# PDF

> Use this skill for anything PDF — creating professional PDFs (resumes, one-pagers, white papers, letters, portfolios, equity reports, changelogs, custom documents) with the Kami design system; reading or extracting text/tables; merging, splitting, rotating, watermarking, encrypting; filling PDF forms; extracting embedded images; OCR on scanned PDFs. Trigger on any `.pdf` request or phrases like "make me a PDF", "generate a report", "build me a resume", "one-pager", "white paper", "export to PDF", "professional document".

# PDF Skill

One skill for every PDF task. Read only the sub-reference that matches what the user wants.

## Task → Reference Router

| The user wants to… | Read |
|---|---|
| Create a PDF — resume, one-pager, long doc, letter, portfolio, equity report, changelog, or anything custom | `references/create.md` |
| Understand the visual design system (tokens, typography, colors, layouts) | `references/design.md` |
| Understand how WeasyPrint builds PDFs + troubleshoot render issues | `references/production.md` |
| Write good copy inside a document (tone, rhythm, bilingual conventions) | `references/writing.md` |
| Embed a diagram (architecture, flowchart, quadrant, timeline, chart…) inside a document | `references/diagrams.md` |
| Memorize the non-negotiable rules at a glance | `references/cheatsheet.md` |
| Read or extract text, tables, metadata, or coordinates from a PDF | `references/extract.md` |
| Merge, split, rotate, crop, watermark, or encrypt existing PDFs | `references/manipulate.md` |
| OCR a scanned PDF or extract embedded images | `references/ocr.md` |
| Fill a PDF form (fillable fields or non-fillable flat forms) | `references/forms.md` |
| Do any of the above in JavaScript (pdf-lib, pdfjs-dist) | `references/javascript.md` |

## Default for Creation

When the user asks for any new PDF document, default to **`references/create.md`**. It walks through:
1. **Template path** — match the user's ask to one of the pre-built templates in `assets/templates/` (resume, one-pager, long-doc, letter, portfolio, equity-report, changelog) and fill it with their data
2. **Custom path** — if no template fits, write a custom HTML in the Kami design system using `references/design.md` tokens and `references/cheatsheet.md` rules, then render via the same pipeline

Both paths render through `scripts/build.py` → WeasyPrint. The visual language is consistent across templated and custom documents.

## Core Dependencies

```bash
# Creating PDFs (required)
pip install weasyprint pypdf --break-system-packages
# Linux first-time:
apt install -y libpango-1.0-0 libpangoft2-1.0-0 fonts-noto-cjk

# Reading/manipulating PDFs
pip install pdfplumber pypdfium2 --break-system-packages

# OCR
pip install pytesseract pdf2image --break-system-packages
# Also: apt-get install tesseract-ocr poppler-utils
```

## Routing Tips

- User says "generate report / export PDF / resume / white paper / one-pager / proposal / make me a PDF / professional report" → `create.md`
- User says "extract / read / pull out text / read table" → `extract.md`
- User says "merge / split / rotate / watermark / combine" → `manipulate.md`
- User says "scan / OCR / make searchable" → `ocr.md`
- User says "fill form / form field" → `forms.md`

When unsure, skim this file's router; don't load all references at once.
