Check flask-swagger comments

Question

Flask-swagger takes docstrings like the following to create swagger specifications.

I would like to have a tool which automatically checks if the docstring has obvious errors. The errors could be formatting issues or missing parts (e.g. if there is a request.args['foobar'] in the function body, then foobar must be in the parameters part). Does something like this exist?
