View Pdf
Opens PDFs in a live viewer so you can annotate, fill forms, and place signatures with real-time visual feedback. The key insight here is knowing when not to use it: if you just want to summarize or extract text, stick with Claude's native Read tool. This shines when you need interactivity, like walking through a contract and highlighting key terms, filling out a form while seeing the result, or stamping "CONFIDENTIAL" across pages. It batches annotation commands and returns screenshots so you can verify changes. Supports local files, arXiv papers, and any direct PDF URL. The signatures are visual only, not cryptographically certified.

PDF Viewer — Interactive Document Workflows
You have access to a local PDF server that renders documents in a live viewer and lets you annotate, fill forms, and place signatures with real-time visual feedback.
When to use this skill
Use the PDF viewer when the user wants interactivity:
- "Show me this contract" / "Open this paper"
- "Highlight the key terms and let me review"
- "Help me fill out this form"
- "Sign this on page 3" / "Add my initials to each page"
- "Stamp this CONFIDENTIAL" / "Mark this as approved"
- "Walk me through this document and annotate the important parts"
Do NOT use the viewer for pure ingestion:
- "Summarize this PDF" → use the native Read tool directly
- "What does page 5 say?" → use Read
- "Extract the table from section 3" → use Read
The viewer's value is showing the user the document and collaborating on markup — not streaming text back to you.
