+# YouTube Интеграция - Руководство пользователя
+
+## Обзор
+
+Гибридный GAIA агент теперь поддерживает полную интеграцию с YouTube, позволяя анализировать видео и отвечать на вопросы о их содержании.
+
+## Возможности
+
+### 1. Извлечение метаданных
+- **Название видео**
+- **Канал/автор**
+- **Длительность**
+- **Количество просмотров**
+- **Дата публикации**
+- **Описание**
+- **Теги**
+
+### 2. Извлечение транскриптов
+- **Автоматические субтитры**
+- **Ручные субтитры**
+- **Множество языков** (английский, русский, и др.)
+- **Поиск по содержанию**
+
+### 3. Анализ содержания
+- **Поиск конкретных фраз**
+- **Извлечение ключевой информации**
+- **Ответы на вопросы о видео**
+
+## Установка зависимостей
+
+```bash
+pip install yt-dlp youtube-transcript-api
+```
+
+### Опционально (для расширенной функциональности):
+```bash
+# Установите YouTube API ключ
+export YOUTUBE_API_KEY="your_api_key_here"
+```
+
+## Примеры использования
+
+### 1. Базовые вопросы о видео
+
+```python
+from hybrid_agent import HybridGAIAAgent
+
+agent = HybridGAIAAgent()
+
+# Получить название видео
+question = "What is the title of this YouTube video: https://www.youtube.com/watch?v=dQw4w9WgXcQ"
+answer = agent(question)
+# Ответ: "Rick Astley - Never Gonna Give You Up (Official Music Video)"
+
+# Узнать длительность
+question = "How long is the video at https://www.youtube.com/watch?v=dQw4w9WgXcQ?"
+answer = agent(question)
+# Ответ: "212" (секунд)
+```
+
+### 2. Вопросы о содержании
+
+```python
+# Анализ содержания видео
+question = "What is this YouTube video about: https://www.youtube.com/watch?v=example"
+answer = agent(question)
+
+# Поиск конкретной информации
+question = "Does the video at https://www.youtube.com/watch?v=example mention artificial intelligence?"
+answer = agent(question)
+```
+
+### 3. Поддерживаемые форматы URL
+
+```python
+# Все эти форматы поддерживаются:
+urls = [
+    "https://www.youtube.com/watch?v=dQw4w9WgXcQ",
+    "https://youtu.be/dQw4w9WgXcQ",
+    "https://www.youtube.com/embed/dQw4w9WgXcQ"
+]
+```
+

+
+### Обработка ошибок
+
+Система имеет встроенные fallback механизмы:
+
+1. **YouTube API** → **yt-dlp** (для метаданных)
+2. **Ручные субтитры** → **Автоматические субтитры** → **Без транскрипта**
+3. **Graceful degradation** при недоступности сервисов
+
+### Поддерживаемые языки транскриптов
+
+- Английский (en)
+- Русский (ru)
+- Немецкий (de)
+- Французский (fr)
+- Испанский (es)
+- И многие другие...
+
+## Ограничения
+
+### 1. Зависимости от внешних сервисов
+- YouTube может блокировать запросы
+- Не все видео имеют транскрипты
+- Некоторые видео могут быть недоступны в регионе
+
+### 2. Производительность
+- Извлечение транскриптов может занимать время
+- Большие видео требуют больше ресурсов
+
+### 3. Точность
+- Автоматические транскрипты могут содержать ошибки
+- Качество анализа зависит от качества транскрипта
+
+## Отладка
+
+### Включить подробное логирование:
+
+```python
+import logging
+logging.basicConfig(level=logging.INFO)
+```
+
+### Проверить доступность зависимостей:
+
+```python
+from youtube_tools import YouTubeTools
+
+tools = YouTubeTools()
+# Проверьте логи на предупреждения о недоступных зависимостях
+```
+
+### Тестирование:
+
+```bash
+python test_youtube.py
+```
+
+## Примеры реальных GAIA задач
+
+### 1. Анализ образовательного контента
+```
+"Summarize the main points discussed in this educational video: [URL]"
+```
+
+### 2. Извлечение фактической информации
+```
+"What year is mentioned in this historical documentary: [URL]"
+```
+
+### 3. Анализ музыкального контента
+```
+"Who is the artist of the song in this video: [URL]"
+```
+
+## Заключение
+
+YouTube интеграция значительно расширяет возможности GAIA агента, позволяя обрабатывать видео-контент наравне с текстовыми и другими мультимодальными данными. Это делает агент более универсальным и готовым к реальным задачам, где видео является важным источником информации.

Your final answer should be a number OR as few words as possible OR a comma separated list of numbers and/or strings. If you are asked for a number, don't use comma to write your number neither use units such as $ or percent sign unless specified otherwise. If you are asked for a string, don't use articles, neither abbreviations (e.g. for cities), and write the digits in plain text unless specified otherwise. If you are asked for a comma separated list, apply the above rules depending of whether the element to be put in the list is a number or a string.
+
+IMPORTANT: For reverse/word puzzle questions, think carefully about what is being asked:
+- If asked to "reverse" a string that contains words, first reverse the string literally, then understand what it says
+- If the reversed string says something like "'left' as the answer", the actual answer should be the opposite concept (e.g., "right")
+- For mathematical tables or logical puzzles, analyze the pattern carefully
+
+For factual questions with context: Use the available information to provide the best possible answer, even if the information is not perfectly complete. Try to extract useful details from the context.
+
+For music questions: When counting albums, distinguish between:
+- Studio albums (original recordings in a studio)
+- Live albums (concert recordings, often marked as "Live", "En Vivo", "Acústico")
+- Compilation albums (collections of existing songs, "Greatest Hits", "Best of")
+- Awards (Grammy awards are NOT albums)
+- If you see album titles with years, count them carefully for the specified time period
+- If an album is described as "double album" with two parts (like "Cantora 1" and "Cantora 2"), count it as ONE album, not two
+- Look for explicit mentions of "studio album" or context clues about recording type
+
+CRITICAL: Your response should be ONLY the final answer - no explanations, no reasoning, no additional text. Just the direct answer to the question.
+
+Do NOT use "FINAL ANSWER:" prefix in your response. Just provide the answer directly."""
