    To integrate agentic analysis into your existing Dubsway system:
    
    1. Set up Groq API key:
       - Get API key from https://console.groq.com/
       - Set environment variable: GROQ_API_KEY=your_key_here
    
    2. Replace the analyze function call in worker/daemon.py:
       - Change: transcription, summary = await whisper_llm.analyze(...)
       - To: transcription, summary = await agentic_integration.analyze_with_agentic_capabilities(...)
    
    3. Add new dependencies to requirements.txt:
       - opencv-python
       - pillow
       - duckduckgo-search
       - wikipedia-api
       - langchain-groq

    - Context-aware summarization using Groq llama-3.3-70b-versatile
    - Beautiful, comprehensive reports
    - Enhanced vector embeddings for better RAG
    - Web search integration for context
    - Wikipedia lookups for detailed information
    - Open-source model support with Groq
