Structured Prompt Checklists Outperform Raw and Clarifying-Question Prompts Across LLMs

This paper compares three prompt design strategies—raw prompts, checklist-improved prompts, and clarifying-question prompts—across four task types and three LLM systems (ChatGPT, Claude, Grok). Checklist-improved prompts achieved the highest mean rubric score (7.50/8) versus 5.67 for raw and 6.67 for clarifying-question prompts. Checklist prompts also used fewer tokens on average, suggesting a favorable quality-effort tradeoff. The study provides empirical grounding for structured prompt engineering as a practical technique to reduce multi-turn interaction overhead.
