What it does
Host Node is an agent skill from deepmodeling/Uni-Lab-OS. Operate Uni-Lab host node via REST API — create resources, test latency, test resource tree, manual confirm. Use when the user mentions hostnode, creating resources, resource management, testing latency, or any host node operation.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files (for example `action-index.md`, `actions/create_resource.json` and `actions/manual_confirm.json`).
It sits in Backend & APIs, covering REST APIs. The repository describes itself as: A Platform for Laboratory Automation. The licence is GPL-3.0.
When your agent uses it
- The user mentions hostnode
- Creating resources
- Resource management
- Testing latency
Example prompts
- “/host-node”
Requirements
- Python 3
Workflow steps
12 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 43923ec. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
curl
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
leap-lab.test.bohrium.comleap-lab.uat.bohrium.comleap-lab.bohrium.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Host Node loads about 1.9k tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 277 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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：
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）
curl -s -X GET "$BASE/api/v1/edge/lab/info" -H "$AUTH"返回 data.uuid 为 lab_uuid，data.name 为 lab_name。
2. 创建工作流
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 为 workflow_uuid。创建成功后告知用户链接：$BASE/laboratory/$lab_uuid/workflow/$workflow_uuid
3. 创建节点
curl -s -X POST "$BASE/api/v1/edge/workflow/node" \
-H "$AUTH" -H "Content-Type: application/json" \
-d '{"workflow_uuid":"<workflow_uuid>","resource_template_name":"host_node","node_template_name":"<action_name>"}'resource_template_name固定为host_nodenode_template_name— action 名称（如create_resource,test_latency）
4. 删除节点
curl -s -X DELETE "$BASE/api/v1/lab/workflow/nodes" \
-H "$AUTH" -H "Content-Type: application/json" \
-d '{"node_uuids":["<uuid1>"],"workflow_uuid":"<workflow_uuid>"}'5. 更新节点参数
curl -s -X PATCH "$BASE/api/v1/lab/workflow/node" \
-H "$AUTH" -H "Content-Type: application/json" \
-d '{"workflow_uuid":"<wf_uuid>","uuid":"<node_uuid>","param":{...}}'param 直接使用创建节点返回的 data.param 结构，修改需要填入的字段值。参考 action-index.md 确定哪些字段是 Slot。
6. 查询节点 handles
curl -s -X POST "$BASE/api/v1/lab/workflow/node-handles" \
-H "$AUTH" -H "Content-Type: application/json" \
-d '{"node_uuids":["<node_uuid_1>","<node_uuid_2>"]}'7. 批量创建边
curl -s -X POST "$BASE/api/v1/lab/workflow/edges" \
-H "$AUTH" -H "Content-Type: application/json" \
-d '{"edges":[{"source_node_uuid":"<uuid>","target_node_uuid":"<uuid>","source_handle_uuid":"<uuid>","target_handle_uuid":"<uuid>"}]}'8. 启动工作流
curl -s -X POST "$BASE/api/v1/lab/workflow/<workflow_uuid>/run" -H "$AUTH"9. 运行设备单动作
curl -s -X POST "$BASE/api/v1/lab/mcp/run/action" \
-H "$AUTH" -H "Content-Type: application/json" \
-d '{"lab_uuid":"<lab_uuid>","device_id":"host_node","action":"<action_name>","action_type":"<type>","param":{...}}'param 直接放 goal 里的属性，不要再包一层 {"goal": {...}}。
WARNING:
action_type必须正确，传错会导致任务永远卡住无法完成。 从下表或actions/<name>.json的type字段获取。
action_type 速查表
| action | action_type |
|---|---|
test_latency | UniLabJsonCommand |
create_resource | ResourceCreateFromOuterEasy |
auto-test_resource | UniLabJsonCommand |
manual_confirm | UniLabJsonCommand |
10. 查询任务状态
curl -s -X GET "$BASE/api/v1/lab/mcp/task/<task_uuid>" -H "$AUTH"11. 运行工作流单节点
curl -s -X POST "$BASE/api/v1/lab/mcp/run/workflow/action" \
-H "$AUTH" -H "Content-Type: application/json" \
-d '{"node_uuid":"<node_uuid>"}'12. 获取资源树（物料信息）
curl -s -X GET "$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
curl -s -X GET "$BASE/api/v1/lab/workflow/template/detail/$workflow_uuid" -H "$AUTH"必须使用
/lab/workflow/template/detail/{uuid}，其他路径会返回 404。
14. 按名称查询物料模板
curl -s -X GET "$BASE/api/v1/lab/material/template/by-name?lab_uuid=$lab_uuid&name=<template_name>" -H "$AUTH"返回 data.uuid 为 res_template_uuid，用于 API #15。
15. 创建物料节点
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
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":{...}}'Placeholder Slot 填写规则
placeholder_keys 值 | Slot 类型 | 填写格式 | 选取范围 |

Can I use Host Node in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add deepmodeling/Uni-Lab-OS --skill host-node -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/host-node, .gemini/skills/host-node, .github/skills/host-node and .opencode/skills/host-node in your project.
What does Host Node need to run?
Going by SKILL.md and its folder, Host Node needs the command-line tools its instructions call (curl). Our summary lists: Python 3.
Does Host Node access the network?
SKILL.md names 3 domains. In commands or code: leap-lab.test.bohrium.com, leap-lab.uat.bohrium.com and leap-lab.bohrium.com; the agent is likely to contact these when it follows the instructions. This is read from the text; nothing was executed.
Is Host Node safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Host Node use?
Host Node is published under the GPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Host Node use?
About 1.9k tokens (SKILL.md is roughly 7.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Host Node?
Skills that share tags, products or a category with Host Node: API Designer (Jeffallan/claude-skills, 12k stars), Paperclip (paperclipai/paperclip, 99k stars), Nodejs Backend Patterns (ever-works/ever-works, 158 stars) and OpenAPI to MCP Server (mcp-use/mcp-use, 11k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
