I'm considering using the API for a retag job not supported by existing tooling as per this meta post (of course, I'll make sure the community supports the effort before going forward).
I'm planning to use Py-StackExchange (didn't yet looked into details, so may have to consider something else if it doesn't support retagging; also considered FixAllTheTags but it doesn't allow to set an edit summary)
The problem is: since I'll need write access, I'm going to have to register a Stack App to get an API key. For which, I'll need to provide an app's name, functionality, where it's hosted, its official site, etc.
But, none of that is applicable to my use case. It won't be a web app, nor am I going to let arbitrary users use it, or make an official site and arrange its hosting, all just for the sake of a few hours' work. Nor is there a name or a predefined set of functionality - it's going to just be various odd jobs from time to time as the need arises.
How shall I go about this?
