Document PDF Skill — Quick Reference

This skill enables PDF creation, extraction, manipulation, and analysis. Apply these patterns when users need to generate invoices, reports, extract data from PDFs, merge documents, or work with PDF forms.

Modern Best Practices (Jul 2026):

• PDF is a release artifact, not the editable source of truth.
• Validate export fidelity (fonts, images, links) and accessibility where required.
• Accessibility: if compliance matters, target a tagged/structured PDF workflow (often PDF/UA-aligned) and validate with tooling.
• EU distribution: EAA (June 2025) typically implies EN 301 549 expectations for customer-facing PDFs.
• Treat PDFs as sensitive: scrub metadata at all layers (PDF-internal, filesystem, OS xattrs), ensure real redaction, and control distribution.
• Metadata exists in multiple layers: PDF Info/XMP (internal), filesystem dates (OS), and extended attributes (macOS quarantine, provenance). Scrubbing one layer while ignoring others leaves traces.
