Introduction to the DeepSeek Harness Documentation Tool Plugin

`dsh-tool-doc` is a plugin for DeepSeek Harness (DSH) designed to let Agents process documents directly without invoking external commands via the Shell. It provides three core tools—read, create, and edit—and supports formats such as PDF, DOCX, XLSX, and CSV. Editing operations support text replacement, cell updates, and appending rows, with strict validation mechanisms. Key limitations include DOCX supporting only paragraph-level replacement, PDF/PPTX not supporting in-place editing, and binary format writes not adhering to the sandbox policy. By integrating document operations, the plugin significantly reduces the latency and complexity of document processing for Agents.
