ChatGPT Web PDF Review Skill
---
name: pdfs
description: Reliable, workflow-driven PDF processing: render → verify → operate → re-render/verify, covering reading, inspection, extraction, editing, forms, OCR, redaction, conversion, and diffing. Prefer authoring in DOCX or PPTX (then converting to PDF) for text-heavy docs or slide-like layouts; use ReportLab here for programmatic PDF generation.
