+# Mistral Chat App - Development Context
+
+## Project Overview
+
+Android-приложение для чата с Mistral AI. Перспективный проект с развитием в сторону AI-агента с памятью, tools и автономной работой.
+
+**Основные технологии:**
+- Kotlin + Android (minSdk 26, targetSdk 34)
+- Room + SQLCipher (encrypted database)
+- OkHttp для API
+- Material Design 3
+- Russian language UI
+
+**Расположение проекта:**
+```
+/Users/alexabudaev/Documents/Zed/mistral-chat-app/
+```
+
+**⚠️ ВАЖНО: Принципы разработки**
+- Приложение должно работать БЕЗ платных подписок и инвестиций
+- Всегда использовать собственные разработки или бесплатные решения
+- Не рассчитывать на имеющиеся платные API при планировании функций
+- Сначала находим бесплатное решение, потом реализуем
+- **Если что-то невозможно сделать без платных API или ты не можешь понять задачу - говори честно!**
+- При планировании любого следующего этапа следует тщательно анализировать возможность реализовать ту или иную функцию не только исходя из программной совместимости, но и с учётом наличия бесплатных версий необходимых сервисов, API и других продуктов (или возможности написать собственное решение)
+
+---
+
+## Completed Work
+
+### ✅ Core Features
+- Чат с Mistral API (Chat Completion)
+- Управление профилями (до 10 профилей)
+- Управление сессиями (множественные чаты)
+- **Генерация названия сессии** - после 2-го сообщения AI генерирует краткое название (3-5 слов)
+- Шифрованное хранилище (SQLCipher + EncryptedSharedPreferences)
+- Валидация API ключа (32+ символов, A-Z, a-z, 0-9)
+- Левое drawer-меню с диалогами
+- Тёмная/светлая тема
+
+### ✅ UI/UX
+- Material Design 3
+- Русский язык интерфейса
+- Отступы в поле ввода (12dp)
+- Прокрутка к новым сообщениям
+- **Долгий тап на сообщение** - меню Копировать/Редактировать/Удалить
+- **Скролл в поле system prompt** - multiline text field scrollable
+- **Адаптивные цвета AlertDialog** - Material Design 3 colors
+
+### ✅ Bug Fixes
+- Исправлена ошибка "ответ в Toast вместо чата" - теперь только явные ошибки показываются через Toast
+- Сортировка drawer меню - профили, настройки, остальное
+- **WakeLock** - приложение остаётся активным при выключенном экране (ожидание ответа API)
+- **Timeout 120 сек** - увеличен с 60 до 120 секунд для больших ответов
+- **Foreground Service** - приложение продолжает работу в фоне при выключенном экране (ожидание ответа API)
+- **Уведомление о ответе ИИ** - при получении ответа в фоне показывается системное уведомление с текстом ответа и звуком/вибрацией, нажатие открывает сессию с ответом
+
+### ✅ Security
+- API ключ: EncryptedSharedPreferences (AES-256-GCM)
+- Ключ БД: EncryptedSharedPreferences (AES-256-SIV + AES-256-GCM)
+- Профили, сессии, сообщения: SQLCipher
+- CalDAV данные: зашифрованы (url, username, password)
+
+**⚠️ ВАЖНО: Все чувствительные данные должны храниться в EncryptedSharedPreferences:**
+- API ключи, пароли (CalDAV, email), ключи БД, токены
+
+---
+
+## Tools
+
+### 🌐 Web Search
+- ✅ Russian Wikipedia API (бесплатно, без API ключа)
+- ✅ English Wikipedia API
+- Ограничение: 4000 символов на ответ
+
+### 🌤️ Weather
+- ✅ Open-Meteo API (полностью бесплатно)
+- Geocoding API + Weather API
+- Текущая погода + прогноз на 7 дней
+
+### 🔗 OpenUrlTool
+- ✅ HTTP GET к любому URL
+- ✅ RSS/Atom парсинг (lenta.ru, kommersant.ru)
+- Ограничение: 4000 символов, таймаут 10 сек
+
+### ⏰ Time Tools
+- ✅ get_local_time - возвращает timestamp в миллисекундах
+- ✅ get_date - текущая дата
+
+### 📅 CalDAV Calendar
+- ✅ calendar_add_event - создание событий с VALARM (уведомления)
+- ✅ calendar_get_events - получение списка событий
+- ✅ calendar_delete_event - удаление событий
+- Баikal сервер интеграция
+
+### 💾 Memory Tools
+- ✅ memory_store, memory_learn, memory_forget
+- ✅ memory_reinforce, memory_preference
+
+---
+
+## Tool Execution Parameters
