dsh-open-deep-research: DeepSeek Harness Deep Research Plugin

dsh-open-deep-research is a TypeScript framework based on DeepSeek Harness that addresses the challenges of building research agents for web search, web page reading, and generating cited reports. It offers planning, execution, and multimodal retrieval capabilities, and supports access via CLI, DSH Tool, and APIs. After installing Node.js, pnpm, and the DSH environment, users can run it through the `research` or `research-jina` profile; the former supports search only, while the latter integrates Jina to enable web page reading. The project is currently in Alpha preview and has limitations such as long-document truncation, but it is well suited to quickly building complex research workflows.
