rebyteai 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:
- 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 - Custom path — if no template fits, write a custom HTML in the Kami design system using
references/design.mdtokens andreferences/cheatsheet.mdrules, then render via the same pipeline
Both paths render through scripts/build.py → WeasyPrint. The visual language is consistent across templated and custom documents.

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.
