I've updated the script with the capabilities of passing an ENV var $PROJECT, with the below function added to your vimrc, it can be set within your env or passed when you invoke your new script.

I've also revised my make_bash_script function to chmod +x and then vim the file you created

make_bash_script() {
SKELETON_URL=${BASH_SKELETON_URL:-"https://gist.githubusercontent.com/sempervent/4d94593e0d56f8fc1b43f92b9983d61f/raw/fe08f3de2b023dee323914ad564a5d746f4c6348/bash_skeleton.sh"}
wget -O "$1" "$SKELETON_URL"
chmod +x "$1"
vim "$1"
}

usage is

# this will make a bash script called "test.sh"
# this makes the script executable and opens the script in vim
make_bash_script test.sh
# if your project requires multiple scripts, you can EXPORT PROJECT or use project environment management
PROJECT="my silly project" test.sh >> more_specific_script.sh
