Using the sandbox is unnecessary in many circumstances (think this), especially if you are a good question writer.
However, it is not always obvious (at least to me) if a question needs to go through the sandbox process.
For example, I considered Prime Quine to be a straightforward question, although it was recommended for the sandbox.
My question is, What qualities are "problem points", that is, what qualities require extra clarification?
An example based on Prime Quine would be:
Define what built in functions can be used thoroughly, especially for well known mathematical structs, like prime numbers.
I am hoping this resource will help people create better questions, as well as help with the sandbox process.
