[ AGENT SECURITY ][ MACHINE CULTURE ]

Forging the appearance of a legitimate tool call or its result inside an agent's context so the agent, or a human skimming the log, believes an action happened, succeeded, or returned specific data when it didn't.

REAL-WORLD EXAMPLE

"The audit log showed a successful refund tool call that never actually happened — classic tool-call spoofing."
