Harvey redesigned its document editing agent to iteratively build a Word document in memory using a proprietary OOXML library, replacing a one-shot parallel sub-agent architecture. The new system gives the model tools to compose edits step by step, supports parallel sub-agents with auto-merge, and includes self-review via a diff tool. It ships in the Harvey for Word Add-In and the web Assistant.

## Evidence

Verbatim from https://www.harvey.ai/blog/building-an-agent-for-complex-document-drafting-and-editing:

> We parse the docx file into an in-memory representation via a proprietary library with full OOXML support. We give the model tools to iterate on an in-memory document that are optimized for legal workflows. Each tool has a focused interface, and the model composes them in whatever order makes sense for the task.
