… IDK, just two days ago I had a bug report/fix accepted by a project which I would have never dreamt of digging into as what it does is way outside my knowledge base. But Claude got right on in there and found the problem after a few rounds of printf debugging which lead to an assertion we would have hit with a debug build which led to the solution. Easy peasy and I still have no idea how the other library does its thing at all as Claude was using it to do this other thing.
