-Max Mode (parallel best-of-N reasoning with judge selection) can be enabled via `experimental.maxMode` in the config.
+#### Max Mode
+
+Enable by adding `experimental.maxMode` to your config:
+
+```jsonc
+{
+  "experimental": {
+    "maxMode": {}            // default: 5 parallel candidates per step
+    // "maxMode": { "candidates": 3 }  // custom candidate count
+  }
+}
+```
+
+A new **max** agent appears — press `Tab` to switch to it. Same permissions as **build**. Each step costs roughly `candidates ×` normal tokens.

-Max Mode（并行 best-of-N 推理 + 裁判选优）可通过配置中的 `experimental.maxMode` 开启。
+#### Max Mode
+
+在配置中添加 `experimental.maxMode` 开启：
+
+```jsonc
+{
+  "experimental": {
+    "maxMode": {}            // 默认：每步 5 个并行候选
+    // "maxMode": { "candidates": 3 }  // 自定义候选数量
+  }
+}
+```
+
+开启后智能体列表出现 **max**，按 `Tab` 切换。权限与 **build** 相同，每步消耗约为 `candidates ×` 倍。
