The tag wiki for sentence-construction currently says:
For questions about the proper construction of sentences.
This is quite a short description, which is probably too generic to be understood. In fact, some of the questions using that tag are questions that ask for a choice between words/phrases to use.
The tag is used for questions like the following ones.
How to identify the essential elements of this paragraph? It asks how to identify the elements of a paragraph
What is the meaning of "Between Anne and Jack's house there is just one vacant house"? It asks about the meaning of a sentence
What is another way to say "have a wedding ceremony"? It asks an alternative way of saying something
have/has + been + 3rd verb form It asks about the subject of a sentence being not known
Is it correct to use past perfect continuous with "during"? It asks about the tense to use
Restructuring the phrase to remove repetition It asks how to rephrase a sentence
Is this construction correct? It asks if a construction is correct
Is this a correct way of combining two conditional clauses? It asks how to combine two clauses to make a sentence
As I understand it, sentence-construction should be used in questions asking, for example, about how more sentences can be rephrased and joined to make a compound/complex/complex-compound sentence. Is that its purpose? If this is the purpose, only two of the listed questions should be using that tag.
Are there any tags that its tag wiki should reference (for example, using a sentence like "If the question is about [X] than use the-correct-tag-for-x)?
