+## DSH 设置页（手表/手机设置）
+
+插件注册了 dsh-watch 设置命名空间。装好后，在 DSH 的 设置 -> 插件（或对应插件设置区）里可填：
+
+- mode: direct / relay
+- serverUrl / userId / token
+- apiKey（DeepSeek API Key，用于 harness.balance 直接查余额；留空则用 DEEPSEEK_API_KEY 环境变量/credentials）
+- reconnectMs / timeoutMs
+- host / port（direct 模式）
+
 ## 暴露方法
 
 透传 DSH apiProxy：
 
-- harness.status / harness.prompt / harness.cancel
+- harness.status / harness.prompt / harness.cancel / harness.balance
 - session.list create history prompt cancel rename fork models selectModel attachment
 - goal.* subagent.* workspace.* host.*
 - skill.list agentPreset.* llm.* settings.* credentials.*
