The user has a Cardputer-Adv from claude.com/cwc-makers plugged in over USB-C.

Get https://github.com/moremas/build-with-claude into a build-with-claude/ directory under cwd:
- If git is available: git clone (or git pull if it already exists).
- If git is not available: don't install it. Download the GitHub tarball instead — curl and tar ship with macOS, Linux, and Windows 10+ out of the box:
  - macOS / Linux: curl -L https://github.com/moremas/build-with-claude/archive/refs/heads/main.tar.gz | tar xz && mv build-with-claude-main build-with-claude
  - Windows (PowerShell): curl.exe -L -o bwc.zip https://github.com/moremas/build-with-claude/archive/refs/heads/main.zip; tar -xf bwc.zip; Rename-Item build-with-claude-main build-with-claude
- Re-running /maker-setup later just re-downloads (~500KB) — no update mechanism needed.
Invoke the m5-onboard skill and follow it to run onboard/scripts/onboard.py --apps buddy from inside build-with-claude/, surfacing the download-mode button prompt to the user.
When done, tell the user how to launch Antigravity Buddy and ask what they want to build next (see the cardputer-buddy skill for iterating).
