Across 5 models and 61 tasks, Paper packages plus guidance passed 92.5% of trials, vs 80.7% for the upstream packages alone and 69.5% for Anthropic's Office skills. Agents resorted to raw OOXML editing in only 1.6% of Paper runs, compared to 78.7% without skills and 50.5% with Anthropic skills. The team argues that low agent adoption in consulting, law, and banking stems from tools that silently corrupt formatting, break references, or produce client-unready output. Paper Office keeps the familiar imports and adds cross-run text search, native Word redlines, comment threads, content controls, cross-document composition, and package-level diff saves, refusing unsafe operations instead of quietly breaking files.

Why it matters: Paper Instruments open-sourced a suite of Office file-editing libraries for agents, adding safety checks and broader editing capabilities on top of python-docx and friends. Across 5 models and 61 tasks, they hit 92.5% pass rate — 11.8 points above bare upstream libs and well a...
