• Add an XML doc comment for the IsPublic property to explain that it controls the visibility modifier of the generated builder class.

    public required bool IsPublic { get; init; }

src/DotNetCampus.CommandLine.Analyzer/Generators/BuilderGenerator.cs:78

• Add unit tests that verify builder code is generated with public when the command object is public and internal otherwise.

{{(model.IsPublic ? "public" : "internal")}} sealed class {{model.GetBuilderTypeName()}}

修不了 #51 的问题，我重新调查发现，这是由于没有生成 OptionsBuilder 导致的。只要 Options 没有任何标记，则 OptionsBuilder 不会生成

// Options.cs

namespace HalnerefaiwhoLanallwaynai;

public class Options
{
    public required string Name { get; init; }
}
