|
||||
|
||||
REPL 内所有 slash command 由程序直接处理，不进入 agent loop。
|
||||
|
||||
REPL 会显示当前模式提示符，例如 `build >` 或 `plan >`。
|
||||
|
||||
当前项目支持最小 memory：使用 `/remember` 保存长期信息，使用 `/memory` 查看。
|
||||
|
||||
写操作和 Bash 默认需要确认，可通过 `--auto-approve` 或 `/permissions auto-on` 跳过。
|
||||
|
||||
工作区外访问和 `plan` 模式限制属于硬性边界，不通过审批放行。
|
||||
|
||||
支持 `/mode build` 和 `/mode plan` 两种模式，`plan` 为只读规划模式。
|
||||
|
||||
`/clear` 是清空当前上下文的主别名，等价于 `/new`。
|
||||
|
||||
未明确说明时，使用以下默认值：
|
||||
|
||||
- 工作目录：当前进程目录

- 修改已有文件时，优先使用 `Edit`，而不是 `Bash` 或 `Write`
|

- 需要创建或覆盖文件时，优先使用 `Write` 工具，而不是 `Bash`
|
||||
- 会话与 memory 管理优先使用 slash command，而不是自然语言或 `Bash` 探查对应文件
|
||||
- 优先通过 `/help` 查看当前命令，而不是猜测命令格式
|
||||
- 长期有价值的项目约束或偏好，优先使用 `/remember` 保存
|

- 高风险操作会触发确认，优先先读再改，减少无意义审批
|
||||
- 复杂任务可先切换到 `/mode plan` 进行规划，再切换回 `/mode build` 执行
