thanks for your contributing, i've left some notes inline

the checks are failing because in this scope cfg is referencing the nixos modules's options, not the stylix module's. you'll need to modify this config segment to take { cfg } as an argument and rename the existing cfg. something like this:

config = [
  (
    { cfg }:
    {
      warnings =
        let
          hmCfg = config.programs.regreet;
        in
        # ...

maybe an option name that's a little more clear, something like this:

Suggested change

	disableCustomGreetdWarning = lib.mkOption {
	description = ''
	Disable warning produced by this module when using custom `services.greetd.settings.default_session.command`.
	silenceCustomSessionCommandWarning = lib.mkOption {
	description = ''
	Silences the warning produced by this module when using custom `services.greetd.settings.default_session.command`.

Suggested change

	example = "true";
	example = true;

could you also mention the option to silence the warning in the warning itself please
