Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'legacy-modernizer' ] || [ -L ~/.agents/skills/'legacy-modernizer' ]; then echo 'A skill folder named legacy-modernizer already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/PIXARTSeu/Synapse' "$d" && git -C "$d" checkout --quiet 'c19c0bc0a04d25a849ce749fe88250e688f06437' -- 'packages/codegraph/data/lifecycle-skills/legacy-modernizer' && mkdir -p ~/.agents/skills && cp -R "$d"/'packages/codegraph/data/lifecycle-skills/legacy-modernizer' ~/.agents/skills/'legacy-modernizer' && 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/'legacy-modernizer' ~/.claude/skills/'legacy-modernizer' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