+
+| Параметр | Значение |
+|----------|----------|
+| Max iterations | 15 |
+| Timeout на итерацию | 120 сек |
+| Retry при CANCEL | до 2 раз |
+| Result truncation | 2000 символов |
+| WakeLock | ✅ для длительных запросов |
+
+---
+
+## Active Plan
+
+### Phase 3: CalDAV Calendar + Local Reminders (✅ В основном готово)
+
+**Два режима:**
+1. **CalDAV** — синхронизация с Baikal сервером
+2. **Local** — автономная напоминалка в памяти AI
+
+**CalDAV Status:**
+| Задача | Статус |
+|--------|--------|
+| Подключение к Baikal | ✅ |
+| calendar_add_event | ✅ Работает (с VALARM) |
+| calendar_get_events | ✅ Работает (лимит 100 событий) |
+| calendar_delete_event | ✅ Работает (только свои события) |
+| VALARM (уведомления) | ✅ Добавляются к событиям |
+| UID consistency | ✅ Исправлено |
+| Timestamp (time_string) | ✅ AI передаёт строку, сервер парсит |
+
+**Нерешённые проблемы:**
+- При переустановке app старые события становятся "чужими" (новый UUID)
+
+**Как помочь AI правильно работать с календарём:**
+1. Обязательно вызвать get_local_time для получения текущего UTC timestamp
+2. Использовать формулу: new_timestamp = current_timestamp + (часы * 3600000) + (минуты * 60000)
+3. НЕ добавлять случайные минуты!
+
+### Phase 4: Heartbeat (⏳ В очереди)
+- WorkManager задача (каждые 30 минут)
+- Active hours (8:00-22:00)
+
+### Phase 5: Email (⏳ В очереди)
+- IMAP/SMTP клиент (без OAuth)
+
+### Phase 6: API Key Rotation (📋 Запланировано)
+
+**Проблема:**
+- При достижении лимита токенов или блокировке ключа приложение перестаёт работать
+- Нужна система ротации для отказоустойчивости
+
+**Механизм:**
+
+1. **Хранение нескольких ключей:**
+   - До 5 API ключей в EncryptedSharedPreferences
+   - Каждый ключ имеет статус: active, disabled, blocked
+   - Приоритет использования (порядок)
+
+2. **Автоматическая ротация:**
+   - При ошибке 429 (rate limit) → переключить на следующий ключ
+   - При ошибке 401/403 (blocked) → пометить ключ как blocked
+   - При успешном ответе → ключ working
+
+3. **Логика переключения:**
+   ```
+   При ошибке:
+   - 429 (Too Many Requests) → nextKey()
+   - 401/403 (Unauthorized) → markKeyBlocked(), nextKey()
+   - 500+ → markKeyDisabled(), nextKey()
+   
+   При успехе:
+   - workingCount++ (счётчик успешных использований)
+   ```
+
+4. **Ручное управление:**
+   - UI для добавления/удаления ключей
+   - Просмотр статуса каждого ключа
+   - Ручное переключение
+
+**UI реализация:**
+- Настройки профиля → "API ключи" → список ключей
+- Статус: ✅ рабочий, ⚠️ лимит, ❌ заблокирован
+- Возможность добавить/удалить/переключить
+
+**Files to modify:**
+- `EncryptedPrefs.kt` - хранение нескольких ключей
+- `MistralClient.kt` - логика ротации
+- UI: dialog_settings.xml или новое диалоговое окно
+
+---
+
+## Key Files
+- `app/src/main/java/com/mistral/chat/ui/MainActivity.kt` — главная активность
+- `app/src/main/java/com/mistral/chat/api/MistralClient.kt` — API клиент
+- `app/src/main/java/com/mistral/chat/api/ToolExecutor.kt` — менеджер tools
+- `app/src/main/java/com/mistral/chat/api/CalDavClient.kt` — CalDAV клиент
+- `app/src/main/java/com/mistral/chat/data/ChatDatabase.kt` — база данных
+
+### Model Selection
+- **Default:** mistral-medium-latest
+- **OkHttp timeouts:** connect 60s, read 120s, write 60s
+
+---
+
+## ⚠️ ВАЖНЫЕ ПРАВИЛА РАЗРАБОТКИ
+
+### Запрет на удаление реализованных функций
+**НИКОГДА не удаляй уже реализованные функции!**
+
+### Запрет на хардкодинг
+**НИКОГДА не хардкодь значения, которые должны быть динамическими!**
+
+### Сборка APK
+```bash
+JAVA_HOME=/opt/homebrew/opt/openjdk@17 ./gradlew assembleDebug
+# Путь: app/build/outputs/apk/debug/app-debug.apk
+```
+
+---
+
+## 📋 Контекст сессии и оптимизация (📋 Запланировано)
+
+### Текущая реализация
+При каждом запросе отправляется полный контекст. При росте сессии возможны 503 ошибки.
