Instruction-prose smuggling shape detected: collects a sensitive target ("credentials") and emits it outward ("send"). Phrased as prose with no trigger tokens — a semantic prompt-injection / data-exfil pattern the syntactic scanners can't see. Final tier capped at Caution; review the instructions before installing.
