def evaluate_end_to_end(query, generated_answer, correct_answer):
    
    prompt = f"""
    You are an AI assistant tasked with evaluating the correctness of answers to questions about Anthropic's documentation.
    
    Question: {query}
    
    Correct Answer: {correct_answer}
    
    Generated Answer: {generated_answer}
    
    Is the Generated Answer correct based on the Correct Answer? You should pay attention to the substance of the answer, and ignore minute details that may differ. 
    
    Small differences or changes in wording don't matter. If the generated answer and correct answer are saying essentially the same thing then that generated answer should be marked correct. 
    
    However, if there is any critical piece of information which is missing from the generated answer in comparison to the correct answer, then we should mark this as incorrect. 
    
    Finally, if there are any direct contradictions between the correct answer and generated answer, we should deem the generated answer to be incorrect.
