.github/workflows/flake-check.yaml:8

• [nitpick] Confirm that your Nix environment and dependencies work on macOS runners; if Linux is preferred for consistency, consider reverting to ubuntu-latest.

    runs-on: macos-latest

.github/workflows/flake-check.yaml:13

• The trailing -- -L flag will be passed to your regen script rather than as a Nix override; remove or replace it with the intended --override-input flake-file "$PWD" flags.

      - run: nix run -L --override-input flake-file $PWD ./dev#regen -- -L

modules/options.nix:21

• Verify that lib.types.str is a valid alias for string; if not, revert to lib.types.string or add an alias in lib/types.nix to avoid type errors.

    type = lib.types.str;
