How Fencio prevents this
The tools worked exactly as designed. The agent called them with the wrong arguments, at the wrong time, or more often than it should have, and no layer checked whether the call made sense before it ran.
Fencio validates every tool call against expected intent: argument ranges, recipients, amounts, and call frequency. Calls that fall outside expected bounds, repeat without idempotency, or touch identity and money are held for confirmation.
