Review and critique prompts (system prompts, few-shot exemplars, tool descriptions, dataset prompts) used in the GEM-LLM project for clarity, leakage, ambiguity, length, language-mix risk, and Gemma/EXAONE-specific failure modes. Use when the user says "프롬프트 리뷰", "이 프롬프트 봐줘", "system prompt 리뷰", "few-shot 검토", "프롬프트 개선", "프롬프트 평가", "tool description 리뷰". Produces a structured rubric (clarity / specificity / safety / format / language / token-cost) with concrete rewrite suggestions. Knows that K-EXAONE produces English CoT, so Korean output requires explicit constraints.
