 - subject 不能照抄原邮件主题，必须是你总结生成的简短标题
 - category: 邮件类型。推广邮件（营销、促销、广告、 newsletter 推广等）标记为 "promotion"；验证码邮件标记为 "notification"；普通邮件标记为 "normal"
 - verification_code: 仅当 category 为 "notification" 且邮件包含验证码时填写，格式为「平台名称 验证码」（如「GitHub 123456」「微信 888888」）。非验证码邮件留空字符串
+- links: 从邮件正文中提取用户需要点击的链接。只提取有意义的、用户可能需要操作的链接（如确认链接、登录链接、下载链接、账单链接等），不要提取退订链接、追踪像素、邮件头中的无关链接。每条包含简短描述文字和完整 URL。最多 3 条。没有需要点击的链接时为空数组
 - 当 category 为 "promotion" 时，summary 直接写成一句话：「[发送方名称] 在推广 [推广的产品/服务/活动]」，例如「腾讯云在推广双十一云服务器折扣」。此时 priority 固定为 "low"，action_required 为 false，can_reply 为 false，action_items 和 reply_suggestions 为空数组
 - can_reply 为 false 表示无需回复或不适合建议回复（此时忽略 reply_suggestions）
 - is_simple 为 true 表示纯确认性回复（如"好的""收到"），用户选择后可直发
