I don't want to be cynical, but maybe spending hours every day using Claude has made some of us particularly attuned to picking this up. For some reason as soon as I read "The trap was in app/test/index.js," I instantly knew it was Claude. It's too bad, because there will obviously be some false positives, but it makes me immediately disregard the author.
I sometimes use the Claude app with text to speech enabled. It’s got a quite distinctive voice/tempo combo when it’s outputting speech.
Whenever I see a typical Claude-tell in writing, my internal reading voice switches automatically from my internal monologue’s voice into Claude’s voice for the rest of the piece.
