How to tag some SVA issue

I tried to get language tool to check “Students is advised to be punctual”. It failed to detect the wrong use of the auxiliary verb ‘is’. It should be ‘are’.

Using Chunks - LanguageTool Wiki describes how to find chunks. The more general introduction on how to write rules can be found at Development Overview - LanguageTool Wiki.

Ok, thanks. I will try to understand and more on from there.
