pdf-text-extraction from cxcscmu/skilllearnbench is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add cxcscmu/skilllearnbench/pdf-text-extraction@git:20260424.d50cf5aPins git:20260424.d50cf5a in mdr.lock. Pin the fingerprint instead.

Extract text from PDF files using pdfminer or PyMuPDF to read titles and abstracts for classification.
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 Text Extraction Skill
## Overview
When paper filenames don't contain enough information, extract text from the first page of PDFs to get titles and abstracts for classification.
## Installation
```bash
pip install pdfminer.six # Pure Python, reliable
pip install pymupdf # Faster, aka fitz
pip install pypdf2 # Lightweight alternative
```
## Using pdfminer.six (Recommended for accuracy)
```python
from pdfminer.high_level import extract_text
def get_first_page_text(pdf_path, max_chars=2000):
"""Extract text from first page only for fast classification."""
try:
text = extract_text(pdf_path, maxpages=1)
return text[:max_chars]
except Exception as e:
return ""
```
## Using PyMuPDF (Recommended for speed)
```python
import fitz # PyMuPDF
def get_first_page_text(pdf_path, max_chars=2000):
try:
doc = fitz.open(pdf_path)
text = doc[0].get_text()
doc.close()
return text[:max_chars]
except Exception as e:
return ""
```
## Extracting Title from PDF
```python
def extract_title(pdf_path):
"""Try metadata first, then text extraction."""
try:
doc = fitz.open(pdf_path)

How to install
mdr add cxcscmu/skilllearnbench/pdf-text-extraction@sha256:f9174a6661d9bf96The line at the top of this page pins the label git:20260424.d50cf5a, 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.
