What this skill can do

if [ -e ~/.agents/skills/'ui-expert' ] || [ -L ~/.agents/skills/'ui-expert' ]; then echo 'A skill folder named ui-expert already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/jacazul-ai/launcher' "$d" && git -C "$d" checkout --quiet 'b4f5a3f40fe54ea5ee255b906100daf027e33bb8' -- 'skills/ui-expert' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/ui-expert' ~/.agents/skills/'ui-expert' && rm -rf "$d"; fi

Or install through the finder skill, which does both.
