-description: 自动同步和刷新项目文档，确保 Markdown 文件与当前代码功能状态完全一致。

-# Documentation Refresher Skill
-
-此技能用于在项目架构发生重大调整（如功能下线、重心转移）后，自动重写和更新项目的所有 Markdown 文档。
-
-## 核心任务
-
-1. **代码扫描**：分析 `run.py` 和核心逻辑，识别哪些功能是“活跃的”，哪些功能是“暂停/移除的”。
-2. **术语统一**：确保所有文档使用一致的语气（例如从“监控机器人”转向“天气查询机器人”）。
-3. **多语言同步**：确保 `_ZH.md` 与英文版文档内容同步。
-
-## 更新准则
-
-- **状态准确性**：如果功能已在代码中被注释（如监控引擎、模拟交易），文档必须明确标注为“已暂停”或直接移除。
-- **示例更新**：更新文档中的 Telegram 指令示例，移除已下线的指令（如 `/signal`, `/portfolio`）。
-- **流程简化**：针对当前“天气查询模式”，简化安装和运行流程说明。
-
-## 使用流程
-
-1. 查看 `run.py` 确认当前运行模式。
-2. 遍历项目根目录下所有的 `.md` 文件。
-3. 对每个文件内容进行重构，保持格式美观。
-4. 校验多语言版本的一致性。
