# PDF Skill

## 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
