+# Система постепенного сжатия истории сообщений
+
+## Обзор
+
+Реализована система постепенного сжатия истории сообщений для оптимизации использования памяти и улучшения производительности чат-бота. Система автоматически сжимает старые сообщения, сохраняя при этом важную информацию.
+
+## Основные возможности
+
+### 1. Автоматическое сжатие
+- Сжатие активируется при превышении порогового количества сообщений
+- Старые сообщения группируются и сжимаются в краткие резюме
+- Системные сообщения всегда сохраняются
+- Последние сообщения остаются без изменений
+
+### 2. Умная суммаризация
+- Использование ИИ для создания кратких резюме старых сообщений
+- Раздельная обработка сообщений пользователя и ассистента
+- Сохранение ключевой информации при сжатии
+
+### 3. Настраиваемые параметры
+- `EnableHistoryCompression` - включение/отключение сжатия
+- `CompressionThreshold` - порог активации сжатия (по умолчанию 20 сообщений)
+- `CompressionTarget` - целевое количество сообщений после сжатия (по умолчанию 10)
+- `MinMessageLengthForSummarization` - минимальная длина сообщения для суммаризации (50 символов)
+- `MaxSummarizedMessageLength` - максимальная длина сжатого сообщения (200 символов)
+
+## Архитектура
+
+### Новые компоненты
+
+1. **IHistoryCompressionService** - интерфейс для сжатия истории
+2. **HistoryCompressionService** - реализация сервиса сжатия
+3. **Обновленный ChatSession** - поддержка асинхронного сжатия
+4. **Обновленный AIService** - интеграция сжатия в генерацию ответов
+5. **Обновленный ChatService** - использование сжатия при обработке сообщений
+
+### Алгоритм сжатия
+
+1. **Проверка необходимости сжатия** - сравнение количества сообщений с порогом
+2. **Разделение сообщений** - отделение системных, старых и новых сообщений
+3. **Группировка по ролям** - отдельная обработка сообщений пользователя и ассистента
+4. **Суммаризация** - создание кратких резюме с помощью ИИ
+5. **Объединение** - формирование финального списка сообщений
+
+## Конфигурация
+
+### appsettings.json
+```json
+{
+  "AI": {
+    "EnableHistoryCompression": true,
+    "CompressionThreshold": 20,
+    "CompressionTarget": 10,
+    "MinMessageLengthForSummarization": 50,
+    "MaxSummarizedMessageLength": 200
+  }
+}
+```
+
+## Использование
+
+### Автоматическое сжатие
+Сжатие происходит автоматически при добавлении новых сообщений, если включено в настройках.
+
+### Мониторинг
+Команда `/settings` показывает текущее состояние сжатия и параметры.
+
+## Преимущества
+
+1. **Экономия памяти** - значительное сокращение использования RAM
+2. **Улучшенная производительность** - быстрее обработка длинных диалогов
+3. **Сохранение контекста** - важная информация не теряется
+4. **Гибкость настройки** - возможность адаптации под различные сценарии
+5. **Обратная совместимость** - можно отключить без изменения кода
+
+## Обработка ошибок
+
+- При ошибках сжатия система автоматически переключается на простое обрезание истории
+- Логирование всех операций сжатия для мониторинга
+- Graceful degradation - бот продолжает работать даже при проблемах со сжатием
+
+## Производительность
+
+- Сжатие выполняется асинхронно, не блокируя основной поток
+- Использование кэширования для оптимизации повторных операций
+- Минимальное влияние на время отклика бота
