What is that modules = [ in shoemaker...? Looks highly suspicious. Just add agenix.nixosModules.default to your imports list right above it.

yeah that was a residue of me trying around

       Did you mean time?

I presume you meant age-plugin-yubikey? pcscd is required for that since that plugin communicates with the smartcard in the yubikey directly. If by "using the ssh-agent" you mean a -sk type key, then openssh would do that communication. That would require age to communicate to the ssh-agent which is not supported:

man age says

Note that keys held on hardware tokens such as YubiKeys
or accessed via ssh-agent(1) are not supported.

i've got gpg enabled via home-manager with the following settings

  programs.gpg.enable = true;
  services.gpg-agent = {
    enable = true;
    enableScDaemon = true;
    enableSshSupport = true;
  };

this is what makes my set up work

If you want to use both gpg and age-plugin-yubikey at the same time you have to disable scdaemon and force gpg to use pcsc lite too
