pdf-ocr-audit

Audit PDF files to determine whether OCR (optical character recognition) is needed to make them fully text-searchable. Use this skill whenever the user asks about PDF searchability, OCR status, whether PDFs have embedded text, which PDFs are scans, or wants to audit/inventory a folder of PDFs for text extraction readiness. Also triggers for: "which PDFs need OCR", "are my PDFs searchable", "do these PDFs have text layers", "audit my PDFs", "find scanned PDFs".
