Open PDF

Display a PDF document in the live viewer. Use this when the user wants to see a document — not just extract its text.

Instructions

1. If the user provides a URL or file path, call display_pdf with it
2. If no path given, call list_pdfs first to show available documents
3. After displaying, offer next steps based on the document type:
   • Contract / report → "Want me to highlight key sections or add review notes?"
   • Form → "This has fillable fields — shall I help you fill it?"
   • Academic paper → "Shall I walk through and annotate the key findings?"

Supported Sources

• Local files (paths or drag-and-drop into your working directory)
• arXiv (arxiv.org/abs/... auto-converts to PDF URL)
• Any direct HTTPS PDF URL (use the PDF link, not a landing page)

When NOT to use this

If the user just wants a summary or text extraction, do not open the viewer — use Claude's native Read tool on the PDF path instead. The viewer is for interactive, visual workflows.
