> the current approach isn't delivering the desired engineering requirements. Maybe we need to rethink

I'm reminded of the times I've tried to let Claude fix some well-documented bug in the background, and it ends up burning 4 million tokens and 20 self-review cycles re-writing the same set of code a dozen times with ever more complex unit test mocks / overcomplicated regexes / giant comments restating the same thing the code does, when the actual fix turned out to be "change three to ten lines to do something in a slightly different way that avoids the problem entirely".
