Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'crystaljson' ] || [ -L ~/.agents/skills/'crystaljson' ]; then echo 'A skill folder named crystaljson already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/SnowBankSDK/foundationdb-dotnet-client' "$d" && git -C "$d" checkout --quiet 'e8d2b6024a04246106b548c55f3d27dbd4de73ea' -- '.claude/skills/crystaljson' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/crystaljson' ~/.agents/skills/'crystaljson' && 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/'crystaljson' ~/.claude/skills/'crystaljson' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
