Can you explain more about what you mean?
cybereality When the mouse stops on the editor node, it will prompt the description of the attribute. How can I set this description
No, this is not supported, but it looks like it was worked on and never merged. https://github.com/godotengine/godot/pull/35716

I could have sworn there was some discussion on this wrt godot 4 @attributes but I don't recall what came of it. Looks like _get_property_list() can define hint and hint_string tho: https://docs.godotengine.org/en/latest/classes/class_object.html#class-object-method-get-property-list
_get_property_list()
The example isn't written out like above but seems this should be possible in godot 3.6 and below as well: https://docs.godotengine.org/en/3.6/classes/class_object.html#class-object-method-get-property-list
