What you get

One package covers the entire document lifecycle — create → read → extract → convert → secure → sign → audit — with honest fidelity reporting (rich | clean | lossy) and proactive next_steps guidance on every creation tool.

• Create — Word / Excel / PPTX / PDF from templates or declarative blocks; corporate themes, logos, watermarks, premium editorial design mode
• Read & extract — structured Markdown/JSON for RAG (read_office, pdf_extract_structured) + embedded images as base64 for multimodal agents
• Convert — PDF ↔ Office ↔ CSV bidirectionally with explicit fidelity warnings
• Secure — irreversible redaction (pdf_redact), metadata scrubbing (scrub_metadata), password encryption (protect_office), form flattening for archival compliance
• Sign & audit — real PAdES signatures (sign_pdf) + cryptographic verification (verify_pdf_signature), honest document diffing (document_diff)
• Productivity — mail merge (mail_merge), native Excel pivots (add_pivot), native PPTX charts, multi-chapter books with auto TOC (create_book)
• Onboarding — owi doctor environment diagnostics with per-OS install hints; packaged skills installable via owi skill install

Efficiency (measured)

~2550 tokens/turn across 29 specialized tools vs ~6400 for a typical 47-tool CRUD suite — less bloat, more stable agents, lower cost. Measured, not claimed.
