> Agents load skills on demand to produce finished PDFs, Word documents, Excel workbooks, slide decks, on-brand designs, and email that renders everywhere.

Ask an agent for a deliverable and you used to get Markdown or a hand-built HTML file. Agents now have skills: packaged instructions plus the tools to produce a specific kind of output, shared across chat, the workflow builder, and agent workflow runs.

### The skills

- **PDF:** extract text and tables, merge, split, watermark, run OCR on scanned pages, and create new PDFs.
- **Word, Excel, PowerPoint:** create and read .docx, .xlsx (with formulas and styling), and .pptx files, and convert any of them to PDF.
- **Brand guidelines:** pull a company's palette, fonts, and logo from its website and apply them consistently.
- **Email design:** HTML email that holds up in Outlook, dark mode, and Gmail's 102 KB clipping limit.

### How it works

- **Loaded on demand.** Agents see a one-line description of each skill and load the full instructions only when a task needs them, which keeps prompts short and cacheable.
- **Ready to run.** The sandbox ships with the document toolchain (pypdf, python-docx, openpyxl, python-pptx, pandas, LibreOffice, Tesseract) and 48 fonts preinstalled, so the first PDF in a run doesn't wait on installs.
- **Inline previews.** Files and images an agent creates render right in the chat.
