+description: 调用小说家 agent 进行小说风格续写。自动复制小说原文到 novelist 工作区。
+---
+
+# Novelist Bridge
+
+通过 Gateway API 同步调用 `novelist` agent 进行小说创作。
+**自动将小说原文复制到 novelist 工作区**，让 novelist 能在本地直接读取原文正文，而不是仅靠标题推断。
+
+## 脚本位置
+
+`scripts/ask_novelist.py`
+
+## 用法
+
+```bash
+# 基本用法（自动查找默认小说文件）
+python scripts/ask_novelist.py "续写请求内容"
+
+# 指定小说文件路径
+python scripts/ask_novelist.py --novel /path/to/novel.txt "续写请求内容"
+
+# 从 stdin 读取
+echo "续写内容" | python scripts/ask_novelist.py
+```
+
+## 配置
+
+修改 `ask_novelist.py` 顶部的常量：
+
+| 变量 | 说明 |
+|------|------|
+| `GATEWAY_URL` | Gateway API 地址 |
+| `GATEWAY_TOKEN` | Gateway API Token |
+| `NOVELIST_MODEL` | novelist agent model ID |
+| `NOVELIST_WORKSPACE` | novelist 工作区路径 |
+| `NOVEL_TARGET_NAME` | 复制到工作区后的文件名 |
+
+## 调用链路
+
+```
+caller agent → ask_novelist.py → 复制小说到 novelist 工作区 → Gateway API → novelist agent → 回复
+```
+
+## 注意事项
+
+- 超时默认 180 秒
+- 如果 novelist 正在忙，会排队等待
+- 脚本自动跳过已存在的相同文件（按文件大小比对），减少磁盘写操作
