There is already a project using the name smartcd to patch the shell cd command. It exists at https://github.com/cxreg/smartcd.
I don't really want to start a fight over naming or anything like that. I suggest that both projects provide a short statement saying something like "if you're looking for OTHER SMARTCD that does THE OTHER THING you can find it at THE OTHER SMARTCD PROJECT URL".
I have a commit bit on the other smartcd, and can update the readme accordingly.
