UnderAutomation agent skills

This repository contains the agent skills of the UnderAutomation robot SDKs, for AI coding agents such as Claude Code, Codex, GitHub Copilot and Cursor. A skill gives the agent the documentation, the API reference and the code examples of one SDK in one language (C# or Python), at the version of the SDK.

With the skill, the agent can answer questions such as "why do I get this exception?" or "what is the difference between SNPX and CGTP?", and write code such as "write an app that reads the position registers".

The version of a plugin is the version of the SDK it documents. Install the skill of the language of your project only: the .NET API uses PascalCase and the Python API uses snake_case.

Installation

Replace fanuc-csharp with the plugin of your SDK and language.

Claude Code

claude plugin marketplace add underautomation/skills
claude plugin install fanuc-csharp@underautomation

Inside a Claude Code session, the same commands are /plugin marketplace add underautomation/skills and /plugin install fanuc-csharp@underautomation. Add --scope project to claude plugin install to share the plugin with the other developers of the project.

Codex

codex plugin marketplace add underautomation/skills

Then open Codex, run /plugins, select the UnderAutomation marketplace and install fanuc-csharp.

Other agents (npx skills)

With Node.js installed, skills installs the skill for GitHub Copilot, Cursor, Gemini CLI, OpenCode and about 70 other agents:

npx skills add underautomation/skills --skill underautomation-fanuc-csharp

Add -y to skip the questions, -a <agent> to choose the agent and -g to install for the user instead of the project.

Manual installation

Download the zip of the skill from the latest release, for example underautomation-fanuc-csharp.zip, and extract it into the skills folder of your agent. The zip contains the folder underautomation-fanuc-csharp/.

Agent	Project folder	User folder
Claude Code	.claude/skills/	~/.claude/skills/
Codex	.agents/skills/	~/.agents/skills/
GitHub Copilot	.agents/skills/	~/.copilot/skills/ or ~/.agents/skills/
Cursor	.agents/skills/	~/.cursor/skills/ or ~/.agents/skills/

A project folder is relative to the root of the project. On Windows, ~ is %USERPROFILE%.

The URL https://github.com/underautomation/skills/releases/latest/download/<skill>.zip always gives the last version. Each release also contains <plugin>-plugin.zip, the complete plugin folder.

Check the version

The frontmatter of SKILL.md gives the SDK version that the skill documents (metadata.sdk-version). Compare it with the package of your project:

• C#: dotnet list package
• Python: pip show UnderAutomation.<Brand>, for example pip show UnderAutomation.Fanuc

When the versions differ, update the plugin (claude plugin update fanuc-csharp@underautomation, npx skills update) or download the zip again. The agent also does this check before it writes code.

Content of a skill

underautomation-fanuc-csharp/
  SKILL.md                  when to use the skill, protocol choice, connection, license, motion safety, rules
  references/pages/         one file per page of the documentation, with the code of the language
  references/api/           every public type and member of the SDK, one line each
  references/errors.md      exceptions of the SDK and what to check

The skills are generated from the documentation of underautomation.com at each release of an SDK. Do not change the files of plugins/ by hand: report a problem in the issues and it will be fixed in the documentation.

Repository layout

.claude-plugin/marketplace.json     Claude Code marketplace, also read by npx skills
.agents/plugins/marketplace.json    Codex marketplace
plugins/<plugin>/
  .claude-plugin/plugin.json        Claude Code manifest
  .codex-plugin/plugin.json         Codex manifest, same name and version
  skills/<skill>/SKILL.md
.github/workflows/ci.yml            validation, zips and release at each push to main

To publish a new plugin, copy its folder into plugins/ and add one entry to each marketplace.json, with the same values as the other entries. The CI checks that the two marketplaces list the same plugins and that the two manifests of a plugin have the same name and version.

The SDKs themselves are commercial products with their own license agreement, for example underautomation.com/fanuc/eula. Installing a skill does not give a license of the SDK. Each SDK has a 30-day trial that starts at the first use. Prices and license keys: underautomation.com.
