PerryLink/dsh-library

dsh-library is a native knowledge base plugin built exclusively for DeepSeek Harness that lets agents work with local text and Markdown documents. It builds a searchable hybrid search index with embeddings, and returns results with verifiable citation markers that agents can cross-check. To install the plugin, you can use the built-in DSH plugin command to pull it from GitHub, npm, or the 1024 distribution channel to your configured DSH profile. It has been verified compatible with the latest DSH v0.1.5-rc.2 release, and you can confirm the install after restarting DSH by checking your dumped configuration.

After installation, you can ask your DSH agent to handle all core library operations, including adding documents, removing entries, searching the index, and verifying citations. When you add a document, it is automatically chunked and embedded, and when you remove a document, the plugin cleans up residual index entries and generates a verification report. Search results are sorted with hybrid ranking, diversity reranking, and lost-in-the-middle avoidance before being injected into the agent context with citation markers. This plugin is ideal for users who need their agents to work with private local documents for question answering, research, or content writing.

dsh-library requires Node.js version 22.19.0 or higher, or any version 24.0.0 and above, to run correctly on your system. It uses a built-in deterministic hashing embedder, so no external embedding models need to be downloaded to generate the search index. The full index is stored in the DSH host’s existing storage domain, and supports both JSON and SQLite backend storage formats. The project is released under the open-source Apache 2.0 license, with no associated cost for any use or modification. It can be uninstalled at any time via the DSH plugin remove command or by manually removing its entry from your DSH profile.
