I asked again: Are you sure? What about the edge case? It paused. Then fixed the bug. Then gave itself 11/10. That's when I realized: AI code review isn't one thing. It's five different things. And most of us are stuck at Level 1 without even knowing it. Here's the full ladder from trust me bro to actually production ready. Level 1: It Works on My Machine The workflow: Generate code → skim it → ship it → hope for the best. The review: None. Just vibes. You don't know what you don't know. The code works today . But edge cases? Security holes? Performance bottlenecks? You're betting your production environment on luck and the AI's confidence. The tricky part is that this feels fine. The code looks clean. The AI sounded sure. It passed your quick sanity check. So you ship it.…
