This is very interesting, and nice learnings in there too, thank you for sharing! It seems the author monitored the LLM, stopped it from going off-track a few times, fixed some unit test code manually, etc. Plus this is strictly re-implementing a very well-specced library that already exists in the same programming language. So I think it's still a bit hard to say we can let an LLM work for multiple days, if we imply that this work should be domain-specific to a particular company. But it's very promising to see this was possible with very little interaction!
