An AI developer detailed nine critical bugs found in an AI system designed to rewrite its own prompts, highlighting how subtle errors can make a flawed system appear functional. One major issue involved a statistical miscalculation where the system incorrectly promoted prompt edits with a high probability of being random noise due to checking p < 0.95 instead of the correct p < 0.05. Other critical flaws included an A/B testing mechanism that compared a prompt against itself, a scoring system that accepted any non-empty response as valid, and issues with Docker tests, fabricated failure traces, and incorrect prompt delivery. The developer emphasized that the most dangerous bugs are those that produce seemingly correct output, leading to system drift rather than learning. AI
