-        This agent uses multiple specialized tools to handle diverse question types:
-        - Web search (Serper API + DuckDuckGo)
-        - Wikipedia search
-        - YouTube video analysis
-        - Text processing and reversal
-        - Mathematical problem solving
-        - Data extraction and botanical classification
-        
-        **Instructions:**
-        1. Log in to your Hugging Face account
-        2. Click 'Run Evaluation & Submit All Answers' to start the benchmark
-        3. The agent will process all questions and submit results automatically
-        
-        **Note:** Processing may take several minutes due to the complexity of questions.
