Debugging can be super fun as we eliminate possibilities and it feels like we are converging to a solution. There have been instances where Claude (Opus family) was not able to effectively debug and I had to step in and do it. But debugging an over-engineered library for example, can become very wearisome. This is when I am really thankful for having Claude Code, it is able to figure out the bug and its fix/workaround pretty fast. I can then get back to doing my main task instead of spending an indefinite amount of time stepping through sloppily written code.
