A test case the skill fixed. Same model, same prompt, with and without the skill.

Prompt

Given a multi-class confusion matrix array `cm` (rows = actual, columns = predicted), write a Python function `get_class_specificity(cm, class_idx)` that calculates Specificity (True Negative Rate) for class `class_idx`. Specificity is TN / (TN + FP).

What was checked, without and with the skill
Checked	Without skill	With skill
Computes True Negatives by summing matrix elements outside row class_idx and column class_idx.	Missed	Passed
Computes False Positives by summing column class_idx excluding diagonal element cm[class_idx, class_idx].	Passed	Passed
