This is very cool. I looked at the Claude.md he was generating and it is basically all of Claude's failure modes in one file. I can think of a few reasons why Anthropic would not want this information out in the open or for someone to systematically collate all the data into one file.
i read the related parts of the linked file in the repo, and it took me a while to find your comment here again to reply to. Are you saying that the failure modes of claude with "coding" webapps or whatever OP was doing? i originally thought it might have meant like... jailbreak. But having read it, i assume you meant the former, as we both read the same thing and it seemed like a series of admonitions to the LLM, written by the LLM (with some spice added by OP? like "YOU ARE WRONG") and i couldn't find anything that would warrant a ban, you know?
