Security checks for vulnerabilities and agentic risk

Overview

This skill automates redeeming user-provided prepaid coupon links and includes clear checks to avoid extra payment or accidental redemption.

Install only if you are comfortable letting the agent operate a browser on prepaid coupon links you own. Confirm the intended store and pickup choices before irreversible redemption, stop if the page asks for extra payment, and treat redemption codes and screenshots as sensitive until used.
