Wiz overview

Wiz is Bourne-family shell with erasable type syntax. Executable files use .wiz; declarations for external commands, environment, and legacy libraries use .d.wiz. Invocation remains shell syntax:

declare -T string service="caddy"
restart_service(string name): status {
    systemctl restart "$name"
}
restart_service "$service"

Generated Bash, Zsh, or sh uses ordinary assignments, functions, positional parameters, quoting, and exit status. Untyped shell in the shared supported subset retains its behavior. Target validation reports constructs that cannot be represented safely by the selected shell.
