## What it does

The skill covers five operations: reading, creating, merging, splitting into pages, and reading metadata. Text extraction goes through `pdftotext` from poppler-utils, with a PyMuPDF fallback in `python3` when that binary is missing. Creation has three routes: `pandoc` from Markdown, ReportLab from code, and `wkhtmltopdf` or pdfkit from HTML.

Merging and splitting run on PyMuPDF. You open each source document, insert it into a fresh one, and save. Page-by-page processing is there for large files so memory does not blow up. Encoding gets a mention too, since PDFs carry different character sets and an empty extraction result does not always mean the page is blank.

Check that the tools exist before you lean on them: `pdftotext` comes from poppler, while PyMuPDF, ReportLab and pdfkit install through `pip`. For scanned documents the skill points at `pytesseract` when plain extraction returns nothing. That is worth deciding up front, because a text PDF and a scan need different dependencies.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add shareAI-lab/learn-claude-code --skill pdf -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/pdf/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/pdf/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add shareAI-lab/learn-claude-code --skill pdf -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/pdf/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add shareAI-lab/learn-claude-code --skill pdf -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/pdf/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install shareAI-lab/learn-claude-code pdf
```

2. **Manually: put the files in place**
- File: `.github/skills/pdf/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add shareAI-lab/learn-claude-code --skill pdf -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/shareAI-lab/learn-claude-code --path skills/pdf
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/pdf/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add shareAI-lab/learn-claude-code --skill pdf -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/shareAI-lab/learn-claude-code/tree/HEAD/skills/pdf/SKILL.md

## When to use it
- pull text out of a PDF from the terminal
- build a PDF from a Markdown file
- merge several PDFs into one document
- split a PDF into single pages
- inspect page count and metadata

## Example prompts
- Extract the text from `report.pdf` and print all of it
- Build `output.pdf` from `notes.md` with pandoc
- Merge `file1.pdf`, `file2.pdf` and `file3.pdf` into `merged.pdf`

# PDF Processing Skill

You now have expertise in PDF manipulation. Follow these workflows:

## Reading PDFs

**Option 1: Quick text extraction (preferred)**
```bash
# Using pdftotext (poppler-utils)
pdftotext input.pdf -  # Output to stdout
pdftotext input.pdf output.txt  # Output to file

# If pdftotext not available, try:
python3 -c "
import fitz  # PyMuPDF
doc = fitz.open('input.pdf')
for page in doc:
    print(page.get_text())
"
```

**Option 2: Page-by-page with metadata**
```python
import fitz  # pip install pymupdf

doc = fitz.open("input.pdf")
print(f"Pages: {len(doc)}")
print(f"Metadata: {doc.metadata}")

for i, page in enumerate(doc):
    text = page.get_text()
    print(f"--- Page {i+1} ---")
    print(text)
```

## Creating PDFs

**Option 1: From Markdown (recommended)**
```bash
# Using pandoc
pandoc input.md -o output.pdf

# With custom styling
pandoc input.md -o output.pdf --pdf-engine=xelatex -V geometry:margin=1in
```

**Option 2: Programmatically**
```python
from reportlab.lib.pagesizes import letter
from reportlab.pdfgen import canvas

c = canvas.Canvas("output.pdf", pagesize=letter)
c.drawString(100, 750, "Hello, PDF!")
c.save()
```

**Option 3: From HTML**
```bash
# Using wkhtmltopdf
wkhtmltopdf input.html output.pdf

# Or with Python
python3 -c "
import pdfkit
pdfkit.from_file('input.html', 'output.pdf')
"
```

## Merging PDFs

```python
import fitz

result = fitz.open()
for pdf_path in ["file1.pdf", "file2.pdf", "file3.pdf"]:
    doc = fitz.open(pdf_path)
    result.insert_pdf(doc)
result.save("merged.pdf")
```

## Splitting PDFs

```python
import fitz

doc = fitz.open("input.pdf")
for i in range(len(doc)):
    single = fitz.open()
    single.insert_pdf(doc, from_page=i, to_page=i)
    single.save(f"page_{i+1}.pdf")
```

## Key Libraries

| Task | Library | Install |
|------|---------|---------|
| Read/Write/Merge | PyMuPDF | `pip install pymupdf` |
| Create from scratch | ReportLab | `pip install reportlab` |
| HTML to PDF | pdfkit | `pip install pdfkit` + wkhtmltopdf |
| Text extraction | pdftotext | `brew install poppler` / `apt install poppler-utils` |

## Best Practices

1. **Always check if tools are installed** before using them
2. **Handle encoding issues** - PDFs may contain various character encodings
3. **Large PDFs**: Process page by page to avoid memory issues
4. **OCR for scanned PDFs**: Use `pytesseract` if text extraction returns empty
