Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Convert EPUB card books into Obsidian-ready HyperCard Markdown folders and portable zip files. Use when Codex needs to turn an EPUB with XHTML chapters, table-of-contents cards, keyword index cards, backlinks, Luhmann/Zettelkasten numbers, or cross-links into one Markdown file per card with verified relative links, keyword cards, previous/home/next navigation, and GitHub/shareable zip output.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'epub-hypercard-obsidian' ] || [ -L ~/.agents/skills/'epub-hypercard-obsidian' ]; then echo 'A skill folder named epub-hypercard-obsidian already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/twhsi/skills' "$d" && git -C "$d" checkout --quiet '287d0f4eb1a7df185a9b5108159252f7afc1cdfe' -- 'skills/epub-hypercard-obsidian' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/epub-hypercard-obsidian' ~/.agents/skills/'epub-hypercard-obsidian' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'epub-hypercard-obsidian' ~/.claude/skills/'epub-hypercard-obsidian' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
