dsh-plugin-knowledge-graph: Providing read_graph Code Knowledge Graph Tool for DSH

dsh-plugin-knowledge-graph is an MIT-licensed plugin for DeepSeek Harness (DSH), designed to help agents efficiently understand repository structure by building an in-memory knowledge graph of the codebase, replacing manual file searches. Originating from Luke-Yong/H, this plugin registers the `read_graph` tool and supports parsing for TypeScript/JavaScript as well as Python (with module-level binding). It utilizes node types such as dir, file, and symbol, along with edge types like CONTAINS and EXPORTS, to provide features including directory structure queries, symbol exports, import dependencies, reverse dependencies, and unused import detection. Installation requires Node >=22.19 and specific dependencies, via
