dsh-gcd: Greatest Common Divisor Calculation Tool

dsh-gcd is a pure Node.js plugin designed for DeepSeek Harness (DSH) workflows, used to calculate the greatest common divisor of two numbers. It does not depend on the network, integrates through the Cordis framework, and is licensed under the MIT License. Once installed, the plugin can be invoked directly within a session, providing precise mathematical computation capabilities, and is suitable for workflow scenarios that prioritize a minimal toolchain or deterministic results. Since it runs with the current process permissions, it is recommended to review the source code before use.
