+BigBlueButton is deployed for workshops and webinars:
+- Multi-container setup with separate services (HTML5, Freeswitch, Kurento, etc.)
+- GraphQL API for real-time data
+- Integration with Odoo via `bbb_connector` addon
+- Webhooks for meeting events

+## 🚨 КРИТИЧЕСКИ ВАЖНО: Выбор модели
+
+**ВСЕГДА используй Haiku (`model: "haiku"`) для:**
+- ✅ Работы в терминале (Bash, ssh команды)
+- ✅ Чтения и редактирования файлов (Read, Edit, Write)
+- ✅ Поиска в коде (Grep, Glob)
+- ✅ Работы с Docker/Git
+- ✅ Отладки и исправления ошибок
+- ✅ Любых практических задач по коддингу
+
+**Используй Sonnet ТОЛЬКО для:**
+- 📊 Сложного планирования архитектуры
+- 📋 Анализа требований пользователя
+- 🎯 Принятия стратегических решений
+- 🔍 Глубокого анализа проблем
+
+**Примеры:**
