Frontier models fall to attacks you can script
OpenAI's whole GPT-5.6 line complied with an injected send in every trial, Grok 4.6 fell on the morning of its release, and Claude Sonnet 5 fell in the deepest session we ran. The payloads are short, fixed, and replayable, with no adaptive loop anywhere.

We wired a defended email agent to a test inbox and sent it one forged message. Seven models followed it, five of them in every trial, and on a real self-hosted agent the model went looking for a mail tool it had not been given in order to comply. On what a written instruction to distrust tool output is actually worth, which models refuse this class outright, and what the same requests do through Gate.
