What this skill can do

if [ -e ~/.agents/skills/'competition-zip-archive' ] || [ -L ~/.agents/skills/'competition-zip-archive' ]; then echo 'A skill folder named competition-zip-archive already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/zhaoxuya520/reverse-skill' "$d" && git -C "$d" checkout --quiet 'cab634bd855fc287f6e420c1f36fd1a6b9245960' -- 'CTF-Sandbox-Orchestrator/competition-zip-archive' && mkdir -p ~/.agents/skills && cp -R "$d"/'CTF-Sandbox-Orchestrator/competition-zip-archive' ~/.agents/skills/'competition-zip-archive' && rm -rf "$d"; fi
