# 把 new-project skill 安装到 ~/.claude/skills/（全局，任意项目可用）。

# 单一源原则：verify.sh 只在仓库根 scripts/ 维护一份，
# 本脚本在安装时把它和 SKILL.md 组装进 ~/.claude/skills/new-project/，
# 使安装后的 skill 自包含（无需仓库即可运行验证）。
#
# 用法：
#   curl -fsSL https://raw.githubusercontent.com/baozaotumao2025/scaffold/main/scripts/install-skill.sh | bash
# 或在已克隆的仓库内：
#   ./scripts/install-skill.sh
