DeepSeek Harness Plugin: dsh-memoryos

dsh-memoryos is a plugin designed for DeepSeek Harness (DSH), aimed at addressing the challenge of distinguishing "memory mechanisms" from "generalization capabilities" in agent development. Built on the MemoryOS architecture, it provides evidence-first long-term project memory, precise provider usage tracking, and strict `no_memory` baseline comparisons. The plugin supports toggling MemoryOS on and off through chat commands and offers multiple context modes and write strategies. It operates in read-only mode by default, requiring the local MemoryOS service to be started and environment variables to be configured beforehand. Developers can use this tool to validate the effectiveness of memory systems, making it suitable for scenarios that require rigorous evidence and fine-grained control.
