We could use $(which npx) to make this more reliable across repos

echo '#!/bin/sh' > /usr/local/bin/npx && \
echo 'echo "npx is disabled for security reasons. Use explicit package installation instead." >&2' >> /usr/local/bin/npx && \
echo 'exit 1' >> /usr/local/bin/npx && \
chmod +x /usr/local/bin/npx

FYI This just avoids npx for now, version pinning following in a follow-up PR
