dsh-code-intel: Symbol-Aware Code Indexing and Hybrid Search for DeepSeek Harness

The DeepSeek Harness plugin dsh-code-intel is designed to address insufficient understanding of local codebases by agents. It supports multilingual code retrieval and outline parsing for TypeScript, JavaScript, Python, and more through symbol-aware indexing, hybrid search, and SQLite persistence. The plugin uses an asynchronous indexing mechanism; on first use, task completion must be awaited via a Job ID. It defaults to offline lexical mode and supports file system watching; to enable hybrid search, configure an OpenAI-compatible embeddings endpoint. Installation requires DSH version >=0.1.0-rc.6 and Node 22+, with secure data privacy.
