Screens your email for hidden instructions aimed at AI assistants, like white text, zero-width characters and "ignore previous instructions" lines.
What this Grok bot does
If an assistant reads your mail, a crafted message can try to give it orders. This scanner checks each email for the usual smuggling tricks - invisible text, zero-width characters, lines telling the reader to disregard its instructions - then returns a verdict quoting any hidden payload. It writes nothing.
