Formula Used

Prompt Evaluation Score = Weighted Design Score + Governance Bonus + Parameter Modifiers - Risk Penalty.

Weighted Design Score = Σ[(criterion score / 10) × criterion weight × 100]

Governance Bonus = (Compliance Need × 0.25) + (Input Quality × 0.20) + (Reference Coverage × 0.25)

Risk Penalty adds deductions when hallucination tolerance is high, latency is unrealistically low, or too many prompt variants increase operating overhead.

Reliability Index combines clarity, specificity, evaluation criteria, and grounding. Control Index blends constraints, format control, and safety. Efficiency Index combines efficiency scoring with token and iteration settings.

How to Use This Calculator

  3. Rate each evaluation factor from 0 to 10 using your current prompt draft.
  4. Click Evaluate Prompt to generate the overall score and improvement notes.
  5. Review the result section above the form for grade, indices, weaknesses, and recommendations.
  6. Use the CSV option for spreadsheet analysis or the PDF option for reporting and team reviews.

8 FAQs

1. What does this prompt evaluation tool measure?

It measures prompt quality across clarity, context, specificity, safety, grounding, format control, and operating efficiency. The goal is to estimate reliability before deploying a prompt in production or testing.

2. Is a high score always enough for production?

No. A strong score indicates design quality, but real deployment still needs task testing, bias checks, failure analysis, and version comparison under realistic inputs.

3. Why is grounding important in prompt design?

Grounding reduces unsupported claims by giving the model clear references, context boundaries, or retrieval sources. Strong grounding usually improves consistency and lowers hallucination risk.

4. How should I rate the scoring fields?

Use 0 for missing quality and 10 for excellent quality. Rate honestly based on the current draft, not the intended final version, so the calculator can show genuine improvement opportunities.

5. What temperature range works best for reliable prompts?

For structured, factual, or repeatable tasks, lower settings often work better. Creative use cases may tolerate higher values, but consistency usually drops as randomness increases.

6. Can this calculator compare multiple prompts?

Yes. Run each prompt separately, export the results, and compare scores, indices, and detected issues. This makes A/B testing more structured and easier to document.

7. What makes a prompt production ready?

Production-ready prompts usually define the task clearly, include precise constraints, specify output format, use source grounding, and contain evaluation checks for acceptable responses.

8. Does this replace human review?

No. This tool supports structured review, but expert oversight is still needed for sensitive workflows, regulated tasks, brand voice alignment, and domain-specific accuracy validation.
