Origin & Attribution

• Emacs skills (d2, describe, dired, emacsclient, file-links, gnuplot, highlight, mermaid, open, plantuml, select) — forked from 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 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
