Creator prompt improvements

[Ribosome-2021]

There is a pattern that the current Creator, Creator_roop4 and Creator_roop5 prompts do not create the method well.
Specifically, some of the generated methods (new_method) are difficult to implement even when seen by a human, some of the methods are not well combined with each other, and some of the intentions of the combination are not clear.
To solve these problems, improvements will be made to the Creator prompts.
