Like any tool, you get better at using it. YMMV indeed.

The author of this article could probably have, for example, written most of this into the project’s Claude.md and the AI would learn what not to do.

Instead they wrote it up as a blog post which is unsurprisingly not going to net quality software.

Having some way for Claude to test what it wrote is critical as well. It will learn on its own very fast if it can see the error messages and iterate on it like any other developer would

Sounds like the author had tests that Claude never ran. Sounds misconfigured to me. Again, did the author learn how to use the tool?
