dsh-sum-of-divisors: Sum of Divisors

The “dsh-sum-of-divisors” plugin for DeepSeek Harness (DSH) provides developers with mathematical computation capabilities that do not rely on network access. Maintained by uckkk and implemented in pure Node.js, it is suitable for offline or restricted network environments. Before use, dependencies such as `@deepseek-ai/cordis` and `@deepseek-ai/dsh-tools` must be installed. The plugin runs with process-level privileges; it is recommended to review its source code and license. It is primarily used for numeric logic processing in agent development, supporting installation via a command and direct invocation within a session.
