dsh-switchman: DeepSeek Harness Context Management and Scheduling Plugin

dsh-switchman is a plugin for DeepSeek Harness designed to address context bloat in long sessions. It manages context through watermark control (soft, hard, and forced thresholds) and six scheduling pools (economy, mechanical, main model, among others), transforming the main model from an executor into a scheduler that allocates tasks effectively to reduce costs. The plugin supports agent-team mode, hierarchical validation, and multilingual interfaces, significantly improving the stability and efficiency of autonomous coding workflows.
