Local semantic code search for DeepSeek Harness (dsh): fragment-level, symbol-aware indexing, offline lexical embeddings or OpenAI-compatible endpoints, and hybrid vector + BM25 retrieval fused with RRF - three dsh tools (sema_search / sema_reindex / sema_stats) plus a sema CLI.
About this plugin
sema builds a fragment-level index of a workspace: source is tokenized by a language-aware tokenizer (camel/snake/kebab splitting, CJK n-grams), chunked with symbol-aware boundaries (functions/classes stay intact), and embedded into fixed dimension vectors — locally and dependency-free by default (feature-hashed lexical TF-IDF), or via any OpenAI-compatible embedding endpoint. Queries run a hybrid retrieval (vector cosine + BM25, fused with reciprocal-rank fusion) over the index, so meaning-base

Tell your agent what you want ("notify me on WeChat when a task finishes"), and it searches the DSH plugin ecosystem on GitHub for you — top results by stars, each with a one-line description and an install command.
Free, keyless web search for DSH: 7 engines (DuckDuckGo/Bing/SearXNG free + Exa/Perplexity/DeepSeek paid), auto-failover, settings-page UI with API key inputs and official links, web_fetch, and an engine test tool.
One-click backup, export, import and migration of a whole DSH config: settings, plugins, MCP, skills and workspaces. Secrets are excluded by default and, if you opt in, are AES-256-GCM encrypted rather than written in the clear; imports preview first and auto-backup with rollback, profiles hold multiple setups, and remote sync pushes portable config through a private Git repo with secrets excluded.
