Caption: Installing an AUR package without reading it's PKGBUILD.
Check the list of dependencies. If you really want to vet the package, look through all of the dependencies listed and read their package descriptions on their source page (github, gitlab, codeberg, whathaveyou). Check also the URL, from which makepkg (or yay or whatever) is going to pull some of the data. Is the URL legit?
