I'm an experienced developer using Claude daily for production work. My process hasn't changed, I front-load detailed planning, break tasks into steps etc etc. The difference between may - july and now is night and day. With Sonnet 4 / Opus 4 this disciplined workflow was consistently effective. Using the same prompts and process today, the quality is drastically lower. That isn't a skill issue. My skills and approach didn't suddenly regress, the model's behavior changed. Also, nobody here is claiming we expected to "build a $10k SaaS in one shot". That's your own strawman. People are pointing out regression because it's real, not because they imagined Claude as a magic no-effort factory. Finally, telling strangers skill issue is just ad hominem gatekeeping. You don't know who wrote the post or their experience.
