What problem does it solve? Producing polished Word documents programmatically is error-prone: formatting gets lost when extracting text, markdown-to-docx conversions look mediocre, and OpenXML's strict element ordering causes corrupt files. This Skill routes every .docx task to the right toolchain and validates the output automatically. ## Core Features & Use Cases - Three-route workflow: WIR engine for editing existing documents (comments, tracked changes, format-preserving edits), C# + OpenXML SDK for building documents from scratch, and an md2docx pipeline for converting agent-produced Markdown with citations into footnoted Word files. - Rich document elements: native Word charts (pie, bar, line), OMML math equations, tables, footnotes, TOC field codes, headers/footers, and generated cover backgrounds via Playwright + SVG. - Built-in validation: the build pipeline compiles, auto-fixes XML element order, and runs OpenXML plus business-rule checks before delivery. - Use Case: Ask for a quarterly business report in Chinese with a cover page, TOC, charts, and page numbers — the Skill generates a validated, consistently styled .docx ready to open in Word. ## Quick Start Create a Word document report on renewable energy trends with a cover page, table of contents, and a bar chart.
