Claude will also tend to go for the "test-passing" development style where it gets super fixated on making the tests pass with no regards to how the features will work with whatever is intended to be built later.

I had to throw away a couple days worth of work because the code it built to pass the tests wasn't able to do the actual thing it was designed for and the only workaround was to go back and build it correctly while, ironically, still keeping the same tests.

You kind of have to keep it on a short leash but it'll get there in the end... hopefully.
