Install

if [ -e ~/.agents/skills/'xlsx' ] || [ -L ~/.agents/skills/'xlsx' ]; then echo 'A skill folder named xlsx already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/idexal/idexal-skills' "$d" && git -C "$d" checkout --quiet '7152f82d6734b10c03b70424e7c15016fecfc0b2' -- 'xlsx' && mkdir -p ~/.agents/skills && cp -R "$d"/'xlsx' ~/.agents/skills/'xlsx' && rm -rf "$d"; fi

For Claude Code: ln -s ~/.agents/skills/'xlsx' ~/.claude/skills/'xlsx' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
