What It Is

A PRD generation skill that works by synthesis, not interview. Instead of asking you a list of questions, it listens to whatever context you’ve already built up in your AI conversation — discussion about a feature, tradeoffs you’ve explored, constraints you’ve mentioned — and turns that into a structured product requirements document with sections for problem statement, process, deep modules, and test seams. It then publishes the result to your issue tracker with a triage label.

What It Is + Verdict

DOCX is Anthropic’s Word document skill for creating, reading, and editing .docx files in Claude Code. It handles the full feature set — tables of contents, headings, tables, images, page numbers, and tracked changes — producing documents that open correctly in Microsoft Word and Google Docs.

The One Thing That Matters

Word documents are XML packages under the hood, and malformed XML produces corrupted files. This skill knows the correct schema and produces valid output consistently. It handles real document features that naive approaches get wrong: proper heading styles for TOC generation, image embedding with correct relationships, and tracked changes that actually display in Word’s review mode.

What It Is + Verdict

PDF is Anthropic’s document processing skill for working with PDF files in Claude Code. It handles reading text content, generating new PDFs, and modifying existing documents — covering the full PDF workflow without leaving your terminal.

The One Thing That Matters

PDF generation from an AI agent is notoriously hard because PDF is a visual format built from low-level drawing primitives. This skill abstracts that complexity — you describe what the document should look like, and Claude produces correctly formatted PDF output. For reading, it extracts text content that Claude can analyze, summarize, or transform.

PPTX is Anthropic’s presentation skill that generates PowerPoint files from Claude Code. It produces slides with proper layouts, images, and formatting — opening correctly in PowerPoint, Google Slides, and Keynote.

The One Thing That Matters

Good presentations are visual, and this skill generates slide content that includes images and diagrams, not just text placeholders. It understands slide layouts, master templates, and content placement. The output is usable as-is for internal presentations or as a strong first draft for client-facing decks.

XLSX is Anthropic’s spreadsheet skill that creates and edits Excel files from Claude Code. It handles formulas, cell formatting, multiple worksheets, and data layout — producing files that open correctly in Excel, Google Sheets, and LibreOffice Calc.

The One Thing That Matters

The skill handles formulas correctly, not just static values. You can describe a calculation — “add a column that is tax plus shipping” — and it generates the correct Excel formula in the right cell. This means the output spreadsheet is alive: recipients can change inputs and see results update automatically.
