xby-dice: DeepSeek Harness Dice Rolling Service

xby-dice is a lightweight plugin for DeepSeek Harness (DSH), designed to provide dice simulation functionality for agents. It allows users to invoke the dice service directly using standard mathematical notation (such as `2d6+3`), simplifying the development of randomization logic. Installation and usage are straightforward, as it can be pulled via the DSH command line. Before use, users need to configure an API key on the Xiaobenyang official website; the key supports persistent storage. The plugin mainly provides two interfaces: setting the API key and executing dice rolls. It is well suited for scenarios involving rule-based games or the introduction of random elements.
