hunting-price-and-coupon-manipulation skillA

hunting-price-and-coupon-manipulation is agent-read markdown (skill) from unboundcompute/security-agent-skills: Hunt for ways a buyer can control the price the server charges: a price, quantity, or line total taken from the client request instead of recomputed server-side from a trusted catalog, a negative or overflowing quantity that drives the total down or wraps it, a discount or coupon that stacks, reuses past its limit, or applies to items it should not, and a total computed on the client and trusted at checkout. Covers e-commerce carts, checkout totals, and promotion engines where the amount charged.
