adeu

This Skill addresses the challenge where AI models (like Claude and GPT) struggle to directly and losslessly edit and review complex Microsoft Word documents. In practical work—whether drafting technical documentation, reviewing contract content, or modifying course materials—developers, legal professionals, and content creators often need AI's suggested edits to be presented in Word's "Track Changes" mode. However, traditional libraries tend to corrupt the original formatting and complex structure. Adeu, as an MCP server, acts as an intelligent translation layer between LLMs and Word.

Usage is straightforward: you can install it as an MCP server via the Claude Code plugin marketplace, using the npx command, or with the uvx tool. Afterwards, when you ask an AI assistant (like Claude) to edit a Word document, it will automatically invoke Adeu. Adeu converts the .docx file into an LLM-friendly CriticMarkup format. After the AI makes edits at the Markdown level, Adeu precisely applies those changes back to the original document, perfectly preserving all formatting and comments, and presenting them as "tracked changes."

It is particularly well-suited for teams or individuals who frequently handle Word documents, especially those already using AI assistants like Claude or Cursor for content creation, contract review, or technical writing. Adeu is an ideal tool for product managers drafting requirement documents, legal professionals reviewing contracts, academic researchers revising papers, and any scenario requiring seamless integration of AI's text editing capabilities into existing Word workflows.

We recommend using this tool uniformly for team collaboration on document reviews or when a complete edit history needs to be preserved. Note that it primarily handles text content and structure; editing of extremely complex graphics, charts, or macros may be limited, and it requires the Word document itself to be in a valid .docx format.
