The types of tasks I have been putting Claude Code to work on are iterative changes on a medium complexity code base. I have an extensive Claude.md. I write detailed PRDs. I use planning mode to plan the implementation with Claude. After a bunch of iteration I end up with nicely detailed checklists that take quite a lot of time to develop but look like a decent plan for implementation. I turn Claude (Opus) loose and religiously babysit it as it goes through the implementation.
Less than 50% of the time I end up with something that compiles. Despite spending hundreds of thousands of tokens while Claude desperately throws stuff against the wall trying to make it work.
I end up spending as much time as it would have taken just to write it to get through this process AND then do a meticulous line by line review where I typically find quite a lot to fix. I really can't form a strong opinion about the efficiency of this whole thing. It's possible this is faster. It's possible that it's not. It's definitely very high variance.
I am getting better at pattern matching on things AI will do competently. But it's not a long list and it's not much of the work I actually do in a day. Really the biggest benefit is that I end up with better documentation because I generated all of that to try and make the whole thing actually work in the first place.
Either I am doing something wrong, the work that AI excels at looks very different than mine, or people are just lying.
