+Hold Key / Auto-Repeat
+======================
+
+``type_keyboard`` is an instant down+up and ``input_macro.run_sequence`` can
+hand-roll a press / wait / release, but there was no primitive for "hold this key
+for N seconds" (game movement, hold-to-scroll) or "send it at R presses per
+second" (auto-repeat).
+
+:func:`plan_key_hold` builds the deterministic op-plan (pure, unit-testable);
+:func:`hold_key` dispatches it through an injectable ``sink`` and ``sleep`` so it
+is tested without real input or real waiting. Imports no ``PySide6``.
+
+Headless API
+------------
+
+.. code-block:: python
+
+    from je_auto_control import hold_key, plan_key_hold
+
+    hold_key("key_d", duration_s=1.5)              # press, hold 1.5s, release
+    hold_key("key_down", duration_s=2.0, rate_hz=20)   # 40 key events @ 50ms
+
+    plan_key_hold("space", 1.0)
+    # [{'op': 'press', 'key': 'space'},
+    #  {'op': 'wait', 'seconds': 1.0},
+    #  {'op': 'release', 'key': 'space'}]
+
+With ``rate_hz`` unset the key is pressed, held for ``duration_s``, then released.
+With ``rate_hz`` set it is sent as ``round(duration_s * rate_hz)`` discrete key
+events spaced ``1 / rate_hz`` apart — simulated auto-repeat for movement / scroll
+loops. A non-positive duration or rate raises ``ValueError``. ``hold_key`` routes
+the ``wait`` steps to ``sleep`` and the key steps to ``sink``, both injectable.
+
+Executor commands
+-----------------
+
+``AC_hold_key`` takes ``key`` plus ``duration_s`` and an optional ``rate_hz`` and
+returns ``{ops, plan}``. It is exposed as the MCP tool ``ac_hold_key`` and as a
+Script Builder command under **Keyboard**.

+按住按鍵 / 自動重複
+==================
+
+``type_keyboard`` 是瞬間的按下+放開,``input_macro.run_sequence`` 雖可手動拼出按下 / 等待 / 放開,但先前沒有
+「按住此鍵 N 秒」(遊戲移動、按住捲動)或「每秒送 R 次」(自動重複)的基本元件。
+
+:func:`plan_key_hold` 建立決定性的操作計畫(純函式、可單元測試);:func:`hold_key` 透過可注入的 ``sink``
+與 ``sleep`` 派發,因此可在無真實輸入、無真實等待下測試。不匯入 ``PySide6``。
+
+無頭 API
+--------
+
+.. code-block:: python
+
+    from je_auto_control import hold_key, plan_key_hold
+
+    hold_key("key_d", duration_s=1.5)              # 按下、按住 1.5 秒、放開
+    hold_key("key_down", duration_s=2.0, rate_hz=20)   # 40 個按鍵事件 @ 50ms
+
+    plan_key_hold("space", 1.0)
+    # [{'op': 'press', 'key': 'space'},
+    #  {'op': 'wait', 'seconds': 1.0},
+    #  {'op': 'release', 'key': 'space'}]
+
+未設定 ``rate_hz`` 時,鍵會被按下、按住 ``duration_s``、再放開。設定 ``rate_hz`` 時,會送出
+``round(duration_s * rate_hz)`` 個相隔 ``1 / rate_hz`` 的離散按鍵事件——用於移動 / 捲動迴圈的模擬自動重複。
+非正數的時長或頻率會拋出 ``ValueError``。``hold_key`` 將 ``wait`` 步驟導向 ``sleep``、按鍵步驟導向 ``sink``,
+兩者皆可注入。
+
+執行器命令
+----------
+
+``AC_hold_key`` 接受 ``key`` 以及 ``duration_s`` 與選用的 ``rate_hz``,並回傳 ``{ops, plan}``。它以 MCP 工具
+``ac_hold_key`` 以及 Script Builder 中 **Keyboard** 分類下的命令提供。
