description: Operate Uni-Lab host node via REST API — create resources, test latency, test resource tree, manual confirm. Use when the user mentions host_node, creating resources, resource management, testing latency, or any host node operation.

# Host Node API Skill
## 设备信息
- **device_id**: `host_node`
- **Python 源码**: `unilabos/ros/nodes/presets/host_node.py`
- **设备类**: `HostNode`
- **动作数**: 4`create_resource`, `test_latency`, `auto-test_resource`, `manual_confirm`
## 前置条件(缺一不可)
使用本 skill 前,**必须**先确认以下信息。如果缺少任何一项,**立即向用户询问并终止**,等补齐后再继续。
### 1. ak / sk → AUTH
从启动参数 `--ak` `--sk` 或 config.py 中获取,生成 token`base64(ak:sk)``Authorization: Lab <token>`
### 2. --addr → BASE URL
| `--addr` 值 | BASE |
| ------------ | ----------------------------------- |
| `test` | `https://leap-lab.test.bohrium.com` |
| `uat` | `https://leap-lab.uat.bohrium.com` |
| `local` | `http://127.0.0.1:48197` |
| 不传(默认) | `https://leap-lab.bohrium.com` |
确认后设置:
```bash
BASE="<根据 addr 确定的 URL>"
AUTH="Authorization: Lab <token>"
```
**两项全部就绪后才可发起 API 请求。**
## Session State
在整个对话过程中agent 需要记住以下状态,避免重复询问用户:
- `lab_uuid` — 实验室 UUID首次通过 API #1 自动获取,**不需要问用户**
- `device_name``host_node`
## 请求约定
所有请求使用 `curl -s`POST/PATCH/DELETE 需加 `Content-Type: application/json`
> **Windows 平台**必须使用 `curl.exe`(而非 PowerShell 的 `curl` 别名)。
---
## API Endpoints
### 1. 获取实验室信息(自动获取 lab_uuid
```bash
curl -s -X GET "$BASE/api/v1/edge/lab/info" -H "$AUTH"
```
返回 `data.uuid``lab_uuid``data.name``lab_name`
### 2. 创建工作流
```bash
curl -s -X POST "$BASE/api/v1/lab/workflow/owner" \
-H "$AUTH" -H "Content-Type: application/json" \
-d '{"name":"<名称>","lab_uuid":"<lab_uuid>","description":"<描述>"}'
```
返回 `data.uuid``workflow_uuid`。创建成功后告知用户链接:`$BASE/laboratory/$lab_uuid/workflow/$workflow_uuid`
### 3. 创建节点
```bash
curl -s -X POST "$BASE/api/v1/edge/workflow/node" \
-H "$AUTH" -H "Content-Type: application/json" \
-d '{"workflow_uuid":"<workflow_uuid>","resource_template_name":"host_node","node_template_name":"<action_name>"}'
```
- `resource_template_name` 固定为 `host_node`
- `node_template_name` — action 名称(如 `create_resource`, `test_latency`
### 4. 删除节点
```bash
curl -s -X DELETE "$BASE/api/v1/lab/workflow/nodes" \
-H "$AUTH" -H "Content-Type: application/json" \
-d '{"node_uuids":["<uuid1>"],"workflow_uuid":"<workflow_uuid>"}'
```
### 5. 更新节点参数
```bash
curl -s -X PATCH "$BASE/api/v1/lab/workflow/node" \
-H "$AUTH" -H "Content-Type: application/json" \
-d '{"workflow_uuid":"<wf_uuid>","uuid":"<node_uuid>","param":{...}}'
```
`param` 直接使用创建节点返回的 `data.param` 结构,修改需要填入的字段值。参考 [action-index.md](action-index.md) 确定哪些字段是 Slot。
### 6. 查询节点 handles
```bash
curl -s -X POST "$BASE/api/v1/lab/workflow/node-handles" \
-H "$AUTH" -H "Content-Type: application/json" \
-d '{"node_uuids":["<node_uuid_1>","<node_uuid_2>"]}'
```
### 7. 批量创建边
```bash
curl -s -X POST "$BASE/api/v1/lab/workflow/edges" \
-H "$AUTH" -H "Content-Type: application/json" \
-d '{"edges":[{"source_node_uuid":"<uuid>","target_node_uuid":"<uuid>","source_handle_uuid":"<uuid>","target_handle_uuid":"<uuid>"}]}'
```
### 8. 启动工作流
```bash
curl -s -X POST "$BASE/api/v1/lab/workflow/<workflow_uuid>/run" -H "$AUTH"
```
### 9. 运行设备单动作
```bash
curl -s -X POST "$BASE/api/v1/lab/mcp/run/action" \
-H "$AUTH" -H "Content-Type: application/json" \
-d '{"lab_uuid":"<lab_uuid>","device_id":"host_node","action":"<action_name>","action_type":"<type>","param":{...}}'
```
`param` 直接放 goal 里的属性,**不要**再包一层 `{"goal": {...}}`
> **WARNING: `action_type` 必须正确,传错会导致任务永远卡住无法完成。** 从下表或 `actions/<name>.json` 的 `type` 字段获取。
#### action_type 速查表
| action | action_type |
|--------|-------------|
| `test_latency` | `UniLabJsonCommand` |
| `create_resource` | `ResourceCreateFromOuterEasy` |
| `auto-test_resource` | `UniLabJsonCommand` |
| `manual_confirm` | `UniLabJsonCommand` |
### 10. 查询任务状态
```bash
curl -s -X GET "$BASE/api/v1/lab/mcp/task/<task_uuid>" -H "$AUTH"
```
### 11. 运行工作流单节点
```bash
curl -s -X POST "$BASE/api/v1/lab/mcp/run/workflow/action" \
-H "$AUTH" -H "Content-Type: application/json" \
-d '{"node_uuid":"<node_uuid>"}'
```
### 12. 获取资源树(物料信息)
```bash
curl -s -X GET "$BASE/api/v1/lab/material/download/$lab_uuid" -H "$AUTH"
```
注意 `lab_uuid` 在路径中。返回 `data.nodes[]` 含所有节点(设备 + 物料),每个节点含 `name``uuid``type``parent`
### 13. 获取工作流模板详情
```bash
curl -s -X GET "$BASE/api/v1/lab/workflow/template/detail/$workflow_uuid" -H "$AUTH"
```
> 必须使用 `/lab/workflow/template/detail/{uuid}`,其他路径会返回 404。
### 14. 按名称查询物料模板
```bash
curl -s -X GET "$BASE/api/v1/lab/material/template/by-name?lab_uuid=$lab_uuid&name=<template_name>" -H "$AUTH"
```
返回 `data.uuid``res_template_uuid`,用于 API #15
### 15. 创建物料节点
```bash
curl -s -X POST "$BASE/api/v1/edge/material/node" \
-H "$AUTH" -H "Content-Type: application/json" \
-d '{"res_template_uuid":"<uuid>","name":"<名称>","display_name":"<显示名>","parent_uuid":"<父节点uuid>","data":{...}}'
```
### 16. 更新物料节点
```bash
curl -s -X PUT "$BASE/api/v1/edge/material/node" \
-H "$AUTH" -H "Content-Type: application/json" \
-d '{"uuid":"<节点uuid>","display_name":"<新名称>","data":{...}}'
```

## 渐进加载策略
1. **SKILL.md**(本文件)— API 端点 + session state 管理
2. **[action-index.md](action-index.md)** — 按分类浏览 4 个动作的描述和核心参数
3. **[actions/\<name\>.json](actions/)** — 仅在需要构建具体请求时,加载对应 action 的完整 JSON Schema
