if [ -e ~/.agents/skills/'data-migration-expert' ] || [ -L ~/.agents/skills/'data-migration-expert' ]; then echo 'A skill folder named data-migration-expert already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/ratacat/claude-skills' "$d" && git -C "$d" checkout --quiet 'd4b471d05ddad5c69a8c0e1da69fd94e957f0a4b' -- 'skills/data-migration-expert' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/data-migration-expert' ~/.agents/skills/'data-migration-expert' && 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/'data-migration-expert' ~/.claude/skills/'data-migration-expert' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
