Explanation:
In English it is common to end sentences with another short phrase, with the opposite sign, which is intended to ask for the opinion or seek the approval of the interlocutor: these are called question tags.
To form this short question we will use the auxiliary of the main phrase and its subject but with the opposite sign. If it had no auxiliary then we would use the auxiliary "to do".
If the sentence is affirmative, the question tag is negative and vice versa.
In the case of the verb "ought" it is allowed to use the auxiliary "should", as the verb "ought" is not that so used. But in the first sentence, it would be ok to use "oughtn't" too.
