Prompt Quality Scorer — Score Any Prompt 0-100
Paste any AI prompt. Get an instant 0-100 quality score across 6 dimensions, plus specific suggestions to improve. Calibrated to the 2026 prompt-engineering scaffold.
The 6 dimensions we score
- Role definition (15 pts): Is there a specific role with credentials? "Senior security engineer with 10 years" beats "expert."
- Principles (15 pts): Are quality bars + constraints encoded? Numbered principles outperform vague guidance.
- Input structure (20 pts): Is input wrapped in tags or clearly labeled?
<input>tags beat inline mixing. - Output format (20 pts): Is the output structure specified? "Output JSON: {...}" or markdown headings.
- Examples (15 pts): Few-shot examples present for tone/format you can't describe?
- Constraints + negative space (15 pts): "Do NOT..." patterns and explicit refusals.
