Craft a clear set of instructions for the AI model. This prompt will guide the model in assessing a generated output on criteria you define, and then assign a specific score based on this criteria. Your instructions must use {{output}} for the model's generated response and can optionally use {{input}} for the original user prompt, {{history}} for chat history, and {{expected_output}} for the ground truth. These variables will be replaced with actual data from your dataset during evaluation.
