- 重建 yolo-classifier-prompts/ 三个缺失的 prompt 文件
- dev.ts/build.ts 扫描 FEATURE_* 环境变量注入 Bun --feature
- AUTO_MODE_ENABLED_DEFAULT 由 feature flag 决定，开 feature 即开 auto mode
- 补充 docs/safety/auto-mode.mdx prompt 模板章节

 # DEV-LOG
 
+## Auto Mode 补全 (2026-04-02)
+
+反编译丢失了 auto mode 分类器的三个 prompt 模板文件，代码逻辑完整但无法运行。
+
+**新增：**
+- `yolo-classifier-prompts/auto_mode_system_prompt.txt` — 主系统提示词
+- `yolo-classifier-prompts/permissions_external.txt` — 外部权限模板（用户规则替换默认值）
+- `yolo-classifier-prompts/permissions_anthropic.txt` — 内部权限模板（用户规则追加）
+
+**改动：**
+- `scripts/dev.ts` + `build.ts` — 扫描 `FEATURE_*` 环境变量注入 Bun `--feature`
+- `cli.tsx` — 启动时打印已启用的 feature
+- `permissionSetup.ts` — `AUTO_MODE_ENABLED_DEFAULT` 由 `feature('TRANSCRIPT_CLASSIFIER')` 决定，开 feature 即开 auto mode
+- `docs/safety/auto-mode.mdx` — 补充 prompt 模板章节
+
+**用法：** `FEATURE_TRANSCRIPT_CLASSIFIER=1 bun run dev`
+
+**注意：** prompt 模板为重建产物。

 ## USER_TYPE=ant TUI 修复 (2026-04-02)
 
 `global.d.ts` 声明的全局函数在反编译版本运行时未定义，导致 `USER_TYPE=ant` 时 TUI 崩溃。
