Read, extract (text/tables), create, merge/split/rotate, watermark, encrypt,.
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
Work PDFs in the sandbox with preinstalled Python libs. Pick the library by task:
- **Extract** text/tables/layout/word-coordinates → `pdfplumber`; quick raw text or page ops → `pypdf`.
- **Merge / split / rotate / crop / watermark / encrypt / metadata** → `pypdf`.
- **Fill forms** → `pypdf` (fillable AcroForm fields) or annotation overlay (flat forms).
- **Create from scratch** → `reportlab`.
Use `exec` with complete Python source (`language: python`). Prefer creating,
reopening, and validating the PDF in one call; later calls can revise the same
relative filename. Follow the turn's **User workspace** instructions for
locating inputs, output boundaries, and presenting the finished file.
Preserve an explicitly requested quantity (such as 500 words) and verify the count in the output before finishing. If execution fails or the artifact is missing, diagnose stderr/root cause and change strategy; do not retry identical code or reduce the requested scope without asking.
## Extract text and tables (pdfplumber)
```python
import pdfplumber
with pdfplumber.open("in.pdf") as pdf:
for i, page in enumerate(pdf.pages, 1):
print(f"--- page {i} ---")
…Read the whole file at its exact version.
How to install
mdr add hkuds/deeptutor/pdf@sha256:c950efb9d180879bThe line at the top of this page pins the label git:20260906.04040a2, 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.
