- "Yes": The agent clearly performed well regarding the criteria in the question.
- "No": The agent clearly performed poorly or inadequately regarding the criteria in the question.
- "NA": The conversation did not provide any relevant scenario or sufficient context to evaluate the agent against this specific criteria.

    {{
        "Question": "<Question>",
