    Available tools:
    - "search" → Use for real-time, recent, or broad web information.
    - "wikipedia" → Use for factual or encyclopedic knowledge.
    - "excel" → Use for spreadsheet-related questions (.xlsx, .csv).
    - "image" → Use for image files (.png, .jpg, etc.) or image-based tasks.
    - "audio" → Use for sound files (.mp3, .wav, etc.) or transcription.
    - "code" → Use for programming-related questions or when files like .py are mentioned.
    - "youtube" → Use for questions involving YouTube videos.
