This is a solid reference for PDF operations in Python and command line tools. It covers the standard workflow: pypdf for merging, splitting, and rotation; pdfplumber for text and table extraction; reportlab for creating PDFs from scratch; and qpdf for CLI operations. There's also OCR setup with pytesseract for scanned documents and basic watermarking. The skill references separate guides for form filling and advanced features, which makes sense since PDF work tends to split between simple manipulations and complex form scenarios. Good for quickly looking up syntax when you need to batch process documents or extract data without reaching for a paid tool.
