## Origin

- **Emacs skills** (d2, describe, dired, emacsclient, file-links, gnuplot, highlight, mermaid, open, plantuml, select) — forked from [xenodium/emacs-skills](https://github.com/xenodium/emacs-skills) by Alvaro Ramirez
- **extract-pdf-pages** — original, requires `pdftk` (`apt install pdftk`)

## Requirements

- GNU Emacs with running server daemon (`emacsclient` accessible)
- `pdftk` for PDF extraction skill
- Claude Code with plugins enabled
