Part 1: Goals

⚠️ When to Unzip vs Read

To preserve ANY formatting from the source document, MUST unzip and parse XML.

Read tool returns plain text only — fonts, colors, alignment, borders, styles are lost.

Core Principles

1. Preserve formatting — When editing existing documents, retain original formatting. Clone and modify, never recreate.

2. Correct feature implementation — Comments need multi-file sync. Track Changes need revision marks. Use the right structure.
