Construction is always a problem for large trees but sometimes it can’t be helped. It sounds like your tree is at least suffering from the shock of the root pruning. A good contractor should have noted that you have an oak tree in the location because it is best to prune oaks in the dead of winter.
From what you are saying, I wouldn’t worry as much about stability as insects and disease, though with all of the rain we have had, stability could be an issue.
Oak Wilt is the culprit I would worry the most about. We cannot diagnose anything online for certain. I would call an arborist to come look at the tree and make recommendations for you. Below are some links that should help you.
