.out does not seem to be executed

[ghost]

I have very simple .in and .out in the same directory.

% cat .in
echo 'autoenv: in'
% cat .out
echo 'autoenv: out'
%

Content of .out never seems to be executed:

~ ❯ zsh -f -d
% source ~/.local/share/zsh/bundle/zpm-zsh/colors/colors.plugin.zsh
% source ~/.local/share/zsh/bundle/zpm-zsh/autoenv/autoenv.plugin.zsh
% cd Sites/foo/

> WARNING
> This is the first time you are about to source "/Users/user/Sites/foo/.in"

----------------

echo 'autoenv: in'
----------------

Are you sure you want to allow this? (y/N) y
autoenv: in
% cd ..
%

ZSH version is zsh 5.8 (x86_64-apple-darwin19.3.0).
