулируй задачу так, чтобы результат можно было проверить командой:

  • «добавь валидацию» → «напиши тест на неверный ввод, потом сделай, чтобы он проходил»;
  • «почини баг» → «напиши тест, который его воспроизводит, потом сделай, чтобы он проходил»;
  • «отрефактори X» → «убедись, что тесты зелёные до и после».

В многошаговой задаче у каждого шага должна быть своя проверка.

Тест обязателен

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.
