Security checks for vulnerabilities and agentic risk
Overview
This skill transparently searches for coupon codes and tests them only in a promo-code field without completing purchases.
Before installing, understand that the skill can inspect the current checkout page, open hidden tabs to coupon/search sites, fill the promo-code field, and click the code Apply/Redeem button. It is explicit that it must not click Pay, Place Order, Complete Purchase, or fill payment details.
