## Overview

The PDF Skill is designed for tasks involving the creation, reading, and reviewing of PDF documents where layout and visual fidelity are crucial. It provides a structured workflow for generating PDFs using Python libraries such as `reportlab` for document creation and `pdfplumber` or `pypdf` for text extraction. Users can visually inspect rendered pages by converting them into PNG format using tools like `pdftoppm`, ensuring high-quality output with consistent typography and layout. This skill is particularly valuable for professionals who require accurate document representation and formatting verification before final delivery, making it essential for fields such as publishing, academia, and technical documentation.

## Summary

### When to use
- Read or review PDF content where layout and visuals matter.
- Create PDFs programmatically with reliable formatting.
- Validate final rendering before delivery.

### Workflow
1. Prefer visual review: render PDF pages to PNGs and inspect them.
   - Use `pdftoppm` if available.
   - If unavailable, install Poppler or ask the user to review the output locally.
2. Use `reportlab` to generate PDFs when creating new documents.
3. Use `pdfplumber` (or `pypdf`) for text extraction and quick checks; do not rely on it for layout fidelity.
4. After each meaningful update, re-render pages and verify alignment, spacing, and legibility.

### Temp and output conventions
- Use `tmp/pdfs/` for intermediate files; delete when done.
- Write final artifacts under `output/pdf/` when working in this repo.
- Keep filenames stable and descriptive.

### Dependencies (install if missing)
Prefer `uv` for dependency management.

Python packages:

```
uv pip install reportlab pdfplumber pypdf
```

If `uv` is unavailable:

```
python3 -m pip install reportlab pdfplumber pypdf
```

System tools (for rendering):

```
# macOS (Homebrew)
brew install poppler

# Ubuntu/Debian
sudo apt-get install -y poppler-utils
```

If installation isn't possible in this environment, tell the user which dependency is missing and how to install it locally.

### Environment
No required environment variables.

### Rendering command

```
pdftoppm -png $INPUT_PDF $OUTPUT_PREFIX
```

### Quality expectations
- Maintain polished visual design: consistent typography, spacing, margins, and section hierarchy.
- Avoid rendering issues: clipped text, overlapping elements, broken tables, black squares, or unreadable glyphs.
- Charts, tables, and images must be sharp, aligned, and clearly labeled.
- Use ASCII hyphens only. Avoid U+2011 (non-breaking hyphen) and other Unicode dashes.
- Citations and references must be human-readable; never leave tool tokens or placeholder strings.

### Final checks
- Do not deliver until the latest PNG inspection shows zero visual or formatting defects.
- Confirm headers/footers, page numbering, and section transitions look polished.
- Keep intermediate files organized or remove them after final approval.

Used this skill to set up a PDF workflow in VS Code, install missing dependencies, render pages from a paper PDF with pdftoppm, and extract text with pypdf. Instructions were clear and practical.
