+# =============================================================================
+# 删除 GitHub Deployments 工具
+# =============================================================================
+# 用途：清理 GitHub 仓库中失败的或不活跃的 Deployments
+# 依赖：需要安装 gh CLI 并已登录 (gh auth login)
+#
+# 用法：
+#   ./cleanup-github-deployments.sh <owner> <repo> [--dry-run] [--all]
+#
+# 参数：
+#   --dry-run   仅查看，不实际删除
+#   --all       删除所有 Deployment（包括成功的），默认只删除非 success 的
+#
+# 示例：
+#   # 预览将要删除的部署（不实际删除）
+#   ./cleanup-github-deployments.sh i-stack ai-coding-kit --dry-run
+#
+#   # 删除所有失败的/非活跃的部署
+#   ./cleanup-github-deployments.sh i-stack ai-coding-kit
+#
+#   # 删除所有部署（包括成功的）
+#   ./cleanup-github-deployments.sh i-stack ai-coding-kit --all
