This handles Word document creation, editing, and analysis through a combination of pandoc, docx-js, and a custom Python OOXML library. The real value is in the redlining workflow, which converts docs to markdown for planning changes, then implements them as proper tracked changes in the XML with batch processing and minimal edit patterns. If you're creating docs from scratch, it uses docx-js. For reading content, it leans on pandoc. For edits, especially on someone else's document or anything requiring professional review trails, it unpacks the DOCX, manipulates the XML directly with helper scripts, and repacks it. The batching strategy and emphasis on preserving RSIDs shows this was built for real document collaboration workflows, not just text replacement.
