The fzf integration is a really nice touch here. Half the battle with dev tool management isn't installing things, it's remembering what you installed and how six months later. I know everyone's going to recommend Nix (and they already have), but there's something to be said for a solution where the entire logic fits in your head on first read. I've had a similar Makefile-based setup for years and the biggest win is onboarding new team members who can just read the targets and immediately know what's available.
