DSH-Office is a DeepSeek Harness plugin that generates and edits PPTX, DOCX, XLSX, and PDF files through a local zagens-office engine. It exposes office_schema to fetch the JSON contract, office_write to create documents, office_edit to apply operations to existing files, and office_read to verify results. Call office_schema before writing to learn the field structure. If the engine is missing, the model auto-downloads it to ~/.zagens-pro/bin; pin to a commit-sha for reproducible installs.
