Fill PDF forms, annotate or redact a PDF, or add, remove or rotate pages.

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 Forms, Notes, Redaction and Pages

Changes to an existing PDF, made with scripts. Merging, splitting, creating, watermarking and encrypting are in the `pdf` skill; reading a PDF is `read_file`.

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

- **Python libraries (always present):** `pypdf`, `pdfplumber`, `pypdfium2`, `Pillow`.
- **CLI tools (present on current sandbox images):** `pdftoppm` (poppler-utils), `qpdf`, `pdftk`. If one returns `not found`, use the pypdf way on this page rather than trying to install it.

## Fill in a form

Follow FORMS.md, step by step and in order. It checks whether the PDF has fillable fields, then fills them, or writes the answers onto a flat form as annotations, with the scripts in `scripts/`.

## Add a note or text to a page

```python
from pypdf import PdfWriter
from pypdf.annotations import FreeText, Text

writer = PdfWriter(clone_from="input.pdf")
# A rect is (left, bottom, right, top) in PDF points, from the page's bottom-left corner.
writer.add_annotation(page_number=0, annotation=Text(rect=(50, 742, 70, 762), text="Check this total"))  # a comment icon
…

How to install

The exact contents, by fingerprint
mdr add invergent-ai/surogates/pdf-forms@sha256:533d24a853d174e0

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.
