Symlinks are not created

I'm trying to automatically create symlinks so that I don't have to manually create them or copy files to ~/.config, but the symlinks just aren't created.

# modules/darwin/home/default.nix
{ options, config, lib, pkgs, inputs, ... }:

with lib;
with lib.shiro;
let
  cfg = config.shiro.home;
in
{
  options.shiro.home = with types; {
    file = mkOpt attrs { }
      "A set of files to be managed by home-manager's <option>home.file</option>.";
    configFile = mkOpt attrs { }
      "A set of files to be managed by home-manager's <option>xdg.configFile</option>.";
    extraOptions = mkOpt attrs { } "Options to pass directly to home-manager.";
  };

  config = {
    shiro.home.extraOptions = {
      home.stateVersion = config.system.stateVersion;
      home.file = mkAliasDefinitions options.shiro.home.file;
      xdg.enable = true;
      xdg.configFile = mkAliasDefinitions options.shiro.home.configFile;
    };

    snowfallorg.users.${config.shiro.user.name}.home.config = mkAliasDefinitions options.shiro.home.extraOptions;

    home-manager = {
      useUserPackages = true;
      useGlobalPkgs = true;
    };
  };
}

# modules/darwin/tools/sketchybar/default.nix
{ options, config, lib, pkgs, ... }:

with lib;
with lib.shiro;
let
  cfg = config.shiro.tools.sketchybar;
in
{
  options.shiro.tools.sketchybar = with types; {
    enable = mkBoolOpt false "Whether or not to install sketchybar";
  };

  config = mkIf cfg.enable {
    environment.systemPackages = with pkgs; [ sketchybar ];

    shiro.home.configFile.sketchybar = {
          source = config.lib.file.mkOutOfStoreSymlink ./config;
          recursive = true;
          executable = true;
        };
      };
    };

    services.sketchybar = {
      enable = true;
      package = pkgs.sketchybar;
    };
  };
}

I've already tried

configFile.sketchybar = {
    source = config.lib.file.mkOutOfStoreSymlink "~/.nix/modules/darwin/tools/sketchybar/config"
}

configFile.sketchybar = {
    source = config.lib.file.mkOutOfStoreSymlink "./config"
}

configFile.sketchybar = {
    source = "./config"
}

and the same with file."$HOME/.config/sketchybar" = {}

Start with modules/darwin/home/default.nix and modules/darwin/tools/sketchybar/default.nix, then trace how shiro.home.configFile is passed to home-manager's xdg.configFile. Reproduce the missing symlink with the shown sketchybar configuration and verify that the configured ~/.config/sketchybar link is created.
