 **Common Options**
 
 - `--print/-p` print mode (pipe-friendly)
-- `--output-format` output: text/json/stream-json
+- `--headless` full agent mode without Ink UI, prints streamed events to the terminal
+- `--output-format` output: text/json/stream-json/jsonl
 - `--permission-mode` permission mode
 - `--resume/-r` resume session / `--session-id` set session
 
+**Headless Mode**
+
+- `blade --headless "..."` runs the full agent loop without the interactive Ink UI
+- default permission mode is `yolo`, unless explicitly overridden with `--permission-mode`
+- `--output-format jsonl` emits a stable machine-friendly event stream for CI, sandbox runs, and tests

 **常用选项**
 
 - `--print/-p` 打印模式（适合管道）
-- `--output-format` 输出格式（text/json/stream-json）
+- `--headless` 无 Ink UI 的完整 agent 模式，按终端事件流输出
+- `--output-format` 输出格式（text/json/stream-json/jsonl）
 - `--permission-mode` 权限模式
 - `--resume/-r` 恢复会话 / `--session-id` 指定会话
 
+**Headless 模式**
+
+- `blade --headless "..."` 会运行完整 agent loop，但不启动交互式 Ink UI
+- 默认权限模式为 `yolo`，除非显式传入 `--permission-mode`
+- `--output-format jsonl` 会输出稳定的机器可消费事件流，适合 CI、sandbox 和测试场景
