People who don't review the code are ignorant and you should not trust any of their opinions. Vibecoding without reviewing code experiment (spoiler 2.10 billion tokens wasted): Prd: - /goal: implement 66 refactoring steps by Martin Fowler - guardrailed with docs, skills & deterministic tools (linter, ast, codegen, jujutsu) - stack defined (Yuku, Typescript compiler) - gpt-6-astra Results: - spaghetti code everywhere - 66 refactorings 'working' but interface design horror - 0/66 usable without limitations - 2,501 reported code smells (wtf) - 3 resets used / 5 days later Thank god it did TDD how I asked (first cleanup pass: 562 production lines rem. & going)
