How to use Reference Checking in Claude, ChatGPT, Gemini or Grok

Claude upload

  1. Download the skill from its source. A skill is a folder with a SKILL.md file inside; zip that folder if it is not zipped already.
  2. In Claude, open Settings (or Customize), then Skills, then Upload.
  3. Upload the skill ZIP as it is. Don't unzip it.
  4. Check it is switched on.
  5. Test it: start a new chat and type Use reference-checking, then paste what you have.

Team and Enterprise owners may need to allow skills first.

ChatGPT Business, Enterprise or Edu upload

  1. Download the skill from its source. A skill is a folder with a SKILL.md file inside; zip that folder if it is not zipped already.
  2. In the sidebar, click Plugins, then the Skills tab.
  3. Click Create, then Upload from your computer, and pick the skill ZIP.
  4. ChatGPT scans it, then uses it on its own or when you @ mention it.

An admin has to switch skills on for the workspace first.

ChatGPT Plus, Pro or Free paste

  1. Copy the SKILL.md text from the skill's source page (ChatGPT).
  2. In ChatGPT, click Projects, then New project, and name it after the skill.
  3. Open the project's Instructions and paste.
  4. Start a chat inside that project and paste what you have: your notes, a job order, a pipeline list or a client's email.

These plans have no skill upload. A project keeps the instructions for every chat inside it.

Gemini Enterprise upload

  1. Download the skill from its source. A skill is a folder with a SKILL.md file inside; zip that folder if it is not zipped already.
  2. In the Gemini Enterprise web app, click Skills in the menu.
  3. Click +, then Upload skill, pick the skill ZIP and click Import.
  4. Call it with / in a chat, or let Gemini pick it up on its own.

Standard, Plus and Pay-as-you-go editions can upload. An admin has to switch skills on first.

Gemini app paste

  1. Copy the SKILL.md text from the skill's source page (Gemini Gem).
  2. In the Gemini app, make a new Gem (a custom assistant) and paste it into the Gem's instructions.
  3. Chat with that Gem whenever you need the skill.

Grok paste

  1. Copy the SKILL.md text from the skill's source page (Grok).
  2. Paste it into a chat with your Grok Bot. The first line asks it to save the skill with Skill Creator.
  3. Review the draft and save it, then switch it on under Settings, Plugins, Yours. Call it with / in a chat.

Developers folder

  1. Download the skill from its source. A skill is a folder with a SKILL.md file inside; zip that folder if it is not zipped already.
  2. Gemini CLI or Antigravity: unzip into .gemini/skills/ in your project, or ~/.gemini/skills/ for every project.
  3. Claude Code: ~/.claude/skills/, or install a whole pack as a plugin from our GitHub repo. Grok Build: .grok/skills/.

Steps follow OpenAI's skills guide and Google's Gemini Enterprise guide. Menu names change, so check there if a label looks different.

Questions

Is the Reference Checking skill free?

The skill file is published openly by tuanductran under the MIT license. It needs nothing beyond your AI assistant.

Does Reference Checking work in Gemini?

Yes. Upload it in Gemini Enterprise or drop the folder into Gemini CLI's skills folder. In the regular Gemini app, paste its instructions into a Gem.

Can I trust it with my data?

It has no scripts and sends nothing anywhere. Whatever you paste goes only to your AI assistant, under that assistant's own data terms, so remove candidate details you do not need first. It can still steer how the assistant answers, so read it before you use it.
