How Scoring Works
90%
Test Success Rate
Percentage of test cases that pass. This measures whether the AI-generated code actually works correctly.
10%
Code Quality
Based on RuboCop static analysis. Quality score decreases linearly from 100 to 0 as offenses increase from 0 to 50.
RuboCop uses strict default settings and may not reflect real-world code quality preferences. The quality score should be interpreted as adherence to Ruby style guidelines rather than overall code quality.
📐
Calculation Formula
Score = (Test Success Rate × 90%) + (Quality Score × 10%)
Quality = 100 - ((RuboCop Offenses ÷ 50) × 100), capped 0-100
