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.

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 | $0.00018 | $0.03209 |
| Opus 5 | $0.00009 | $0.01605 |
| Sonnet 5 | $0.00004 | $0.00642 |
| Haiku 4.5 | $0.00002 | $0.00321 |
Grade A, and why
model-selection 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 3d 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.

Стратегия выбора моделей
Распределение моделей по ролям.
Применяется: при работе с AI-ассистентами (Claude Code, Cursor, другие IDE).
Принцип
Opus - основная рабочая модель оркестратора. Кросс-ревью - внешние модели (Codex gpt-5.6-sol / Cursor Grok), Sonnet отключен. Субагенты-исполнители - по типу их работы (Haiku / Sonnet / Opus).
Основная сессия (оркестратор - тот, кто держит замысел и принимает решения): анализ, кодогенерация, рассуждение, рефакторинг - Opus. Кросс-ревью (план, код) с 2026-07-15 делают внешние модели через подписки, экономя Claude-токены: основной ревьюер - Codex gpt-5.6-sol (нативный codex review), опционально Grok через Cursor; Sonnet из ревью отключен (детали и fallback - в промптах кросс-ревью). Субагентам, которым делегируется ИЗОЛИРОВАННАЯ работа (разведка, механическая выборка, отдельный анализ), модель подбирается по типу задачи - от Haiku на механике до Opus на тяжелом анализе (см. "Модель субагента по типу задачи").
Третий уровень - Fable 5 (claude-fable-5) точечно поверх Opus на long-horizon автономных прогонах и самых тяжелых задачах (см. раздел ниже). Не дефолт: дороже Opus вдвое и быстрее расходует недельную квоту, включается под конкретный заход через /model.
Распределение
Opus - все задачи
| Категория | Примеры |
|---|---|
| Архитектура | Проектирование, выбор технологий, breaking changes, миграция |
| Безопасность | Ревью кода, аудит RLS, поиск уязвимостей |
| Production-баги | Порча данных, race conditions, регрессии |
| Кодогенерация | Формы, тесты, запросы, скрипты, конфигурации |
| Рефакторинг | Упрощение, извлечение методов, консолидация |
| Исследование | Навигация по коду, поиск, документация |
| Итеративная работа | Баг-фиксы, реализация фич, тестирование |
Кросс-ревью - внешние модели (Codex / Grok), не Sonnet
| Когда | Кто ревьюит |
|---|---|
| После завершения кода | Codex gpt-5.6-sol (codex review, сам читает git diff) + опц. Grok через Cursor |
| После составления плана | Codex gpt-5.6-sol (нативный codex review) + опц. Grok |
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.

model-selection is a cursor rule published in the GitHub repository Desko77/cursor-1c-skills (53 stars, last pushed 5d ago), licensed MIT. It adds 18 tokens to every session and 3,209 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