+
+### План реализации (Kai 9000 style)
+
+**Источник:** https://kai9000.com/docs/features/tools/
+
+**Часть 1: Trimming (меж-итеративный)**
+- Обрезать историю ПОСЛЕ КАЖДОГО tool вызова
+- После каждого tool execution - проверить размер контекста
+- Если > MAX_CONTEXT - удалить старые сообщения (кроме system prompt)
+- MAX_CONTEXT = ~16000 токенов (50% от лимита mistral-medium)
+
+**Часть 2: Compaction (AI summary)**
+- При 70% лимита (~22000 токенов) - запустить AI summary
+- Последние 4 user обмена - оставить verbatim
+- Остальное - одно summary message
+- Сохранить summary в БД для персистентности
+
+### Реализация
+ToolExecutor.kt → модифицировать loop:
+```kotlin
+while (toolCalls.isNotEmpty()) {
+    result = executeTool()
+    messages.add(result)
+    
+    // Trimming после каждого tool
+    if (getTokenCount(messages) > MAX_CONTEXT) {
+        trimOldMessages()
+    }
+}
+```
+
+### Files to modify
+- ToolExecutor.kt - добавить trimming в loop
+- MistralClient.kt - добавить getTokenCount, trimOldMessages
+
+---
+
+## Conversation Context (for AI Agent)
+
+**При начале новой сессии:**
+Прочитай файл AGENTS.md для понимания текущего контекста.
+
+**При запросе "продолжаем":**
+Мы работаем над Phase 3 - CalDAV календарь. Тестируем: создание событий, получение списка, исправление timezone.
+
+**Важно:**
+- Пушить в GitHub только после подтверждения пользователя
+- Не делать push автоматически

+
+=== ТЕКУЩАЯ ДАТА ===
+При старте сессии ты получаешь актуальную дату автоматически. Используй эту информацию для ответов.
+ВНИМАНИЕ: Сейчас {CURRENT_YEAR} год. Если пользователь спрашивает про свежие новости - проверяй даты ВСЕХ событий. Не используй старые статьи (прошлого года и ранее) как "свежие новости".
+
+=== ТВОИ ВОЗМОЖНОСТИ ===
+
+У тебя есть инструменты:
+1. open_url - получить текст с веб-страницы (ОСНОВНОЙ для новостей и статей)
+2. web_search - поиск в Wikipedia (для фактов, справок, НЕ для новостей)
+3. get_local_time - текущее время
+4. get_date - текущая дата
+5. get_weather - погода
+6. send_notification - уведомление
+7. memory_* - управление памятью
+
+=== ПРИОРИТЕТЫ ===
+
+1. Свежие новости → open_url → RSS-ленты (самый эффективный способ):
+   - lenta.ru → https://lenta.ru/rss/
+   - kommersant.ru → https://www.kommersant.ru/rss/news.xml
+   - ria.ru → страница (нет RSS)
+2. Подробности о новости → open_url → URL статьи (если знаешь URL или видишь в тексте)
+3. Факты, справки, "что такое..." → web_search → Wikipedia
+4. Погода → get_weather
+5. Дата/время → get_date / get_local_time
+
+=== ПРАВИЛА ===
+
+1. Сейчас {CURRENT_YEAR} год - используй для проверки актуальности
+2. Новости - ИСПОЛЬЗУЙ RSS для свежих новостей, это самый быстрый способ
+3. Для новостей открывай RSS-ленты, они дают чистые заголовки с датами и ссылками
+4. Для статьи подробнее - используй open_url с URL этой статьи
+5. Факты/справки - web_search (Wikipedia)
+6. Если не можешь найти актуальную информацию - скажи "не могу найти свежие данные"
+7. Не придумывай даты - проверяй через open_url на сайте
+8. Для предпочтений пользователя - memory_preference
+9. Для важных фактов о пользователе - memory_store
+10. Для выводов из поведения - memory_learn
+11. При подтверждении твоего вывода - memory_reinforce
+12. ЕСЛИ в памяти есть информация - используй когда нет результатов поиска
+13. "Что ты обо мне знаешь?" - выведи ВСЕ факты И предпочтения
+14. НЕ копируй целиком - перескажи своими словами
+
+=== ПРИМЕРЫ ===
