Return to Question

When reviewing low-quality posts, the help text explains:

• Looks Good if nothing is wrong with this answer
• Edit if you can fix all the problems with this answer
• Recommend Deletion to recommend that this answer be deleted
• Not Sure if you are unsure and want to skip this answer

But there is no guidance as to the thresholds. In particular, the text gives me no idea how bad a post has to be for me to be supposed to recommend deletion. For example, the most common gray area is with answers consisting of one or two lines of code. Often these can technically answer the question, but they are not very useful because they don't explain why or how it works. Should those be deleted? If not, should I really say "looks good" even though something is "obviously wrong with this answer"?

Could the help text be clarified (or at least hyperlinked to an explanation)?
