Usage

/preset command

Type it in the composer input. With no argument (/preset, /preset list, /preset ls, /preset ?) it prints the current mode and the full roster:

当前模式：standard（标准模式）
可用模式：
  minimal（极简模式）
  standard（标准模式） ← 当前
  code（代码模式）
  cordis（创造模式）
  my-custom（我的自定义模式）

用法：/preset  —— 强制切换当前会话的模式（不要求会话为空，工具集立即更换）

The host emits these strings in Chinese: first line = current mode (（未加入 preset） when none), rows = （display name）, ← 当前 marks the active one, [损坏: ...] a broken preset; last line = usage hint.

With an argument:

> /preset code          # switch
已强制切换当前会话模式：standard → code。模型可见的工具与提示词已更换；已产生的历史记录保持原样。
> /preset code          # already on target
当前会话已经是模式 code。
> /preset bogus         # failure
切换失败：

The success line reads: "Force-switched this session's mode: standard → code. The model-visible tools and prompts have been replaced; existing history is left as-is."

set_agent_preset tool

The model calls it on your behalf; visible under every preset (the tool registry resolves agent → preset → global).

Parameter	Type	Required	Description
preset	string	yes	Target preset id (standard / minimal / code / cordis, or a locally authored id); pass "" to list available ids

{ "preset": "code" }   // → { "ok": true, "from": "standard", "to": "code" }
{ "preset": "" }       // → { "ok": true, "unchanged": true, "available": [ { "id": "minimal", "name": "极简模式" }, ... ] }
// subagent call       // → { "ok": false, "error": "set_agent_preset 只能切换顶层会话的模式，子代理不可切换。" }

Result shape: { ok, from?, to?, unchanged?, available?, error? }.

Composer tool-row dropdown

A compact selector in the input tool row (conversation.input.right slot, order 10, label "模式切换"), next to the model picker:

1. Open it — every available mode is listed as name (id).
2. Pick one; the session switches immediately.
3. On failure a browser alert shows the reason and the selection snaps back.

It polls /status every 5 seconds (changes from any entry point are reflected) and is disabled while a switch is in flight, when the session is not live, or when no presets are installed (a single disabled "模式" entry).
