 - 升级到 v0.18.1：十三个 Skill 统一在关键步骤开始前，用带图标和边框的醒目文本块说明「第几步、当前步骤、做什么、为什么」；直接调用也生效，同一步不重复刷屏。更新后新建任务或会话加载新指令。
+- 升级到 v0.18.2：步骤提示改为带左侧竖线的三行引用块，保留图标和连续编号；使用普通正文字号与字重，移除等号边框、大标题和整段粗体。宿主不支持引用时回退普通三行文字。更新后新建任务或重新加载技能。
 - 若从 v0.6.x 升级，另确认旧 `scd-dev-loop` 已消失。

 ## 展示方式

-```text
-======= 🧪 第 3 步：验证修改 =======
-🎯 做什么：运行本次变更的相关测试和仓库检查。
-💡 为什么：确认修改解决了目标问题，并检查是否影响现有行为。

+> 🎯 做什么：运行本次变更的相关测试和仓库检查。\
+> 💡 为什么：确认修改解决了目标问题，并检查是否影响现有行为。
 ```
 
+实际发送时直接输出引用块，不要套代码围栏。三项各占一行；前两行末尾用反斜杠保留换行。不使用等号边框、Markdown 标题或整段粗体；标题和字段也保持普通字重。行动和原因各用简短的一句话，避免长段落。
+
 步骤标题必须带与当前行动相符的图标，例如 🔎 检查、🛠️ 实施、🧪 验证、👥 独立验收、⏳ 等待或 🚧 阻塞；「做什么」与「为什么」分别用 🎯 和 💡 标识。图标不能代替文字。用具体中文任务名，必要时附技能名；不要只写「执行 scd-quickdev」或「处理中」。行动和原因各用一句话，原因应结合当前任务说明目的、要消除的不确定性或要避免的风险，不用「因为流程要求」代替解释。只提供用户可理解的简短理由，不输出内部推理链。
 
-宿主不支持文本块时，使用带图标的粗体步骤标题与独立的「🎯 做什么」「💡 为什么」两行，保持醒目。必须注明当前第几步，默认用「第 N 步：具体任务名」，实际输出时把 N 替换为数字。按当前任务已展示的实际步骤从 1 连续编号，进入新的有意义步骤才递增；同一步进度更新沿用原编号，切换子技能不重置。恢复任务时先核对已有编号，无法核实时明确以本次恢复为编号起点。总步数已确定时显示「第 N/M 步」；总步数未知时只显示「第 N 步」，不编造总数、百分比或固定流程。
