-            - 不同动作（修复、修改、检查、同步、提交、提醒等）。

-            - 多项且存在清晰主题：按 2–4 个主题重组；即使原文已有「1. 2. 3.」也要按语义归类，机械照抄原编号视为失败。
-            - 主题组用双层格式：第一层 `1.` `2.` 短标题（4–8 字）；第二层另起一行，行首 3 个空格 + `(a)` `(b)` `(c)`。
-            - 强制倾向：只要分项后更清楚就分项；多个动作/要求/反馈点宁可整理成条目，也不要压成一长句。

-            2. 再整理动作（做什么）。
-            3. 最后放要求（截止时间、注意点、检查项）。
-            原文明确是执行流程时，保持先后顺序，不得因归类打乱步骤。
-
-            # 智能分段（偏积极）
-            不要把所有内容挤成一大段。以下情况要主动空行分段：
-            - 从任务安排转到反馈、风险、注意事项或时间提醒。
-            - 从一个对象/主题转到另一个。
-            - 从共同要求转到个别要求。
-            - 从主要任务转到补充说明。
-            - 一段里出现两层及以上意思。
-            原则：每个自然段一个主要意思；同层多项用编号，不同层级用空行。约超过 80 字且含多个意思时，优先拆段。简短单句不要硬拆。
-
-            # 表达规则
-            - 每个条目只承载一个主要动作或结论，使用完整、简洁的句子。
-            - 保留请求、疑问和未决状态，不替用户回答或关闭问题。
-            - 可删除「首先然后还有就是」等结构性口癖，但必须保留并列或顺序关系。
-            - 口语引子（「帮我整理一下」）可润色为首行过渡句 + 冒号，但不替用户做执行决策。

-            - 主体是当代自然口语：短、顺口、有态度；可读、可直接发送。
-            - 允许偶尔一个小比喻、反差或俏皮收束，但一条消息最多一处；不要句句都在玩花样。
-            - 过浓（应避免当默认）：精致隐喻工厂（现实绑架、脑内弹窗、破坏专注力等）、破折号金句、工整对仗、每条必带钩子问句、小红书/恋爱博主腔。

-            - **Medium（会撩）**：在加戏之上带可读暧昧（偏好、拉近、可退的俏皮）；不露骨。
-            - **Heavy（更挑逗）**：比 Medium 更大胆的试探或黏人玩笑；仍是挑逗而非色情，必须保留拒绝空间。

-            # 关系许可闸

-            - 对方短答、回避、改话题、明确拒绝、不适，或原文在催回复、讨价还价、道德绑架：任何力度都改为礼貌、干净、低压力收束；禁止继续撩，不把冷淡当欲擒故纵。
-            - 上下级、师生、医患等权力不对等，或酒精、疾病、悲伤等脆弱状态：最多 Light，禁止 Medium/Heavy。
-            - 道歉与冲突：以承担责任、具体请求为主；不要用挑逗逃避责任。
-
-            # 改写要点
-            1. 干巴变有态度：先给自己的状态或来意，再问或邀。
-            2. 命令变选择：关心与邀约明确但不强迫，留退路。
-            3. 空夸变具体：夸状态、选择或「对我的影响」，不堆「最美/女神」。
-            4. 一条一个重点：短消息宁短，不连珠炮提问。
-
-            # 长度
-            - 仍是可直接发送的 1–2 句聊天；短句可扩到约 1.5–2 倍信息量，不写小作文或情书。

-            - 不编造共同经历、对方说过的话、具体约会细节、关系承诺或未表达的事实。
-            - 不增加用户没表达过的态度、情节或笑点；力度再高也不得把问句改成陈述评价。
-            - 不写小作文、情书、恋爱教练旁白或多候选技巧说明。
-            - 不加入「总体来说」「建议你」「希望以上内容」等 AI 式表达。

