DeepSeek Harness Web Search Plugin: Source-Traceable Brave / Tavily Search and Extraction

The DeepSeek Harness web search plugin packages the real-time search and URL extraction capabilities of Brave and Tavily into a native plugin. It provides a transparent and traceable search experience, with tools such as `web_search`, `web_extract`, `provider_status`, and `health_check`. At installation, API keys must be configured via environment variables. The plugin reads keys only from the environment and does not write them to configuration files, aiming to provide stable tool contracts and source traces for research workflows.

dsh-tavily-web-search: Tavily Search Provider for DeepSeek Harness web_search integration

# Introduction In the DSH (DeepSeek Harness) system where "everything is a plugin," `web_search` is one of the most commonly used tools for agents to access the internet. However, the completeness of search results depends on the underlying search provider: if only a string of links is obtained, the model still has to crawl the web pages and organize them, consuming more time and context. `dsh-tavily-web-search` focuses on a specific task: connecting the DSH search provider to Tavily's REST API, allowing `web_search` to directly return a list of links, summary answers, and structured citation sources. The following sections introduce its functionality, installation, and configuration methods. ## What is it? `dsh-tavily-web-search` is created by paul-

dsh-web-search-tavily: Switch DSH's web_search to Tavily, Usable Without an API Key

Default parameters include basic search depth and 5
