I have a process I wrote that accepts commands on a socket. At one point Claude suggested testing it. I pretty much echoed back what Claude suggested and got blocked. All I could think was a regex matching “test” and “port” and it downgraded me. I switched back to Fable with slight rewording and was able to continue. This was for code running on my box in a Claude project folder where Claude saw me write the code. Anthropic has put zero thought into this.
