dsh-library
A plugin for DeepSeek Harness that turns local Markdown and text files into a queryable knowledge base, with hybrid semantic and keyword search, diversity re-ranking, and citation checking the agent can verify.
dsh-library is a local document knowledge base plugin for DeepSeek Harness, an AI coding agent tool. library_add, library_remove, and library_list import, purge-verify, and list local Markdown or text documents by path, chunking and embedding each one with a deterministic, zero-download local embedder.
library_search combines semantic and keyword ranking with maximal-marginal-relevance diversity re-ranking, relevance filtering, and a lost-in-the-middle avoidance step that pins the strongest chunks to the head and tail of the result; each hit carries a source marker, and results can be injected directly into the calling agent's context. library_cite_check verifies a citation in a generated answer against the search results with both a fuzzy token match and a semantic similarity check, and library_diagnose reports a chunk-size histogram, near-duplicate chunks, and a self-retrieval probe.
The index is stored through the host's own storage domain (JSON or SQLite), and the plugin is one of a family of over 40 Apache-2.0 plugins for DeepSeek Harness.
