Thank you for working on this.

I think it would better suited to add from_funciton method as we have in Tool and Templave and there do things like func_doc = description or fn.__doc__ or ""

Please can you also add tests? #501 had some tests related to this.

Thanks for your comment. I add from_funciton into FcuntionResourse class.
