Implement DSPy for Prompt Optimization

Implement a DSPy pipeline to programmatically optimize the prompts for your 'Content Analyzer' agent, specifically focusing on improving its ability to detect subtle 'hallucinations' or factual inaccuracies. Describe the chosen `Signature`, `Predict` module, and how you will use a small dataset of example content with known errors to `compile` the DSPy program. Provide relevant code snippets.
