It seems like argument() must be provided by classes using this trait. How about adding it as abstract method to this trait?

            $this->slug = Str::slug($slug, '_');
        }

        return $this->slug;
    }

    protected function roleIsExist(): bool
    {
        return $this->searchExist(Role::class, $this->slug());
    }

    protected function roleIsDoesntExist(): bool
    {
        return ! $this->roleIsExist();
    }

    protected function permissionIsExist(): bool
    {
        return $this->searchExist(Permission::class, $this->slug());
    }

    protected function permissionIsDoesntExist(): bool
    {
        return ! $this->permissionIsExist();
    }
