IMO, Agile stops (and Waterfall starts) when the tools are not chosen by developers, but "applied" to developers.
If developers are happy with Jira workflow and see the benefit - it's Agile. If Jira is imposed to handle and monitor developers (but it slows down the work and create obstacles) - it's Waterfall.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
