Prompt Optimization Score
Analyze prompt quality, measure prompt effectiveness, and improve AI responses using rule-based prompt engineering analysis.
Include 1-2 concrete 'Input: ... Output: ...' examples illustrating the exact desired transformation.
Replace hardcoded input blocks with dynamic variables like {{userQuery}} or {{inputText}}.
