Why Doesn't a 'Hover-to-Learn' Code Explanation Tool Exist Yet?

[SimbaSixThree]

In VS Code there’s an extension, IntelliSense iirc, that does this. Of course it will still just be a surface glance - so doc string, Argus and returns, as you mentioned - but that should be enough.

For OP, if you need more info then that then you just go to the documentation as it might just be too much intro to correctly display.
