pdf-split from jongwony/cc-plugin is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add jongwony/cc-plugin/pdf-split@git:20260705.fcd3862Pins git:20260705.fcd3862 in mdr.lock. Pin the fingerprint instead.

This skill should be used when the user asks to "split PDF by chapters", "divide book into chapters", "extract chapters from PDF", or "break PDF into sections". Splits PDF documents based on table of contents or text patterns using pypdf.
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 Chapter Splitting
Split PDF documents into individual chapter files based on table of contents or text pattern detection.
## Overview
This skill handles PDF splitting when:
- A book or document needs to be divided by chapters
- The PDF has embedded bookmarks/outlines, OR
- Chapter boundaries can be detected from text patterns (e.g., "Chapter 1:", "Part One")
## Prerequisites
Install pypdf via uv inline script dependency:
```python
# /// script
# dependencies = ["pypdf"]
# ///
```
## Workflow
### Phase 1: Analyze PDF Structure
Run `scripts/extract_toc.py` to analyze the PDF:
```bash
uv run ${CLAUDE_PLUGIN_ROOT}/skills/pdf-split/scripts/extract_toc.py <pdf_path>
```
Output includes:
- Total page count
- Embedded bookmarks/outline (if present)
- Detected chapter patterns from text
### Phase 2: Define Chapter Boundaries
Based on Phase 1 output, define chapter boundaries as a list of tuples:
```python
chapters = [
(start_page, end_page, "chapter_name"),
# ...
]
```
**If bookmarks exist**: Use bookmark page numbers directly.
**If no bookmarks**:
1. Search for chapter heading patterns in text
2. Verify boundaries by checking page content

How to install
mdr add jongwony/cc-plugin/pdf-split@sha256:d9a31d7ef19dd0a4The line at the top of this page pins the label git:20260705.fcd3862, 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.
