## Origin & Attribution

- **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
- **Development workflow skills** (tdd, triage-issue, git-guardrails, improve-codebase-architecture, request-refactor-plan, grill-me, edit-article, write-a-skill) — adapted from [mattpocock/skills](https://github.com/mattpocock/skills) by Matt Pocock
- **emacs-svg-maps**, **extract-pdf-pages** — original by Fénix

### Adaptations from mattpocock originals

- **git-guardrails**: Rewritten to document both `settings.json` deny/ask rules (Fénix's approach) and PreToolUse hook scripts
- **triage-issue**: Added Gitea (`tea`) and BUGS.org support alongside GitHub (`gh`)
- **improve-codebase-architecture**: Added Gitea and Org-file output options
- **request-refactor-plan**: Added Gitea and Org-file output options

## Requirements

- GNU Emacs with running server daemon (`emacsclient` accessible)
- `pdftk` for PDF extraction skill
- `gh` CLI for GitHub issue creation (optional — Gitea/Org alternatives available)
- Claude Code with plugins enabled
