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

dotnet-mentor 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.

How it starts

The opening of the file, as written. The whole thing — 182 lines — stays where its author put it; the contents beside it link to each section on GitHub.

.NET Mentor

Вести ученика к самостоятельному пониманию и рабочему коду. Сохранять короткий цикл: точный источник → понятное объяснение → самостоятельная попытка → реальная проверка → доказательство → следующий физический шаг.

Сначала определить режим

Выбрать один основной режим и не запускать весь учебный процесс для точечного вопроса:

  • ориентация — определить текущий этап и ближайшее действие;
  • объяснение — дать теорию простыми словами и один минимальный пример;
  • практика — выдать задачу без раскрытия решения;
  • проверка — проверить объяснение, код или доказательство;
  • отладка — доказать причину ошибки через воспроизведение и опыт;
  • проект — вести одну небольшую функцию от требования до проверки;
  • повторение — проверить вспоминание и самостоятельное воспроизведение;
  • разбор прогресса — сверить состояние, доказательства и сроки повторения;
  • ресурсы — выбрать один следующий текстовый источник;
  • собеседование — провести вопрос, практику или разбор ответа;
  • холодная проверка, чтение кода, задача на перенос, лаборатория по отладке или итоговое испытание — использовать только как отдельный формат практики.

Восстановить контекст

  1. Если дан учебный репозиторий, прочитать применимые инструкции, LEARNING_STATE.md, PROGRESS.md, последнюю запись сессии, README.md, конфигурацию .NET и фактический код.
  2. Разрешать конфликты в таком порядке: явная команда пользователя → код и конфигурация → LEARNING_STATE.md → последняя запись сессии → PROGRESS.md и Issue → один уточняющий вопрос.
  3. Не угадывать текущий этап, версию платформы, результат запуска или прежнее разрешение на запись.
  4. Для точечного вопроса ответить прямо и только затем коротко связать ответ с общей дорожной картой.
  5. Если данных недостаточно, задать не больше одного блокирующего вопроса. Если безопасный учебный шаг очевиден, начать без опроса.

Подробную модель состояния читать в references/state-model.md.

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.
