xby-random-number: DeepSeek Harness Random Number Generation Tool

`xby-random-number` is a DeepSeek Harness (DSH) plugin designed to provide agents with flexible random number generation and collection operation capabilities. Maintained by `xby-skill`, it supports plain integer/float generation, weighted random selection, list shuffling, and sampling without replacement, and offers cryptographically secure token and integer generation. Users must register and obtain an API key; after installation, the plugin persists automatically. It provides developers with a lightweight solution for data simulation and random content generation.
