dsh-office-tool: Office Document Plugin for DeepSeek Harness

dsh-office-tool is an MIT-licensed plugin for DeepSeek Harness (DSH) designed to provide agents with the capabilities to create, read, query, and edit .docx, .xlsx, and .pptx documents. It executes operations by invoking the OfficeCLI binary, removing the need to install Microsoft Office. The plugin exposes nine structured tools to the model, covering document creation, element CRUD operations, batch operations, and raw command passthrough, while supporting structured JSON responses to optimize error handling. In a web environment, when paired with the dsh-better-sidebar plugin, it offers real-time document previews in the sidebar; in a headless mode without a Web UI, all tools remain fully accessible.
