1. 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:
- 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.
2. 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.
