dsh-hindsight: Hindsight Memory Bridging Plugin for DeepSeek Harness

dsh-hindsight is an official-grade plugin maintained by Ryu6Zero, designed to provide cross-session memory capabilities for stateless DeepSeek Harness Agents. It does not rely on heavy orchestration layers and functions solely as a standalone HTTP client bridging to the Hindsight REST API. The plugin supports memory retrieval, knowledge graph traversal, proactive memory prompting, and asynchronous operation monitoring via slash commands and six model tools. It features hot configuration, batch deduplication, recall caching, and other capabilities, enabling Agents to access long-term memory and associated decisions, making it ideal for developers who want to add lightweight long-term memory functionality to DSH Agents.
