PQS - Prompt Quality Score

The world's first named AI prompt quality score. Score any LLM prompt before it hits any model — returns grade (A-F), score out of 40, percentile, and dimension breakdown across 8 quality dimensions. Built on PEEM, RAGAS, G-Eval, and MT-Bench frameworks. **Tools:** - score_prompt — Free. No API key needed. - optimize_prompt — $0.025 USDC. Returns optimized prompt + full breakdown. - compare_models — $0.50 USDC. Claude vs GPT-4o head-to-head. Cheaper than one bad inference call.
