Questions
Which AI tools can use a skill?
Any tool that supports the Agent Skills format, including Claude, Claude Code, ChatGPT and Codex, GitHub Copilot, VS Code, Cursor and Gemini CLI. Some tools need each skill installed separately, and the install notes cover each one you use.
How is a skill different from a custom GPT?
A custom GPT lives inside ChatGPT. A skill is a folder of files you own, and it moves with you between tools that support the format.
Can we edit a skill?
Yes. The instructions are plain text and the scripts are included.
Can you build a skill for our procedure?
Yes. Custom skills start from your documents, examples and standards.
