Claude Code proves you don't need quality code — you just need hundreds of billions of dollars to produce a best-in-class LLM and then use your legal team to force the extreamly subsidised usage of it through your own agent harness. Or in other words, shitty software + massive moat = users.

Seriously, if Anthropic were like oAI and let you use their subscription plans with any agent harness, how many users would CC instantly start bleeding? They're #39 in terminal bench and they get beaten by a harness that provides a single tool: tmux. You can literally get better results by giving Opus 4.6 only a tmux session and having it do everything with bash commands.

It seems premature to make sweeping claims about code quality, especially since the main reason to desire a well architected codebase is for development over the long haul.
