On macOS the Bash tool runs zsh. A loop like `for x in "A3 393 adonix" ...; do set -- $x; cmd $1 $2 $3; done` works in bash but not in zsh: zsh does not split unquoted parameters by default, so $1 was the full string "A3 393 adonix" and the command failed with a file name like `A3 393 adonix.md: no such file`. Fix: use ${=x} (zsh split flag), or skip the split and call a small function with explicit args, e.g. `e(){ gh pr edit $2 ... $1.md; }; e A3 393 adonix`. The function form works in both shells.
