Abstract: Example solutions provide artificial intelligence (AI) annotated quality gating for code intelligence tools. A code intelligence tool update generates test results, which are evaluated by an evaluator, producing evaluation results. A quality score is determined for the evaluation results using a hierarchical quality criteria structure. This enables determination of whether the evaluator is providing a proper assessment of the code intelligence tool update (or may instead be rating the code intelligence tool update undeservedly high). If the evaluator is not providing a proper assessment of the code intelligence tool update, there is a risk that an underperforming update may be performed on the currently operational code intelligence tool, degrading the performance. The evaluator is tuned to improve the quality score. Using this two-tier assessment approach permits robust scaling.
