if [ -e ~/.agents/skills/'fastify-best-practices' ] || [ -L ~/.agents/skills/'fastify-best-practices' ]; then echo 'A skill folder named fastify-best-practices already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/mcollina/skills' "$d" && git -C "$d" checkout --quiet 'c75d70dbfbe991d8cec42aeda0b64ff14fbb9ac7' -- 'skills/fastify' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/fastify' ~/.agents/skills/'fastify-best-practices' && 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/'fastify-best-practices' ~/.claude/skills/'fastify-best-practices' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
