Develop Multimodal Response Evaluation Agent

Develop the 'Model Response Evaluator' agent. This agent will receive multimodal prompts and model responses (e.g., from Ernie 5.0 or Gemini 2.5 Pro) via A2A Protocol. Implement logic using DSPy to critically assess the quality, accuracy, coherence, and safety of the multimodal responses. Define a scoring mechanism and provide a textual justification for the scores. Integrate it to receive input from the 'Adversary Prompt Generator'.
