Our port of Messaging to Compose was clearly not vibe coded as both the parent comment and yours are wrongly portraying it. Experienced developers have been working on overhauling the app for months with a lot of back and forth code review to get the pull requests into shape. We don't have a policy against using AI for assistance as long as the resulting code meets our high standards.

We definitely use frontier AI models with cybersecurity access unlocked for code review. Those often find problems we didn't catch via multiple rounds of human review. The output is filled with hallucinations and incorrect details but an experienced developer can sift through it, identify the real issues it uncovered and get those fixed.

I dunno. If they're using AI, it's well controlled. I don't see a lot of artifacts you usually get from full-on vibe-coding.
