## What it does
Takes any prompt and evaluates whether it's safe or unsafe with a confidence score, category, reasoning, and similar 
examples retrieved from a 180k prompt safety dataset.

## How it works
1. Your prompt is embedded and compared against 180k labeled prompts
2. The top 5 most similar prompts are retrieved as context
3. An LLM judge evaluates safety using that context
4. Returns: verdict + confidence + category + reasoning
