# 直接通过 Chrome Web Store ID 安装（需要 chrome-cli 或手动访问）

# macOS 打开扩展页面
open "https://chrome.google.com/webstore/detail/adguard-adblocker/bgnkhhnnamicmpeenaelnjfhikgbkllg"

# 或用命令行检查当前拦截规则数量（AdGuard 安装后）
# 在扩展 Service Worker Console 中执行：
chrome.declarativeNetRequest.getAvailableStaticRuleCount((count) => {
