dsh-llmwiki: A Local Markdown Wiki for DeepSeek Harness

dsh-llmwiki is a local-first Markdown Wiki plugin for DeepSeek Harness (DSH), designed to provide a deterministic storage and retrieval solution. The plugin leverages the local file system, SHA-256 hashing, and the BM25 algorithm to ensure that data is immutable, privacy-safe, and free of external dependencies. Users must explicitly activate the plugin via a patch and configure optional parameters to manage the Wiki root directory and file size limits. Once installed, the plugin can be used by agents as services, tools, and commands, making it suitable for development scenarios that require offline operation.
