可不是 is a fixed conversational response expressing emphatic agreement, roughly exactly or you can say that again. It may stand alone or introduce a confirming clause. The sequence 可+不+是 remains intact in this use; particles, topics, and predicate material cannot be inserted inside its three mandatory slots. Keep the model 可不是 + (Clause) visible while you compare each sentence.
可不是，今年夏天特别热。
Exactly; this summer is especially hot.
Choose the right context
Use 可不是 as an emphatic agreement response. Use it before a clause that confirms the previous speaker. Use conversational intonation appropriate to strong concurrence.
可不是吗，我也等了半天。
Isn't that the truth? I waited ages too.
Respect the boundary
Do not insert aspect inside the fixed formula. Do not put a topic noun between 不 and 是. Do not omit 是 from this agreement response.
可了不是，今年夏天特别热。
(Exactly; this summer is especially hot.)
Repair the pattern
Aspect marker splits fixed agreement formula: 可不是 is an intact response formula and cannot contain aspect 了. Topic noun splits mandatory marker sequence: No topic noun may intervene between mandatory 不 and 是 in the fixed agreement formula.
可不是，今年夏天特别热。
Use the repaired structure without changing the intended meaning.
