Yeah its a fair point. I wondered if it might be irresponsible to publish the package because it was made this way, but I suspect I'm not the first person to try and develop a package with Claude Code, so I think the best I can do is be honest about it.

As for the workflow, I think the best advice I can give is to setup as many guardrails and tools as possible, so Claude and do as many iterations before needing any intervention. So in this case I setup pre-commit hooks for linting and formatting, gave it access to the full testing suite, and let it rip. The majority of the work was done in a single thinking loop that lasted ~3 hours where Claude was able to run the tests, see what failed, and iterate until they all passed. From there, there was still lots of iterations to add features, clean up, test, and improve performance - but allowing Claude to iterate quickly on it's own without my involvement was crucial.

I don't think it was irresponsible to publish it, but I do think it was irresponsible to publish it without clearly disclosing at the top of the crates.io README that it was built entirely by AI, and that you haven't reviewed the code (assuming you haven't).

If I were looking for an XML parser/generator library, I might stumble across this and think it might be production-quality, and assume it was built by humans, or at least that humans had fully vetted and understand the code.

Yes, if you tripped across this package in crates.io the readme gives the impression of a serious piece of software but your comments here imply it is a one off experiment rather than something you plan to maintain for the next decade.
