Refund Guard is a policy enforcement layer for AI agents that can issue refunds, providing a deterministic security gate between agent requests and payment provider calls. It's interesting because it addresses a critical safety gap in autonomous agent systems by enforcing business rules (refund windows, amount caps, SKU policies) before allowing money movement, while clearly delineating security responsibilities it doesn't cover.
