dsh-coupon-profit: Post-Coupon Gross Profit Calculation Plugin

The DeepSeek Harness plugin dsh-coupon-profit is designed specifically for e-commerce and transactional agents, aiming to address the high maintenance cost of manually writing profit-calculation logic. Maintained by uckkk, it is a networking tool implemented purely in Node.js and can run without a network environment, supporting precise parameter-based calculations and returning detailed gross profit results. Developers can install it with one click via the official command and invoke it directly in sessions. Since the plugin runs with the permissions of the current DSH process, the source code and license should be checked before use.
