It's not unusual for my initial output (as a programmer) not to compile either. I wouldn't say I "failed" if I can then get it to compile. Which as people are saying, is what happens with Claude Code and Opus, either automatically or at most when I say "get it to compile".

Hmm…if you’re giving only one prompt to Claude Code, and allowing it only one output, then I’m no longer baffled at why you’re not getting good results. That’s not how it works. (That’s not how it works when I write code myself, either!)
