If I see an LLM having trouble with a library, I can feed its transcript into another agent and ask for actionable feedback on how to make the library easier to use. Which of course gets fed into a third agent to implement. It works really well for me. Nothing more satisfying than a satisfied customer.

I've done something similar. I ask agents to use CLIs, then I give them an "exit survey" on their experience along with feedback on improvements. Feels pretty meta.
