Your laptop has ripgrep, installed via cargo install. ruff is there too, via uv tool install. golangci-lint came from go install. bash-language-server was npm i -g. Neovim was a tarball download. Kitty was a curl script. Six months later you get a new machine, or you just want to upgrade or reinstall. What do you even have installed? How did you install each one? Which version? Good luck. This is a small system that answers those questions — a single Makefile that declares every tool you care about, grouped by purpose, with one command to install anything.
