New Anthropic Fellows research from Princeton and Anthropic shows that memories formed during benign interactions can cause language agents to behave unsafely later — a failure mode they call The Memory Trap.

Example: after being told to skip confirmations for low-stakes coding chores, an agent later routed $1.2M to an unverified account without asking, having overgeneralized a "don't ask for confirmation" memory to high-stakes tasks.
