What it does
Cnb is an agent skill from h4dex/opc-nexus. CNB(cnb.cool)云原生构建平台操作:Git 推送、.cnb.yml CI 配置、CNB OpenAPI(Release/Issue/PR)。当需要推送代码到 CNB 远端、修改 CI 流水线、发布 Release 或调用 CNB API 时使用。
Its SKILL.md is about 620 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Backend & APIs, covering OpenAPI specifications. It works with Git, OpenAPI and Android. The repository describes itself as: 开源的企业版的数字员工工作台, OPC-Nexus（One Person Company Nexus）是一款本地优先的桌面 AI Agent 管理器。它为单人公司 / 独立开发者提供统一的 AI 数字员工管理平台 —— 从 Agent 创建、任务编排、多引擎接入，到消息渠道集成、工作流自动化和专家团协作，一站式覆盖。 The licence is MIT.
When your agent uses it
- Tasks that involve OpenAPI specifications
Example prompts
- “/cnb”
Requirements
- Docker
What it can do on your machine
Read from SKILL.md and the folder at commit 0040c25. 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:
gitnpmcurl
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:
api.cnb.coolcnb.coolregistry.npmmirror.com
Also links to:
docs.cnb.cool
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
Cnb loads about 624 tokens when it runs. Until then it costs about 33 tokens; SKILL.md has 81 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.

CNB 平台操作指南
本仓库托管于 CNB:https://cnb.cool/senke/innovation/opc-nexus
认证约定
- Git 远端
origin已内嵌凭据(用户名cnb+ 访问令牌),存于.git/config,不在提交文件中 - 需要令牌时从 remote URL 提取,禁止硬编码到任何被提交的文件:
TOKEN=$(git remote get-url origin | sed -E 's#https://cnb:([^@]+)@.*#\1#')- Git 身份:
liyingjie <y@senke.com>
提交与推送工作流
每完成一个功能:
npm run typecheck && npm test # 必须通过
git add <相关文件>
git commit -m "feat: 功能描述" # 前缀:feat/fix/docs/chore/refactor/test
git push origin master # 推送到 CNB- 提交信息与仓库历史风格一致(见
git log --oneline),一行为主 - 敏感信息(令牌、密钥、Secret)绝不进入提交内容;渠道凭据走 safeStorage,不落盘明文
CI 配置(.cnb.yml)
仓库根目录 .cnb.yml,文档:https://docs.cnb.cool/zh/build/configuration.html
结构:分支名 → 事件(push / pull_request / tag_push)→ 流水线数组
master:
push:
- name: typecheck-and-test
docker:
image: node:22
stages:
- name: install
script: npm ci --registry=https://registry.npmmirror.com
- name: typecheck
script: npm run typecheck
- name: test
script: npm test要点:
- 分支名可用通配:
"$"表示所有分支,"v*"匹配 tag - 每条流水线在独立 Docker 容器中执行;
stages顺序执行,失败即终止 - 可用
imports引入密钥仓库中的环境变量(密钥不明文写入 .cnb.yml) - 常用事件:
push、pull_request、tag_push、api_trigger(手动/API 触发)

Questions about Cnb
What does Cnb do?
CNB(cnb.cool)云原生构建平台操作:Git 推送、.cnb.yml CI 配置、CNB OpenAPI(Release/Issue/PR)。当需要推送代码到 CNB 远端、修改 CI 流水线、发布 Release 或调用 CNB API 时使用。. Cnb is an agent skill from h4dex/opc-nexus.
When should I use Cnb?
Cnb fits situations like: tasks that involve OpenAPI specifications.
How do I install Cnb in Claude Code?
Run `npx skills add h4dex/opc-nexus --skill cnb -a claude-code`. Or copy the skill folder (.claude/skills/cnb in h4dex/opc-nexus) into .claude/skills/cnb in your project. Claude Code loads it when a task matches its description.
How do I install Cnb in Codex?
Run `npx skills add h4dex/opc-nexus --skill cnb -a codex`. Or copy the skill folder (.claude/skills/cnb in h4dex/opc-nexus) into .agents/skills/cnb in your project. Codex loads it when a task matches its description.
Can I use Cnb 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 h4dex/opc-nexus --skill cnb -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/cnb, .gemini/skills/cnb, .github/skills/cnb and .opencode/skills/cnb in your project.
What does Cnb need to run?
Going by SKILL.md and its folder, Cnb needs the command-line tools its instructions call (git, npm and curl). Our summary lists: Docker.
Does Cnb access the network?
SKILL.md names 4 domains. In commands or code: api.cnb.cool, cnb.cool and registry.npmmirror.com; the agent is likely to contact these when it follows the instructions. As links in the text: docs.cnb.cool. This is read from the text; nothing was executed.
Is Cnb 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 Cnb use?
Cnb is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Cnb use?
About 624 tokens (SKILL.md is roughly 2.5k 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 Cnb?
Skills that share tags, products or a category with Cnb: Graphos Factory (apollographql/skills, 117 stars), Datadog Data Source Generator (DataDog/terraform-provider-datadog, 468 stars), Docs CI (jh941213/my-cc-harness, 126 stars) and Docs CI (jh941213/my-cc-harness, 126 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
