+### Custom CLI Registration
+
+Register **any API as a custom CLI** via Dashboard API Settings:
+
+```json
+// Example: Register "deepseek" as custom CLI
+{
+  "tools": {
+    "deepseek": {
+      "enabled": true,
+      "type": "api-endpoint",
+      "endpoint": "https://api.deepseek.com/v1/chat",
+      "apiKey": "your-api-key"
+    }
+  }
+}
+```
+
+After registration, use it semantically:
+
+```text
+User: "Use DeepSeek to analyze this algorithm complexity"
+→ System auto-calls: deepseek CLI (your custom endpoint)
+
+User: "Let DeepSeek and Gemini compare their analysis results"
+→ System auto-calls: deepseek + gemini in parallel
+```
+
+> ⚙️ **Dashboard**: `ccw view` → Status → API Settings to manage custom CLIs.

+### 自定义 CLI 注册
+
+通过 Dashboard API Settings **注册任意 API 为自定义 CLI**：
+
+```json
+// 示例：注册 "deepseek" 为自定义 CLI
+{
+  "tools": {
+    "deepseek": {
+      "enabled": true,
+      "type": "api-endpoint",

+      "apiKey": "your-api-key"
+    }
+  }
+}
+```
+
+注册后即可语义调用：
+
+```text
+用户: "使用 DeepSeek 分析这个算法复杂度"
+→ 系统自动调用: deepseek CLI（你的自定义端点）
+
+用户: "让 DeepSeek 和 Gemini 对比分析结果"
+→ 系统自动调用: deepseek + gemini 并行执行
+```
+
+> ⚙️ **Dashboard 配置**: `ccw view` → Status → API Settings 管理自定义 CLI。
