What part of your app is vibe-coded and what was touched by human intelligence?

Hello everyone! I have used codex with gpt5.6 sol, Claude code with opus 5 and fable and tested kimi k3 ( I think their coding agent doesn’t have specific name ) and most of development task is done pretty well . But it still sucks with design ( all vibe coded apps looks similar to me ) and agentic stuff - agent loop , tools and all infra around. And if unique cool design system it’s smth we can postpone ( someone may not agree ) the agent implementation usually is the main product feature. Do you have the same experience guys ?
