Lessons from three months of vibe coding (and a complexity score of 53) (opens in new tab)

TL;DR — I spent three months vibe-coding a side project with an AI agent. It felt fast and productive until I opened a file and saw 3000 lines, functions that should have been one helper but were copy-pasted ten times, and a cyclomatic complexity score of 58 in one of them. The agent wasn't the problem. The missing feedback loop was. This is what I should have set up on day one — and what I now consider non-negotiable when working with AI agents. uv run complexipy . --top 10 ./rounds/views.py...
