Vibe coding with Claude Code breaks on complex logic; expert oversight still required
Overview
A senior engineer tried building a game by "vibe coding" with Claude Code (Opus) and found that while simple scaffolds worked, complexity quickly led to bugs and tangled code. When the developer stayed out of the generated code's details, prompts alone couldn't recover, reinforcing that AI works best as an accelerator for engineers who understand and guide the code.

UPDATE Update: Vibe coding with Claude Code (Opus)
A new 2025 Reddit post repeats the 'vibe coding' game experiment using Claude Code with the latest Opus and reports the same failure modes: trivial scaffolds work, but moderate complexity collapses. Compared to our earlier coverage, this update emphasizes that deliberately avoiding reading AI-generated code made recovery via prompts alone impossible, reinforcing limits even on the latest model.
