Today, we release Paper Office, a suite of Python packages that allow agents to manipulate Word, PowerPoint, and Excel files with added safety, correctness and breadth, building on legacy open source packages: python-docx, python-pptx and OpenPyxl. Across five models and 61 tasks, Paper packages plus guidance passed 92.5% of trials , versus 80.7% for upstream packages without skills and 69.5% with Anthropic's comparable Office skills. Agents also wrote code to edit Office file internals directly in just 1.6% of Paper runs , compared with 78.7% without skills and 50.5% with Anthropic skills. We note that basic software, in addition to prompt, skills, and tools, remains an important lever for harness optimization.
