Those kind of tools should have the same name as the command they replace, I don’t want to change my workflow with this or that. I think a simple wrapper over cd with fzf is good enough and much simpler. Claude can probably write it in a few minutes.

Of course you can alias, but I was not very clear indeed. My point is that these tools ship multiple commands (z, zi, etc. autojump does too). I treat core shell commands as interfaces: keep the name, swap the implementation. If there's just one command, you can of course alias it (but why should I do this final step); if there are many, it turns into clutter. These tools should enhance existing commands instead of reinventing them: the goal is the same result, just faster and better. The philosophy is non-intrusive augmentation, like bash_completion or fzf.

That's what an alias is for. I don't want that behavior, but you are free to do it for yourself.

Or you could use shell aliases.
