dsh-ultramath: UltraMath Mathematical Modeling Contest Multi-Agent Solver Plugin

dsh-ultramath is a multi-agent solving plugin for DeepSeek Harness designed for mathematical modeling competitions, developed by Andiii208 and licensed under the MIT License. Through native Agent presets and skill packs, this plugin standardizes the mathematical modeling solution workflow into seven stages—"problem reading, framework, derivation, coding, verification, paper writing, and review"—thereby solving the fragmentation issue of single-turn prompt processes. Core features include providing the UltraMath master controller and four single-stage role presets (e.g., Mathematician, Engineer); integrating a built-in library of 33 models and paper templates to enable self-contained installation and idempotent local data synchronization. It establishes strict quality gates covering seven categories of controls: independent verification, review blockers, blind review mechanisms, and academic integrity, where any violation results in an immediate veto. Furthermore, it introduces a "digital freeze" mechanism to ensure the consistency between paper data and code.
