So, we have a magic tag. It's a fine tag, and there's nothing majorly wrong with it. Part of its usage advice in the tag wiki, though, says:
Questions that merit more specific tags should not also use magic. Instead:
- Questions about the interpretation, use, or interactions of specific spells should use spells.
In general, that's good advice. Usually, general and specific tags sit side by side when new users are trying to figure out what to put on their question and haven't figured out the folksonomy yet.
In actuality, though, sometimes the tag should be next to specific tags, even the spells tag. For example, Is a caster aware of a thin sheet of lead blocking detect magic? is primarily about the usage of detect magic in 3.5, but is also substantially a question about how magic itself works in 3.5 and what the absence of magic auras is, if that's even a thing. Basically, it's both about the detect magic spell and about magic in general, because those things happen to be weirdly and inordinately tight in 3.5's system (like, for example, lots of rules about magic in general that have nothing to do with detect magic appear nowhere other than the detect magic spell description, or other discussions of the spell's abilities elsewhere).
Furthermore, it's against SE policy for us to have meta tags (i.e. tags with special rules about their usage beyond those inherent in categorizing the question), which this policy, as-is, self-mandates.
Therefore, it seems like this advice is misguided and should be excised. However, possibly I am misunderstanding something or ignorant of a pressing need. Is there a reason this advice ought not to be/have been eliminated? (I'ma go edit the tag wiki now, while we discuss this).
