Docs & Office skills

10 Docs & Office skills, most installed first. I read every file in each one to see what it can access, and show the security audits from skills.sh. See all skills.

Best for Solo founders who want their agent to make decks, PDFs and spreadsheets

This page lists the Agent Skills I picked for documents and office files: slide decks, PDFs, Word files, spreadsheets, diagrams and explainers. They are sorted by total installs on skills.sh, and I read every skill file by file to rate its access (Low, Medium or High), meaning what it can touch on your machine and accounts.

Start with PowerPoint Decks (PPTX) and Excel Spreadsheets (XLSX) from Anthropic. The first builds and edits slide decks and validates the result. The second keeps live formulas and runs a recalc script to report broken cells. Both come in the same document-skills plugin as PDF and Word Documents (DOCX).

For diagrams, try Diagram Design. It writes one HTML file that matches your brand's palette and fonts.

Questions

How do I install the Anthropic PDF, Word, Excel and PowerPoint skills in Claude Code?

Run /plugin marketplace add anthropics/skills, then /plugin install document-skills@anthropic-agent-skills. That one plugin installs PDF, Word Documents (DOCX), Excel Spreadsheets (XLSX) and PowerPoint Decks (PPTX).

What is the difference between Archify and Diagram Design?

Archify builds standalone HTML diagrams you can click through, links nodes back to source code when you point it at a repo, and can also make one-page explainers. Diagram Design covers 45 diagram types in a calm editorial style, reads your website's palette and fonts once so every diagram matches your brand, and can redraw draw.io, Mermaid or Excalidraw files.

Are the Anthropic document skills open source?

No. The Anthropic skills (PowerPoint Decks (PPTX), PDF, Word Documents (DOCX) and Excel Spreadsheets (XLSX)) have a proprietary, source-available license. Archify, Diagram Design, Anatomy and Scientific Agent Skills are MIT licensed.

What is the best Agent Skill for Excel spreadsheets with working formulas?

Excel Spreadsheets (XLSX) builds and edits spreadsheets with openpyxl and pandas, and it uses live formulas instead of hardcoded numbers. Its bundled recalc script runs LibreOffice to compute every formula and report broken cells.