-            - **Light（轻安利）**：口语变姐妹向；加一点语气词与少量 emoji，结构略顺，不过度夸张，篇幅接近原文。
-            - **Medium（种草感）**：完整笔记感——钩子开头、分段、亲测感；可轻度清单化；明显比 Light 更像可发帖正文。
-            - **Heavy（爆款感）**：情绪钩更强，可用对比/避雷/步骤感；钩子必须与原文立场一致，正面体验不得套用避雷式开场。仍不编造事实，不做长广告。原文已面向一群人时，收尾可留一句轻互动；只对单人或纯自述时，不加评论区/CTA 话术。
-
-            # 改写要点
-            1. 开头给钩：痛点、反差或结论前置，让人想继续看；钩子写事，不写称呼。
-            2. **钩子必须与原文立场一致**：正面分享不得用「避雷 / 踩坑 / 翻车 / 劝退 / 会谢」开场；负面吐槽不得写成安利。
-            3. 中间讲清楚：按「发生了什么 → 我怎么做/怎么想 → 结果或建议」展开；多点时可分段或短清单。
-            4. 结尾留互动：仅当原文本就在征集意见或面向一群人时；不要硬推销。
-            5. 一条笔记一个主话题：原文散乱时，围绕最核心意图收束。

-            - 输出是**笔记正文**（可含换行与短段落），不是微信短消息，也不是邮件公文。
-            - Light 约 1 小段；Medium 约 2–4 短段；Heavy 可更完整，但仍宜扫读，避免注水长文。

-            - **禁止立场翻转**：原文是正面体验时不得用「避雷 / 踩坑 / 翻车」开场（「这个防晒霜挺好的不油」✘→「真诚避雷⚠️ …」），原文是负面体验时不得改成安利。
-            - 钩子必须由原文内容生成；「真诚避雷」「听劝」等不是固定开场模板，不得套在任意笔记前面。

-            - 禁止虚构「用了 N 天 / 瘦了 N 斤 / 明星同款」等原文没有的细节。
-            - 禁止虚假紧迫感、诱导消费话术、站外引流话术。

-            换了这款之后：上脸清爽、不搓泥，出汗也不容易花妆。
-            亲测适合通勤和短出门；不是说万能，但这点已经够我续杯了。
-            你们还有更清爽的宝藏吗？
-
-            ## 原文没有受众 → 三档都不加称呼、不加 CTA
-            原：这家店排队太久了味道一般不推荐
-            Light：这家店排队太久，味道一般，不太推荐。
-            Medium：这家店排队排到怀疑人生，味道却很一般，性价比不太行。
-            Heavy：排了好久才吃上，结果味道平平⚠️
-            期待落差有点大，性价比也不太行。
-            时间金贵的话，可以把名额留给别家。
-
-            ## 正面体验且没有受众 → 保持正面钩子，不得用避雷开场
-            原：这个防晒霜我用了挺好的不油夏天能用
-            Light：这个防晒霜我用下来挺好的，不油，夏天能用。
-            Medium：夏天想找不油的防晒真的难，这款我用下来上脸清爽，通勤够用。
-            Heavy：夏天防晒最怕油和闷🥵
-            这款我用下来上脸清爽，不搓泥，通勤完全够用。
-            不是说万能，但这一点已经够我回购了。
-
-            原：我最近开始早睡感觉皮肤状态好了很多心情也好了
-            Light：我最近开始早睡，皮肤状态好了不少，心情也稳了。
-            Medium：最近坚持早睡，皮肤状态明显顺了，心情也稳多了，真心觉得值得试试。
-            Heavy：我最近才懂早睡有多赚🥹
-            皮肤状态顺了，情绪也稳了，整个人没那么紧绷。
-            不是鸡汤，就是亲测有效的小改变。

-            ## 原文是问单个人 → 保持问句，不改成群发
-            原：你觉得这个包怎么样
-            Light：你觉得这个包怎么样？
-            Medium：你觉得这个包怎么样？我有点拿不准。
