This article reminds me of what I encountered.

In my case, instead of a Ruby program, I asked for an outliner application similar to Workflowy with clickable bullets to be implemented in CodeMirror v6. It understands what "outliner" means and can put "clickable bullets" in the right context. However, while it gives "plausible" answers, they are all wrong. Wrong API version (often the examples use the pre-v5 version of CodeMirror). Often confuses CodeMirror with Prosemirror. Imports non-existent CodeMirror packages that are clearly imaginary, and has considerable difficulty explaining them when asked. It completely doesn't understand the concept of Decoration objects. And many other problems associated with delivering uninterpretable code.

I had better luck with Cody, who is more familiar with CodeMirror's latest API.
