Skills cover document creation (.docx/Google Docs with render-and-verify workflows), spreadsheets (.xlsx/.csv with formulas and charts), PowerPoint/Google Slides decks, PDF generation/inspection via Poppler and reportlab, image generation, charts, interactive learning widgets, and in-conversation visualizations. Why: If you are building workflows on top of ChatGPT Work or evaluating it against other agent platforms, this inventory lets you see exactly which capabilities are built-in versus what you'd need to wire up yourself. The document skill's strict render-and-verify loop (generating page PNGs via render_docx.py before delivery) and the PDF skill's specific toolchain (Poppler, reportlab, pdfplumber, pypdf) tell you what quality bar to expect and whether your use case is already covered. ai-agents chatgpt-work tool-reference codex
