DeepSeek Harness Plugin: searchsieve — Search Result Coverage Assessment Tool

The DeepSeek Harness plugin `searchsieve` is designed to address the challenge of quantifying search result quality in RAG scenarios. It provides core metrics such as retention ratio and answer completeness, and performs semantic analysis and evaluation of search results. Using a pure rule-based algorithm, it runs with zero model overhead and requires no API Key, while being optimized for Chinese environments. To install it, run `dsh plugin add search-sieve` and restart after installation. The plugin validates information points through the `expectedPoints` parameter and returns the selected ratio, uncovered information, and follow-up search suggestions. On Windows, it can be used with `dsh.cmd` or `npm.cmd`.
