Why Do AI Coding Agents Speak Nonsense? Devs Blame RLVF Alignment Issues

Recently, many developers have reported that AI coding tools like Fable and Sol are generating gibberish and nonsensical phrases (e.g., "arming the assumptions-side entry wrappers") during execution.
A developer pointed out that this is a form of "bad alignment." While not catastrophic, it significantly degrades the user experience. They attribute this issue to models being overly optimized or "fried" by Reinforcement Learning from Human Feedback (RLHF/RLVF).
