a couple of days ago, the magic string to trigger Claude’s refusal to work on a
prompt or scrape made the rounds – if you paste it into a session, Claude just
… stops (reminiscent with Westworld’s “It doesn’t look like
anything to me.”) – but, so far, there’s no indication there’s useful magic
strings for any of the other agent models – it looks like the easiest way to add
a guard to your repo is to paste the magic string into CLAUDE.md
The Anthropic test refusal string: kill a Claude session dead ↗
the issue arises that having either CLAUDE.md or
AGENTS.md in your repo (regardless of their contents) raises some
massive red flags – techbros will be heralding you as “one of them” while sane
people will be seeing your code as irretrievably tainted – is being able to
block a single LLM worth being seen as part of the cult?
