We have a delete reason of "link-only answer". But I often see answers which would be link-only answers if only they had links in them instead of just code.
I'd like to be able to indicate this to the answerer instead of just "no comment needed".
I fear that adding such a reason would send the wrong message.
Yes, there are abysmally bad answers that consist of nothing but code (sometimes utterly irrelevant code) which should be down-voted and (if not corrected) deleted with extreme prejudice. But I disagree strongly that "code only" is inherently a reason to delete an answer; heck, I've written answers where most of the explanation and guidance was in the form of comments within the code, and I actually prefer this for non-trivial listings, since there's a chance that readers will copy-paste them into production, and at least this way the guidance is preserved!
Remember, the canned comments aren't intended to be an exhaustive list of every sort of crap that bubbles up; rather, they're meant to provide useful guidance to misguided folks who can and may improve their (existing or future) contributions. If you come across an eye-bleedingly-bad answer in the queue and there's no reason that fits, don't hesitate to just select the "No comment needed" option and move on.
I think that maybe instead you should add a Code-Only exception toward the criteria for defining what's low-quality.
A question that's only code or mostly code most certainly can be a valid answer, and It seems to be the most common false-positive that the low-quality queue has.
on a separate, but still relevant note, I think it might be nice to include some sort of custom reason for your vote.
Not only will this catch un-anticipated reasons to close the question, but it will allow the reviewer to provide a more detailed explanation if he feels the need to.
How about adding a button in the action bar?
Quite often, with Low Quality Answers, I comment asking the poster to explain the code as opposed to just code-dumping.
Why can't there be a button to still allow me to collect my review credit, but doesn't constitute Recommending Deletion or flagging as Looks Good.
Like a 'Add Comment' button up in the action bar to encourage improvement instead of just flagging it as good or bad.
Generally speaking, the code-dump of the answerer should be good/substantial. Using @Josh Caswell's comment as an example, a question that only requires a trivial
So if they have added a large amount of code, asking them to explain it may help, instead of just deleting. The answer is fine, but doesn't really help future visitors (or indeed the asker) learn
