A user shared an experience with Fable 5.1 where it refactored an entire codebase—adding 55,000+ new lines and 34 new files in a single call. While the code was modularized and cleaned up beautifully, it was completely non-functional. This highlights the gap between syntactic correctness and functional reliability in current AI coding agents.
