-# TJWaterAgentExperimental
+# TJWater Agent 实验服务
 
-Experimental opencode-based Agent service for TJWater UI orchestration.
+基于 OpenCode 的实验性 Agent 服务，用于编排 TJWater 前端交互。
 
-This repository is intentionally separate from the production `TJWaterAgent`
-history. It does not include user authentication or the old `tjwater-cli`
-bridge. Runtime requests use a local default context and can later be wired to a
-real auth provider through `src/context/`.
+本仓库与生产环境中的 `TJWaterAgent` 历史代码相互独立，不包含用户认证，也不包含旧版 `tjwater-cli` 桥接层。运行时请求默认使用本地上下文，后续可通过 `src/context/` 接入实际的认证提供方。
 
-## Current Boundaries
+## 当前边界
 
-- No Keycloak / metadata auth context.
-- No required `Authorization` or `X-Project-Id` headers.
-- No `cli/`, no `tjwater_cli` opencode tool, no free-form CLI command bridge.
-- Agent visual output is expressed through `agent-ui@1` UIEnvelope events.
-- Tools that depend on the TJWater Server are disabled. Arbitrary URLs, SQL,
-  shell commands, and filesystem paths remain unavailable.
+- 不包含 Keycloak 或元数据认证上下文。
+- 不强制要求 `Authorization` 或 `X-Project-Id` 请求头。
+- 不包含 `cli/`、`tjwater_cli` OpenCode 工具或自由形式的 CLI 命令桥接。
+- Agent 的结构化界面输出使用 `agent-ui@1` UIEnvelope 事件；受控浏览器操作使用 `frontend-action@1` 前端动作。
+- 依赖 TJWater Server 的工具处于禁用状态，Agent 不能访问任意 URL、SQL、Shell 命令或文件系统路径。
