Create PDFs, or merge, split, watermark, encrypt/decrypt, extract tables/images from, or OCR existing ones.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# PDF Processing Guide

## Overview

This guide covers PDF **transformations** — merging, splitting, creating, watermarking, encrypting, extracting images, and OCRing scanned PDFs. To fill, annotate, redact or rotate: office_edit where the chat has it, else the pdf-forms skill. **Reading text/tables is handled by `read_file` directly; do NOT use this skill for plain reading.** See REFERENCE.md for advanced library usage.

**Dependencies are pre-installed in the sandbox image — do NOT `pip install` or `npm install` anything.** Just import or invoke directly.

- **Python libraries (always present):** `pypdf`, `pdfplumber`, `pypdfium2`, `reportlab`, `pytesseract`, `pdf2image`, `Pillow`, `pandas`, `numpy`.
- **JavaScript libraries (always present):** `pdf-lib`, `pdfjs-dist`.
- **CLI tools (present on current sandbox images):** `pdftotext` / `pdftoppm` / `pdfimages` (poppler-utils), `qpdf`, `pdftk`, `pandoc`, `tesseract`. Older sandbox images may be missing some of these — if a CLI tool returns `not found`, fall back to the equivalent Python library on this page rather than trying to install it.

## Reading PDF text — use `read_file`

How to install

The exact contents, by fingerprint
mdr add invergent-ai/surogates/pdf@sha256:c615c4188b708caa

The line at the top of this page pins the label git:20261104.c3eaa01, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
