Our new off-topic close reasons have come in so handy and been so well used I think they do a good job of giving clear guidance to many on what they can expect they should avoid. Granted they're a subset, but they were chosen due to being such an extremely common subset.
Given that, I think we should add a piece to the help center under the "Asking" heading that lists out all of those fixed off-topic close reasons we have custom for our site, and a detail in the page listing them specifying these are not all the reasons your question may get closed, but these are some of the most common ones.
To be clear, I am asking for a link under the "Asking" heading, to a new page which lists the off-topic close reasons with or without any added explanation for each one that may be useful.
This could also go on the "What types of questions should I avoid asking" page we already have possible. Or have it on another page named something more clear like "What are the most common reasons questions are closed?"
I just think the actual text of those close reasons should be publicized somewhere as they were chosen by the community and have so far been found very effective in meeting much of our close reason needs, and as such may be helpful guidance for others to avoid closure ahead of time rather than finding that text only after having their question closed.
