Fair enough, at my job the code working consistently is absolutely the number one priority at all times but I can imagine that there are some places where this is not true. If working software isn't imporant then I agree agile is probably not the right choice

It's worth pointing out though that having insufficient documentation is not a feature of agile. Sounds more like laziness or misplaced priorities to me as documentation is called out as being useful in the agile principles, just not as important as working software.
